Abstract: A valve actuator assembly for an engine includes a movable engine valve, a movable first spool valve, and a movable second spool valve. The valve actuator assembly also includes an intermediate channel interconnecting the first spool valve and the second spool valve, and a driving channel, a first feedback channel, and a second feedback channel interconnecting the second spool valve and the engine valve. The valve actuator assembly includes an actuator operatively cooperating with the first spool valve to position the first spool valve to prevent and allow high pressure fluid flow to the second spool valve and the driving channel to position the engine valve.

Abstract: A parallel flash programming system for use in motor vehicle assembly includes an input receptive of information relating to a predetermined number of processors connected to a system bus, processor flash programming attributes, and system bus attributes. An incremental flash programming times determination module is adapted, based on the information, to determine incremental flash programming times of a processor in relation to multiple interframe wait times respective of multiple parallel flash programming schema in accordance with the predetermined number of processors. A global flash programming time resolution module is adapted to determine, based on incremental flash programming times respective of multiple processors of the predetermined number, an assignment of the multiple processors to a number of parallel programming tracks yielding a global flash programming time in accordance with predetermined criteria.
