Patent number: 12003462Abstract: A method includes, in accordance with some implementations, sending, a measurement station, a trigger frame to a signal source station, where the trigger frame carries pilot format information, and the pilot format information is used to indicate a sending time point of a signal frame triggered by the trigger frame, a quantity of times for sending the signal frame, and a transmission mode of pilot information in the signal frame. The measurement station receives an illumination frame from the signal source station, where the illumination frame is the signal frame triggered by the trigger frame. The measurement station analyzes pilot information in the illumination frame to obtain sensing information in the illumination frame, where the sensing information is used to indicate physical information of an object surrounding the signal source station and the measurement station.Type: GrantFiled: February 9, 2022Date of Patent: June 4, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Chenchen Liu, Huangxun Chen, Xiao Han, Rui Du, Meihong Zhang, Yunbo Li, Qian Zhang, Jia He

Publication number: 20240159011Abstract: An electronic well lid based on electric control travel switch control relates to the technical field of electronic well lids. The electronic well lid based on electric control travel switch control includes a well seat in splined connection with a sliding ring. The sliding ring is provided with a well lid lifting mechanism. A garbage collection mechanism is arranged on the well seat. An arc-shaped groove is formed in the sliding ring. An anti-deviation mechanism is arranged in the arc-shaped groove of the sliding ring. Square grooves are communicated with square holes by way of arrangement of the well lid lifting mechanism and cooperation of first fixing rings and the square grooves. Thus, a drainage speed of the device is increased, pedestrians may continue to pass safely on the well lid in a drainage process of the device, and the protection effect for pedestrians in the drainage process is improved.Type: ApplicationFiled: July 25, 2023Publication date: May 16, 2024Inventors: Yanchao LI, Yi YAN, Guoyong LIN, Zhi ZHANG, Yunbo LI

Patent number: 11977336Abstract: A method for improving a process model for a patterning process, the method including obtaining a) a measured contour from an image capture device, and b) a simulated contour generated from a simulation of the process model. The method also includes aligning the measured contour with the simulated contour by determining an offset between the measured contour and the simulated contour. The process model is calibrated to reduce a difference, computed based on the determined offset, between the simulated contour and the measured contour.Type: GrantFiled: May 14, 2019Date of Patent: May 7, 2024Assignee: ASML NETHERLANDS B.V.Inventors: Jen-Shiang Wang, Qian Zhao, Yunbo Guo, Yen-Wen Lu, Mu Feng, Qiang Zhang

Publication number: 20190196449Abstract: Various examples provide systems, methods, and computer-readable media for determining manufacturing data based on three-dimensional models. The manufacturing data can include data of outlines of planar models, e.g., corresponding to partitions of the three-dimensional model. Various examples include operating a manufacturing device, e.g., a cutter or mill, to produce physical components based at least in part on the manufacturing data. Various examples include determining the manufacturing data for a partition corresponding to a hollow extrusion of a contour of that partition. Various examples provide user interfaces permitting users to modify parameters of the manufacturing data, e.g., contour shape or extrusion thickness. Various examples permit cutting sheet material into components that can be folded into three-dimensional shapes and assembled into a three-dimensional model.Type: ApplicationFiled: May 5, 2017Publication date: June 27, 2019Inventors: Yunbo Zhang, Karthik Ramani
