  • Patent number: 7258474
    Abstract: Headlamp systems are provided that form desired beam patterns from light supplied by semiconductor light sources. The systems include a source array of semiconductor light sources and a lens system to produce the spread components of desired beam patterns and a source array of semiconductor light sources and a lens system to produce the hot spot components of the desired beam patterns. Light from the semiconductor light sources of each source array is transferred to the respective lens system by a transfer device comprising a series of fiber optic cables which capture light emitted by the semiconductor light sources and emit the captured light adjacent the respective lens systems. One or both source arrays can include additional semiconductor light sources which are selectively illuminated or extinguished to provide steering hot spots in the beam pattern to illuminate areas adjacent the vehicle over which the vehicle will be turned.

  • Patent number: 7240894
    Abstract: A pulse width modulated solenoid control valve is described, wherein the valve includes a polymer fluid control body. The body includes a segmented fluid flow path for providing strength to the fluid control body assembly. Stand off ribs are provided to improve assembly into a control manifold. A casing forms an integral flux tube. A tapered push rod is used to reduce flux shorting.

  • Patent number: 7204240
    Abstract: An exhaust gas recirculation (EGR) arrangement having an intake manifold with a valve base assembly integrated with the engine's intake manifold. The valve base assembly has a valve seat positioned in the path of fluid flow through the valve base. A valve member is also contained in the valve base and is operably disposed in relation to the valve seat. An actuator is connectable with the valve base and with the valve member to open and close the valve seat in response to actuation of the actuator. The actuator can disconnect from the valve base and valve member.
