  • Patent number: 10078358
    Abstract: A power delivery network (PDN) including a battery, a set of regulators for generating supply voltages, and an integrated circuit (IC) including power rails configured to receive the supply voltages. The IC further includes an IC chip having a set of cores. The power rails includes a larger rail configured to provide a full range of currents, and the other smaller power rails each configured to provide lower range of currents. The IC includes multiplexers having first inputs coupled respectively to the smaller rails, second inputs coupled to the larger rail, and outputs coupled to the cores. When the smaller rail is able to supply the current needed by a core, the multiplexer is configured to couple the smaller rail to the core. When the smaller rail cannot supply the current needed by the core, the multiplexer is configured to couple the larger rail to the core.

  • Publication number: 20070153557
    Abstract: An AC/DC power adapter comprising a transformer and a rectifier bridge. The rectifier bridge replaces the conventional diodes with Schottky diodes. Due to a low voltage drop, the heat dissipated by the rectifier bridge is decreased and the power efficiency of the rectifier bridge is significantly increased.

  • Patent number: 6073678
    Abstract: Method and simplified apparatus for manufacturing aluminum alloys castings, for example those cast aluminum parts utilized in the manufacture of automobile engines: cylinder heads, engine blocks and the like; whereby the castings are cast in a plurality of semi-permanent-type molds, said molds each being movable to a plurality of processing positions along one of a plurality of preferably straight line paths (five in the preferred embodiment), wherein the operations of cleaning, core setting, casting, and casting extraction are performed on each mold at predetermined positions along its respective path and alternating said operations among the molds in order to permit minimization of the number of robot equipment and to increase the aggregate productivity of said molds, since any one processing operation can be handled by only a few (and preferably only one) robot arm moving across a plurality of mold paths (preferably seriatim), so that a given process step is performed at any one time only at one (or at lea
