  • Publication number: 20070139983
    Abstract: An information handling system includes a buck converter, having a synchronous switch, to supply power to an electrical load. A first inductor is placed in series with the synchronous switch, and a second inductor is inductively coupled to the first inductor. A switched path recovers energy stored in the first inductor, via the second inductor, when the synchronous switch is open.

  • Publication number: 20070030196
    Abstract: A network, network device and method is disclosed. In one embodiment, a method includes transmitting communication signals from a first network node to a second network node, where the first and second network nodes comprise a network and each include a receiver portion and a transponder portion. The method further comprises receiving, by the first and second network nodes, position signals from a plurality of navigation beacons, and generating transmitter codes for the transponder portions using local code generators of the receiver portions.

  • Publication number: 20060083032
    Abstract: In a method and system for providing isolated power, a flyback controller includes a transformer operable to receive a primary voltage input and generate a secondary voltage output. A switch electrically coupled in series with a primary side of the transformer receives a control signal for controlling a duty cycle of the primary voltage. A controller is operable to generate the control signal responsive to receiving a plurality of inputs from the primary side. The controller regulates the secondary voltage output without receiving feedback input from a secondary side of the transformer by computing the secondary voltage as a predefined function of the plurality of the inputs when the switch is open.

  • Publication number: 20060045755
    Abstract: An information handling system (IHS) is provided which is cooled via an electromagnetic pump. The pump pushes a heat conducting liquid metal fluid in a heat conducting path away from a heat producing device such as a processor. The EM pump is driven by an AC electric current supplied to a transformer. The AC driven transformer supplies both a magnetic field and an electric current to the fluid in the pump. The system is configured such that the magnetic field and the electric current in the fluid are substantially orthogonal. Each time the AC electric current reverses polarity, the magnetic field and the electric current also each change polarity to force fluid out of the pump in the same direction during both the positive and negative going portions of the AC electric current cycle.

  • Publication number: 20050269187
    Abstract: A caterpillar traction apparatus (110), wherein two pairs of pulleys (122 & 123, 132 & 133) can be driven at different speeds, so that the linear member (40) being driven by the mechanism is subjected to either compression or extension forces.

  • Publication number: 20050162021
    Abstract: An information handling system (IHS) is provided which is powered by a zero voltage switching power supply. The power supply is capable of maintaining regulation even under very light loads. The supply includes first and second switches arranged in complementary configuration to deliver current to a load dependent inductor. This load dependent inductor acts as an energy source which supplies energy to parasitic elements in the first and second switches to aid in switching of the first and second switches during power supply operation.

  • Publication number: 20050015631
    Abstract: Power supply response to variations in power demand by a microprocessor is improved with a compensation loops that estimate changes in load current with improved speed. The load current estimate is performed in part with a capacitance feed forward compensation loop that senses voltage at output capacitors to replicate the current present in the capacitors and communicates the capacitor current adjusted by an optimized gain to the power supply for adjustment of power output. Capacitor current is replicated with a frequency domain filter having a pole that cancels out the zero created by power supply equivalent series resistance and capacitor capacitance. The capacitance compensation loop improves power supply response time to microprocessor power demand skews so that the size or number of output capacitors may be reduced while still maintaining power supply at the microprocessor to within desired voltage and current tolerances.
