Abstract: A heat exchanger assembly that includes an outlet header/manifold defining an outlet cavity, an outlet tube in fluidic communication with the outlet cavity, and a heat exchanger core. The outlet tube and the outlet cavity cooperate to reduce a temperature value range across the heat exchanger core by equalizing refrigerant distribution between the refrigerant tubes within the heat exchanger core. The length of the heat exchanger headers/manifolds may be increased for a predetermined packaging width because the outlet tube and inlet conduit may exit the headers/manifolds perpendicularly rather than axially, allowing the heat exchanger core width to be increased. The increased heat exchanger core width allows additional refrigerant tubes to be included in the heat exchanger core, providing decreased air pressure difference for air flowing through the heat exchanger assembly and increased heat capacity of the heat exchanger assembly.

Abstract: A dual view display system that includes a display device and a first louver device. The display device is configured to display a first image at a display location to a first person at a first location and display a second image at the display location to a second person at a second location. The first louver device configured to substantially restrict a first field of view of the first image to the first person. The system may also include a second louver device configured to substantially restrict a second field of view of the second image to the second person. Such an arrangement restricts the fields of view so that, for example, a vehicle driver can not lean over and view something intended only for a vehicle passenger, such as a movie.

Abstract: A thermal fuse integrated into an electrical circuit powering a heater element having a positive temperature coefficient includes at least one terminal in electrical connection with the heater element thereby connecting the heater element to a power source, and a solder jacket that mechanically retains the electrical connection between the terminal and heater element, wherein a biasing load is applied to the terminal when retained by the solder jacket, and wherein the terminal breaks connection with the heater element under the force of the bias when the solder jacket melts should the heater element overheat. By selecting the solder material forming the solder jacket according to its melt temperature, a temperature specific overheat protection for a heated fuel injector can be provided. Since the injector's metering circuit is separate from the thermal fuse circuit, the fuel injector remains operational even after the heater circuit is opened.

Abstract: An evaporator having a manifold and a plurality of refrigerant tubes extending downward in the direction of gravity from the manifold. The evaporator includes at least one PCM housing engaging the upper portion of the refrigerant tube for storing a phase change material. When operating in a first operating mode, heat is transferred from the phase change material to the refrigerant to freeze and cool the phase change material. When operating in a second operating mode, heat is transferred from the refrigerant to the frozen phase change material to condense the refrigerant. The condensed refrigerant falls downwardly through the tubes and receives heat from a flow of air to cool the air and evaporate the refrigerant. The evaporated refrigerant rises upwardly back to the low pressure of the cold manifold.

Abstract: A fluid level sensor for generating a warning upon, e.g., low fuel conditions in a vehicle gas tank. A vacuum conduit is disposed in the tank. The vacuum conduit has first and second vacuum openings and an actuation opening into which the fuel pump can pump fluid through a Venturi conduit to induce a vacuum. A first conduit extends from the first vacuum opening to a vacuum sensor outside the tank and a second conduit extends from the second vacuum opening. The second conduit extends down into the tank and terminates in an open end. When fluid in the tank drops below the opening the vacuum sensor senses a change in vacuum in the tank, triggering a low level alarm.

A rotor disposed within the stator includes vanes interspersed with the stator lobes to define alternating advance and retard chambers. A lock pin is provided for selective engagement with a lock pin seat for preventing relative rotation between the rotor and stator.

A lock pin oil passage communicates oil to and from the lock pin based on input from a lock pin control valve located outside of the camshaft phaser. The control valves are operational independent of each other.

The system provides a conditioned reformate stream having a predetermined sulfur concentration that gives an acceptable balance of minimal drop in initial power with the desired maximum stability of operation over prolonged periods for the fuel cell stack.
