Abstract

The motion detection system of the present invention includes a pair of signal reflectors positioned at a defined location for directing signals into the path of travel of an object. A corresponding pair of signal detecting devices positioned on the moving object detects the signals and produces responsive electrical signals. An electrical circuit is connected to receive these electrical signals and to provide an electrical output indicative of the direction of travel of said object.
