Abstract
A device for measuring the movement of a ball is a flat pad or a frame defining an opening with one or more magnetic field inducing elements mounted thereon. One or more sensor elements are mounted in the flat pad or the frame, and connected to instrumentation so as to record induced, time-varying current signals from disturbances in a magnetic field by the ball penetrating the field. The device may also be arranged so as to measure the spin characteristics and other vectors of a conductive, charged and/or magnetized golf ball penetrating field. Or, the device may be arranged so as to have no magnetic field inducing elements, whereby the magnetic field of a modified, magnetized golf ball, when passing through an opening, or over a flat pad, induces time varying current signals in at least one sensor element, which can be processed to predict the complete ball flight parameters, i.e., velocity, trajectory and spin.
