  • Publication number: 20230011977
    Abstract: A dynamically-reconfigurable power converter includes a controller circuit and switching circuitry. The switching circuitry includes a first set of nodes electrically connectable to terminals of an energy storage device, a second set of nodes electrically connectable to at least one winding of a rotational electric machine, and a third set of nodes electrically connectable to an external power source. Electrical measurement circuitry monitors electrical conditions at the first set of nodes and the third set of nodes. The switching circuitry is operative in a first mode to regulate power delivery from the first set of nodes to the second set of nodes, and in a second mode to regulate power delivery between the third set of nodes and the first set of nodes via the second set of nodes.

  • Publication number: 20220416810
    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.

  • Patent number: 11533486
    Abstract: The coding of a media signal is rendered more efficient by describing the media signal using a sequence of samples and sequentially encoding this sequence by selecting, for a current sample, a set of quantization levels out of a plurality of quantization level sets depending on indices encoded into the data stream for previous samples of the sequence of samples, quantizing the current sample onto one level of the set of quantization levels, and encoding a quantization index to the one level for the current sample into the data stream. In other words, scalar quantization of the individual samples of the sequence of samples is used, but it is rendered dependent on quantization indices encoded into the data stream for previous samples of the sequence of samples.

  • Patent number: 11533485
    Abstract: An entropy decoder is configured to, for horizontal and vertical components of motion vector differences, derive a truncated unary code from the data stream using context-adaptive binary entropy decoding with exactly one context per bin position of the truncated unary code, which is common for horizontal and vertical components of the motion vector differences, and an Exp-Golomb code using a constant equi-probability bypass mode to obtain the binarizations of the motion vector differences. A desymbolizer is configured to debinarize the binarizations of the motion vector difference syntax elements to obtain integer values of the horizontal and vertical components of the motion vector differences. A reconstructor is configured to reconstruct a video based on the integer values of the horizontal and vertical components of the motion vector differences.

  • Publication number: 20220321886
    Abstract: A decoder configured to decode residual levels, and sequentially dequantize the residual levels by selecting a quantizer out of a set of default quantizers depending on a current transition state, and updating the current transition state depending on a current residual level's characteristic obtained by an application of a binary function onto the current residual level, and depending on a quantization mode information contained in the data stream. The current transition state transitions, according to a surjective mapping which depends on the quantization mode information, from a domain of combinations of a set of one or more transition states with the current residual level's characteristic onto the set of one or more transition states, wherein a cardinality of the set of one or more transition states differs depending on the quantization mode information.

  • Publication number: 20220140478
    Abstract: A reference signal generator (1) generates a reference signal (REF) having high auto-correlation. A delay unit (2) delays the reference signal (REF) to generate delayed reference signals and outputs the reference signal (REF) and the delayed reference signals to the transmission units (TR1-TRN), respectively. A calibration network (3) combines the output signals of the transmission units (TR1-TRN). An analyzer (4) analyzes a correlation between a demodulated signal (DEM) and the reference signal (REF) 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.

  • Patent number: 11297336
    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.
