The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.

FIELD OF THE INVENTION

The invention relates to a computerized exercise fitness program designing system and method for assisting in execution and recording of performance information.

BACKGROUND OF THE INVENTION

A consistent fitness regiment is universally accepted by medical authorities as being instrumental to longevity and good health. There are currently several devices available that monitor an individual exercising on an exercise apparatus. Examples of these are U.S. Pat. Nos. 4,493,485, 4,409,992, and 4,408,183. The problem with these devices is that they are limited to recording the performance the user decides to achieve and provide no instruction on the performance the user should achieve. For example, U.S. Pat. No. 4,493,488 provides a predetermined pace for the user regardless of the user's actual fitness level. Additionally, the aforementioned devices provide no indication of past performance from which a trend can be interpolated. U.S. Pat. No. 4,817,940 does provide the capability to record past performance but makes no provision to automatically calculate future performance requirements based upon that stored information. Additionally U.S. Pat. No. 4,817,940 requires that each piece of exercise equipment be instrumented in order to be accessible by the device.

A key element to a fitness program is the ability to continually challenge the body physically. When a person has performed an exercise at a consistent level, the muscles tend to acclimate to the particular exercise and plateau at the level of development required to maintain the exertion level. In order to advance the development of the muscles involved, the exertion level must be increased at specific intervals. Without continual professional instruction, most amateur fitness enthusiasts lack the basic knowledge to determine when and by how much to advance their workout parameters to achieve maximum effectiveness.

The System described herein allows the Trainer to impart a training philosophy to each exercise. The Trainer can specify up to four actions to be performed, automatically, on specified exercise dependent parameters (pounds of weight, repetitions, sets, etc.) when specified events (completed routines, elapsed days, etc.) occur. The Trainer can have a parameter increase, decrease, or the exercise completely removed from the workout when the specified event occurs. The events are user selectable using dynamically compiled lists and numeric entry fields. Each time client's daily workout routine is requested, the System will compute the new parameters for each exercise using the exercise's philosophy settings, the performance of the last workout session, and the current date. The end result is a workout program that adapts to the client's actual workout performance achieving the desired result without the client possessing a prerequisite knowledge of exercise training or cost of a private trainer each workout session.

The current most popular method of displaying and recording an exercise fitness program involves a cardboard sheet depicting a list of exercises, initial setup parameters, and columns representing workout sessions. The user must manually mark the repetitions, sets, or other work performed for each corresponding exercise. The end result is a very crowded matrix that reveals little trend information and requires manual computation to determine future performance goals. Storage of these sheets may become cumbersome, especially for a large client population.

The System will eliminate the paper workout sheet and replace it with compact portable battery powered computerized Digital Training Assistants (DTAs). Each DTA is dynamically programmed with the user's own fitness routine calculated for the specific workout session. The DTA unit will interactively instruct the user on both the sequence of exercises to be performed as well as the exercises setup and desired performance parameters. A keypad interface to modify parameters is provided to permit recording of the actual work performed. The resultant exercise information is downloaded back to the System where it becomes a permanent part of the user's individual workout performance history database file. The file's data will be used in the computation of the next workout session's exercise performance parameters.

Determining past performance trends using the traditional paper method of parameter recording requires manually graphing data points. This becomes increasingly impractical with increasing number of workouts. The user will often not increase the workout parameters over time or even worse, increment parameters regardless of the actual fitness level attained.

By utilizing the detailed exercise data in the client's individual workout performance history database file, several reports and graphs can be produced with the speed and accuracy of a computerized system. This gives a new level of instant feedback not previously available in the Fitness Club environment. The client is now able to determine the apparent effectiveness of his workout routine and become more connected to his workout by virtue of the near real-time reporting capability of the System. Enthusiasm and involvement are both enhanced.

A common problem with personal trainers at a fitness club is that each trainer will impart their own individual exercise fitness philosophy onto a client. The result being that any two clients trained by different trainers will have differing fitness programs and varied results. There is a loss of standardization within the club and each new trainer adds to the problem. A method of standardizing the training philosophies using a collective expertise is needed within the industry.

The proposed system will allow the Head Trainer to impart his/her training expertise to each Assistant Trainer by mandating that the trainers implement one of the stored exercise routine templates when training a client. The System will allow different exercise templates to be constructed using the equipment and exercises found at the facility. Each template's exercises may have corresponding parameter increasing/decreasing philosophies designed by the Head Trainer as well.

Accuracy in reporting a client's workout performance is another problem encountered by trainers. When a client is not being monitored personally by a trainer, the client is then responsible for remembering and recording the actual work performed. The client must also be aware of the parameters to record and the correct terminology. The Trainer must then be apprised of the client's performance so that he/she may make adjustments as required.

The DTA units allow the client to easily record the actual work performed. Even if a client is unable to complete the exercise as prescribed and displayed, the actual work performed is easily input to the DTA using a numeric keypad and associated function keys. The DTA will prompt the client to make the entry and alert him of any input errors with the required corrective action. The edited workout routine is then downloaded, with computer accuracy, to the System. The changes are instantly noted by the System and adjustments are automatically made.

Currently, at a moderate sized fitness club, the client to trainer ratio is worse than 40 to 1. Most client's are reluctant to incur the additional cost of a Personal Trainer at each session as well as the inconvenience of having to schedule workouts around a trainer's availability. The result is a vast majority of a club's clientele are not taking advantage of the trainers. A potential loss of revenue for the club.

When utilizing the System, the trainers effectively multiply their presence and utility. This is accomplished by having many clients operating the System and DTAs, following the trainer's designed workout program. The automatic parameter philosophy incrementing/decrementing function will ensure that the client is receiving the maximum benefit of the exercise program as if the trainer were always present to make those adjustments in person. An initial trainer/client session for setup and instruction on usage will increase facility's trainer exposure and periodic fitness program checkups ensure further trainer usage.

Currently, a trainer would have to interview and review the workout sheets for several clients to determine if a particular training regiment is performing as prescribed. This is a labor intensive endeavor demanding a large portion of the trainer's work hours. It is to both the trainer's and client's benefit to maximize the effectiveness of a workout routine.

The system will allow the trainer to asses the effectiveness of a workout program by virtue of the system's recording and reporting capabilities combined with the ability to simultaneously look at several different client's and their corresponding demographics. Performance graphs give easily understandable trend analysis useful in determining the effectiveness of the regiment. The trainer may now fine tune the routine to achieve maximum effectiveness.

The comprehensive database capabilities of the system will allow the creation of equipment usage reports charting the number of clients using a particular piece of exercise equipment during a particular week throughout a calendar year this will provide more accurate maintenance scheduling and equipment utilization data.

Demographic and medical information for a client is instantly available to the Trainer as well as the ability to create reports for membership analysis. Such information is very useful in planning promotions and configuration of the facility to better match the client's requirements.

