  • Patent number: 10998494
    Abstract: Some embodiments of the present disclosure relate to a method that achieves a substantially uniform pattern of magnetic random access memory (MRAM) cells with a minimum dimension below the lower resolution limit of some optical lithography techniques. A copolymer solution comprising first and second polymer species is spin-coated over a heterostructure which resides over a surface of a substrate. The heterostructure comprises first and second ferromagnetic layers which are separated by an insulating layer. The copolymer solution is subjected to self-assembly into a phase-separated material comprising a pattern of micro-domains of the second polymer species within a polymer matrix comprising the first polymer species. The first polymer species is then removed, leaving a pattern of micro-domains of the second polymer species. A pattern of magnetic memory cells within the heterostructure is formed by etching through the heterostructure while utilizing the pattern of micro-domains as a hardmask.

    Abstract: A method and apparatus for video coding using block partition are disclosed. According to the present invention, a partition structure corresponding to recursively partitioning a current block into smaller TU (transform unit) blocks until the partition structure reaches a maximum allowed split depth or until a block size of at least one of smaller TU blocks is a supported core transform size, where the current block is partitioned into final smaller TU blocks according to the partition structure. A transform coding process is applied to the current block according to the partition structure, where the transform coding process is skipped for at least one of the final smaller TU blocks. A flag can be signalled for the current block to indicate whether the current block is allowed to skip the transform coding process for said at least one of the final smaller TU blocks.

  • Publication number: 20210051345
    Abstract: A video coder that implements illumination compensation is provided. The video coder receives a first block of pixels in a first video picture to be coded as a current block, wherein the current block is associated with a motion vector that references a second block of pixels in a second video picture as a reference block. The video coder performs inter-prediction for the current block by using the motion vector to generate a set of motion-compensated pixels for the current block. The video coder modifies the set of motion-compensated pixels of the current block by applying a linear model that is computed based on neighboring samples of the reference block and of the current block. The neighboring samples are identified based on a position of the current block within a larger block.

  • Publication number: 20210014536
    Abstract: In one method, the current block is partitioned into multiple final sub-blocks using one or more stages of sub-tree partition comprising ternary tree partition and at least one other-type partition, where ternary partition tree is excluded from the sub-tree partition if a current sub-tree depth associated with a current sub-block is greater than a first threshold and the first threshold is an integer greater than or equal to 1. In another method, if a test condition is satisfied, the current block is encoded or decoded using a current Inter mode selected from a modified group of Inter tools, where the modified group of Inter tools is derived from an initial group of Inter tools by removing one or more first Inter tools from the initial group of Inter tools, replacing one or more second Inter tools with one or more complexity-reduced Inter tools, or both.

  • Publication number: 20200396444
    Abstract: A method and apparatus for video coding using Intra prediction are disclosed. In one method, a first prediction sample in an immediately right column of the current block and a second prediction sample in an immediately below row of the current block are derived using angular prediction. The first prediction sample and a left column reference sample in the same row as the first prediction sample are interpolated to generate a horizontal predictor. The second prediction sample and an above-row reference sample in the same column as the second prediction sample are interpolated to generate a vertical predictor. The vertical predictor and the horizontal predictor are linearly combined to generate an angular-planar prediction sample. In another method, a first predictor is generated using angular prediction and a second predictor is generated using planar prediction. The first predictor and the second predictor are linearly combined to generate a fused Intra predictor.

  • Patent number: 10832101
    Abstract: The present subject matter describes an electronic card holder. In an example implementation, the electronic card holder includes a housing having a slot to receive an electronic card. A slidable frame in the housing is to hold the electronic card. The slidable frame has a stud fittable in a groove in the housing. The card holder includes a resilient element with one end being coupled to the housing and other end being coupled to the slidable frame. The card holder further includes an actuating member coupled to the groove. When the electronic card is pushed inside the housing, the slidable frame is moved to lock the stud inside the groove and compress the resilient element. When the actuating member is pushed, the stud is released from the groove and the resilient element is relaxed to move the slidable frame such that the electronic card is pushed out of the housing.

    Abstract: A video decoder that implements a mutually exclusive grouping of coding modes is provided. The video decoder receives data for a block of pixels to be decoded as a current block of a current picture of a video. When a first coding mode for the current block is enabled, a second coding mode is disabled for the current block, wherein the first and second coding modes specify different methods for computing an inter-prediction for the current block. The current block is decoded by using an inter-prediction that is computed according to an enabled coding mode.
