  • Publication number: 20090034199
    Abstract: A heat sink assembly includes a heat sink and a clip for mounting the heat sink to an electronic component of a printed circuit board. The heat sink includes a base and a plurality of fins extending from the base. The clip includes a pressing member and a pair of elongated arms formed on opposite ends of the pressing member. The pressing member has a lower portion protruding toward the base of the heat sink. A middle one of the fins extends upwardly through the pressing member in a manner such that the lower portion of the pressing member resiliently abuts against the heat sink. The two arms are located on opposite lateral sides of the heat sink and bent downwardly to engage with the printed circuit board so that the pressing member exerts a force on the heat sink toward the electronic component.

  • Patent number: 7442453
    Abstract: A decontamination procedure for a fuel cell power plant (10) includes operating the plant to produce electrical power for an operating period, and then terminating operation of the plant (10) for a decontamination period, and then, whenever optimal electrical production of a plant fuel cell (12) is reduced by at least 5% by contaminants adsorbed by fuel cell electrodes (24, 42), decontaminating the fuel cell (12) of the plant (10) during the decontamination period by oxidizing contaminants adsorbed by electrodes (24, 42) of the fuel cell. Oxidizing the contaminants may be accomplished by various steps including exposing the electrodes (24, 42) to flowing oxygen; to heated flowing oxygen; to a sequence of start-stop cycles; and, to varying controlled potentials.

  • Publication number: 20080251795
    Abstract: A photoelectric element package with temperature compensation includes a substrate, and a first light-emitting element, a second light-emitting element, a photosensitive element, and a drive element disposed on the substrate, all of which are disposed in an internal space formed by a first casing joined with a second casing. Alternatively, the second light-emitting element and the photosensitive element are disposed in an internal space of a third casing. By adding the second light-emitting element, the photosensitive element can sense the light emitting intensity accurately in the absence of other interferences, so as to feed back the current operating state of the light-emitting element. A temperature compensation function is achieved by a laser driver, so as to reduce the influence of temperature on the light-emitting element, such that the light-emitting element emits light in an accurate intensity.

  • Publication number: 20080244363
    Abstract: A parallel-to-serial conversion method for IBMA in a Reed Solomon decoder is used for obtaining discrepancies in IBMA iterations, thereby acquiring an error location polynomial and an error value polynomial. Syndrome sequences for the calculation of discrepancies in IBMA iterations have a fixed length. The number of syndromes is t+1, where t is the largest number of symbols that can be corrected of the error location polynomial. The feature that syndrome sequences have the same length is based on the fact that the discrepancies are not affected if the coefficients of polynomial orders of the error location polynomial are zero.
