Patent number: 11869227Abstract: Image recognition may include obtaining a first image, segmenting the first image into a plurality of first regions by using a target model, and searching for a target region among bounding boxes in the first image that use points in the first regions as centers. The target region is a bounding box in the first image in which a target object is located. The target model is a pre-trained neural network model configured to recognize from an image, a region in which the target object is located. The target model is obtained through training by using positive samples with a region in which the target object is located marked and negative samples with a region in which a noise is located marked. The target region is marked in the first image to improve accuracy of target object detection in an image.Type: GrantFiled: April 8, 2021Date of Patent: January 9, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Zi Jian Zhang, Zhong Qian Sun, Xing Hui Fu, Wei Yang

Patent number: 11856402Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.Type: GrantFiled: November 15, 2021Date of Patent: December 26, 2023Assignee: Apple Inc.Inventors: Xiangying Yang, Shu Guo, Lijia Zhang, Qian Sun, Huarui Liang, Fangli Xu, Yuqin Chen, Haijing Hu, Dawei Zhang, Hao Duo, Lanpeng Chen

Patent number: 11792159Abstract: Some embodiments of the invention provide a method for deploying network elements for a set of machines in a set of one or more datacenters. The datacenter set is part of one availability zone in some embodiments. The method receives intent-based API (Application Programming Interface) requests, and parses these API requests to identify a set of network elements to connect and/or perform services for the set of machines. In some embodiments, the API is a hierarchical document that can specify multiple different compute and/or network elements at different levels of compute and/or network element hierarchy. The method performs automated processes to define a virtual private cloud (VPC) to connect the set of machines to a logical network that segregates the set of machines from other machines in the datacenter set. In some embodiments, the set of machines include virtual machines and containers, the VPC is defined with a supervisor cluster namespace, and the API requests are provided as YAML files.Type: GrantFiled: June 10, 2020Date of Patent: October 17, 2023Assignee: VMWARE, INC.Inventors: Zhengsheng Zhou, Qian Sun, Danting Liu, Donghai Han

Publication number: 20230244591Abstract: Some embodiments provide a method for monitoring a container cluster that includes multiple nodes on which application resources are deployed. The method deploys an agent on each node of a set of nodes of the cluster. Each agent is for configuring a logical network on the node to which the agent is deployed. The method monitors status of the deployed agents. Upon detection that a particular agent on a particular node is no longer operating correctly, the method prevents a container cluster control plane from deploying application resources to the particular node.Type: ApplicationFiled: March 16, 2022Publication date: August 3, 2023Inventors: Qian Sun, Danting Liu, Donghai Han, Wenfeng Liu, Salvatore Orlando

Patent number: 11512976Abstract: The disclosure discloses a latitude-free initial alignment method under a swaying base based on gradient descent optimization. Firstly, swaying base latitude-free alignment is regarded as a Wahba attitude determination problem to inhibit device noise interference, and an objective function is established based on a gravitational acceleration vector under an earth system; then an exact solution of the objective function is obtained through a gradient descent optimization method, and inertial system conversion quaternion estimation is achieved under the latitude-free condition; and finally, an attitude quaternion is determined by only using information of an accelerometer and a gyroscope of a strapdown attitude heading reference system, and therefore latitude-free initial alignment under the swaying base is achieved.Type: GrantFiled: April 21, 2021Date of Patent: November 29, 2022Assignee: HARBIN INSTITUTE OF TECHNOLOGYInventors: Ya Zhang, Qian Sun, Wei Gao, Fei Yu, Yanyan Wang, Xiuwei Xia, Jianxiong Wei, Weiqi Miao
