  • Patent number: 7443049
    Abstract: A charging system for a battery of a vehicle comprises an electrical interface module that includes first and second electrical interfaces. An inverter module communicates with the electrical interface module and the battery and has a first state and a second state. In the first state, the inverter module allows the battery to be charged through the first electrical interface when a voltage source is connected to the first electrical interface, the vehicle is off, and a charge level of the battery is less than a threshold. In the second state, the inverter module allows the battery to provide power to the second electrical interface when a voltage source is not connected to the first electrical interface, the vehicle is on, and/or the charge level of the battery is greater than or equal to the threshold.

  • Patent number: 6700795
    Abstract: The architecture of an automotive wiring, power distribution and accessory control system is described. The system comprises semi-custom two-tier nodes which are distributed in locations around the vehicle to service load devices associated with or found in different regions of the automobile topology. A multiplexed control network interconnects the nodes along with a two-wire bus. Each node consists of a first common board carrying a microcontroller and a basic number of FET driver switches associated with a basic level of accessorization for that region of the vehicle. Each node further comprises a second larger pass through board which supports the first common board in spaced parallel relationship therewith and which carries terminal connectors. The larger pass through board has vacant locations for the addition of FET drivers needed for higher levels of accessorization. These locations are preconnected to the microcontroller but are unused in vehicles with lower levels of accessorization.

  • Patent number: 6580219
    Abstract: An electrical control circuit for an automotive lamp module having an integrated ON/OFF switch to activate and deactivate the driver circuit associated with the lamp such that the driver circuit is only turned on when either the primary ON/OFF switch or a remote, door-ajar switch is closed. A microprocessor is used to respond to low-level current conditions indicative of a closed switch. A timer turns the driver OFF after a predetermined duration of continuous operation.

  • Patent number: 6379178
    Abstract: An adjustable power point for use in a vehicle, movable from at least one home position to other locations in the vehicle that are suited for connecting various electrical devices. In one form, the power point is connected to a retractable power cord, and is normally retained in a home socket, for example in the dashboard near the driver console. In another form, the power point is slide-mounted in a track structure formed in a portion of the vehicle, for example the instrument panel, capable of being longitudinally adjusted between various home positions along the length of the track.
