Publication number: 20240135008Abstract: Computer-implemented methods, apparatuses and systems for obtaining data authorization are described. In an example method, a first computing node in a trusted computing center receives an authentication request from a first provider. Authentication information is returned to the first provider, where the authentication information comprises a first code hash of a first computing logic running in the first computing node. A channel establishment request sent by the first provider is received after determining that the first computing node passes trusted authentication and the first code hash passes correctness verification. A first trusted channel is established between the first provider and the first computing node according to the channel establishment request. A target encryption key is received through the first trusted channel, thereby authorization to perform computation on a target encrypted shard corresponding to the target encryption key based on the first computing logic is obtained.Type: ApplicationFiled: December 29, 2023Publication date: April 25, 2024Applicant: Alipay (Hangzhou) Information Technology Co., Ltd.Inventors: Wuqiong Pan, Tao Wei, Tingting Li, Zhongtian Qian, Tianyi Li, Zhenqiang Wei

Publication number: 20220375923Abstract: An integrated circuit includes two N wells from two different devices in close proximity to each other with each N well biased by two different terminals. The N wells are at least partially surrounded by P type regions that are biased by a terminal. The integrated circuit includes conductivity reduction features that increase the resistivity of current paths to a P type regions of one device on a side closest the other device. The integrated circuit includes two conductive tie biasing structures each located directly over an N type region of the substrate and directly over a P type region of the substrate. The two conductive tie biasing structures are not electrically connected to each other and are not electrically coupled to each other by a conductive biasing structure.Type: ApplicationFiled: July 13, 2021Publication date: November 24, 2022Inventors: Guido Wouter Willem Quax, Dongyong Zhu, Feng Cong, Tingting Pan

Patent number: 11103996Abstract: A robot joint space point-to-point movement trajectory planning method. Joint space trajectory planning is performed according to the displacement of a robot from a start point to a target point during PTP movement and a limitation condition of a preset movement parameter physical quantity of each axis in a robot control system. An n-dimensional space is constructed by taking each axis of the robot as a vector, wherein n?2, and the movement parameter physical quantity of each axis of the robot is verified according to a vector relationship between the n axes of the robot, so that a trajectory planning curve of each axis of the robot satisfies the limitation condition of the preset movement parameter physical quantity. The method has a small amount of calculations and strong real-time performance, the movement curves are mild, the control time is optimal, and the algorithm execution effect is good.Type: GrantFiled: December 14, 2017Date of Patent: August 31, 2021Assignee: NANJING ESTUN ROBOTICS CO., LTDInventors: Riyue Feng, Jihu Wang, Zhengxian Xia, Tingting Pan, Bo Wu, Shuyi Jing
