Abstract:
A system and method for shot tracking is disclosed herein. The system preferably includes a golf club, a receiver device and a server with a website. The golf club preferably includes an active RFID transponder, a power source and a shock switch. When the golf club strikes a golf ball, the shock switch closes thereby powering the RFID transponder which sends a signal to the receiver device for automatically tracking a golfer&#39;s round of golf. The data is then uploaded to the website for processing.

     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     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. 
     2. Description of the Related Art 
     Golf clubs combine with the players swing to propel a ball toward a favored location and through a favored path. The orientation and speed of the club head at impact largely determines the ball path including carry distance and roll. 
     Various data measuring and collecting devices and methods are used for analyzing a golf club during a golf swing. In a similar manner, the effectiveness of a golf ball impact with the golf club during the golf swing can be measured in terms of initial launch conditions. Such launch conditions include the initial velocity, launch angle, spin rate and spin axis of the golf ball. These launch conditions are determined principally by the velocity of a club head at impact and the loft and angle of a club face relative to the intended trajectory of the golf ball&#39;s flight. There are two general methods for analyzing the golf club during a golf swing: visual analysis and quantitative variable analysis. 
     The method of analyzing a golf club during a golf swing using visual analysis typically is conducted by a golf instructor capable of visually discerning golf swing variables, and suggesting corrections in the golfer&#39;s swing to provide improvement. However, not every golfer has ready access to professional golf instruction. The golfer also can diagnose certain swing faults using visual analysis methodology employing one or more cameras to record the golfer&#39;s swing and comparing it to a model swing. Using various camera angles and slow motion play back, the actual swing motion can be reviewed and altered in subsequent swings. 
     On the other hand, quantitative variable analysis employs sensors to directly measure various mechanical or physical properties of the golf club during the swing motion. Sensors, such as strain gauges or accelerometers, typically are attached to the shaft or the golf club head. Data collected from these strain gauges then may be transferred to a signal processor via wires or radio waves, and can be presented in various graphical formats, including graphical and tabular charts. A significant drawback associated with the use of wires in an instrumented golf club is that the wires can be very cumbersome, and can become obtrusive to the golfer when the golfer attempts to swing the golf club. Several different approaches to analyzing a golf club or baseball bat during a baseball or golf swing using quantitative variable analysis are discussed in the patents listed below. 
     U.S. Pat. No. 4,759,219, issued to Cobb et al., the specification discloses a baseball bat with a self-contained measuring device and display. A spring potentiometer is used to measure centrifugal force, and an LED or LCD displays the measured force. However, this bat does not contain any data storage capability. 
     U.S. Pat. No. 5,233,544, issued to Kobayashi, discloses a golf club having multiple sensors, and a cable for transmitting data to a computer for data processing. This arrangement can accommodate up to 5 sensors in a cartridge located in the handle region of the golf club. 
     U.S. Pat. No. 3,182,508, issued to Varju, discloses the use of a strain gauge in the bottom of a golf club, and a wire for connecting the sensor to a data processing means located separate from the golf club. 
     U.S. Pat. No. 5,694,340, issued to Kim, discloses the use of multiple sensors for measuring the acceleration of a golf club, and uses either a cable or radio transmissions to transfer data from the sensors to an external data processing means. 
     U.S. Pat. No. 4,991,850, issued to Wilhelm, discloses the use of a sensor for measuring the applied force of a golf swing. The sensor data can be displayed on a wrist-mounted arrangement or be downloaded to a computer via cable or radio transmission. 
     U.S. Pat. No. 3,792,863, issued to Evans, discloses the use of multiple sensors, including an accelerometer and strain gauges, to measure torque and flex. Data is transferred from the golf club to a data analysis station via FM radio signals, with each sensor having its own data transfer frequency. 
     The prior art is lacking in a method and system for shot tracking. 
     BRIEF SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in  FIG. 1 , components of the system can be attached to a golf club. Alternatively, the components can be integrated into a golf club. Greater details on shot tracking are set forth in U.S. Pat. Nos. 7,801,575, 7,800,480, 7,804,404, 7,831,212, 7,847,693, 7,853,211, 7,883,427, 7,883,428, 7,899,408, 7,911,186, 7,915,865, 7,927,225, 7,941,097, 7,946,926 and 8142302, all of which are hereby incorporated by reference in their entireties. 
     Different levels of acceleration switches can be effectively used to detect that a golf club has been used by a golfer. A 50 g switch, a 125 g switch and a 500 g switch were used for testing. 
       FIG. 3  illustrates a portion of a golf club  50 . The components of the system  20  within the golf club  50  preferably include an active RFID transponder  51 , a power source  52 , a switch  53  and an accelerometer  54 . Those skilled in the pertinent art will recognize that the accelerometer and switch may be a single device. 
     A method  1000  for shot tracking begins with a golfer swinging a club and impacts a golf ball. Diagnostics and an accelerometer are activated by the swing and impact of the golf club with the golf ball. The diagnostics of the golf club measure at least golf club speed. A switch located between a power source and an active RFID transponder is temporarily closed due to the activation of the accelerometer. The active RFID transponder is powered by the power source. The active RFID transponder transmits at least one signal containing data about the golf club which includes the type of club and the club speed. The signal is received at a receiver device. The signal is then stored at the receiver or transmitted to another device. 
       FIG. 5  illustrates the system  20 . A transponder in a golf club  50  swung by a golfer sends a signal  62  to a receiver device  60 . A wrist worn golf GPS device  60  is capable of wireless transmission using BLUETOOTH communications or a similar communication protocol. The wrist worn golf GPS device  60  may also be capable of storing the data for later transmission. The wrist worn golf GPS device  60  is preferably a GPS device with GPS functions such as disclosed in Balardeta et al., U.S. Patent Publication Number 20090075761 for a Golf GPS Device And System, which is hereby incorporated by reference in its entirety.
