Electronic Devices with Leakage-Based Object Detection
This abstract first appeared for US patent application 20250102656 titled 'Electronic Devices with Leakage-Based Object Detection
Original Abstract Submitted
an electronic device may include sensing circuitry that transmits a radar signal over one or more antennas. the sensing circuitry may receive a reflected radar signal over the antenna(s). transmission of the radar signal may produce a leakage signal that is combined with the reflected radar signal. a mixer may generate a beat signal based on the radar signal, the reflected radar signal, and the leakage signal. a sensing receiver may perform motion-based external object detection to detect the presence of an animate external object that is very close to the device. the sensing receiver may perform the motion-based detection based on time fluctuations in the power and/or phase of the signal without removing or cancelling the leakage signal.
