Patent number: 11914093Abstract: A method for human movement classification includes a plurality of radio frequency (RF) antennas to expose a body surface of a human user to an E-field, at least a part of the human user positioned within a near-field region relative to the RF antennas. The plurality of RF antennas are scanned to determine ground-relative changes in electrical conditions. A differential-scanning subset of RF antennas are selected, including two or more RF antennas for which the changes in electrical conditions exceed a threshold. For each RF antenna in the differential-scanning subset, a set of antenna-relative changes in electrical conditions are determined by comparing the RF antenna to one or more other RF antennas in the differential-scanning subset as a plurality of pairs. Based at least in part on the ground-relative changes in electrical conditions and the antenna-relative changes in electrical conditions, a movement performed by the human user is classified.Type: GrantFiled: December 7, 2021Date of Patent: February 27, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Jouya Jadidian, Emily Po-Kay Chung, James Chester Meador

Patent number: 11872887Abstract: A display system and a vehicular head-up display system using the same is disclosed. The display system includes an image generating device, a polarization reflection film, a light-transmitting substrate, a curved wave plate, a curved reflector and a transparent substrate. The image generating device emits polarized light. The curved wave plate adheres to the reflective curved surface of the curved reflector through an optical adhesive. The curved wave plate and the reflective surface have the same curvatures. The reflective curved surface faces towards the polarization reflection film. When the curved reflector reflects the polarized light sequentially passing through the polarization reflection film and the curved wave plate to the polarization reflection film through the curved wave plate, the curved wave plate converts the polarization direction of the polarized light. Finally, the polarization reflection film reflects the polarized light to the transparent substrate to generate a virtual image.Type: GrantFiled: February 9, 2023Date of Patent: January 16, 2024Assignees: Interface Technology (Chengdu) Co., Ltd., Interface Optoelectronics (Shenzhen) Co., Ltd., Interface Optoelectronics (WuXi) Co., Ltd., General Interface Solution LimitedInventors: Wei Hung Tsay, Kun Da Lu
