Patent number: 12050778Abstract: A data restoration method and a related device are provided. To avoid a data loss in a cache in a process of restoring an offline RAID system, a security area is configured in a disk, where the security area is used to back up data in the cache of a RAID controller after the RAID system is offline. Therefore, when a first instruction used to indicate that the RAID system is offline is obtained, the data in the cache may be backed up to the security area. In this way, after the RAID system is restored, the RAID system can obtain backup data of the data in the cache from the security area, to avoid problems such as an operating system startup failure or a user data loss caused by the data loss in the cache.Type: GrantFiled: May 4, 2022Date of Patent: July 30, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Zhifang Cai, Baochen Hou, Zhao Zhou, Ping Zou

Patent number: 12045284Abstract: A method and system provide for searching a computer-aided design (CAD) drawing. A CAD drawing is obtained and includes vector based geometric entities. For each entity, primitives are extracted and held in a graph with graph nodes that record entity paths. A feature coordinate system is created for each of the entities using the primitives. The primitives are transformed from a world coordinate system to feature coordinates of the feature coordinate system. Geometry data of the transformed entities is encoded into index codes that are utilized in an index table as keys with the graph nodes as values. A target geometric entity is identified and a target index code is determined and used to query the index table to identify instances of the target geometric entity in the CAD drawing. Found instances in the CAD drawing are displayed in a visually distinguishable manner.Type: GrantFiled: December 29, 2021Date of Patent: July 23, 2024Assignee: AUTODESK, INC.Inventor: Ping Zou
