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.

Claims

1. Apparatus for controlling the raising and lowering of a motor vehicle window, comprising:

signal generating means for providing a single, manually-activated signal, remote from a vehicle,

transmitting means located with said signal generating means for communicating said manually activated signal to a vehicle without the use of a physical connection between said signal generating means and said vehicle;

receiving means located in said vehicle for receiving said manually activated signal;

window controlling means responsive to said receiving means for activating a window motor in said vehicle in response to said manually-generated signal to raise or lower a window located in said vehicle, said window control means including a flip flop having an up driver output and a down driver output, an up driver circuit connected to said up driver output of said flip flop and a down driver circuit connected to said down driver output of said flip flop, and termination means for breaking the connection between said flip flop and said up driver circuit with termination of said manually-activated signal.

2. Apparatus according to claim 1 wherein said window controlling means further includes a timing means between said flip flop and said down driver circuit for providing a signal of predetermined duration to said down driver circuit upon activation of the down driver output of said flip flop.

4. Apparatus according to claim 1 wherein said down driver circuit includes an electro-mechanical relay having a coil, and a transistor directing input power to said coil, said transistor being normally closed, the base of said transistor being connected to the input of said up driver circuit.

3. Apparatus according to claim 9 wherein said window controlling means further includes a second termination means for terminating said timing means signal upon activation of said up driver output of said flip flop.
