Abstract: A headlamp assembly for a vehicle includes a housing for coupling the headlamp assembly to a vehicle. The housing includes a reflector and a planar heat sink is positioned therein. The planar heat sink structure includes a first surface and a second surface for supporting a circuit board, a first light emitting diode assembly, and a second light emitting diode assembly. The headlamp assembly is adapted to emit a high beam and a low beam and the headlamp assembly is completely bisected by the planar heat sink structure.

Abstract: A headlamp assembly having a mechanism for reducing water based contamination is disclosed. The mechanism includes a lens assembly having an outer lens and an inner lens. A heating element may be disposed between the inner and outer lenses. Alternatively, inner and outer lenses may be spaced apart having a passage formed therebetween thorough which fluid may travel. Heat from light emitting diodes and a circuit board may be directed toward the outer lens through passages formed in the headlamp assembly.

Abstract: Methods and system are provided for a vehicle truck assembly which includes a spring coupling an axle carrier to a truck frame. In one example, the system comprises a substantially vertically-mounted hydraulic actuator which generates hydraulic forces between the axle carrier and the truck frame. The actuator includes a cylinder, a piston, and a piston rod. Further, the actuator is coupled between the axle carrier and the truck frame with longitudinal and lateral play so that the axle carrier can move laterally and longitudinally with respect to the truck frame while the actuator applies hydraulic force.

Abstract: Truck assemblies, systems and methods are provided for transferring weight supported by various wheels, and axles. An example truck assembly may include a truck frame element, and a carrier coupled with the truck frame element. A bias may be configured to bias the carrier away from the truck frame element. An actuatable linkage arrangement may include a compliant linkage coupled with the carrier. The compliant linkage may pull the carrier against the bias in a first direction.

Abstract: A laboratory test for general tire durability can produce results comparable to the GM-ATE road test. A passenger tire is mounted in a test machine and run at approximately 50 mph (80 kph), at maximum rated inflation pressure, with at least 100% maximum rated radial load, with approximately 25% of the test duration being performed with lateral force comprised of approximately equal portions of right and left steering, the remainder of the test being performed without lateral force (straight portions). A test segment comprises repeating a loading cycle a plurality of times until approximately 5000 miles have accumulated, and multiple test segments are performed until 16,000 miles have been accumulated. The test is paused and the tire is visually inspected several times during the test segments, including at the end of the test.

Abstract: An apparatus and method for the cordless remote control of a filling function of a mobile vehicle that includes a signal transmitter (12) and a liquid level sensor (14) that is mounted on a tank (18) of a mobile vehicle (16). The liquid level sensor (14) transmits a full signal to a remote signal receiver (22) by way of the signal transmitter (12). The full signal closes a control valve (26) interupting the flow of the fluid to the tank (18) by way of a conduit 28. An adjustable timer (44) provides a system safety back-up signal that closes the valve (26) if the full signal is not received within a preset time period. This apparatus and method can be operated in a semi-automatic mode or an automatic mode by the addition of an adjustable delay clock/timer (42). Audible and/or visual indicators are provided for monitoring the status of the filling operation.
