Abstract: Disclosed is a method for forming a heat sink laminate and a heat sink laminate formed by the method. In the method a particle mixture is formed from a metal, an alloy or mixtures thereof with a ceramic or mixture of ceramics. The mixture is kinetically sprayed onto a first side of a dielectric material to form a metal matrix composite layer. The second side of the dielectric material is thermally coupled to a heat sink baseplate, thereby forming the heat sink laminate.

Abstract: The invention is a suspension system, typically for use between a cab and a truck frame, includes a strut module having a strut and an air spring, and a control module, connected to a source of pressurized air, for sensing a distance between the cab and truck frame and selectively pressurizing the air spring in response to changes in that distance. Preferably, the strut is a McPherson-type strut and the air spring encloses at least a portion of the strut to provide a compact assembly and includes a three point connection to the cab and frame to resist relative lateral movement between the cab and frame. The strut also preferably is a magnetorheological-type damper so that the control module can adjust the damping characteristics of the strut to optimize rider comfort.

Abstract: A non-thermal plasma reactor is provided. The non-thermal plasma reactor includes a plasma-generating substrate, a housing and a mat. The plasma-generating substrate has one or more flow paths for an exhaust gas. The housing has an inlet and an outlet. The mat retains the plasma-generating substrate in the housing such that the one or more flow paths are in fluid communication with the inlet and the outlet. A voltage is supplied to the plasma-generating substrate to generate a plasma field. An electrically insulating layer is disposed between the plasma-generating substrate and the housing for preventing an arc of electricity from the plasma-generating substrate and/or the voltage to the housing.

Abstract: An electro-hydraulic lost motion system for variable valve activation including a master piston and an accumulation piston in a first bore, defining a hydraulic pressure chamber therebetween, in response to rotation of an engine cam. A slave piston in the engine head and hydraulically connected to the pressure chamber opens and closes an engine valve. A servo-valve behind the accumulation piston controls the mobility of the accumulation piston via a fluid control chamber. When the control chamber is made hydraulically rigid, the system actuates the engine valve. When the control chamber is vented through the servo-valve, the accumulation piston is movable in lost motion, preventing the engine valve from opening. All intermediate degrees of valve opening are possible. Preferably, the servo-valve, control chamber, accumulation piston, and a control piston are comprehended in a modular subassembly which may be positioned adjacent the master piston or the slave piston.

Abstract: A process for forming a microelectromechanical system (MEMS) device by a deep reactive ion etching (DRIE) process during which a substrate overlying a cavity is etched to form trenches that breach the cavity to delineate suspended structures. A first general feature of the process is to define suspended structures with a DRIE process, such that the dimensions desired for the suspended structures are obtained. A second general feature is the proper location of specialized features, such as stiction bumps, vulnerable to erosion caused by the DRIE process. Yet another general feature is to control the environment surrounding suspended structures delineated by DRIE in order to obtain their desired dimensions. A significant problem identified and solved by the invention is the propensity for the DRIE process to etch certain suspended features at different rates.

Abstract: A fuel injection apparatus for use in an internal combustion engine includes a fuel injector having a valve member which is operable to control injection of fuel through an injector outlet, a first supply path having a first path length for delivering fuel to an injector control chamber, a second supply path having a second path length for delivering fuel to an injector delivery chamber and a control valve for controlling fuel pressure within the injector control chamber so as to control movement of the valve member. An actuation means is arranged to vary at least one of the first and second path lengths in response to one or more injection parameters. Varying the first and/or second path length enables resonant pressure pulses within the control chamber and/or delivery chamber to be optimized so as to minimize the pressure differential across the valve needle at the instant of closure of the control valve to terminate injection, thus reducing needle closure response.

Abstract: A method and apparatus for cleaning incipient build-up of commutation byproducts from the commutators and brushes of a DC motor actuator for an air intake valve on an internal combustion engine. A controller for controlling the position of the intake air control valve is programmed via an algorithm to force the air control valve, abruptly and rapidly, to its open and/or closed position at least once at predetermined times in the engine's operating cycle, preferably immediately after engine shutdown. Such abrupt and rapid motion of the motor breaks loose such incipient build-up and thereby maintains the motor actuator at a high power output.
