Helen H. Ruan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Power savings in a voltage supply controlled according to a work capability operating mode of an integrated circuit
    Patent number: 7543164
    Abstract: Power is applied to a voltage supply. A signal that indicates reduced work capability in an integrated circuit (IC) that is being powered by the voltage supply is generated based on workload demand or conscious power and performance tradeoffs. This signal is applied to increase the power efficiency of the voltage supply, while the supply is powering the IC in its reduced work capability state.
    Type: Grant
    Filed: March 1, 2006
    Date of Patent: June 2, 2009
    Assignee: Intel Corporation
    Inventors: Helen H. Ruan, Don J. Nguyen
