Patent number: 11982649Abstract: A shear testing system and method of thermo-seepage-mechanical field and engineering disturbance coupling under deep and complex condition are provided. The shear testing system can be used in conjunction with an axial pressure application device to simplify the structure, save costs, and facilitate a triaxial confining pressure—temperature—axial pressure—torsional shear coupled test on a rock specimen. The shear testing system can achieve the following three purposes. First, the shear testing system can convert an axial pressure into a torsional shear force through a transmission mechanism of a power conversion assembly. Second, the shear testing system can apply an axial pressure to the rock specimen fixed between two specimen fixing heads, through a pressure shaft of an axial pressure mechanism. Third, the shear testing system can apply a triaxial confining pressure and a temperature field to the rock specimen.Type: GrantFiled: January 16, 2024Date of Patent: May 14, 2024Assignee: SICHUAN UNIVERSITYInventors: Jianfeng Liu, Heping Xie, Chao Ma, Fujun Xue, Jingjing Dai, Jianxiong Yang, Lu Wang, Zhijun Wu, Xiangchao Shi, Houquan Zhang, Yinghui Ma, Tao Meng, Defu Zhu, Shaoqi Kong

Publication number: 20240152520Abstract: Relation network data query includes receiving a query request for an edge using a first node as a starting node, where the edge satisfies a specified filter condition comprising that the edge has a first edge data item and a corresponding first data value. Multiple index blocks associated with the first node are obtained from a non-volatile storage storing a relation network. A first index block corresponding to the first edge data item is determined from the multiple index blocks based on a correspondence between an index block and an edge data item, where the first index block comprises multiple data values of the first edge data item and location information of edges having the multiple data values and using the first node as starting nodes. Location information of an edge having the corresponding first data value is determined from the first index block and the edge obtained.Type: ApplicationFiled: October 24, 2023Publication date: May 9, 2024Applicant: Alipay (Hangzhou) Information Technology Co., Ltd.Inventors: Lin Yuan, Zhijun Fu, Jin Jiang, Bingpeng Zhu

Patent number: 8914699Abstract: A first subscriber unit (SU) operating in a two-way radio frequency (RF) communications system having at least one fixed terminal, one or more channels, and a plurality of subscriber units, generates a first burst of data for transmission to the at least one fixed terminal. The first SU calculates a cyclic redundancy check (CRC) or checksum value over (i) at least a first portion of the first burst of data and (ii) at least a portion of a first private data. The first SU transmits the first burst of data and the calculated CRC/checksum value, but not the first private data, to the at least one fixed terminal. The fixed terminal then calculates its own CRC/checksum over the received burst and its own copy of the first private data, and compares the result with the received CRC/checksum. The fixed terminal authenticates the received burst if the values match.Type: GrantFiled: April 30, 2012Date of Patent: December 16, 2014Assignee: Motorola Solutions, Inc.Inventors: Satyanarayan R.
