  • Patent number: 6657404
    Abstract: A method and apparatus is disclosed to reduce power consumption of a load. In one embodiment a power control system selectively routes power directly to a load or to a power reduction device. A delay may occur prior to introduction of the power reduction device to fully energize the load. The power reduction device may operate in conjunction with signal modification device. The signal modification device modifies the signal provided to the load to achieve desired operation of the load. In one embodiment the power reduction device comprises a step-down transformer and the signal modification device comprises a capacitor. In one embodiment the power reduction device is selected to remove unwanted frequency components from the signal provide to the load. In various other embodiments the power control system may be configured to stagger start the load to minimize the peak draw of the load.

  • Patent number: 5892334
    Abstract: A adjustable timing light including a housing having bottom portion and a top portion. The top portion of the housing is pivotally coupled to the bottom portion of the housing such that the top portion has a first orientation situated perpendicularly with respect to the bottom portion and a second orientation positioned in coaxial relationship therewith. Also included is a light assembly positioned within an interior space of the top portion of the housing. The light assembly is adapted to emit light toward a top face of the top portion of the housing upon the receipt of power. A plurality of wires are in electrical communication with the light assembly and a coil and a spark plug of a vehicle.
