  • Publication number: 20090304527
    Abstract: A pump unit (12) includes a pump housing (14), a pump cover (16), and an impeller (18) between the pump housing and pump cover. The pump housing and pump cover define a first channel (32) and a second channel (34) each having an inlet and an outlet. The impeller has first vanes (36) cooperating with the first channel and second vanes (38) cooperating with the second channel. The outlet of the second channel is constructed and arranged to provide fuel to an engine upon rotation of the impeller. A jet pump (38) is fluidly connected with the outlet of the first channel such that as the impeller rotates, the jet pump causes fuel to be drawn into the reservoir (37). Connecting structure (44, 44?) fluidly connects the first and second channels such that upon rotation of the impeller, fuel in the second channel flows into the first channel to prime the first channel.

  • Publication number: 20080278978
    Abstract: A method and apparatus for a power converter assembly charges a first capacitor and a second capacitor in parallel to a first voltage and at a first polarity, and then discharges the first capacitor and second capacitor in series at an output voltage that is greater than the input voltage and at a second polarity that is opposite the first polarity. This “charge pump” process is repeated and filtered to produce a continuous output.

  • Publication number: 20080205020
    Abstract: An integrated circuit includes a first lead frame and a second lead frame that extend from an overmolded circuit assembly. Each of the lead frames includes a piercing portion to pierce through insulation on a corresponding electrical conduit. The piercing portion of the lead frames also provides a wrap around feature to mechanically secure the wire to the corresponding electrical conduit. In this manner, several processes can be eliminated and are not required for the desired mechanical and electrical connection of the integrated circuit lead frame to corresponding electrical conductors.

  • Publication number: 20080187614
    Abstract: An overmolded electronic device includes a pre-mold assembly having a positioning pin that extends upward through a mold material into contact with an inner cavity of a mold. The positioning pin is disposed within a containment area that is defined by sets of ribs configured in and conformed on the pre-mold assembly. The positioning pin thereby is sealed within the containment area that is in turn sealed from the remainder of the electronic device that prevents the intrusion of moisture or other contaminants into undesirable locations of the electronic device.

  • Publication number: 20080136590
    Abstract: An example receiver/transmitter for a passive start and entry system switches between amplitude shift keyed modulation and frequency shift keyed modulation to maintain clear uninterrupted and dependable communication with a remote transmitter in the presence of interfering signals. The receiver/transmitter is switched to receive incoming FSK signals in response to the RSSI becoming saturated by undesired signals. The switch to FSK signal modulation occurs by signaling the remote transmitter to change over and begin sending FSK modulated signals. The FSK modulated signals are then received without significant interference.

  • Publication number: 20080106367
    Abstract: A passive entry and start system transmits a neutral signal over all the antennas except for that antenna that is proximate an area in which transmission to an identification device is desired. Accordingly, the area of a vehicle and those physical features that are proximate and associated with the area is isolated to prevent undesired operation of other vehicle mechanisms.

  • Publication number: 20080098589
    Abstract: A method of fabricating an antenna includes the step of stamping an initial set of openings within a metal strip and then plating that metal strip on all exterior surfaces. Initial openings define portions of features of the completed antenna that require plating on all surfaces. Once the metal coil has been plated the metal strips are fed through a final stamping process that makes final cuts that correspond with the initially made openings. The final cuts are on surfaces that do not require plating on all of the exterior surfaces.
