Patents by Inventor Yevgen P. Barsoukov

Yevgen P. Barsoukov 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).

  • Systems, methods and circuits for determining micro-short
    Patent number: 8049465
    Abstract: Various systems and methods for determining micro-shorts are disclosed. For example, some embodiments of the present invention provide battery systems including a determination of potential micro-shorts based on rate of change of state of charge. Such battery systems include: a battery, a processor, and a computer readable medium. The computer readable medium includes instructions executable by the processor to: determine a rate of change of the state of charge of the battery; compare the rate of change of the state of charge of the battery against a threshold; and indicate a potential failure where the result of the comparison is beyond the threshold.
    Type: Grant
    Filed: October 10, 2007
    Date of Patent: November 1, 2011
    Assignee: Texas Instruments Incorporated
    Inventors: Yevgen P. Barsoukov, Garry Elder, Jinrong Qian
  • Systems, methods and circuits for determining potential battery failure based on a rate of change of internal impedance
    Patent number: 7856328
    Abstract: Various systems and methods for determining potential battery failure are disclosed. For example, some embodiments of the present invention provide battery systems that include a battery, an embedded processor and a computer readable medium. The computer readable medium includes instructions executable by the embedded processor to measure at least one characteristic of the battery; to calculate a rate of change of internal impedance of the battery based at least in part on the at least one characteristic of the battery; and to determine a potential failure condition based on the rate of change of internal impedance of the battery.
