US Patent Issued to Garmin International on June 30 for "Impulse response delay estimation" (Arizona Inventors)

ALEXANDRIA, Va., July 16 -- United States Patent no. 12,671,950, issued on June 30, was assigned to Garmin International Inc. (Olathe, Kan.).

"Impulse response delay estimation" was invented by Constantine Mouzakis (Phoenix) and Nicholas C. Ames (Tempe, Ariz.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for delay estimation of audio signals using an impulse response signal is provided. The method includes determining an energy envelope for the impulse response signal based on a moving average function of the impulse response signal. The method further includes determining an estimated delay of the impulse response signal based on at least one characteristic of the determined energy envelope. At le...
