Abstract

The device of the present invention, positionable in or on a golf bag, monitors golf club location or presence. The device includes a marker mechanism, or tag, positionable on a golf club that imparts a unique identification to the club. The device also includes a sensing mechanism or sensing system that monitors the status of the clubs, including the presence, removal and return of the golf clubs. As each club includes a unique identifier, the sensing system can track the clubs by monitoring the sensors. The device also includes a readout mechanism that cooperates with the sensing system to provide information to the golfer regarding the status of their clubs.

Claims

1. A detection system for determining the presence or absence of a plurality of golf clubs in a golf bag, comprising:

a plurality of transponders associated with the plurality of golf clubs; and

an interrogation system for generating an interrogation signal adapted to interact with the plurality of transponders, such that each of the plurality of transponders will produce a distinct return signal, the interrogation system for further sensing the distinct return signal produced by each of the transponders and producing an indication of the presence or absence of the plurality of golf clubs.

2. The detection system of claim 1 wherein the interrogation system includes a transmitter for producing and transmitting the interrogation signal and a receiver for receiving the distinct return signals.

3. The detection system of claim 2 wherein the interrogation system includes a processor in communication with the transmitter and a receiver output, the processor for interpreting the distinct return signals and producing an inventory output indicative of the presence or absence of clubs in the golf bag.

4. The detection system of claim 3 wherein the interrogation system further comprises a readout coupled to the processor for producing an advisory signal to a golfer in response to an indication that one of the plurality of golf clubs is missing.

5. The detection system of claim 4 wherein the advisory signal is a visual signal.

6. The detection system of claim 4 wherein the advisory signal is an audible signal.

7. The detection system of claim 4 wherein the advisory signal is a physical vibration.

8. The detection system of claim 1 wherein the interrogation signal is a radio frequency signal of a predetermined frequency.

9. The detection system of claim 8 wherein each distinct return signal is at a second predetermined frequency with a predetermined time delay.

10. The detection system of claim 8 wherein each distinct return signal is at a predetermined return frequency.

11. The detection system of claim 10 wherein each distinct return signal further includes a predetermined time delay.

12. The detection system of claim 1 wherein the interrogation signal is a radio frequency signal which includes a plurality of frequency components.

13. The detection system of claim 12 wherein the interrogation signal includes a timed sequence of signal segments, each signal segment consisting of one of the plurality of frequency components.

14. The detection system of claim 13 wherein each of the plurality of transponders is responsive to one of the plurality of frequency components.

15. A golf club inventory system for monitoring the presence or absence of a golf club in a golf bag having a detector attached thereto, the inventory system comprising:

a transponder associated with the golf club for producing a unique identification signal in response to an interrogation signal produced by the detector;

a detection system for sensing the unique identification signal and producing an indication of the presence or absence of the golf club, the detection system including a transmitter/receiver for producing the interrogation signal and for detecting the unique identification signal, the detection system further including a processor coupled to the transmitter/receiver for interpreting the received unique identification signals and producing an output indicating the presence or absence of the golf club.

16. The detection system of claim 15 wherein the unique identification signal is an RF signal produced in response to the receipt of the interrogation signal produced by the detection system.

17. The detection system of claim 15 wherein the interrogation signal is a radio frequency signal of a predetermined frequency.

18. The detection system of claim 15 wherein the interrogation signal is a radio frequency signal which includes a plurality of frequency components, and wherein the identification signal is produced in response to one of the frequency components.

19. The detection system of claim 18 wherein the interrogation signal includes a plurality of sequential segments, each segment consisting of a timed signal of one of the plurality of frequency components.

20. The detection system of claim 18 wherein each of the plurality of transponders is responsive to one of the plurality of frequency components.

21. The detection system of claim 15 wherein each unique identification signal is at a second predetermined frequency with a predetermined time delay.

22. The detection system of claim 15 wherein each unique identification signal is at a predetermined return frequency.

23. The detection system of claim 22 wherein each unique identification signal further includes a predetermined time delay.
