  • Patent number: 11216049
    Abstract: A bus system is provided. The bus system includes a master device and a plurality of slave devices electrically connected to the master device. Each slave device has an alert handshake pin. The alert handshake pins of the slave devices are electrically connected together via an alert handshake control line. When the alert handshake control line is at a first voltage level and a first slave device want to communicate with the master device, the first slave device controls the alert handshake control line to a second voltage level via the alert handshake pin, such that the slave devices enter a synchronization stage. Among phases of each assignment period, in a first phase corresponding to the first slave device, the first slave device controls the alert handshake control line to the second voltage level via the alert handshake pin.

  • Patent number: 11212523
    Abstract: Video processing methods and apparatuses include receiving input video data, determining a Merge number for a regular Merge mode, comparing the Merge number for the regular Merge mode with a predefined value, and only signaling or parsing a difference between the Merge number for the regular Merge mode and a Merge number for a Geometric Partition Mode (GPM) Merge mode when the Merge number for the regular Merge mode is larger than or equal to the predefined value. The difference between the Merge numbers is inferred to 0 when the difference is not signaled. The Merge number for the GPM Merge mode defines a size of a GPM Merge candidate list constructed for each block coded or to be coded by the GPM Merge mode.

  • Publication number: 20150274909
    Abstract: To produce an anti-flame film, nanoscale silicate platelets (NSP) are first diluted with water or an organic solvent; the dispersion is then dried on a surface to remove the water or organic solvent and finally an almost inorganic and flexible film with a thickness of 1 to 1,000 ?m is obtained. The film has a regularly layered alignment of primary platelet (1 nm thickness) structure. The NSP film has excellent anti-flame and heat insulation properties that can effectively shield a flame of more than 800° C. without apparent deformation in shape. The NSP can be blended with polymers with a composition over 30% or preferably 70% of NSP to make composite films with significant improvement in flame and heat shielding.
