Abstract: The present invention involves a vehicle for passengers having a passenger safety system. The system has a crash sensor, a vehicle seat with a weight sensor assembly, an air bag and an air bag controller. The crash sensor is capable of providing a signal when the vehicle experiences an impact force of a predetermined magnitude. The vehicle seat is capable of supporting a vehicle occupant, with a seat frame member attached to a vehicle floor pan. The seat frame member has a rigid end and a resiliently flexible end, the resiliently flexible end able to resiliently deflect with respect to the vehicle floor pan upon experiencing a force due to the weight of the vehicle occupant. The sensor assembly has a cantilevered beam, a fulcrum, and a sensing device.

Abstract: A heat sink for an electrical device is distinguished by a confining plate extending parallel to and along each lateral side of fins and extending upwardly from a top surface of a base to a bottom surface of a lid to define an outlet-chamber extending from the outer ends of the fins and outside of the fins back toward a vertical nozzle. A cylindrical outlet is disposed on the inlet axis outwardly of each of the confining plates for directing fluid flow on each side of the fins. The outer wall presents a pair of oppositely facing apexes and the outer wall curves outwardly from each apex in opposite directions in a generally heart-shape around and spaced from the fins and back into the outlets to define the outlet-chambers which increase in volume from the ends of the fins back toward the outlets to reduce the fluid pressure.

The injection system may include a valve arrangement in the form of a three-position valve or may include a shut off valve for controlling the supply of fuel through the fuel supply passage.

Abstract: Apparatus and method for securing a fuel rail to a cylinder head of an engine wherein a plurality of passageways are formed through the fuel rail perpendicular to the longitudinal axis thereof.

Abstract: In a solid-oxide fuel cell assembly, at least one positive displacement air supply (PDAS) pump supplies at least a portion of the air required for various functional air streams through the assembly. Mass air flow through each PDAS pump is readily controlled to a predetermined flow by controlling the rotational speed of the pump, obviating the need for an MAF sensor and control valve. Preferably, each different air stream through the assembly is controlled by its own PDAS pump, sized for the required flow, allowing each to operate at its optimal pressure and thereby minimizing the parasitic electrical cost of providing air to the SOFC assembly.

Abstract: A motorized cam actuator for linear actuation of an apparatus. An actuating motor shaft is fitted with a bushing having first and second opposed flats and a threaded portion at an outer end thereof. With the motor mounted to a pedestal, the bushing is rotated on the shaft to a predetermined angular position such that assembly stack up is cancelled. The bushing is then fixed to the shaft by welding. A cam with a central opening is mounted onto the bushing, the opening having flats for mating with the flats on the bushing. The cam is mounted onto the bushing and is secured thereto by a nut. This arrangement eliminates any relative motion between the bushing and the motor shaft and prevents stress on the weld joint from reaching failure levels.

Abstract: A system and method of assessing the driving task demand on the driver of a vehicle, and further controlling one or more devices on the vehicle as a function of the assessed driver demand is provided. The method includes sensing a coverage zone in relation to a vehicle, determining a presence of one or more objects in the sensed zone, measuring speed of each detected object in the sensed zone, determining a variation in speed of one or more sensed objects, and determining a driving task demand signal indicative of driving task demand of the vehicle as a function of the measured speed variability. The method controls one or more devices on the vehicle based on the driving task demand signal. Alternately, the driving task demand signal is determined based on vehicle speed.

A sensor is responsive to a current transmission shift position and emits a second signal corresponding to the sensed current transmission shift position. A controller is responsive to the switch and to the sensor.
