  • Publication number: 20230067126
    Abstract: The present invention includes a reference parallel line creation step of creating a pair of parallel lines that are respectively in contact with outer edges of a workpiece cross-section without traversing the workpiece cross-section and that are located on an extension plane of the workpiece cross-section, a first determination step of comparing a width between the pair of parallel lines that have been created in the reference parallel line creation step with a maximum separation threshold of the welding electrodes, and determining whether the maximum separation threshold is larger than the width between the parallel lines, and a pull-out direction determination step of determining a direction of the parallel lines as a pull-out direction, in a case where the maximum separation threshold is larger than the width between the parallel lines in the first determination step.

  • Patent number: 11593968
    Abstract: In some embodiments, a method analyzing a first set of values for a first bin plane in a plurality of bin planes. The plurality of bin planes are used to determine a context model for entropy coding of a current block in a video. The method determines whether to use a second set of values from a second bin plane based on the analyzing. When it is determined to use the second set of values, information is calculated for the context model using the first set of values and the second set of values. When it is determined to not use the second set of values, information is calculated for the context model using the first set of values.

  • Patent number: 11496809
    Abstract: In some embodiments, a method receives a first set of video files at a node that delivers video files to client devices and receives a second set of video files. The second set of video files are predicted to be delivered by the node to a client device during a time period. The node receives a request for a video file from a client device and determines whether the video file is stored in the first set of video files and the second set of video files. When the video file is stored at the node, the node sends the video file from the first set of video files and the second set of video files. When the video file is not stored in the first set of video files and the second set of video files, the node sends a request for the video file to another node.
