Jammie Chu 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).

  • Method and apparatus for sensing inter-modulation to improve radio performance in single and dual tuner
    Patent number: 9838053
    Abstract: A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.
    Type: Grant
    Filed: October 5, 2016
    Date of Patent: December 5, 2017
    Assignee: Panasonic Automotive Systems Company of America, Division of Panasonic Corporation of North America
    Inventors: Donald Thomas, Jason Hingerton, Tatsuya Fujisawa, Jammie Chu, Shree Jaisimha, Robert Baillargeon
