Patent number: 12136519Abstract: A low inductance capacitor with annular distributed cores is provided, which relates to the technical field of capacitors, and includes a lower bus bar, capacitor cores and an upper bus bar. Currents accessed from lower connection terminals flow to a closed end of the lower bus bar along copper bar connecting plates, and flow to the upper bus bar through the capacitor cores, and then flow out from upper connection terminals to form a loop. And positions of the copper bar connecting plates are in one-to-one correspondence with positions of the capacitor cores, and flow directions of the currents are opposite.Type: GrantFiled: June 28, 2024Date of Patent: November 5, 2024Assignee: SHANGHAI UNIVERSITY OF ENGINEERING SCIENCEInventors: Hui Guo, Yi Wang, Yansong Wang, Tao Yuan, Ningning Liu, Pei Sun, Xinhua Guo, Chi Xu, Shuang Huang, Xipei Ma, Chao Yang, Minghui Ma, Lifeng Ma

Patent number: 12077679Abstract: Disclosed are an intumescent fire-retardant coating with ultra-high corrosion resistance and a preparation method thereof. The fire-retardant coating is composed by water, wetting and dispersing agent, defoaming agent, composite carbon-forming catalyst, composite blowing agent, pentaerythritol, titanium dioxide, Mg(OH)2, mica powder, kaolin, anti-rust pigment, aluminum tripolyphosphate, VAE emulsion, freeze-thaw agent, film-forming aid, and thickener. On the basis of the existing fire-retardant coatings, the present disclosure adds a series of anti-corrosion, heat insulation fillers and salt spray resistance additives to achieve a certain salt spray resistance effect. The fire-retardant coating of the present disclosure has both fire-retardant and anticorrosive functions, does not contain organic solvents, is low in price, has high construction tolerance, and has broad application prospects in the field of intumescent fire-retardant coatings.Type: GrantFiled: November 24, 2021Date of Patent: September 3, 2024Assignees: FUJIAN SOUTH PEAK FIRE PREVENTION TECHNOLOGY CO., LTD., XIAMEN UNIVERSITYInventors: Jianghai Fang, Lizong Dai, Qingliang Liu, Yansong Liu, Huanhuan Xu, Chun'e Guo

Patent number: 11804187Abstract: An electronic device may include a display having an array of pixels and a backlight that provides backlight illumination for the array of pixels. The backlight may be a direct-lit backlight with a two-dimensional array of light-emitting diodes operable in a local dimming scheme. The electronic device may include control circuitry that provides pixel signals to the array of pixels and backlight signals to the backlight. The control circuitry may adjust the pixel signals and the backlight signals to compensate for brightness and color non-uniformity in the backlight. To compensate for image-dependent backlight non-uniformity, the control circuitry may simulate artificial backlight data based on the target image to be displayed and stored point spread information. To compensate for white-point-dependent backlight non-uniformity, the control circuitry may use measured actual backlight data that describes color variations across the backlight for a given target white point.Type: GrantFiled: June 24, 2022Date of Patent: October 31, 2023Assignee: Apple Inc.Inventors: Fang-Cheng Lin, Chengrui Le, Yi-Pai Huang, Suraj P Gorkhali, Tobias Jung, He Li, Yansong Liu
