  • DATA PACKER FOR PACKING AND ALIGNING WRITE DATA
    Publication number: 20120147019
    Abstract: A data packer of an input/output hub of a computer system packs and formats write data that is supplied to it before the write data is written into a memory unit of the computer system. More particularly, the data packer accumulates write data received from lower bandwidth clients for delivery to a high bandwidth memory interface. Also, the data packer aligns the write data, so that when the write data is read out from the write data packer, no further alignment is needed.

    Publication number: 20120114036
    Abstract: The present invention relates to method and apparatus for multiview video coding. In particular, the present invention describes a disparity compensated prediction to exploit the inter-view correlation in multiview video coding by providing stretching, compression, and shearing (SCSH) disparity compensation to approximate the actual disparity effects in addition to the translational disparity. A sub-sampled block-matching disparity estimation technique is provided to implement the SCSH disparity compensation which makes use of the interpolated reference frames for subpixel motion and disparity estimation in conventional hybrid video coding structure.

  • Metal-induced crystallization of amorphous silicon, polycrystalline silicon thin films produced thereby and thin film transistors produced therefrom
    Patent number: 8088676
    Abstract: Crystallization-inducing metal elements are introduced onto an amorphous silicon thin film. A first, low-temperature, heat-treatment induces nucleation of metal-induced crystallization (MIC), resulting in the formation of small polycrystalline silicon “islands”. A metal-gettering layer is formed on the resulting partially crystallized thin film. A second, low-temperature, heat-treatment completes the MIC process, whilst gettering metal elements from the partially crystallized thin film. The process results in the desired polycrystalline silicon thin film.

  • Grease gun
    Patent number: 7997456
    Abstract: An apparatus converts rotary motion of a motor drive shaft into oscillatory motion of a work piece, for example, in a power tool. The apparatus comprises a planetary gear assembly connected to the motor for rotating an output gear. The output gear meshes with a drive gear including a drive pin. The drive pin fits in a yoke slot for reciprocation of the yoke upon rotation of the drive gear. The yoke is operatively connected to the work piece. An air flow system cools the power tool housing. The housing has an inlet aperture in the handle portion and an outlet aperture for placing the interior of the housing in communication with the atmosphere. A wall integral with the handle portion engages the body of the motor housing between a first end and openings in the body. The wall provides a barrier to minimize air flow between an intake air portion of the interior of the housing and an exhaust air portion.
