Abstract

An integrated control system comprising an integrated circuit that controls at least one component or subsystem of an engine and a first light source that generates a first light signal when triggered through the integrated circuit. The first light signal propagates from the first light source through an LCC that may also serve as a substrate, wherein the signal that actuates the component of the engine can be the first light signal or a signal generated after the first light signal is produced. The component or subsystem of the engine may be an ignition system or a fuel injection system. The present invention is also directed to a method of controlling a component or subsystem of an engine.
