Abstract

A system and method for shot tracking disclosed herein. The system preferably includes a golf club and a receiver. The golf club preferably includes an active RFID transponder, a power source, a switch and an accelerometer.

Claims

1. A system for automatically tracking a golf club swung by a golfer, the system comprising:

a golf club comprising a shaft and a golf club head, the golf club having a an accelerometer in electrical communication with an active RFID transponder, the accelerometer temporarily closing a switch during impact with a golf ball to provide power from a power source to the RFID transponder for transmission of a signal, the signal containing data for the specific golf club;

a receiver for receiving the signal from the RFID transponder.

2. The system according to claim 1 wherein the receiver is a GPS unit.

3. The system according to claim 1 wherein the receiver stores data for each shot by the golfer for a round of golf.

4. The system according to claim 1 wherein the data of the signal comprises type of club and force of the shot.

5. The system according to claim 1 wherein the type of club is selected from wedge, 9-iron, 8-iron, 7-iron, 6-iron, 5-iron, 4-iron, 3-iron, 2-iron, 9-wood, 7-wood, 5-wood, 3-wood, driver, putter, 1-hybird, 2-hybrid, 3-hybrid, 4-hybrid, 5-hybrid and 6-hybrid.

6. The system according to claim 1 wherein the accelerometer is a 50 G accelerometer.

7. The system according to claim 1 wherein the accelerometer, the active RFID transponder, the switch and the power source are located within the shaft of the golf club.

8. The system according to claim 1 wherein the accelerometer, the active RFID transponder, the switch and the power source are located within the golf club head of the golf club.

9. The system according to claim 1 wherein the accelerometer, the active RFID transponder, the switch and the power source are located are the exterior of the shaft of the golf club.

10. A method for shot tracking, the method comprising:

impacting a golf ball with a golf club;

activating an accelerometer positioned on the golf club;

closing a switch for a set time period, the switch positioned between a power source and an active RFID transponder;

powering the active RFID transponder with power from the power source;

transmitting a signal from the active RFID transponder, the signal comprising golf club data; and

receiving the signal at a receiver.

11. The method according to claim 10 wherein the receiver is a GPS unit.

12. The method according to claim 10 wherein the receiver stores data for each shot by the golfer for a round of golf.

13. The method according to claim 10 wherein the data of the signal comprises type of club and force of the shot.

14. The method according to claim 10 wherein the type of club is selected from wedge, 9-iron, 8-iron, 7-iron, 6-iron, 5-iron, 4-iron, 3-iron, 2-iron, 9-wood, 7-wood, 5-wood, 3-wood, driver, putter, 1-hybird, 2-hybrid, 3-hybrid, 4-hybrid, 5-hybrid and 6-hybrid.

15. The method according to claim 10 wherein the accelerometer is a 500 G accelerometer.

16. The method according to claim 10 wherein the accelerometer, the active RFID transponder, the switch and the power source are located within the shaft of the golf club.

17. The method according to claim 10 wherein the accelerometer, the active RFID transponder, the switch and the power source are located within the golf club head of the golf club.

18. The method according to claim 10 wherein the accelerometer, the active RFID transponder, the switch and the power source are located are the exterior of the shaft of the golf club.

19. The method according to claim 10 further comprising storing the data at the receiver.

20. A system for automatically tracking a golf club swung by a golfer, the system comprising:

a golf club comprising a shaft and a golf club head, the golf club having a an accelerometer switch in electrical communication with an active RFID transponder, the accelerometer switch temporarily closing during impact with a golf ball to provide power from a power source to the RFID transponder for transmission of a signal, the signal containing data for the specific golf club;

a receiver for receiving the signal from the RFID transponder.
