ALEXANDRIA, Va., June 12 -- United States Patent no. 12,298,831, issued on May 13, was assigned to QUALCOMM Inc. (San Diego).
"Presence detection using compressive sampling" was invented by Diyan Teng (Sunnyvale, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "In some aspects, a device may obtain a signal of a vibration sensor. The device may perform compressive sampling of the signal by combining each set of data points, of a plurality of sets of data points of the signal, with a compressive sampling matrix to obtain a plurality of compressive measurements of the signal. The device may determine whether the plurality of compressive measurements are indicative of a person present in a vicinity of the d...