SUMMARY OF THE INVENTION

The System is composed of both a computer software application program and custom computer hardware. The application software, as it currently exists, operates under the Microsoft.RTM. Windows.TM. 3.1 (or above) personal computer operating system. The software constructs and utilizes a variety of Xbase.TM. type database files to store and retrieve information about clients, Trainers, facility configuration, system preferences, and client workout routines. Computational capabilities include processing exercise workout parameters to produce a dynamic daily workout regiment. Graphical objects are used to implicitly guide the user in operation of the software's embedded functions.

The application software will produce, as one of its prime functions, a workout routine consisting of exercise names and their associated setup and parametirc data. The routine is interactively constructed for a specified client. The routine can then be formatted and electrically transferred to a Digital Training Assistant (DTA). The DTAs utilize a 16-alphanumeric character display and keypad to instruct the user on execution of the workout stored within. The DTAs also allow the various exercise parameters to be modified as needed. Ancillary functions include a stopwatch timer, interactive pulse recording function, and body weight input facility.

The executed exercise routine is eventually transferred from the DTA back to the System where it is reincorporated into the client's database files. The exercise routine is uploaded and downloaded to a DTA by insertion into a special DTA Programming Stand. The DTA Programming Stand is connected to the host computer via an RS-232C interface and converts the electrical signal levels to those compatible with the DTA's own serial interface. Commands from the host computer to the DTA will initiate either the upload or download action. Indicators on the Programming Stand will display power and programming status. Several DTA units may be used with a single DTA Programming Stand all under control of a single software system

A 1/4" maximum thick surface can now be inserted between the clip and the DTA back surface. When the pressure to the activation depression 543 is released, as sown in Detail 3, The expansion spring 539 is stretched, the clip moves along the pivot slot 545 and the compression spring 538 is allowed to decompress further bringing the clip parallel with the inserted surface. The grip points 542 are now in even contact with the surface providing positive grip. To release the surface, pressure is again applied to the activation depression 543 and the surface is removed.

An alternative design is to replace the expansion spring 539 with a second compression spring 541 located inside the pivot slot 545. The effect is the same but the design is more compact.

D. System Component Electrical Description

Referring to the drawings:

FIG. 7 Shows a detailed circuit diagram of the Version-A Digital Training Assistant unit.

Power is activated by closing SPST switch 89. The two CR2025 Lithium Coin Cell Batteries 90 supply +6 VDC to the +5 VDC regulator (LT1121CZ-5) 85 and +3.3 VDC regulator (LT1121CZ-3.3) 86. Each regulator has a single 1.0 uF filter capacitor 87 & 88.

The Resistor-Capacitor power-on reset circuit constructed with a diode 82, 100K resistor 83, and 1 uF capacitor 84 combine to give an RC constant of 100 mS. The reset signal is sent to the reset input of the 8-Bit Microcontroller 91.

The 8-bit microcontroller 91 is a Hitachi H8/329 Series single-chip microcomputer (microcontroller). The microcontroller contains 32 Kbytes of Read Only Memory (ROM), 1 Kbyte of Random Access Memory (RAM), one 16-bit free running timer, dual 8-bit timers, a serial communications interface, an A/D converter, and extensive bit controllable I/O ports.

E. DTA Firmware Description

The microcontroller contains a software program resident in the 32K Read Only Memory (ROM). This program is responsible for the operational interface of the DTA unit encompassing LCD display functions, keypad interface, and serial data transmission/reception. The following paragraphs and figures describe the DTA firmware operation. Where noted, differences between the Version-A and Version-B DTA units are explained

Prior to firmware explanations, a brief discussion of the software interface between the System application software and the DTA is in order.

An exercise routine is formatted into a contiguous digital data stream composed of distinct blocks. The individual bytes of the blocks conform to a strict format as described herein. The routine is compiled by the System application software as the output of a specific function and transmitted to the DTA using the DTA Programming Stand. Once received by the DTA, the DTA's microcontroller and associated firmware program can access, display, and modify the data in the exercise routine as required. The entire modified routine is then eventually transmitted back to the System for reincorporation.

The exercise routine is proceeded by a header block. The block is composed of nineteen bytes describing the client's name and membership number, body weight and pulse measurement. A master Header Command byte determines what mode the DTA is operating under:

00=Normal Mode (normal operation)

02=Learn Mode (allows changes in equipment mechanical/ergonomically settings)

Following the header bytes are the individual Exercise Description Blocks (EDB). The DTA's RAM will support as many exercise blocks as will fit into 960 bytes. The System application software is charged with limiting the formatted exercise routine to this physical limit.

There are six different types of EDBs. These blocks describe the individual exercises that make up the exercise routine. Those blocks specified as having a "Table Lookup" use a code number in place of character bytes that represent the 16-character maximum exercise description displayed by the DTA. A corresponding table of exercise description strings is hardcoded in the DTA's microcontroller's ROM. This method conserves valuable RAM space when an exercise included in the table is used in place of a user defined exercise name.

The following tables describe the formats of the uploaded workout routine data package and associated EDBs:

FIG. 11 Shows a flow diagram of both Version A & B DTA firmware power-on sequence.

When power is applied to the DTA's microcontroller, the microcontroller's program execution unit will reset and begin execution at Power On 174. The program then initializes the microcontroller 175 setting up various internal registers and the interrupt vector table. Next the program will initialize the OEM LCD Display Module's T7934 LCD Controller 176.

Following initialization, the program will perform some internal self tests. The registers located in the microcontroller are tested for both read and write capability 177. If the any part of the test fails 178, the alarm is sounded and a message is displayed on the LCD with a specific code number indicating the failed register 179. The program jumps to an infinite loop 180 causing a general program abort. The DTA must be powered off then on to reset.

The 1 Kbyte RAM is tested next 181 using seven different bit patterns written to and then read from all the RAM locations. If an error is detected at any stage of the test 182, the alarm is sounded and a message is displayed on the LCD with a specific code number indicating the failed location 183. The program jumps to an infinite loop 184 causing a general program abort. The DTA must be powered off then on to reset.

The keypad connected to the microcontroller via the I/O ports is tested to determine if any keys are stuck active 185. If a key is detected as being stuck on 186, the alarm is sounded and a special message is displayed on the LCD with the offending key number 187. The test repeats until the key is unstuck.

Once the testing has completed successfully, the start message is displayed: "Physical Genius" 189 followed by: "Ready to Program" message. The program enters a loop 190 awaiting the reception of a exercise routine data upload.

While in the waiting loop 190, the program checks for any receiver errors 191. If detected, the alarm is sounded and a special message is displayed 192 describing the offending error. The routine will reset awaiting reception of more data.

When a valid upload of a workout routine is received, a new message is displayed 193 instructing the user to advance the program with the NEXT key. The program now enters a waiting loop 195 looking for a NEXT key activation. Upon detection of the key, the program will process the keypad key request 194.

From this point on, the program is event driven. Keypad requests will determine what function the program executes next and further keypad requests control the sub-functionality therein.

