ALEXANDRIA, Va., July 21 -- United States Patent no. 12,687,652, issued on July 21, was assigned to INSTITUTE OF GEOLOGY AND GEOPHYSICS, CAS (Beijing).
"Method and system for determining azimuth of marsquake/moonquake event" was invented by Weijia Sun (Beijing).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method and system for determining an azimuth of a marsquake/moonquake event. The method includes: filtering the original waveform data to obtain filtered waveform data; intercepting filtered waveform data of a set time length to obtain first arrival waveform data of a P wave; performing data analysis on the first arrival waveform data of the P wave, determining the first arrival waveform data of the P wa...
