Patent number: 11119322Abstract: An imaging display system in the field of augmented reality technology comprises a waveguide structure (14) disposed on an outer surface of an exit surface (7) of a polarization beam splitter (3) of an optical engine module (A). The waveguide structure is tubular. One end (15) of the waveguide structure is connected to the exit surface and together with the exit surface forms a preset angle (?). The other end of the waveguide structure is a free end. The imaging display system expands an eye motion box (EMB) by means of the waveguide structure. The preset angle formed between the waveguide structure and the exit surface causes light (22) incident on the waveguide structure to undergo total internal reflection inside the waveguide structure.Type: GrantFiled: January 26, 2018Date of Patent: September 14, 2021Assignee: YUTOU TECHNOLOGY (HANGZHOU) CO., LTD.Inventors: Liang Guan, Kun Li

Patent number: 10701534Abstract: In a vehicle-to-vehicle communication system, an intersection-located road side unit (RSU) having two omni-antennas applies spatial filtering to the antennas' RX signals to recover first and second overlapping basic safety messages (BSMs) concurrently transmitted by two intersection-approaching vehicles that have no direct line of sight (NLOS) between them. The RSU retransmits each BSM for receipt by the other vehicle using either an omnidirectional retransmission technique in which the two messages are sequentially transmitted using an omnidirectional beam-pattern, a directional retransmission technique in which the two messages are sequentially transmitted using directional beam-patterns, or an XOR retransmission technique in which the RSU applies an XOR operation to the two BSMs and transmits the resulting XOR message using an omnidirectional beam-pattern. A receiving vehicle can apply an XOR operation to the XOR message and a local copy of the first BSM message to recover the second BSM message.Type: GrantFiled: July 30, 2018Date of Patent: June 30, 2020Assignee: NXP B.V.Inventors: Thanh Hieu Nguyen, Md Noor-A-Rahim, Yong Liang Guan, Hong Li
