Patents by Inventor Barry Mark Fisher

Barry Mark Fisher 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).

  • Relative phase/amplitude detection system
    Patent number: 7492841
    Abstract: A base station signal is applied to antenna elements. One signal from a first element is electrically modified and evaluated in conjunction with a second, unmodified signal from a second element. The modified signal is further modified and again evaluated with the unmodified signal. The results of the two evaluations are compared to determine a relative phase and/or amplitude at the respective elements.
    Type: Grant
    Filed: January 30, 2003
    Date of Patent: February 17, 2009
    Assignee: Andrew Corporation
    Inventors: Barry Mark Fisher, Jonathon C. Veihl, Jeramy Scott Leonard, Donald G. Jackson

  • Repeater calibration system
    Publication number: 20040106382
    Abstract: A system calibrates the gain of a repeater by determining a value based on the difference between respective amplitude measurements made while the repeater is transmitting and while it is not. The value is compared to threshold data in order to determine whether repeater attenuation should be incrementally adjusted.
