Abstract: A cam follower assembly for use in a latching switch assembly comprises a case having opposed walls with a slot in one of the walls. A cam follower disposed in the case has a post movable within the slot. A spring adjacent the cam follower biases the cam follower toward a longitudinal axis of the case. The cam follower assembly cooperates with a cam in the latching switch assembly to operate an electrical switch. In a preferred embodiment, the cam follower assembly moves in a plane parallel to the plane of the cam surface. When an operator depresses the latching switching in the latching switch assembly, the cam follower rides along the cam to an "on" position where the latching switch is held in place. Upon depressing the latching switch once more, the cam follower moves out of the first position and into its original "off" position. The slot guides the cam follower for proper desired movement. The spring is preferably a C-shaped spring with two arms positioned on each side of the cam follower.

Abstract: A watchdog circuit and method are provided for monitoring a microprocessor to detect the presence of a malfunction condition such as a program lock-up. The watchdog circuit includes a first capacitor coupled to a supply voltage and a transistor having a collector and emitter coupled in parallel with the first capacitor. The transistor has a base for receiving a signal in response to a status output signal generated by the microprocessor.

Abstract: A family of retainer clip holders can each be adjusted to properly position a retainer clip at a desired location on a wire harness. In the past, it has sometimes been complicated to properly position a retainer clip holder relative to the base, and mount the holder base on a jig for assembling wire harnesses. There have typically been too many fixtures required on the jig. Thus, the prior art has attempted to assemble the retainer clips by individually tailoring hundreds of retainer clip holders for the particular orientation demanded by the particular retainer clip application. The inventive family of retainer clip holders allows the selection of the proper adjustable retainer clip holder and the adjustment of that retainer clip holder to accommodate the particular retainer clip application demanded. In this way, the invention replaces the hundreds of previously required holders with seven basic tools.

Abstract: Loads, such as power relays controlling wipers, windows and lights are connected to an automobile battery through individual transistor drives that are controlled by a microcontroller. A switch, connected to the microcontroller, is operated to activate each drive. The microcontroller checks the load characteristic when each drive is activated and inactivated. When the load is inactivated, it is part of a resistance network producing a test voltage that is digitally converted and supplied to the microcontroller, which compares the test voltage to a stored voltage to determine if the load is correct. An analog multiplexer is controlled by the microcontroller to select the voltage produced for each load.
