ABSTRACT:
A garage parking position indicator operable on principles of wave energy. A wave energy detector such as an infrared receiver is mounted to one side of the garage access door at a point displaced from the rear wall of the garage by a distance greater than the length of the vehicle. A wave energy source, such as an infrared transmitter, is mounted on the opposite side of the garage access door from the receiver. The transmitter and the receiver are mounted at a height suitable for cross-secting the traveling vehicle from his leading edge to its trailing edge, preferably from bumper to bumper. The transmitter constantly transmits and directs wave energy toward the receiving means so that the presence of any portion of the vehicle between the transmitter and the receiver will interrupt reception of the wave energy by the receiver.
