Abstract:
An acceleration monitor assembly for measuring acceleration forces on a first golf club head during the swing of a first golf club comprising:a circuit board having; at least one power supply battery mounted on said circuit board; a linear accelerometer for measuring centripetal force, having a first accelerometer axis, mounted on said circuit board, with the first accelerometer axis parallel to a circuit board axis, and connected to the at least one power supply battery; an accelerometer calibrator, for accommodating changes in the radius of a path of movement of the linear accelerometer, mounted on said circuit board and connected to the linear accelerometer and the at least one power supply battery; said circuit board releasably mounted on a shaft of the first golf club between a center of the shaft and the first golf club head with the first accelerometer axis and the circuit board axis parallel to a club shaft axis, and releasable from the shaft of the first golf club for transfer to a second golf club; a wireless transmitter mounted on said circuit board with the linear accelerometer and connected to the linear accelerometer to receive signals generated by the first linear accelerometer and transmit the signals through an antenna connected to the wireless transmitter; and a wireless receiver spaced from said circuit board and the shaft upon which said circuit board is mounted and wherein the wireless receiver receives the signals from the wireless transmitter.