When a key is activated, an interrupt signal is generated to the microcontroller which activates a special interrupt processing routine. The keyboard I/O port pins are scanned and the activated key's signal is detected. The keyboard interrupt routine will return a number representing the key that was detected as being active.

FIG. 12 Shows a flow diagram of both Version A & B DTA firmware NEXT, PREV, ENTER, NAME, PULSE, and WEIGHT keypad key activation sequences.

When the NEXT Key has been detected 196, the program will locate the next exercise description block 197. If while searching for the next EDB, the program encounters the Footer byte indicating the end of the upload block 198, a special message is displayed 199 instructing the user to hit the PREV key. The program waits until the PREV key is hit 201. When detected the program will execute the display sequence routine 200 for the EDB that was being displayed prior to the NEXT key activation.

The exercise display sequence routine 200 will parse out the elements of the exercise description block (EDB) and display them on the LCD display. Where indicated, if the associated exercise parameter is 0, the parameter's display will be omitted. The following tables depict the display sequence for each main type of exercise:

    ______________________________________


The sequence is repeated three times 202 after which the microprocessor will enter its low power sleep mode 203 until a keypad key is pressed and thus the activation interrupt is detected. The sequence will then restart at the top. Any time during the display sequence, the program will be able to process keypad key activation interrupts and act accordingly.

When the PREV Key has been detected 204, the program will locate the previous EDB 205. If while searching for the previous exercise description block, the program advances beyond the beginning of the exercise description space 206, a special message is displayed 207 instructing the user to hit the NEXT key. The program waits until the NEXT key is hit 209. When detected the program will continue to the display sequence routine of the EDB being displayed prior to activating the PREV key 208.

The sequence is repeated three times 210 after which the microprocessor will enter its low power sleep mode 211 until a keypad key is pressed and thus the activation interrupt is detected. The sequence will then restart at the top.

If the ENTER key is detected 212, the program must first decide the context of the key's activation 213. If the key is used as data input confirmation, the data is then validated according to the context of the data entry 215. If there is a detected entry error 216, a special message is displayed indicating the error and corrective action 217. The program then repeats the original data entry prompt routine 218 followed by another ENTER key detection 212. If the data was determined as valid and correct it is formatted and stored in the appropriate location in the current EDB or Header Block location 219. The program then continues from where it was originally interrupted or made the function call 220.

If the context of the ENTER key was not as data input confirmation then it is used to mark the current EDB as being completed 214. The program then continues at Marker A.

If the NAME key is detected 221, the client's name characters are extracted and reconstructed as ASCII characters 222 from the Header Block bytes 7 through 16. The bytes are then sent to the LCD Display Controller for a ten second display 223. Following the interval, the program returns to the point of interruption 224.

If the WEIGHT key is detected 225, the weight entry function is activated with the original weight value stored in the uploaded Header Block extracted 226 from bytes 17 and 18. The bytes are converted to ASCII and sent to the LCD Display Controller for display 227. The program then prompts for a new entry 228 allowing a three digit plus one decimal place value. The program continues at Marker B for ENTER key processing 229. When successfully concluded, the program will return to the point of interruption 230.

If the PULSE key is detected 231, the pulse entry function is activated. The function will interactively instruct, via the LCD display, the user on how and when to measure his pulse 232. The program will then start a ten second timer 233. At the conclusion of the time interval, the alarm sounds and the program prompts for the new measured pulse count entry 234. The program continues at the Marker B for ENTER key processing 235. When successfully concluded, the program will return to the point of interruption 236.

FIG. 13 Shows a flow diagram of the Version-A DTA firmware GROUP keypad key activation sequence.

The GROUP key is used to advance the exercise program out of the predetermined sequence to the next available exercise in the specified group (Aerobic Anaerobic, or Stretch). If the GROUP key is detected 237, the word "Aerobic" is displayed 238. A three second timer is started 239 and if the GROUP key is detected again 240 within the interval, the program will locate the first available Aerobic type EDB 241. The display sequence is activated at Marker C, 247. If no uncompleted Aerobic EDB is found 243, a special error display message is used 245 and the program returns to the point of interruption 248.

If the three second timer is allowed to elapse 242, the word "Anaerobic" is displayed 244. A three second timer is started 246 and if the GROUP key is detected again 249 within the interval, the program will locate the first available Anaerobic type EDB 250. The display sequence is activated at Marker C 256. If no uncompleted Anaerobic EDB is found 252, a special error display message is used 254 and the program returns to the point of interruption 257.

If the three second timer is allowed to elapse 251, the word "Stretch" is displayed 253. A three second timer is started 255 and if the GROUP key is detected again 258 within the interval, the program will locate the first available Stretch type EDB 259. The display sequence is activated at Marker C 263. If no uncompleted Stretch EDB is found 261, a special error display message is used 262 and the program returns to the point of interruption 254.

If the three second timer is allowed to elapse 260, the sequence starts over again with displaying "Aerobic" 238.

FIG. 14 Shows a flow diagram of the Version-A DTA firmware DURATION, SETTINGS, PLATES/LBS (DISTANCE), REPS. (SPEED), and SETS (LEVEL) keypad key activation sequences

In the Version-A DTA unit firmware, selected keys perform dual functions depending upon the context in which they are activated

If the DURATION key is detected 265, the program will extract the duration setting from the current EDB block 266 and allow a new input 267. The program continues at B Marker for ENTER key processing 268. When successfully concluded, the program will return to the point of interruption 269

If the SETTINGS key is detected 270, the program will first check if the current mode is Learn and that the EDB is not a Stretch type exercise. If otherwise, the function is not entered. If true, the program will extract the mechanical/ergonomically settings 271 from the EDB and display the first setting 272. The program will now allow input of a new setting 273. The program continues at Marker B for ENTER key processing 274. When successfully concluded, the program will check to see if there is another setting to adjust 275. If so, the process is repeated for the remaining settings 272. If finished, the program will return to the point of interruption 276

If the PLATES/LBS (DISTANCE) key is detected 277, the program will first determine the context by examining the EDB for Aerobic type exercise 278. If Aerobic, the program will extract and display the Distance value 279. The program next allows the input of a new distance setting 281. The program continues at Marker B for ENTER key processing 283. When successfully concluded, the program will return to the point of interruption 285 If the EDB was Stretch 287, a special error message is displayed 288 and the program will return to the point of interruption 289. If the program determines the EDB is Anaerobic, the program will extract and display the Pounds/Plates value 280. The program next allows the input of a new Pounds/Plates setting 282. The program continues at Marker B for ENTER key processing 284. When successfully concluded, the program will return to the point of interruption 286

If the REPS. (SPEED) key is detected 290, the program will first determine the context by examining the EDB for Aerobic type exercise 291. If Aerobic, the program will extract and display the Speed value 292. The program next allows the input of a new speed setting 294. The program continues at Marker B for ENTER key processing 296. When successfully concluded, the program will return to the point of interruption 298

If the program determines the EDB is not Aerobic, the program will extract and display the Repetitions value 293. The program next allows the input of a new Repetitions setting 295. The program continues at Marker B for ENTER key processing 297. When successfully concluded, the program will return to the point of interruption 299

If the SETS. (LEVEL) key is detected 300, the program will first determine the context by examining the EDB for Aerobic type exercise 301. If Aerobic, the program will extract and display the Level value 302. The program next allows the input of a new level setting 304. The program continues at Marker B for ENTER key processing 306. When successfully concluded, the program will return to the point of interruption 308

If the program determines the EDB is not Aerobic, the program will extract and display the Sets value 303. The program next allows the input of a new Sets setting 305. The program continues at Marker B for ENTER key processing 307. When successfully concluded, the program will return to the point of interruption 309

FIG. 15 Shows a flow diagram of the Version-A DTA firmware TIMER, START/STOP (DURATION), and RESET (CALORIES) keypad key activation sequences.

