  • Patent number: 12273581
    Abstract: The present disclosure relates to methods and devices for testing video data being rendered at or using a media device. A plurality of video frames to be rendered is received, each frame comprising one or more primary screen objects and at least one further screen object. The received frames are rendered at or using the media device wherein the at least one further screen object is superimposed on the one or more primary screen objects of a given frame during rendering. The rendered frames are provided to a data model. Extracted metadata indicating the presence or absence of further screen objects in the rendered video frames is the output of the data model. The data model is also provided with original metadata associated with the video frames prior to rendering. The rendering of each further screen object is then tested based on the original metadata and extracted metadata relating to a given video frame.

  • Publication number: 20250025471
    Abstract: Disclosed are a pharmaceutical composition, an aprepitant injection, and an aprepitant freeze-dried powder injection. The pharmaceutical composition comprises aprepitant, a primary stabilizer, and a secondary stabilizer, wherein the primary stabilizer comprises sodium deoxycholate and the secondary stabilizer comprises povidone. The aprepitant injection can be administered by injecting. The formulation uses a largely reduced amount of excipients, and is less irritative to an injection site, less prone to cause a hypersensitive reaction, and thus safer when being used by a patient. The formulation has good stability and can be stored and transported at room temperature, largely reducing production, storage, and transportation costs.

  • Publication number: 20250021605
    Abstract: 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. 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 a feature coordinate system. Geometry data of the transformed entities is encoded into index codes that are utilized in an index table as keys. 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.

  • Patent number: 12050778
    Abstract: 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.

  • Patent number: 12045284
    Abstract: 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.
