Abstract:
1. In a system for monitoring a golf ball at least for a period of time following a launch of the golf ball after being hit, a method comprising: configuring an oscillator within the golf ball to oscillate at an oscillation frequency that is dependent upon a proximity of the oscillator to the Earth such that the oscillation frequency changes responsive to the ball traveling with a vertical component of movement; transmitting a radio frequency signal from said golf ball during said period of time based on the oscillation frequency; receiving said radio frequency signal from the golf ball during said period of time, exclusive of any specific position of the golf ball during said period of time, to establish one or more parameters that characterize the launch of the golf ball, based solely on the received radio frequency signal while monitoring the change in said oscillation frequency; and responsive to a predetermined change in the oscillator frequency, generating an output indication based on a vertical component of movement of the golf ball.