If the TIMER key is detected 310, the program enters the count down timer function. The program first displays the "Set Minutes" prompt 311. Entry of a minutes setting is enabled 312. The program continues at Marker B for ENTER key processing 313. When successfully concluded, the program will now display the "Set Seconds" prompt 314. Entry of a seconds setting is enabled 315. The program continues at Marker B for ENTER key processing 316. When successfully concluded, the program now waits for a keypad key activation 317. If the START/STOP (INCLINE) key is detected the timer and display time function is started 320.

For other detected keys, the program checks if it was a numeric key 318, if so the program ignores the key activation 317, If it is a function key, the program will return to the point of interruption 319.

After the timer and display time function has started 320, the program will also look for a key activation 321. Any other key but the START/STOP (INCLINE) key will be ignored. If the START/STOP (INCLINE) key is detected, the timer and time display are stopped 322. If the TIMER key is detected again 323, the program will continue at Marker E. If the RESET (CALORIES) key is detected, the timer is reset to the initial values 326 and program execution continues at 317. If the START/STOP (INCLINE) key is detected, the program execution continues at Marker D.

In the absence of the START/STOP (INCLINE) key detection, the timer will continue to count down to 00:00 while displaying the current remaining time. When the timer has reach 5 remaining seconds 327, the alarm will beep on each subsequent second 328. When the timer expires 329, the alarm will beep several times and the timer stop.

At this point, the program is waiting for another key activation 331. If the TIMER key is detected, the program continues execution at Marker E. If the RESET (CALORIES) key is detected, the program will reset the timer to the initial values 326 and continue execution at 317. If a numeric key was detected 332, the key activation is ignored. If it was a function key, the program will return to the point of interruption 333.

The START/STOP (INCLINE) and RESET (CALORIES) keys have dual functions. Following are descriptions of their alternative functions

If the START/STOP (INCLINE) key is detected 334, the program determines what context it is currently in 336. If the timer is active, the timer functionality is used 335. If not in timer mode, the program checks to see if the current EDB is Aerobic 337. If not then a special error message is displayed 339 and the program will return to the point of interruption 341.

For an Aerobic EDB, the program will extract and display the Incline value 338. The program next allows the input of a new incline setting 340. The program continues at Marker B for ENTER key processing 342. When successfully concluded, the program will return to the point of interruption 343

If the RESET (CALORIES) key is detected 344, the program determines what context it is currently in 346. If the timer is active, the timer functionality is used 345. If not in timer mode, the program checks to see if the current EDB is Aerobic 347. If not then a special error message is displayed 349 and the program will return to the point of interruption 351.

For an Aerobic EDB, the program will extract and display the Calories value 348. The program next allows the input of a new calories setting 350. The program continues at Marker B for ENTER key processing 352. When successfully concluded, the program will return to the point of interruption 353

FIG. 16 Shows a flow diagram of both Version A & B DTA firmware Serial Port Interrupt Routine sequences.

The microcontroller's serial communications interface will generate an interrupt when a byte has been received 354. The interrupt routine will check to see if any receive errors were accrued 355. If so a special error message is displayed 356 and the program returns to the point of interruption 374.

If there are no errors, the byte is examined to see if it is a download command 357. If so the processing continues to process a download starting at 375. If not then the program checks to see if a previous upload has been received 358. If so, the interrupt routine is exited and the program returns to the point of interruption 374.

If no previous upload has been received, the program checks to see if the byte was a valid master header byte 359. If not then display special error message and the program returns to the point of interruption 374.

If a valid master header byte is detected, the remaining header block bytes are received and put into a buffer in RAM 361. After the header bytes have been received, the program will examine the next byte received and check if it is an Aerobic EDB header byte 362, if so the program will determine how many more bytes in the block, receive them, and store in RAM buffer 363.

If the EDB header byte was not Aerobic, the program checks to see if it was Anaerobic 364. if so the program will determine how many more bytes in the block, receive them, and store in RAM buffer 365.

If the EDB header byte was not Anaerobic, the program checks to see if it was Stretch 366. if so the program will determine how many more bytes in the block, receive them, and store in RAM buffer 367.

If the EDB header byte was not Stretch, the program checks to see if it was the Footer byte 368. if not the program will display a special error message 383 and returns to the point of interruption 374.

If the Footer byte is detected, the entire received buffer is modulo-256 checksummed 369. The result is compared to the embedded checksum value that followed the Footer byte in the block 370. If there was a mismatch, the program displays a special error message 371, sets a failure flag 373 and returns to the point of interruption 374. If the checksum test passes, the received valid flag is set 372 and the program returns to the point of interruption 374.

For the download command received case, the entire exercise routine block (from master header byte to Footer byte) is modulo-256 checksummed 375 and the result appended as the last byte in the block 376. The entire block is then transmitted out the serial interface one byte at a time 377. When the transmitter is detected as empty 378, the next byte is transmitted. When the last byte has been detected 379, the byte is transmitted 381 and the program returns to the point of interruption 382.

FIG. 17 Shows a flow diagram of the Version-B DTA AEROBIC, ANAEROBIC, and STRETCH keypad key activation sequences

The Version-B DTA unit expands the Version-A DTA's GROUP key into the three separate exercise groups selection buttons; Aerobic, Anaerobic, and Stretch

If the AEROBIC key is detected 384, the program will start at the first EDB and searches for the first uncompleted Aerobic exercise 385. If no uncompleted aerobic exercise is found 386, a special error message is displayed 387 and the program returns to the point of interruption 389.

If an uncompleted Aerobic exercise is found, the exercise display sequence routine 388 will parse out the elements of the EDB and display them on the LCD. If the exercise parameter is 0, its display may be omitted. The display sequence is as follows:

    ______________________________________


The sequence is repeated three times 390 after which the microprocessor will enter its low power sleep mode 391 until a keypad key is activated and the resultant activation interrupt is detected. The sequence will then restart at the top.

If the ANAEROBIC key is detected 392, the program will start at the first EDB and searches for the first uncompleted Anaerobic exercise 393. If no uncompleted anaerobic exercise is found 394, a special error message is displayed 395 and the program returns to the point of interruption 396.

