Abstract

The present invention relates to shot tracking. More specifically, the present invention relates to a method and system for tracking shots of a golfer during a round of golf. One aspect of the present invention is a system for automatically tracking a golf club swung by a golfer. The system comprises a plurality of golf clubs. Each of the plurality of golf clubs comprises a device attached to a grip which is attached to a shaft which is attached to a golf club head. The device comprises a power source, a shock switch and a RFID component.

Claims (18)

1. A system for tracking a golfer's shot during a round of golfer, the system comprising:

a receiver;

a plurality of devices, each of the plurality of devices positioned within a grip of a golf club of a set of golf clubs, each of the plurality of devices comprising

a microprocessor positioned within the housing, the microprocessor in electrical communication with the battery,

a resistor,

a capacitor,

a shock switch

a radiofrequency component positioned within the housing, the radiofrequency component in electrical communication with the microprocessor, the radiofrequency component transmitting a signal;

wherein the device has a 2 milliamps limit for transmission of the signal, wherein after impact with a golf ball, the shock switch is closed allowing power to flow from the capacitor to the radiofrequency component for transmission of the signal, and wherein the resistor minimizes an electrical current flow to the capacitor to allow the capacitor to be charged at a controlled rate from the battery.

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

3. The system according to claim 1 wherein the golf clubs in the set comprises woods, irons and a putter.

4. The system according to claim 1 wherein the receiver is one of a personal digital assistant, a smart phone or mobile phone.

5. The system according to claim 1 wherein the battery of each device of the plurality of devices is a 3-volts battery.

6. The system according to claim 1 wherein the capacitor of each device of the plurality of devices is a 1 microFarad capacitor.

7. The system according to claim 1 wherein the radiofrequency component of each device of the plurality of devices is a 2.4 gigaHertz transceiver.

8. The system according to claim 1 wherein the microprocessor of each device of the plurality of devices is configured to deactivate transmissions of the signal from the radiofrequency component when a threshold number of signals are transmitted by the device and a receipt signal is not received by the device.

9. The system according to claim 8 wherein the threshold number of signals ranges from 5 to 50.

10. The system according to claim 1 wherein the shock switch of each device of the plurality of devices is a single channel slew rate controlled load switch.
