  • Publication number: 20240200371
    Abstract: The ANGULAR ROTATION LOCKING MECHANISM (ARLM) is used on cargo transport vehicles such as trucks and ships. The structure has a large load capacity, the ability to open and close easily, flexibly, but ensures the ability to lock the brake during the transport of the vehicle, in all weather conditions. Because of a purely mechanical structure, the maintenance and repair process is simple. The main point of the design is the self-positioning between the front pedestal shaft and the locking blade during operation.

  • Patent number: 12003723
    Abstract: A picture in a data stream is subdivided into different size transform bocks. For a transform block, a transformation is selected by checking whether the block's size exceeds a threshold. If it does, a default technique is used to select the transformation. If it does not, a transformation is used from a list of transformations as identified by an index, the list including an identity transformation and non-identity transformations. A coefficients block in the data stream is decoded, and if the selected transformation is the identity transformation, then the coefficients block is used as a residual sample array, and if the selected transformation is not the identity transformation, the coefficients block is subjected to an inverse transformation corresponding to the selected transformation to obtain a residual sample array used to correct a prediction for the transform block.

  • Patent number: 11968395
    Abstract: An idea used herein is to use the same function for the dependency of the context and the dependency of the symbolization parameter on previously coded/decoded transform coefficients. Using the same function—with varying function parameter—may even be used with respect to different transform block sizes and/or frequency portions of the transform blocks in case of the transform coefficients being spatially arranged in transform blocks. A further variant of this idea is to use the same function for the dependency of a symbolization parameter on previously coded/decoded transform coefficients for different sizes of the current transform coefficient's transform block, different information component types of the current transform coefficient's transform block and/or different frequency portions the current transform coefficient is located within the transform block.

  • Patent number: 11968175
    Abstract: A method of filtering a URL against a blacklist includes receiving at least a portion of a Uniform Resource Locator (URL), and determining which of a plurality of XOR filters is applicable to the received at least a portion of a URL, where each of the plurality of XOR filters represents a different portion of a URL blacklist. At least a portion of a URL is forwarded to the applicable one of the plurality of XOR filters, and the at least a portion of the URL is processed in the applicable one of the plurality of XOR filters to produce an output indicating whether the URL is likely on the blacklist.

  • Patent number: 11909127
    Abstract: A reference signal generator generates a reference signal having high auto-correlation. A delay unit delays the reference signal to generate delayed reference signals and outputs the reference signal and the delayed reference signals to the transmission units, respectively. A calibration network combines the output signals of the transmission units. An analyzer analyzes a correlation between a demodulated signal and the reference signal to determine variations of timing, amplitude and a phase of the output signal of each transmission unit. Each transmission unit calibrates the timing, amplitude and phase of the output signal based on a corresponding determination result.

  • Publication number: 20240048705
    Abstract: A video encoder is configured to entropy encode an absolute value of a quantization level of a current transform coefficient at position (xC, yC), wherein the absolute value is encoded using context adaptive binary arithmetic encoding of bins of a first binarization. The video coder is further configured, for the current transform coefficient, to encode a bin of the first binarization by using a context which is determined based on a sum of minimum absolute values of transform coefficient quantization levels, based on encoded bins of the first binarization, at one or more transform coefficient positions among (xC+1, yC), (xC+2, yC), (xC+1, yC+1), (xC, yC+1), and (xC, yC+2).

  • Publication number: 20240031585
    Abstract: A higher coding efficiency for coding a significance map indicating positions of significant transform coefficients within a transform coefficient block is achieved by the scan order by which the sequentially extracted syntax elements indicating, for associated positions within the transform coefficient block, as to whether at the respective position a significant or insignificant transform coefficient is situated, are sequentially associated to the positions of the transform coefficient block, among the positions of the transform coefficient block depends on the positions of the significant transform coefficients indicated by previously associated syntax elements. Alternatively, the first-type elements may be context-adaptively entropy decoded using contexts which are individually selected for each of the syntax elements dependent on a number of significant transform coefficients in a neighborhood of the respective syntax element, indicated as being significant by any of the preceding syntax elements.

  • Publication number: 20230388496
    Abstract: An apparatus for decoding a picture is configured to partition the picture into coding blocks, using recursive multi-tree splitting. Splitting schemes for the multi-tree splitting are described. According to an embodiment, the decoder decodes a split direction flag from a data stream by context adaptive entropy decoding using a context which depends on whether, and discriminates between, a first number of criteria which would be fulfilled in case of a split direction indicated by the split direction flag being horizontal equals a second number of criteria which would be fulfilled in case of the split direction indicated by the split direction flag being vertical, the first number being greater than the second number, and the first number being smaller than the second number.