If an uncompleted Anaerobic exercise is found, the exercise display sequence routine 397 will parse out the elements of the exercise description block and display them on the LCD. If the exercise parameter is 0, its display may be omitted. The display sequence is as follows: 

    ______________________________________

    ______________________________________


The sequence is repeated three times 398 after which the microprocessor will enter its low power sleep mode 399 until a keypad key is activated and the resultant activation interrupt is detected. The sequence will then restart at the top.

If the STRETCH key is detected 400, the program will start at the first EDB and searches for the first uncompleted Stretch exercise 401. If no uncompleted stretch exercise is found 402, a special error message is displayed 403 and the program returns to the point of interruption 404.

If an uncompleted Stretch exercise is found, the exercise display sequence routine 405 will parse out the elements of the exercise description block and display them on the LCD. If the exercise parameter is 0, its display may be omitted. The display sequence is as follows:

The sequence is repeated three times 406 after which the microprocessor will enter its low power sleep mode 407 until a keypad key is activated and the resultant activation interrupt is detected. The sequence will then restart at the top.

FIG. 18 Shows a flow diagram of the Version-B DTA firmware stopwatch START/STOP and LAP/RESET key activation sequences

If the START/STOP key is detected 408, the program will first determine if the timer is already running 409. If so, the timer is stopped 410 and the program will wait for another key activation 411. If the next detected key activation is a function key, the program returns to the point of interruption 415. If the next detected key activation is a numeric key 412, the key is ignored. If the next key detected is the LAP/RESET key, the timer is reset to its initial value 416 depending if it was in count down or count up mode. If the next key detected is the START/STOP, the timer is re-enabled 413 and the timer continues.

If the timer was not running initially when the START/STOP key is detected, the "Set Minutes" prompt 414 is displayed. The program waits for another key activation 417. If the START/STOP key is activated, the timer goes into its count up mode 418. If a digit is pressed, the program will accept a minutes setting 419. Any other key will be ignored.

Following Inputting minutes, the program continue at Marker B for ENTER key processing 420. Upon completion of entering a valid minutes setting, the program will prompt for seconds input 421 & 422. The program continues at Marker B for ENTER key processing 423. Upon completion of entering a valid seconds setting, the program waits for another key activation 424. If the LAP/RESET key is detected, the program resets the timer function and redisplays the "Set Minutes" prompt 414. If the START/STOP key is detected, the count-down timer mode is started 425 and the program displays the elapsed time while waiting for time-out or another key activation 429.

If the LAP/RESET key is activated, the program will disable the display function while maintaining the timer 428. The program will wait for the LAP/RESET key activated again 427. When detected, the display function is re-enabled 426.

If the START/STOP key is activated, the timer is stopped 430 and processing continues at Marker F 431.

Any other key will be ignored. The program will monitor the count in count-down mode looking for the last 5-seconds remaining 432. When detected, the alarm will beep on each second 433. When the timer expires 434, the alarm will sound several beeps and the timer is stopped 435. Processing then continues at Marker F 436.

FIG. 19 Shows a flow diagram of the Version-B DTA firmware PLATES/LBS, REPS., SETS, DISTANCE, DURATION, SPEED, INCLINE, LEVEL, and CALORIES keypad key activation sequences

On the Version-B DTA, each function has an individual key although the actual signal to the microprocessor may be shared. The context in which it is activated will distinguish the desired function.

If the PLATES/LBS key is detected 437, the program checks to see if the EDB is Anaerobic 438, if not then a special error message is displayed and the program resumes at the point of interruption 439. If so, the program will extract the current plates/lbs value and display it 440. The program will now accept a new value 441 and then continue at Marker B for ENTER key processing 442. Upon completing a valid input, the program resumes at the point of interruption 442.

If the REPS. key is detected 458, the program checks to see if the EDB is Aerobic 459, if so then a special error message is displayed and the program resumes at the point of interruption 460. If not, the program will extract the current repetitions value and display it 461. The program will now accept a new value 462 and then continue at Marker B for ENTER key processing 443. Upon completing a valid input, the program resumes at the point of interruption 464.

If the SETS key is detected 479, the program checks to see if the EDB is Aerobic 480, if so then a special error message is displayed and the program resumes at the point of interruption 481. If not, the program will extract the current sets value and display it 482. The program will now accept a new value 483 and then continue at Marker B for ENTER key processing 484. Upon completing a valid input, the program resumes at the point of interruption 485.

If the SPEED. key is detected 444, the program checks to see if the EDB is Aerobic 445, if not then a special error message is displayed and the program resumes at the point of interruption 446. If so, the program will extract the current speed value and display it 447. The program will now accept a new value 448 and then continue at Marker B for ENTER key processing 449. Upon completing a valid input, the program resumes at the point of interruption 450.

If the DISTANCE key is detected 465, the program checks to see if the EDB is Aerobic 466, if not then a special error message is displayed and the program resumes at the point of interruption 467. If so, the program will extract the current speed value and display it 468. The program will now accept a new value 469 and then continue processing at Marker B 470. Upon completing a valid input, the program resumes at the point of interruption 471.

If the INCLINE key is detected 486, the program checks to see if the EDB is Aerobic 487, if not then a special error message is displayed and the program resumes at the point of interruption 488. If so, the program will extract the current incline value and display it 489. The program will now accept a new value 490 and then continue at Marker B for ENTER key processing 491. Upon completing a valid input, the program resumes at the point of interruption 492.

If the LEVEL key is detected 451, the program checks to see if the EDB is Aerobic 452, if not then a special error message is displayed and the program resumes at the point of interruption 453. If so, the program will extract the current level value and display it 454. The program will now accept a new value 455 and then continue at Marker B for ENTER key processing 456. Upon completing a valid input, the program resumes at the point of interruption 457.

If the CALORIES key is detected 472, the program checks to see if the EDB is Aerobic 473, if not then a special error message is displayed and the program resumes at the point of interruption 474. If so, the program will extract the current calories value and display it 475. The program will now accept a new value 476 and then continue at Marker B for ENTER key processing 477. Upon completing a valid input, the program resumes at the point of interruption 478.

If the DURATION key is detected 493, the program will extract the current duration value and display it 494. The program will now accept a new value 495 and then continue at Marker B for ENTER key processing 496. Upon completing a valid input, the program resumes at the point of interruption 497.

F. Application Software Description

The application software, henceforth referred to as Physicalc, is described below with reference to the drawings specified. Sample screens from the program are included for clarity.

FIG. 20 Shows a connectivity diagram for the application software program depicting I/O screens and database file relationships.

Following is a function by function description of the Physicalc software including a representative I/O screens and descriptions of the related database files associated with the function.

The main menu for the Physicalc software program is composed of nine graphical icons 500, 501, 502, 503, 504, 505, 506, 507, & 508. By selecting the icon using a cursor pointing device (i.e. mouse) or keyboard (Tab and Enter keys), the underlying function is accessed. An associated menu bar is also available from which the user can select the function.

