  • Publication number: 20230088154
    Abstract: In accordance with a first aspect, the intra prediction direction of a neighboring, intra-predicted block is used in order to predict the extension direction of the wedgelet separation line of a current block, thereby reducing the side information rate necessitated in order to convey the partitioning information. In accordance with a second aspect, the idea is that previously reconstructed samples, i.e. reconstructed values of blocks preceding the current block in accordance with the coding/decoding order allow for at least a prediction of a correct placement of a starting point of the wedgelet separation line, namely by placing the starting point of the wedgelet separation line at a position of a maximum change between consecutive ones of a sequence of reconstructed values of samples of a line of samples extending adjacent to the current block along a circumference thereof. Both aspects may be used individually or in combination.

  • Patent number: 9806738
    Abstract: Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VLC coding and with at least one by PIPE or entropy coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, syntax elements are decomposed into a respective number n of source symbols si with i=1 . . . n, the respective number n of source symbols depending on as to which of a sequence of n partitions into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols si yields z, and, if n>1, for all i=1 . . . n?1, the value of si corresponds to a range of the ith partition.

  • Publication number: 20170219047
    Abstract: A torsional vibration damping arrangement includes: an input region, an output region, and a coupling arrangement communicating with the output region. A phase shifter arrangement communicates with the input region. A torque transmission path extending between the input region and the output region transmits a total torque. The torque transmission path is divided into first and second torque transmission paths, which paths are guided back together again at the coupling arrangement. An input torsional vibration is divided into two torsional vibration components by being conducted respectively via the first and second torque transmission paths and are destructively superimposed at the coupling arrangement to form a minimized output torsional vibration relative to the input torsional vibration. A planet wheel carrier is constructed as a modular building block planet carrier element and includes at least a first connection area.

    Abstract: A torsional vibration damping arrangement for transmitting a rotation from an input side to an output side includes a first and second torque transmission path arranged between the input side and the output side. A coupling arrangement serves to superpose the first torque component and second torque component. A phase shifter arrangement serves to generate a phase shift between torsional vibrations which are transmitted to the coupling arrangement via the first and second torque transmission paths, wherein the phase shifter arrangement comprises an oscillatory system with a primary side coupled with the input side and a secondary side which is rotatable with respect to the primary side and which is connected to the coupling arrangement. An effective mass moment of inertia of the secondary side inhibiting a change in a rotational velocity of the secondary side is dependent upon the rotational velocity.

  • Publication number: 20090098944
    Abstract: The invention is directed to a disk for the transmission of a torque in a torque transmission device of a motor vehicle. The disk has a radial inner area that can be connected to a first structural component part, a radial outer area that can be connected to a second structural component part, and a quantity of bore holes for the passage of fastening elements for connecting the radial outer area to the second structural component part. In the area between the radial inner area and the radial outer area, the disk has an offset that offsets the two areas relative to one another in axial direction. To employ a long-lasting rivet connection for fastening the disk in an economical manner, the invention incorporates at least one recess in the disk in the area of the offset.
