Abstract: In a heat transfer system (10), an upper coolant chamber (31) and a lower coolant chamber (24) of a typical engine, such as an internal combustion engine, fuel cell, boiler, or other engine for converting fuel to thermal energy, are formed adjacent to the heat-rejecting components of the engine and are hermetically sealed to prevent exposure of heat-transfer liquid within the chambers to the engine's ambient atmosphere.

Abstract: A blank formed from electrically conductive sheet material defines a continuous conductive path which includes two terminal ends and at least three loops disposed along the path. The blank is foldable at preselected folding locations on the path to position the loops in overlying relation to one another, and the blank is preferably formed with the loops disposed along the conductive path in substantially the same plane. The blank is used to form a multi-turn planar winding for a magnetic device such as, for example, an inductor or transformer which may be incorporated into electrical circuits such as power supplies. The planar magnetic device provides a low overall volume and profile, as well as a substantially higher volume or surface area of conductive material per turn of the winding compared to conventional wire or etched windings to provide a higher current carrying capacity and fewer turns compared to conventional windings.

Abstract: A vehicle position determination system for determining the position of a moving vehicle having a transponder includes a first and second antennas operable to receive periodic radio frequency data signals from the transponder when the transponder is moving through a first or second predetermined coverage zone, respectively. The first and second coverage zones partially overlap and each have a width that is orthogonal to the travel path of the moving vehicle and a length that is parallel to the travel path of the moving vehicle. A processor counts the number of periodic data signals received by each of the antennas from the transponder during a time period and determines based on the count a probable location of the vehicle. The vehicle location information can be provided to an imaging system to discriminate between transponder and non-transponder equipped vehicles.