When the user selects the Administration icon 506, the Administrative Functions capabilities of the software are accessed. A graphical interface screen 509 is presented to the user. See FIG. 25 for screen representation.

By selecting a function presented on the screen or through selection from an associated menu bar, the user can perform one of the following tasks:

1. Examine pertinent file statistics.

2. Set the system access security for all users.

3. Chart the facility's exercise equipment usage.

4. Pack (remove deleted records) the database files.

5. Set system wide preferences.

6. Inventory DTA units.

7. Create mailing lists and labels for the clients stored in the system.

Connected to this function are two database files. The first file is called prefs.dbf 510 and is a small database file used to hold system wide preference parameters. A description of a data stored in the preference table includes the following:

1. A list of membership type categories.

2. A list of Trainer classification types.

3. The hours of operation for the facility.

4. The host PC communications port the DTA Programming Stand is connected to.

The other database file is called dta.dbf 511. This will hold the status of Digital Training Assistant units programmed by Physicalc during the current session. It is used in the Inventory DTA function in both the Administrative functions and Reports & Graphs functions of the program. A description of the records included in the database includes:

1. The client's membership number.

2. The date the DTA was uploaded.

3. The date the DTA was downloaded.

When the user selects the Configure Facility icon 505, the Facility Configuration function of the software is activated. A graphical interface screen 512 is used to input and display data records from the facility configuration database. Refer to FIG. 26 for screen representation.

This function is used to create a database of exercises and exercise equipment that are available at the facility in which the system is installed. An additional capability is the ability to create a series of template files containing a subset of exercises from the facility's master database. These templates can then be used to quickly construct exercise routines with pre-defined equipment lists.

Connected to this function are four database files. The facility configuration database file called facility.dbf 515 will contain records representing all the exercise equipment available at the facility where the Physicalc program is to be used. The user will use the Facility Exercise Configuration screen and associated menu bar to build the file's records. A complete description of an exercise includes the following:

1. Muscle Group being worked

2. Classification (free weights, nautilus machine, etc.)

3. Exercise Group (Aerobic, Anaerobic, or Stretch)

4. Exercise Name (50 characters maximum)

5. Name as Displayed by DTA (16 characters maximum)

6. Lookup Table # (if name comes from the hardcoded lookup table)

Exercises that are specified as AEROBIC will have the additional following information:

1. Up to seven (7) Mechanical settings for equipment setup (specified as a letter or number)

2. Duration (specified as either seconds, minutes, or hours)

3. Level Setting (either a letter or number)

4. Speed Setting (specified as either mph, kph, fpm, or mpm)

5. Calories Setting

6. Distance Setting (specified as either kilometers, meters, miles, or feet)

7. Incline (specified as degrees, used on treadmills)

8. Intensity Setting (target pulse rate)

Exercises that are specified as ANAEROBIC will have the additional following information:

1. Up to seven (7) Mechanical settings for equipment setup (specified as a letter or number)

2. Pounds/Plates Setting (pounds for free weights and plates for weight machines)

3. Repetitions setting

4. Sets setting (number of groups of repetitions)

5. Duration (specified as either seconds, minutes, or hours)

Exercises that are specified as STRETCH will have the additional following information:

1. Repetitions setting

2. Sets setting (number of groups of repetitions)

3. Duration (specified as either seconds, minutes, or hours)

A supplemental read-only table called lookups.dbf 516, contains a list of exercise names and associated code numbers. This table mimics the table of hard-coded exercise names found in the Digital Training Assistant (DTA) hand-held computer's firmware program. It will be used to substitute a number in place of a 16 character exercise name when programming the DTA units. This saves considerable memory space in the DTA.

As mentioned earlier, as a record is built, it may be added to Exercise Template files 514 with the unique naming convention:

xxxxxtpl.dbf (where xxxxx=first 5 characters specified by user)

The user may choose to add the current completed exercise record to a specified template table file using the Add to Template screen push button or Template.fwdarw.Add to Template menu option The end result of adding to the template is a custom list of exercises that the user can then copy to a client's workout routine as a skeleton to build upon. A Template file shares the same structure as the facility.dbf database file.

The Muscle Group Files 513 are composed of two read-only database files. The genmus.dbf database file is a read-only list of muscle groups arranged by major body part then alphabetically by major muscle group in that part of the body. The specmus.dbf database file is a read-only list of muscle groups arranged by major body part then alphabetically by specific muscle group in that part of the body

When the Client Setup icon 507 is selected, the client Information Setup function is activated. This function allows the user to input and display demographic and medical data into a client database file. Activation of the function presents the Client Information Screen 517. Refer to FIG. 27 for screen representation.

This screen is one of two used to input and display the demographic, membership and medical data elements of the selected client database. There are controls for moving around in the database as well as search, remove, and adding capabilities. Additional controls provide access to the Medical Info Screen as well as accessing the Workout Builder utility.

Connected to this screen is a single database file called client.dbf 518. This database will contain records representing demographic and medical information from a set of clients utilizing the Physicalc system. The user will use the Client Info Screen 517, Medical Info Screen 519 and associated menus to build records. A complete description of a client database record includes the following:

Each client entered into the system may have an associated fitness workout program designed for him/her. Connected to this screen are four database files. The Workout Builder function of the software is accessed from the Client Information Screen Workout push-button or menu selection. The Client Workout Profile Builder screen 520, is presented to assist the user in constructing a workout program for the currently selected client record in the client.dbf database file. Refer to FIG. 29 for screen representation.

The workout.dbf database file 521 is used as a template for creating individual Client Workout Routine 522 and Client Workout History 523 database files. In creating the individual client's workout routines, the structure from workout.dbf is copied to create the new Client Workout Routine file. A complete description of a workout routine includes the following:

1. Exercise Group (Aerobic, Anaerobic, or Stretch)

2. Machine/Exercise Mechanical Settings

3. Parametric Exercise Settings (not necessary all listed used per exercise)

a. Pounds/Plates

h. How to continue the decrease parameter philosophy

5. Routine Time Stamping

a. Start of Routine Date

b. Date of latest Completion

c. Enable Days

d. Set Number Designation

The client Workout Routine file is uniquely named using the following formula:

xxxxyyyy.dbf

xxxx: first 4-letters of th client's last name taken from the currently selected record in the Client Database file last name (last.sub.-- name) field. If the client's last name is shorter than four letters, the lower case letter `x` is appended until four letters are created.

yyyy: last 4-digits of client's membership number taken from the currently selected record in the Client Database membership number (member.sub.-- no) field. If the client's membership number is shorter than four digits, the number 9 is appended until four digits are created.

The Client Workout Routine database files 522, henceforth referred to as CWR, contains a single copy of the client's computed workout routine for the day it was requested. It will be used to create a new workout routine based upon past performance and special "philosophy" parameters entered using the Exercise Philosophy Configuration screen 524. The routine is then scheduled over a 7 day period using the Schedule Routine Screen 525.

