ABSTRACT:
Apparatus is provided by which a motor vehicle window can be raised and lowered remotely by the use of a unique circuit which interfaces with the motor provided in the vehicle for such purposes. A hand-held transducer, utilizing either radio frequency energy or ultrasonic energy, is used to provide a momentary signal which activates the circuitry, configured to respond to a first signal by causing the window to be completely lowered. Transmission of a second identical signal will begin to raise the window and will continue to do so only as long as the signal remains activated.
