Patent number: 12373139Abstract: Decoupled computing systems include layers of same-type computing resources, and include a dispatch layer to assign tasks from one layer to another, such as input and output (I/O) flows. The I/O flows can be assigned to particular computing resources of a layer based on a weighted moving average of performance data for the layer. When traffic is high, the assignment can include random assignment to some or all of the computing resources in the layer. The I/O flows can be split between read-intensive and write-intensive flows, with more read-intensive flows being assigned based on a pick ratio.Type: GrantFiled: September 27, 2023Date of Patent: July 29, 2025Assignee: Lemon Inc.Inventors: Zhengyu Yang, Hao Wang, Sheng Qiu, Jianyang Hu, Yang Liu, Yizheng Jiao, Qizhong Mao, Jiaxin Ou, Ming Zhao, Yi Wang, Jingwei Zhang

Publication number: 20250193835Abstract: A positioning method and an apparatus. A terminal is positioned by using a satellite. The information about a plurality of satellite reference points is obtained; time information corresponding to a service satellite is determined; time information corresponding to the plurality of satellite reference points and the time information corresponding to the service satellite are reported to the service satellite; and a position of a terminal device is determined based on the time information corresponding to the service satellite and the time information corresponding to the plurality of satellite reference points. There is no need to actually deploy satellites at the satellite reference points. In addition, in comparison with a single satellite moving to different positions to position the terminal device, a positioning delay is reduced, and positioning accuracy is improved.Type: ApplicationFiled: February 6, 2025Publication date: June 12, 2025Inventors: Ying CHEN, Jingwei ZHANG, Xiaolei TIE

Disclosed systems may include a runtime manager that is in communication with an LLM, and which controls the LLM's execution of the complex task. This control can be defined by a “playbook” that is provided to the LLM, and which contains a series of instructions that are to be followed by the LLM under a desired level of control by the runtime manager. The playbook can take the form of a script containing a sequence of instructions and related conditions that are written in a human-readable, natural-language format.Type: ApplicationFiled: August 22, 2023Publication date: February 27, 2025Inventors: Vladimir Vuskovic, Lukasz Bieniasz-Krzywiec, Jingwei Zhang, Ferdinand Lösch

Patent number: 12235817Abstract: Systems and methods are provided for improved point querying of a database. The index values are separated from data and retained in cache memory to allow access without requiring a disk input/output (I/O) operation and thereby having less latency resulting from such disk I/O operations. The index values can be compressed using an algorithm such as Crit-Bit-Trie to allow storage of the index values in limited cache memory space. The index values can be selected for storage according to a least recently used approach when cache memory is insufficient to store all index values to maintain a hit rate for the cached portion and reduce the disk I/O operations.Type: GrantFiled: September 27, 2023Date of Patent: February 25, 2025Assignees: Beijing Volcano Engine Technology Co., Ltd., Lemon Inc.Inventors: Jiaxin Ou, Jingwei Zhang, Hao Wang, Hui Zhang, Ming Zhao, Yi Wang, Zhengyu Yang

Patent number: 11979506Abstract: In a method for statistical analysis of aggregate encrypted data with key-leakage resilience for smart grids, every user area is managed by a fog node which plays the role of data aggregation gateway and data relay. All the users' electricity consumption data sent by smart meters in the same user area are firstly aggregated by the fog node to generate a fog-level aggregate ciphertext. Then the fog node further generates a digital signature for the fog-level aggregate ciphertext and sends these data to a cloud server for long-time storage. The cloud server stores all the aggregate ciphertexts and digital signatures received from different user areas in its database, and provides data query and statistical analysis services for the control center of smart grids. On the premise of without violating users' privacy, the cloud server could provide enough information for the control center, enabling it to compute the sum, arithmetic mean and variance of all users' data in specified areas in a privacy-preserving way.Type: GrantFiled: July 14, 2020Date of Patent: May 7, 2024Assignee: SOUTHWEST PETROLEUM UNIVERSITYInventors: Xiaojun Zhang, Chao Huang, Jingwei Zhang, Jie Gong, Ziyu Zhou, Shuang Zheng, Jie Zhao
