Abstract: An electronic engine controller includes a central processing unit (CPU) which controls the operations of the controller and an analog-to-digital (A/D)converter chip which receives analog signals generated by sensors which transmit signals indicative of vehicle and engine operating parameters. The A/D converter chip automatically performs a conversion on certain signals indicative of critical engine operating parameters to generate corresponding digital values upon each engine revolution. These digital values are stored for retrieval by the CPU. Digital values corresponding to other signals are generated and transmitted upon request by the CPU. The A/D converter chip and the CPU are coupled by a serial link which operates under one of several protocols to transmit digital values from the A/D converter chip to the CPU.

Abstract: An automotive door assembly comprising a rigid frame structure defining the main body of the door assembly, an outer skin fixed to an outer side of the rigid frame structure defining the exterior appearance of the door assembly, and a panel assembly disposed on the opposite side of the rigid frame structure defining the interior appearance of the door assembly. A plurality of electrically operated components are carried by the rigid frame structure having first current connectors mounted in generally stationary relation on the rigid frame structure in oppositely facing and oppositely accessible relation with respect to the outer skin. An electrical harness assembly forming a part of the panel assembly includes second current connectors mounted in generally stationary relation on the panel assembly in oppositely facing and oppositely accessible relation with respect to the appearance defining surface thereof.
