ABSTRACT:
This invention is concerned with a remote control trans-receiver system in which a transmitter having a single channel is used for transmitting information to a remote receiver adapted to receive the information for controlling the movements of a toy vehicle. The single transmitting channel includes means to provide modulated information onto a carrier wave for controlling the forward, rightward and leftward movements of the toy vehicle, and a switching device for preventing the transmission to the receiver of any modulating information to permit stopping of the forward movement of the vehicle and to enable, when desired, reverse movement of the toy vehicle. The receiver detects the modulated information, when present, for effecting forward, rightward or leftward movement of the toy vehicle. The receiver further includes a switching device which responds to the absence of a modulating signal on the carrier to stop and then reverse the direction of travel of the toy vehicle.
