ABSTRACT:
Within a bat handle a resiliently mounted magnet oscillates when the bat strikes a ball. The magnetic field couples with a fixed inductive coil inducing a signal with an amplitude proportional to the impact force. The signal is processed to provide an indication on the bat of the force of impact.
