Abstract

An interactive exercise monitor which computes and displays time, distance, pace, and energy expended by a user performing a repetitive workout around a predetermined course employs a stationary transmitter located along the workout course and a receiver carried by the user. The stationary transmitter emits a limited range signal that is detected by the receiver each time the user passes the transmitter during the workout. The receiver includes a central processing unit into which the precise distance of the course may be preprogrammed and that is then capable of computing distance accumulated by the user, elapsed time, and other desired parameters. In addition, the user may enter information such as his or her weight and a desired time, distance, and pace of the workout into the receiver.

Claims

1. An interactive exercise monitor for use by a person performing a repetitive workout around a predetermined course, the interactive exercise monitor comprising:

a single unattended transmitter fixedly positioned at a point along the course, the transmitter being operative for continuously emitting a limited range signal; and

receiver means carried by a user during a repetitive workout around said course, the receiver means being operative for detecting said limited range signal each time the user passes in proximity to said transmitter and for providing a signal to the user during each lap of said course only at the point at which the user passes in proximity to said transmitter.

2. An interactive exercise monitor as in claim 1 wherein said receiver means comprises:

microcontroller means preprogrammable with a course length and operative for computing a total workout distance as the product of the number of laps of said course traversed by the user and the course length, said microcontroller means being further operative for accumulating an elapsed workout time since the beginning of a workout by the user; and

visual display means, coupled to said microcontroller means, for selectively displaying to the user the computed total workout distance and the accumulated elapsed workout time.

3. An interactive exercise monitor as in claim 2 wherein said receiver means further comprises:

function switch means, coupled to said microcontroller means, for enabling the user to enter a desired workout time and a pace value into said receiver means;

said microcontroller means being operative for comparing said elapsed workout time to said desired workout time and for providing a signal to the user when said elapsed workout time becomes equal to said desired workout time;

said microcontroller means being further operative for computing a lap time as the result of dividing said course length by said pace value and for providing a signal to the user at time intervals equal to the computed lap time.

4. An interactive exercise monitor as in claim 3 wherein:

said function switch means is operative for enabling the user to enter a user weight into said receiver means;

said microcontroller means is further operative, following completion of a workout by the user, for computing a number of calories burned by the user during the workout; and

said visual display means is operative for displaying to the user the computed number of calories burned.

5. An interactive exercise monitor as in claim 4 wherein the number of calories burned is computed as follows:

(0.6708 * user weight+9,617) * total workout distance.

6. An interactive exercise monitor as in claim 4 wherein:

said microcontroller means is further operative, following completion of a workout by the user, for computing a final pace as the result of dividing said elapsed workout time by said total workout distance; and

said visual display means is operative for displaying to the user the computed final pace.

7. An interactive exercise monitor as in claim 6 wherein:

said function switch means is operative, following completion of a workout by the user, for enabling the user to initiate a final display mode of operation of said receiver means;

said microcontroller means is responsive to initiation of said final display mode of operation for causing said visual display means to continuously, alternately display to the user said elapsed workout time, said total workout distance, said final pace, and said number of calories burned.

8. An interactive exercise monitor as in claim 7 further comprising:

a plurality of mode indicators for indicating time, distance, pace, and calories display modes;

said microcontroller means being further operative, following initiation of said final display mode of operation, for sequentially illuminating each of said plurality of mode indicators in association with each display of said elapsed workout time, said total workout distance, said final pace, and said number of calories burned.
