  • Publication number: 20210360255
    Abstract: A video coder receives data from a bitstream for a block of pixels to be encoded or decoded as a current block of a current picture of a video. Upon determining that an applied block setting of the current block satisfies a threshold condition, the video coder generates a first prediction based on a first motion information for a first prediction unit of the current block. The video coder generates a second prediction based on a second motion information for a second prediction unit of the current block. The video coder generates a third prediction based on the first and second motion information for an overlap prediction region that is defined based on a partitioning between the first prediction unit and the second prediction unit. The video coder encodes or decodes the current block by using the first, second, and third predictions.

  • Patent number: 11173561
    Abstract: The present application discloses a method for processing probe. Firstly, a clamping member of a rotation shaft is clamped with a workpiece, and then the workpiece is moved to a processed area by the rotation shaft. The workpiece is rotated by the rotation shaft, and an electrochemical process of the workpiece is performed under the rotation of the shaft and an electrolyte sprayed between the workpiece and the polished module. During the performing of the electrochemical process, it can be that the rotation shaft is moved a processing distance or the included angle of the polish module is changed, for a probe being accomplished from the workpiece. Thereby, the abrasion of the polish module is lower and the performance for processing the probe under the electrochemical process.

  • Patent number: 11166292
    Abstract: Methods and apparatuses for handling collision between sidelink feedback and sidelink data in a wireless communication system are disclosed herein. In one method, a User Equipment (UE) is (pre-)configured to perform one or more sidelink transmissions on multiple carriers, wherein the UE is able to transmit a first number of carriers among the multiple carriers at the same time. The UE selects a first resource for transmitting a first sidelink transmission in a first slot on a first carrier. The UE derives a second resource for transmitting a PSFCH delivering a feedback in a second slot on a second carrier, wherein the second slot is at least partly overlapping with the first slot in a time domain. The UE determines whether to prioritize either the PSFCH or the first sidelink transmission based on a rule when the number of carriers which the UE identifies to transmit in the overlapped slot exceeds the first number of carriers.
