a third switch electrically connected to said power source and providing a third predetermined signal when the openable body panel is open;
a first electrical circuit adapted to read said first, second and third signal, and determining if said first, second, and third signals are present or absent, and if said signals are all absent, sending a fourth signal to close said window;
said window having a fourth switch sending a fifth signal when the window is open;
said fourth switch being electrically connected to a second circuit adapted to receive said fourth and fifth signals and if both signals are present, to send a sixth signal to energize a motor to close said window;
a first X-OR GATE having a first input electrically connected to said first switch and a second input electrically connected to said power source so that a first output signal is produced when said seat is occupied;
a second X-OR GATE having a first input electrically connected to said second switch and a second input electrically connected to said power source so that a second output signal is produced when said openable body panel is open;
a third X-OR GATE having a first input electrically connected to said third switch and a second input electrically connected to said power source so that a third output signal is produced when key is in said ignition; and
an AND GATE having a first AND GATE input for receiving said first output signal, a second AND GATE input for receiving said second output signal and a third AND GATE input for receiving said third output signal, said AND GATE generating said fourth signal when all of said inputs are present.

Abstract
A control circuit for controlling a vehicle window closing and door locking device, comprises a first circuit having three X-OR gates and one AND gate for determining the vehicle general conditions, a second circuit having AND gates and power transistors for determining the vehicle specific conditions, for energizing the individual window motors, and for activating the door lock solenoid. The windows will be closed and the doors will be locked if three conditions are met: (1) no one is seated inside the vehicle, (2) all doors are closed, and (3) the ignition key is not in the ignition.