The client may have up to 7 different workout routines designated as sets. The CWR file is grouped by set first and then sorted by exercise in the order they were input into the system.

The Client Workout History database files 523, henceforth referred to as CWH, are uniquely named using the follow formula:

xxxxyyyy.his

xxxx: first 4-letters of the client's last name taken from the currently selected record in the Client Database file last name (last name) field. If the client's last name is shorter than four letters, the lower case letter `x` is appended until four letters are created.

yyyy: last 4-digits of client's membership number taken from the currently selected record in the Client Database membership number (member.sub.-- no) field. If the client's membership number is shorter than four digits, the number 9 is appended until four digits are created.

The CWH contain a history of completed exercises. This file is composed of records representing exercises and associated performance parameters. Each record contains a date stamp allowing the Report & Graphs function to generate reports and graphs of client performance over a selected period of time. Following a workout session, the client's executed workout information data package is transferred from the DTA, modified (irrelevant fields removed, i.e. mechanical settings), date stamped, and appended to the client's CWH file. A complete description of a data stored in the records of a CWH file includes the following:

1. Full Exercise Name

2. DTA Exercise Name

3. Exercise Group (Aerobic, Anaerobic, or Stretch)

4. Parametric Exercise Settings (not necessary all listed used per exercise)

a. Pounds/Plates

b. Repetitions

c. Sets

d. Duration

e. Distance

f. Speed

g. Intensity

h. Incline

i. Calories

j. Level

5. Client's Weight

6. Client's Pulse

7. Client's Blood Pressure

8. Date of routine completion

9. Completed as Prescribed Flag

The trainer supplements an exercise's description by adding a "Philosophy" to the exercise. The Philosophy describes the action to be performed on selected exercise parameters when the client performs (or not) the exercise in the specified fashion. Pushing the Set Philosophy screen push button activates the Exercise Philosophy Configuration screen 524 where the trainer can now assign his philosophy parameters to the exercise. Refer to FIG. 30 for screen representation.

The exercise can have two of its parameters increase and two of its parameters decrease automatically. Alternatively, the exercise can choose to automatically remove itself when a specific condition is met. One action for each function is designated as the primary action and the one action is the secondary action. Both functions require a "trigger event" to occur before the increment, decrement or removal can occur. This trigger event involves checking a selected parameter against a selected value using a logical type operator. When the trigger event evaluates as "True", the primary action occurs. A limit value is included to prevent the primary action from setting a parameter too high or too low. After the trigger event occurs, it is automatically reset with the new primary action parameter value as the base.

An optional 2nd Action may also occur when the trigger event occurs. A separate check box for both the Increase and Decrease functions is provided. A second set of parameter popup lists is used to set a secondary action. The secondary action will occur every time the trigger event occurs until its own selectable limit value is reached of the primary action's limit is reached, which ever comes first.

NOTE: Program code will prevent the user from setting the primary and secondary action to the same parameter

The user specifies the parameter to be automatically modified. Next he chooses the numeric value to either add or subtract from the parameter. The user can chose a discrete value or a percentage of the current value with the % radio button. Next he selects a modification limit for the parameter. When the limit is attained, further modification is disabled. Next the trigger event is decided by selecting a different parameter or the additional options of elapsed days or completed as prescribed. Then the trigger parameter operator is selected from one of the following:

= Equal to

< Less than

<= Less than or equal to

> Greater than

>= Greater than or equal to |= Not equal to

The comparison value is set next. The trigger event will be evaluated as either True or False. A True evaluation constitutes a trigger event. The user may for either case (increase or decrease) specify a second action to be performed. Checking the Trigger 2nd Action checkbox will enable a second different parameter to be augmented. The user must again select the parameter, the increment or decrement value or percentage and the limit for the parameter.

Every time Physicalc is requested to create a client's daily workout routine, the trigger event for each exercise record in the client's CWR 522 is check against the most recent corresponding exercise record stored in the client's CWH 523 file. If the trigger conditions are determined as being met, the action parameters in the CWR 522 record is modified according to the action specification. For the initial workout, the date stored in a special field is used to determine any elapsed days.

The primary and secondary actions may also be incremented or decremented as a percentage of the current value. Selection of the % radio button will activate this feature.

A removal of an exercise as the primary action is a single shot event and once triggered, it remains disabled until explicitly set by a new philosophy setting.

Pushing the Set Schedule screen push button activates the Schedule Routine screen 525 where the trainer can now schedule exercise routines. Refer to FIG. 31 for screen representation.

Exercises can be grouped into 1 of 7 sets. This allows for the formulation of exercise set rotations found in many professional and competitive training regiments. A field in the records of the CWR database file called ex.sub.-- set designates the set it belongs to. A further enhancement of this function is the ability to schedule these sets over an arbitrary 7-day period. The period is designated as DAY #1 through DAY #7 with DAY #1 being set to a specific day of the week (stored in its own field). You can now schedule any set to any day using the Schedule Routine Screen.

The trainer simply types a number under the Day X field to designate that on that day, the exercises with the matching set number are used to formulate the daily workout routine. The software calculates the day number using the current date and the value stored in the special field.

Program code for this screen will assign a bit in a byte for each day of the week (bit 1=Day 1, etc.). When the Done screen push button is pressed, the program will look at the exercise set field of ALL records in the selected CWR database file. It will set the bit in the record's field called week.sub.-- sched corresponding to each day the exercise set was found in.

For example, an exercise record designated as belonging to Set #1 with the following Schedule Routine Screen settings will produce the resulting byte: ##STR1##

The philosophy day counting rules count total elapsed days including those not designated for the particular set. The When parameter must account for this when setting Elapsed Days.

If the user selects the Automatic Mode icon 508, the Automatic Mode function is executed. Refer to FIG. 32 for screen representation.

The Automatic Mode screen 526, is used to operate all the functions of the utility. When the client's membership card is read by the bar-code or magnetic strip reader it will present the membership number (10-digit max) to the Automatic Mode program code. The number will then be passed to the Program DTA Procedure and used to access the client's CWR 528 and CWH 527 to formulate the workout routine for the day. The workout routine is formatted into the upload exercise routine data package and transmitted to the DTA. Status of the operation is reflected in the Status field.

The user can also elect to receive data from a DTA (download). The function sends the appropriate command to the DTA to initiate downloading of its data. The data is parsed and reformatted to be incorporated back into the client's CWH file. Additional functionality allows the user to instantly perform some limited graphing functions for the client.

If the user selects the Blood Pressure icon 501, the Blood Pressure Input mode function is executed. Refer to FIG. 33 for screen representation.

The Blood Pressure Input screen 530, is used to operate all the functions of the utility. When the client's membership card is read by the bar-code or strip reader it will present the membership number (10-digit max) to the Blood Pressure Input program code. The number will then be used to access the client's CWH 531 to allow fast input of the blood pressure systolic and diastolic readings to their appropriate fields in the database's records without having to manually open the file and insert the data.

