US Patent 7451728 Electronic controlled system for engines

A rotatable media storage disk creates a simulation of the rotational motion of a cam shaft which would typically provide signals to the vehicle's computer for cam shaft position and necessary requirement for valve operation. A sensor controller has been provided to work independently or in combination with an engine computer to achieve direct control of the engine valves by providing multiple data channels capable of information input, storage and output by corresponding multiple read write sensors being timed directly to the crank shaft to control a wide range of automotive engine applications.
