Abstract: An ultra-high-efficiency switching power supply system integrating, into a single package, power conversion switches for multiple power supplies, an input power switching block, an output power switching block, control logic for controlling the power conversion switches and control input/output ports. This integrated multiple power supply package is called a Power Bridge and preferably implements the integrated components as one or more integrated circuit chips housed in the package housing. The Power Bridge is a bridge between the microprocessor of a portable computer and its internal and external power sources. The power supply system facilitates board design because the ultra-high-efficiency power module generally requires less space and generates less heat than conventional power supply circuitry. The power supply module improves power management because of improved communications connections between the power supply module control circuitry and other components, such as busses, other bridge modules and embedded controllers.

Abstract: An electrically conducting ceramic composition is described which can be utilized in an exhaust gas filter. The ceramic composition is compacted into discs or ceramic plates, are subsequently fired or sintered and then equipped with electrodes. Electrode leads are attached to the sintered filter discs or plates bearing electrodes which are subsequently connected to a power source. The ceramic filter discs or plates are supported and enclosed in a metallic housing. In another embodiment an insulator ring is placed between the housing and the ceramic filter plate. The housing enclosing the ceramic filter or filters, and equipped with electrodes and appropriate leads, is incorporated in the exhaust system of an internal combustion engine. The ceramic filter is used for trapping combustible carbon particles carried by the exhaust gas emanating from the engine. The carbon particles collected by the filter can be eliminated by heat generated electrically by means of an electrical current being passed through the filter between the electrodes when so desired.
