Publication number: 20240179738Abstract: Examples of the disclosure relate to communication methods and apparatuses, an access point, stations and a computer readable medium. An embodiment of the method comprises: determining, at an access point and based on determining that a direct link between stations based sensing procedure is triggered, a first station and a second station associated with the sensing procedure; and transmitting, to at least one of the first station and the second station, a sensing performing request for performing the sensing procedure. In this way, target sensing between non-access-point stations is achieved, such that sensing coverage is extended and a sensing effect is improved.Type: ApplicationFiled: November 28, 2023Publication date: May 30, 2024Applicant: Nokia Solutions and Networks OyInventors: Wenyi XU, Jian Guo LIU, Zhi Jie YANG, Yan MENG, Tao TAO, Wen Jian WANG, Chen Hui YE, Orhan Okan MUTGAN, Mika KASSLIN

Patent number: 11983109Abstract: An air freight rate data caching method and system. The method includes converting air freight rate data into a data format of a first-level cache, and storing same in the first-level cache; performing, on the basis of a flight origin city and a flight destination city, data fragmentation on the air freight rate data stored in the first-level cache so as to generate fragmented data; and storing the fragmented data, after same is validated, in a second-level cache. Each data node of the fragmented data cached in the second-level cache only includes part of the air freight rate data on which a fragmentation algorithm can be performed, and therefore, the horizontal expansion capacity of a cache system is improved relative to the case where cached data copies are all complete sets.Type: GrantFiled: July 8, 2020Date of Patent: May 14, 2024Assignee: TravelSky Technology LimitedInventors: Jinfang Du, Lingbin Meng, Wen Wen, Chunsheng Ju, Bing Liu, Yongbo Fei

Patent number: 11274543Abstract: The present disclosure relates to the technical field of rock mechanics, and in particular to a method for accurately measuring a reopening pressure of hydraulic fracturing induced fracture in a deep borehole. The method includes: pumping a fluid into a sealed inner space of a drilling pipe for energy storage; and opening a valve at a lower end of the drilling pipe such that energy is released from the fluid in the inner space of the drilling pipe under the action of pressure to inject the fluid into a test interval. In the method according to the present disclosure, a fluid is pumped into an inner space of a drilling pipe so that the inner space of the drilling pipe is used as a high-pressure fluid pump to inject the fluid in the inner space of the drilling pipe to the test interval until the closed fracture is reopened.Type: GrantFiled: July 5, 2019Date of Patent: March 15, 2022Assignee: Institute of Geomechanics, Chinese Academy of Geological SciencesInventors: Qunce Chen, Chongyuan Zhang, Dongsheng Sun, Xianghui Qin, Wen Meng, Quan Li, Ming Jin

Patent number: 11079462Abstract: Facilitation of determination of detailed location of a source signal is provided. In one embodiment, a device comprises a memory that stores computer executable components; and a processor that executes computer executable components stored in the memory. The computer executable components can comprise: a low-resolution computation logic component that implements a coarse algorithm and determines an approximate direction of arrival (DOA) of a source signal of an input signal, wherein the coarse algorithm uses both a coarse spatial grid and input data received from the input signal to determine the approximate DOA; and an error estimation logic component that estimates an estimation error of the coarse algorithm, and wherein the error estimation logic component uses the estimation error and the approximate DOA to determine a spatial interval range.Type: GrantFiled: October 24, 2017Date of Patent: August 3, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yi Ge, Jing Chang Huang, Xiao Xing Liang, Zhao Tai Pan, Wen Meng Xiong, Yu Ling Zheng, Yu Chen Zhou

Publication number: 20200364918Abstract: A facial recognition method for video conferencing requiring a reduced bandwidth and transmitting video and audio frames synchronously first determines whether a 3D body model of a first user at a local end has been currently retrieved or is otherwise retrievable from a historical database. Multiple audio frames of first user are collected and audio frequency at a specific range are filtered out. An envelope curve of the first audio frames and multiple attacking time periods and multiple releasing time periods of the envelope curve is calculated and correlated with lip movements of first user. Information packets of same and head-rotating and limb-swinging images of the first user are transmitted to a remote second user so that the 3D body model can simulate and show lip shapes and other movement of the first user.Type: ApplicationFiled: November 21, 2019Publication date: November 19, 2020Inventors: CHUN-TE WU, ZHI-GANG SHI, DONG-LIN LIU, WEN MENG, YU-QIANG ZHONG

Publication number: 20050056074Abstract: An inexpensive method of rapidly fabricating reactive metal (Zn, Al, Al-alloy, etc.) microscale structures including high-aspect-ratio microscale structures is disclosed. A high precision process uses conformal bond inhibitor coating and high temperature compression molding techniques to produce high quality, high aspect ratio metal structures. In one embodiment, following fabrication of an initial metallic microscale mold insert, an adhesion-promoting metal precursor layer and a ceramic bond inhibitor coating are conformally deposited onto the microscale mold insert. The microscale mold insert and a preselected reactive metal are then heated to an optimum temperature and compressed together. The mold insert is then extracted from the molded metal to produce a reverse image of the mold insert.Type: ApplicationFiled: September 12, 2003Publication date: March 17, 2005Inventor: Wen Meng
