Publication number: 20260192279Abstract: A catalyst shaped body has a column body extending in a longitudinal direction. Its cross section has a central through hole, at least four first corners and a same number of first recesses. The first corners are arranged at the same angular intervals in a circumferential direction to define a first circumscribed circle of an outer contour of the catalyst shaped body, each first corner is tangent to the first circumscribed circle. The first corners and the first recesses are alternately arranged in the circumferential direction. The first corners are an outwardly convex part of a first ellipse, and the first recesses are inwardly concave arcs tangent to the two adjacent first corners, so as to avoid bite between the first corners and/or the first recesses of the catalyst shaped body and the first recesses and/or the first corners of adjacent catalyst shaped bodies.Type: ApplicationFiled: July 4, 2023Publication date: July 9, 2026Inventors: Kai QIAO, Xia ZHANG, Haibo WANG, Lianke GOU, Lanpeng LI

Publication number: 20260187074Abstract: Techniques are disclosed for enabling cross-graph querying in graph databases using a transition operator within a traversal context. In some embodiments, a computing system receives a query containing a transition operator that facilitates transitioning from a first graph to a second graph. The system processes a traversal operation within the first graph, retrieves intermediary data, and transitions to the second graph to perform subsequent traversal operations. The query engine can utilize confidence scores associated with edges in the graphs to filter or prioritize results, ensuring the reliability of returned data. Additionally, data validation techniques using a mirror graph are disclosed, where new data is validated before integration into a production graph. These techniques streamline cross-graph data analysis, improve query efficiency, and maintain graph database integrity while supporting applications such as fraud detection, recommendation systems, and account linking.Type: ApplicationFiled: February 18, 2025Publication date: July 2, 2026Inventors: Junshi Guo, Pengshan Zhang, Xia Zhang, Kasiviswanathan Natarajan, Karteek Reddy Chada, Yu Zhang

Publication number: 20260138487Abstract: An embodiment of the present application provides a battery charging method, an electronic device, and an electric device. The charging method provided by the present application performs alternate charge and discharge cycles with high and low currents during the fast-charging-cycle process, which can eliminate polarization caused by high-current fast charging with only a slight increase in charging duration, improve interface lithium plating, prevent abnormal battery cell voltage plunging phenomena, and balance regional SOC differences at the interface caused by fast charging. Furthermore, low-current charging can reduce temperature rise differences within the battery cell, reduce regional overcharging and over-discharging phenomena, improve lithium plating, and also enhance the usable life of the battery, solving the problem that the existing charging method cannot improve lithium plating on the negative electrode of lithium batteries while ensuring fast charging performance.Type: ApplicationFiled: January 20, 2026Publication date: May 21, 2026Applicant: SUNWODA MOBILITY ENERGY TECHNOLOGY CO., LTD.Inventors: Xia ZHANG, Xingyu TANG, Dengjun AI

Patent number: 12632450Abstract: Techniques are disclosed relating to improving the efficiency of geolocation queries via geospatial cells and query parameter caching. In various embodiments, a system receives a request from a user device to access geolocation information of entities and determine a first geographic location of the device. The system identifies that the first location is within a geospatial cell stored in a database cache and determines whether query parameters corresponding to the cell are stored in the cache. The system may retrieve the cached query parameters corresponding to the geospatial cell and execute a geolocation query on a database storing location information for different entities based on the cached query parameters. Results of the geolocation query may be different from query results of one or more other queries executed, based on the cached query parameters, for other user computing devices located within the given geospatial cell based on the cached query parameters.Type: GrantFiled: February 28, 2024Date of Patent: May 19, 2026Assignee: PayPal, Inc.Inventors: Ying Yue, Xia Zhang, Yu Zhang, Junshi Guo