When the Trainers Setup icon 503 is selected, the Trainer Information Setup function is activated. This function allows the user to input and display demographic and employment data into the trainer database file 533. Activation of the function presents the Trainer Information Screen 532. Refer to FIG. 34 for screen representation.

This screen is used to input and display the demographic and employment data elements of the trainer database file 533. There are controls for moving around in the database as well as search, remove, and adding capabilities.

Connected to this screen is a single database file called trainer.dbf 533. This database will contain records representing demographic and employment information for a set of trainers utilizing the Physicalc system. The user will use the Trainer Info Screen 532, and associated menu to build records. A complete description of a Trainer database record includes the following:

Selecting the Reports & Graphs icon 504 will activate the Report and Graph generating function. This function will gather data elements from selected records in the DTA usage file 535, the client database riles 536, and the Client Workout History database files 537. A single main screen is used to operate the function. Refer to FIG. 35 for screen representation. Through the screen's graphical icons, the following reports and graphs can be generated:

1. Graphing a client's weight over a specified time period.

2. Graphing a client's pulse over a specified time period.

3. Graphing a client's blood pressure over a specified time period.

4. Graphing a selected exercise's parameter for a specific client over a specified time period.

5. Create mailing lists and produce mailing labels for specified clients.

6. Report a client's workout frequency.

7. Report a selected client's demographic and medical history.

8. Report on equipment usage over time by all clients.

9. Report Digital Training Assistant usage.

Selecting the Help icon 500 will bring up the on-line help utility allowing the user to access text describing the functions and operations of the system. A context type help is available using the F1 key when the cursor is in a particular field of a screen. A topical help is also available using the Help icon 500 or the Help menu option.

The user with appropriate access clearance can also modify the text of the help screens to instruct the users on club practices and procedures.

Selecting the Exit icon 502 will exit the program back to the Windows.TM. program manager.

G. Digital Training Assistant Workout Routine Program Creation Description

Central to the Physical application software are the software algorithms that create and decode exercise routine data packages. Collective they are referred to as the Program DTA procedure. Wherever necessary, the actual database file record field name is used for clarity.

The Program DTA procedure is divided into two sections. The first section involves compiling data from the Physicalc system's database files and transmitting it to a DTA (Transmit to DTA Subfunction). The second section involves the reverse process of taking data from a DTA and transferring it back into the system's database files (Receive From DTA Subfunction).

The following sections assume that the selected client's record in the currently selected Client Database file, the client's CWR, and CWH files are opened.

Transmit to DTA Subfunction

The DTA requires an upload of an exercise routine data package before use. The uploaded data consists of the exercises to be performed and the associated setup and performance parameters as determined by the trainer and the Physicalc program.

DTA Data Package Format

NOTE: All following data byte values are in their hexadecimal format as indicates by the leading 0x prefix to the number.

The DTA accepts a "data package" made up of embedded codes describing the client and the workout routine. The Program DTA Procedure will first construct the Header Block followed by the Exercise Description Blocks (EDBs) and terminated by a Footer code byte and Checksum Byte.

Header Block

The Header Block consists of 19 bytes. Any data not explicitly specified will be set to 0x0.

Header Command (Byte 1)

The header command is a byte that tells the DTA to operate in Normal Mode or Learn Mode. In Learn Mode, the DTA user can change the mechanical/ergonomic settings. In Normal Mode these changes are locked out.

Normal Mode and Learn Mode are selectable in the Workout Builder menu DTA.fwdarw.Program DTA submenu options.

Normal Mode=0x00

Learn Mode=0x02

Membership Number Bytes (Bytes 2-5)

The member.sub.-- no field of the client's client database (client.dbt) record in the currently selected client database file contains a 10-digit maximum integer number. This number is stored as four bytes in the header block with leading 0's as required. The Least Significant Byte (LSB) is stored in the Byte 2 location and the Most Significant Byte (MSB) in the Byte 5 location.

Client's Last Name Number of Characters Byte (Byte 6)

The client's last name is loaded into the DTA up to a maximum of 16 characters. The ASCII characters that makeup the last name are packed into the next 10 bytes to conserve memory in the DTA. The Number of Characters byte will tell the DTA software how many characters to extract from it's memory to display the user's last name. The number of actual characters is determined by counting characters in the last.sub.-- name field of client's record in the currently selected client database file.

Client's Packed Last Name Bytes (Bytes 7-16)

As mentioned in the above section, the ASCII characters of the client's last name are packed into 10 bytes. The ASCII value of the character is trimmed to only 5 bits, the most significant three (3) bits will be added by the DTA firmware. This, again, is done to conserve space in the limited DTA memory.

The characters are represented as the numbers 1-9 and letters A-G in the following packing diagram. In the table below, the bits of the ASCII byte representing the first letter of the client's last name (all leading and trailing blanks removed) is represented by the number 1, the second character's bits by 2, and the last by G. Bits are ordered from right to left, least significant to most significant. The program code will reformat the client's last name character string taken from the last.sub.-- name field of the client's record in the currently selected client database file.

NOTE: Any blank bytes or left over bits in the byte are set to 0

Client's Weight Bytes (Bytes 17-18)

The client's weight is stored in the CWH file's weight field. The program finds the most current record (looking at the ex.sub.-- date field) and extracts the value of the weight field in the record. If no current record found then the value defaults to 0x0000.

The field is specified as three digits and a tenths of a pound digit. The program must reformat the data as follows. If there is a tenths digit other than 0 specified (i.e. 195.8 lbs. or 97.1 lbs.) the number is multiplied by 10 to remove the fraction and stored in two (2) bytes. The MSB byte's most significant bit must then be set as a flag to notify the DTA software to divide the number by 10 before displaying.

For Example: ##STR2## Client's Pulse (Byte 19)

The client's pulse is stored in the CWH file's pulse field. The program finds the most current record (looking at the ex.sub.-- date field) and extracts the value of the pulse field in the record. If no current record found then the value defaults to 0x00. The pulse value is stored in Byte 19 of the Header Block.

Exercise Description Blocks (EDB)

Following the creation of the Header Block, the Program DTA Procedure--Transmit to DTA Subfunction will now construct EDBs incorporating Physicalc's exercise philosophy algorithms.

Exercise Philosophy Pre-Processing

The exercise routine for the specific day is extracted from the client's CWR file. Now the philosophy feature of Physicalc uses the last completed routine matching the exercise set number as derived from the processing depicted below.

The process follows a step by step procedure as follows:

1. The program first looks at the current system date and determines what day of the week it is, Monday, Tuesday, etc.

2. The program then looks at the d.sub.-- of.sub.-- week field in the first record of the CWR file. By design, all records in the CWR will have the same value in the d.sub.-- of.sub.-- week field.

3. Using the d.sub.-- of.sub.-- week value the program computes what day of the week number it is for the particular client.

4. The program will now, starting at the first record, scan through each record in the CWR and look at the record's week.sub.-- schd field byte. If a bit is set in the computed Day # bit position AND the ex.sub.-- enable field is logical True, the exercise record is copied to a temporary
