  • Patent number: 8937469
    Abstract: Methods and apparatus for zero current detection and discontinuous conduction mode digital detection for a boost power factor correction converter based on a digital signal processor are disclosed. By effectively using resources in a processor with integrated high-speed comparators, simple detection can be accomplished with cost and performance over alternative detection methods. The methods and apparatus can be employed in an adaptive digital controller for mixed-conduction mode in the converter and can provide for lower total harmonic distortion and greater power factors than a non-adaptive controller.
    Type: Grant

  • Publication number: 20140081940
    Abstract: A system and method for transferring data between a charging system comprising a data control module and a removable memory is provided. The method comprises the data control module detecting a connection with a removable memory module and identifying and selecting a file on the removable memory. The data control module then obtains the selected file from the removable memory.

  • Publication number: 20080311192
    Abstract: The present invention relates to a particulate composition comprising enteric-coated glucosinolate and beta-thioglucosidase particles. The present invention further provides a method of converting glucosinolate to isothiocyanate in the small intestine comprising orally administering to a subject an enteric-coated chemoprotectant precursor composition comprising enteric-coated glucosinolate and beta-thioglucosinodase particles. In another aspect, uncoated glucosinolate and beta-thioglucosinodase particles may be provided in an enteric-coated capsule. Preferably, the glucosinolate is glucoraphanin and the beta-thioglucosidase is myrosinase. The enteric coating targets the compound for release in the small intestine where beta-thioglucosinodase enzyme converts glucosinolate to chemoprotectant isothiocyanate.

  • Patent number: 5080427
    Abstract: A roll-formed door beam is provided for a vehicle which has an elongated shaped including a hat shaped portion and one to two looping portions. The hat shaped portion includes an upper flat surface for attachment and downwardly extending sides. The looping portions includes a bottom flat surface for attachment and looping sides which loopingly extend backwardly toward the base of the hat shaped portion. The looping sides cooperate with the side of the hat portion to stabilize the beam during flexure thus increasing the strength to thickness ratio of the beam.
