Abstract: An electronic athletic instrument which measures the differences in time in which shock waves (or vibrations), caused by a movable game element hitting the instrument, are detected by different sensors, located on the periphery of the surface. By means of predetermined open window time periods and possible delays, as well as effecting different dimensional zones, this instrument is able to provide for instructive feedbacks to different players with different skill levels.
Abstract: A tennis racquet or other athletic instrument configured for striking a moveable ball or other playing element includes electronic sensors for providing an audible or audio-visual indication of the location on the racquet or instrument at which contact is made with the ball or other playing element. Various devices for sensing the location of contact are disclosed.
