Publication number: 20240107579Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with multiple transmit receive points (TRPs) in a frame based equipment mode. A wireless node (e.g., the UE and/or one or more of the multiple TRPs) may determine, among the UE and the multiple TRPs, an initiating node that acquired a current channel occupancy time. The wireless node may determine a transmission pattern that includes one or more idle periods based at least in part on a fixed frame period structure associated with the initiating node that acquired the current channel occupancy time. The wireless node may refrain from transmitting during the one or more idle periods, wherein the one or more idle periods include at least an idle period associated with the wireless node. Numerous other aspects are described.Type: ApplicationFiled: April 23, 2021Publication date: March 28, 2024Inventors: Luanxia YANG, Changlong XU, Jing SUN, Xiaoxia ZHANG, Shaozhen GUO, Rajat PRAKASH, Hao XU, Siyi CHEN

Patent number: 11119016Abstract: A digital image measurement device and method for the surface deformation of specimen based on sub-pixel corner detection is disclosed. This digital image measurement device is composed of a new type of image pressure cell, a complementary metal-oxide-semiconductor (CMOS) camera, a camera bracket, a flexible lens hood, a computer and matching measurement software. This method discretizes the specimen into several four-node finite elements by printing grids on the specimen and takes corners of the grids as the nodes of the finite elements; tracks the deformation of the feature points in real time by edge detection and corner detection based on sub-pixel; captures the deformation of the whole surface of the specimen by the two flat mirrors which are at an 120° angle behind the specimen; achieves the observation of the deformation of the whole surface by conducting splicing and error correction on the three images.Type: GrantFiled: October 18, 2017Date of Patent: September 14, 2021Assignees: Suzhou H-C Soil & Water Science and Technology Co., Ltd, Dalian University of TechnologyInventors: Longtan Shao, Xiaoxia Guo, Yonglu Liu, Chuan Huang, Mingming Wu, Xicheng Li, Pingxin Xia, Peng Ju, Xiao Liu, Chun Wang, Jie Xue, Ying Wang

Patent number: 10321181Abstract: The present invention provides a conditional access method for an intelligent operating system that comprises a trusted execution environment. A digital TV module acquires all channel messages and a control management message. A media play module distributes a DescramblerId and sends the acquired videoPid, audioPid, casId, ecmPid and emmPid and the descrambler message DescramblerId to a conditional access module. The conditional access module selects a registered conditional access application module according to the casId. The conditional access application module acquires corresponding ecm Data and emm Data from the digital TV module, and sends the ecm Data and emm Data to the conditional access module. The conditional access module sends the messages to a trusted application module. The trusted application module performs parse to acquire EK1, EK2 and ECW. The security chip controls a descrambler corresponding to the DescramblerId to perform descrambling according to the acquired messages.Type: GrantFiled: December 1, 2016Date of Patent: June 11, 2019Assignees: BEIJING NOVEL-SUPER DIGITAL TV TECHNOLOGY CO., LTD, ACADEMY OF BROADCASTING SCIENCE, STATE ADMINISTRATION OF PRESS, PUBLICATION, RADIO, FILM & TELEVISIONInventors: Zhifan Sheng, Qiang Wang, Jing Zhang, Zheng Li, Lei Wang, Zhijian Liang, Xiaoxia Guo, Dongfei Wang
