摘要： The present invention is a system and method for sensing the voltage at multiple sense points. The present invention acquires optimal feedback from a plurality of sources including those integrated on the same motherboard, for populated or unpopulated connectors and for adapter cards plugged into the connectors, for the purpose of controlling the voltage regulator output. The voltage regulator, connected to a logic system, provides voltage to those connectors needing the voltage.

摘要： An apparatus which connects/disconnects battery from a load such as a computer system includes a first circuit arrangement which sets a first reference voltage level at which the energy source is connected through an FET device to the computer system, a second circuit arrangement that sets a second voltage level at which the energy source is disconnected by the FET device from the computer system and a third circuit arrangement which controls the FET device so that said FET device is forced into either its ON or OFF state once one of the reference voltages is reached. A second apparatus which reduces power dissipation in a battery charger power device by forcing the input voltage to track the battery voltage as the battery charges/discharges.

摘要： A bus bar distributes power to a plurality of electronic components supported on a printed circuit board. One embodiment of the bus bar comprises a plurality of compressible contact pads made from an electronically conductive polymer, spaced along the bus bar for contacting conductive contacts that are coupled to a power domain or individual electronic component. The pads may be secured to the bus bar and the conductive traces using an electronically conductive epoxy adhesive. Rivets may then be used to secure the bus bar to the printed circuit board and compress the pads, which conform to the printed circuit board to make a reliable electrical connection with the conductive traces. The bus bar further comprises a plurality of current sense points disposed adjacent to the pads for measuring the amount of current provided to each power domain.
