Publication number: 20240162100Abstract: A cover plate may include a plate body and a gasket. The plate body includes a first face and a second face that are disposed back from each other, and the plate body is provided with a first hole. The gasket includes a body part, and the body part is provided with a second hole, and in a direction from the first face to the second face, the first hole penetrates through the plate body, and the second hole penetrates through the body part. When the cover plate is applied to the power module, each pin of the power module may pass through one second hole and be inserted into one first hole in a one-to-one correspondence, and the pin is in interference fit with the corresponding first hole. In this way, the plate body may limit each pin, thereby improving a position degree of the pin.Type: ApplicationFiled: January 19, 2024Publication date: May 16, 2024Applicant: Huawei Digital Power Technologies Co., Ltd.Inventors: Haiwen ZHANG, Zhiling LIU, Yanbo WANG

Patent number: 11946799Abstract: A distributed fiber-optic acoustic sensing system and a signal processing method. The distributed fiber-optic acoustic sensing system is based on a high spatial resolution distributed fiber-optic acoustic sensor. The interval between adjacent sensing units is centimeter or millimeter level. Through specific digital signal processing, signal enhancement can be realized, noise in the system and environment are suppressed, at the same time, problems such as interference fading is solved, and the sensor signal-to-noise ratio of subunits can be increased by two to three orders of magnitude. Each subunit can serve as an independent high-sensitivity sensor for sensing. The multiple subunits can form one or more new sensor arrays. The azimuth estimation and spatial orientation of signal sources can be realized by the array signal processing method.Type: GrantFiled: June 7, 2021Date of Patent: April 2, 2024Assignee: Shanghai Institute of Optics And Fine Mechanics, Chinese Academy of SciencesInventors: Haiwen Cai, Bin Lu, Zhaoyong Wang, Lei Ye, Qing Ye, Ronghui Qu

Publication number: 20230402810Abstract: The present invention provides a way to use anisotropic laser gain media to make a laser that can lase in two longitudinal modes at different wavelengths with orthogonal polarizations. The two longitudinal mode (LM) laser output can be separated to generate two single LM outputs. This type of lasers can also be used to generate low noise continuous wave (CW) harmonics through intracavity harmonic generation.Type: ApplicationFiled: March 7, 2023Publication date: December 14, 2023Applicant: Pavilion Integration CorporationInventors: Haiwen Wang, Ningyi Luo, Jihchuang Robin Huang

Publication number: 20230335969Abstract: This invention proposes to use a specially designed layered nonlinear optic (LNO) for intracavity harmonic generation. The LNO generates the harmonic and guides the generated harmonic beam to a different path from the fundamental beam path with total internal reflection, a phenomenon that all lights are reflected when lights in one (“internal”) optic strike sufficiently obliquely against the interface with a second (“external”) optic, in which the refractive index is lower than that in the internal optic. No coating is necessary for the harmonic inside the fundamental beam laser cavity. The generated harmonic beam does not travel through any surface inside the fundamental beam cavity, either. Hence this invention improves the reliability of intracavity harmonic generation laser especially if the harmonic is in the UV range.Type: ApplicationFiled: August 24, 2022Publication date: October 19, 2023Applicant: Pavilion Integration CorporationInventors: Haiwen Wang, Jihchuang Robin Huang, Ningyi Luo

Publication number: 20230288705Abstract: An output grating for waveguide of a head-mounted display is configured to suppress the (1, 1) diffraction order of the output grating. The grating has a design of two or more materials having different refractive indices. The design is repeated periodically in a first dimension and repeated periodically in a second dimension, to form a two-dimensional pattern. A refractive index of the two-dimensional pattern is approximated by a two-dimensional Fourier series comprising a first coefficient of order (1, 0), a second coefficient of order (0, 1), and a third coefficient of order (1, 1). The third coefficient is less than half the first coefficient and less than half the second coefficient, such that light from the (1, 1) diffraction order of the grating is suppressed.Type: ApplicationFiled: March 11, 2022Publication date: September 14, 2023Applicant: Meta Platforms Technologies, LLCInventors: Haiwen Wang, Yu Shi, Siddharth Buddhiraju, Hee Yoon Lee
