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.
The prior art is lacking in a method and system to measure the motion of the club through measurement of the shaft.
The present invention is novel in that the observation of the relative motion does not depend on near visible light and uses a coherent pattern to capture the position of the club relative the ground antenna transmitter/receiver. This fixed device also includes a display, computing capability and recording device. This information, when processed, enables the display of the swing and uses data on the club head and ball to calculate the flight of the ball.
This invention is a shot tracking device for attachment to a grip of a golf club. The shot tracking device comprises a housing, a battery disposed within the housing and a circuit board disposed within the housing. In one embodiment, the housing may comprise a main body and a projection body extending downward from the main body. The circuit board has a first side and a second side. A sensor is disposed on the circuit board and a plurality of board components are disposed on the first side and the second side of the circuit board. The plurality of board components includes a microprocessor. The shot tracking device transmits a signal when the golf club strikes an object. The signal comprises the identification of the golf club. The microprocessor is configured to deactivate transmissions of the signal when a threshold number of signals are transmitted by the shot tracking device and a receipt signal is not received by the shot tracking device. The threshold number of signals ranges from 5 to 50.
The present invention further comprises a method for conserving power for a shot tracking device for attachment to a golf club. The method involves transmitting a plurality of signals from a shot tracking device attached to a golf club. The shot tracking device comprises a housing, a battery disposed within the housing, a sensor, and a plurality of board components disposed on a circuit board, the plurality of board components including a microprocessor. The shot tracking device is enabled to determine that a threshold number of signals has been transmitted by the shot tracking device and a receipt signal has not been received by the shot tracking device, which in turn deactivates the shot tracking device until a predetermined event occurs. The threshold number of signals ranges from 5 to 50.
