Abstract: An integral center-mounted airhandling system includes a pair of blowers (211), an evaporator core (260), and a heater core (262) located within the center of the vehicle such that the vehicle can be readily adapted for left-side or right-side steering mechanisms. The blowers (211), evaporator core (260), and heater core (262) are preferably incorporated within a single, one-piece housing (213) so as to reduce materials, manufacturing, and assembling costs. The dual blowers (211) provide completely independent two zone operational and temperature control for the driver and passenger sides of the vehicle, as well as operational redundancy and conservation of electrical power within electrically powered vehicles.

Abstract: A rotary temperature control device which includes a vent pulley, a control pulley having a bevel gear associated therewith, a flexible cable which extends from the control pulley to the vent pulley and a shaft having a pinion gear associated therewith for driving the bevel gear, thus providing rotational movement to the vent pulley. The cable preferably has first and second ends and an intermediate portion therebetween which defines first and second segments, wherein the first and second ends are secured to the vent pulley while the intermediate portion is secured to the control pulley.

Abstract: An improved integrated circuit structure is disclosed which comprises a Vcc bus and a Vss bus having capacitance means coupled between the busses and distributed along the length of the busses to reduce the voltage spikes induced during switching. In a preferred embodiment, the capacitance means comprise one or more capacitors formed beneath one of the busses. Construction of MOS capacitors beneath one or more of the busses is disclosed.
