  • Systems and methods for sensing current while minimizing measurement error and power loss
    Patent number: 9476921
    Abstract: A method may include deactivating a switch of a measurement circuit during a measurement portion of at least one voltage regulator phase, wherein each of the at least one voltage regulator phase is integral to a voltage regulator and each of the at least one voltage regulator phase comprises a power stage. The power stage may include a high-side switch for delivering electrical current to the at least one information handling resource in conformity with a first duty cycle of the high-side switch. The power stage may also include a low-side switch for sinking electrical current to an electrical ground in conformity with a second duty cycle of the low-side switch. The method may also include measuring a voltage across a sense resistor of the measurement circuit during the measurement portion, wherein the sense resistor is coupled in parallel with non-gate terminals of the switch.

  • Holder for circuit card
    Patent number: 6056579
    Abstract: A circuit card assembly (10) including a circuit card such as a terminator card (12) and a holder (14), insertable into a receptacle connector (20) of a mother board. Card (12) is snapped into the holder and maintained therein so that the assembly is manipulatable as a unit. Latch arms (56, 58) along side sections (52, 54) of the holder latch the assembly into guides (16, 18) of the receptacle connector.
