Method and apparatus for periodically checking the ground path resistance value of a crash sensor connection to chassis ground and determining if the resistance exceeds a predetermined maximum acceptable value.

Ground connection monitoring for airbag electrical igniter circuit

Method and apparatus for periodically checking the critical resistance value of an airbag igniter ('squib') component and determining if the resistance exceeds a predetermined maximum value.

Airbag electrical igniter readiness detector

A control circuit for a reversible D.C. window drive motor that allows for one touch operations of the motor to automatically lower the associated window to its full down position following a relatively short actuation of the control switch in the 'DOWN' position. Subsequent actuation and release of the control switch will cause interruption and inhibit the automatic lowering of the window. Longer actuations of the control switch allows for direct movement control of the window in the downward direction. Stall current sensing and excessive time sensing provide protection to the motor and the drive circuitry.
