Abstract

A method and apparatus for monitoring the movement of an object traversing a circuit and outputting data with respect thereto. Lap events are recorded and used to calculate a total lap count, split time, and elapsed time for an event that includes the repetitive traversing of a circuit. Physiologic data is monitored in the case where the object is a person. A transponder or transmitter is affixed to a user and a signal having limited range is coupled to a communications and display device when the user comes into range of the device. Each such coupling is accumulated as lap event data. Calculations are made to display the lap count and timing information as well as physiologic data. In one embodiment, the device is implemented in a watertight housing and placed at the bottom of a swimming pool. The displayed information is visible to a swimmer wearing the transponder or transmitter. In another embodiment, the display is incorporated into eyewear worn by the person traversing a repetitive circuit.

Claims

1. A system for monitoring the movement of an object traversing a circuit and outputting data with respect thereto, said system comprising:

a first wireless communications device affixed to the object;

a second wireless communications device operable to communicate with said first communications device when located within a predetermined proximity thereto;

a controller operatively coupled to said first or said second communications device and adapted to monitor communications therebetween, and accumulate data therefrom; and

an output device coupled to receive data from said controller, wherein the presence of said first communications device within said predetermined proximity of said second communications device for a period of time greater than a threshold duration causes said controller to start an elapsed time interval timer when said first communications device moves beyond said predetermined proximity of said second communications device.

2. The apparatus of claim 1 wherein said data is a lap count, a split time or an elapsed time.

3. The apparatus of claim 2 further comprising a user input coupled to said controller and wherein activation of said user input causes said controller to reset said lap count and initialize a starting sequence.

4. The apparatus of claim 3 wherein said controller is operable to execute a count down timer before initializing said starting sequence.

5. The apparatus of claim 1 wherein the object is a person or a swimmer.

6. The apparatus of claim 1 wherein said first communications device and said second communications device are enclosed in waterproof housings.

7. The apparatus of claim 1 wherein said output device is a visual display.

8. The apparatus of claim 7 further comprising a means for activating said display while said communications devices are located within said predetermined proximity of one another.

9. The apparatus of claim 1 further comprising an input/output interface coupled to said controller, said input/output interface operable to communicate said data to an external device.

10. The apparatus of claim 1 wherein said first communications device is operable to communicate unique identification codes as a part of said data.

11. The apparatus of claim 10 wherein said controller is operable to decode a plurality of said unique identification codes and operable to accumulate a plurality of data sets corresponding thereto.

12. The apparatus of claim 1 wherein said first communications device is a transponder and said second communications device is a transceiver, and wherein said controller is coupled to and co-located with said transceiver and said output device.

13. The apparatus in claim 12 wherein said transceiver is adapted to interrogate said transponder.

14. The apparatus of claim 1 further comprising:

a physiologic sensor coupled to said first communications device and is operable to communicate physiologic data there through, and wherein

said controller is coupled to and co-located with said second communications device and said output device, and said controller is operable to receive said physiologic data that has been communicated by wireless communications, and wherein said controller outputs processed physiologic data to said output device.

15. The apparatus of claim 14 wherein said physiologic data is heart rate or blood-oxygen level data.

16. The apparatus of claim 14 wherein said physiologic sensor is a finger cot sensor.

17. The apparatus of claim 14 wherein said output device is a visual display incorporated into an item of eyewear.

18. The apparatus of claim 17 wherein the object is a person swimming in a water circuit, and said eyewear is swimmer'"'"'s goggles.

19. The apparatus of claim 1 further comprising:

a physiologic sensor coupled to said controller, and wherein

said second communications device is a transponder and said first communications device is a transceiver adapted to interrogate said transponder, and wherein

said controller is coupled to and co-located with said first communications device and said output device, and wherein

said controller receives physiologic data from said physiologic sensor and outputs processed physiologic data to said output device.

20. The apparatus of claim 19 wherein said physiologic data is heart rate or blood-oxygen level data.

21. The apparatus of claim 19 wherein said physiologic sensor is a finger cot sensor.

22. The apparatus of claim 19 wherein said output device is a visual display incorporated into an item of eyewear.

23. The apparatus of claim 22 wherein the object is a person swimming in a water circuit, and said eyewear is swimmer'"'"'s goggles.

24. A method of accumulating and outputting data related to an object traversing a circuit wherein a first wireless communications device is affixed to the object and a second wireless communications device is fixed and operable to communicate with the first communications device when located within a predetermined proximity thereto, comprising the steps of:

determining the presence of the first communications device within the predetermined proximity by establishment of a wireless communications link with the second communications device;

communicating an identification signal to identify the first communications device;

starting an elapsed time interval timer when the first communications device is within the predetermined proximity of the second communications device for a period of time greater than a threshold duration and then moves beyond the predetermined proximity;

accumulating successive identification signals as lap interval data; and

outputting said lap interval data to the output device.

25. The method of claim 24 wherein said lap interval data is a lap count, a split time or an elapsed time.

26. The method of claim 25 further comprising the step of activating a user input to reset said lap count thereby initializing a starting sequence.

27. The method of claim 26 further comprising the step of executing a count down timer before initializing said starting sequence.

28. The method of claim 24 wherein the object is a person or a swimmer.

29. The method of claim 24 wherein said first communications device and said second communications device are enclosed in waterproof housings.

30. The method of claim 24 wherein said output device is a visual display.

31. The method of claim 24 further comprising the step of activating the display while the communications devices are located within said predetermined proximity of one another.
