Publication number: 20240161715Abstract: The present disclosure relates to a system for adjusting a level of luminance of a display unit. The system comprises a display unit to display content. Further, the system comprises a capturing unit to capture image of front view of the display unit. Furthermore, the system comprises a computing unit. The computing unit is configured to receive the image from the capturing unit. Further, the computing unit is configured to determine one or more target regions from plurality of regions in the image. The one or more target regions are determined based on weightage assigned to each of the plurality of regions. Furthermore, the computing unit determines effects of light incident on the one or more target regions. Thereafter, the computing unit adjusts the display of the content based on the effects of light.Type: ApplicationFiled: December 22, 2021Publication date: May 16, 2024Applicant: Continental Automotive Technologies GmbHInventors: Chee Wei Lee, Fook Wai Lee

Publication number: 20230370754Abstract: An integrated optical transceiver apparatus and an OLT are provided. A first splitter and a second splitter are integrated into a PLC structure of the apparatus. The first splitter is configured to output signal light of a first wavelength and signal light of a second wavelength, and output signal light of a third wavelength and signal light of a fourth wavelength. The second splitter is configured to separate the signal light of the third wavelength and the signal light of the fourth wavelength, output the signal light of the third wavelength, and output the signal light of the fourth wavelength. A first optical detector and a second optical detector are disposed on the PLC structure, where the first optical detector and the second optical detector are configured to convert, into electrical signals, the signal light output by the second splitter and the signal light output by the second splitter.Type: ApplicationFiled: July 26, 2023Publication date: November 16, 2023Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Shaowu WANG, Chee Wei LEE, Stevanus DARMAWAN, Yongping LIAO, Jinlin ZENG, Qian WANG, Ruiqiang JI, Jian JIAN

Publication number: 20230296844Abstract: A spot size conversion apparatus and a related device are provided. The spot size conversion apparatus includes a vertical spot size converter. The vertical spot size converter includes N geometric waveguides. A space between any two adjacent geometric waveguides is filled with a filling material. Each of the N geometric waveguides includes an incident surface and an emergent surface. The refractive index of the filling material is less than the refractive indices of the two adjacent geometric waveguides. Geometric feature sizes between respective incident surfaces and respective emergent surfaces of the N geometric waveguides gradually decrease in a first direction. The vertical spot size converter is configured to receive a first electromagnetic wave signal, perform vertical spot size processing on the first electromagnetic wave signal using the N geometric waveguides, and output a second electromagnetic wave signal.Type: ApplicationFiled: May 25, 2023Publication date: September 21, 2023Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Shaowu WANG, Chee Wei LEE, Qian WANG

Patent number: 11449294Abstract: A display system in a vehicle, including: one or more displays; at least one sensor determining a user's line of sight; a controller determining an active zone and a non-active zone of the one or more displays based on the user's line of sight. The one or more displays are configured to operate the active zone at an enhanced level as compared to the non-active zone. There is further provided a controller configured to rank content displayed on one or more displays in a vehicle according to an attention score determined by at least one sensor configured to measure gaze of a user based on the user's line of sight; and a display system including the controller. One of the displays is selected to display the highest ranked content. There is also provided a method of operating one or more displays in a vehicle using the disclosed display systems.Type: GrantFiled: October 3, 2018Date of Patent: September 20, 2022Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Chee Wei Lee, Fook Wai Lee
