Abstract: A method for predicting a golfer's swing speed, wherein the method comprises determining that the golfer is addressing a golf ball to swing a golf club, monitoring a backswing, determining a transition time, monitoring a downswing, determining an impact time, transmitting data for the golfer's swing to a receiver for analysis and generating a golfer's swing speed using a length of a shaft of the golf club.
Abstract: The method generally involves obtaining data for the golfer's typical playing characteristics using a plurality of golf clubs, determining an average end location for each of a plurality of shots taken with each of a plurality of golf clubs, and calculating the distance from the end location of each of the plurality of shots taken with each of the plurality of clubs to a target location, each distance being a putt distance.
Abstract: A circuit for transmitting a RFID signal while conserving the battery power for a circuit in continuous operation is disclosed herein. The circuit includes a RFID component, a microprocessor, an accelerometer and a battery. The battery preferably has no more than 225 milliamp hours of power. The accelerometer is preferably a multiple axis accelerometer. The circuit is preferably utilized with a device for shot tracking.
