  • Publication number: 20240247918
    Abstract: An arrangement has an opto-pyrotechnic initiator, at least one laser, and an optical fibre, via which the laser radiation of the laser is guided to the opto-pyrotechnic initiator. Also disclosed is a method for improving the safety of such an opto-pyrotechnic initiator. At least one optical filter element having power-dependent or intensity-dependent transmission or reflection is arranged in the beam path of the laser radiation between the laser and the initiating impingement location of the laser radiation in the initiator. The filter element and the beam guidance for the laser radiation are selected such that for a laser power of the laser, that is intended to effect an initiation, the filter element has a higher transmission or reflection or can be switched to a higher transmission or reflection than for a lower laser power by application of an optical or electronic signal that is independent of the laser radiation.

  • Patent number: 12041228
    Abstract: Apparatus configured to derive a set-selective syntax element indicating whether the predetermined block is to be predicted using one of a first set of intra-prediction modes comprising a DC intra prediction mode and angular prediction modes.

If the set-selective syntax element indicates that the predetermined block is not to be predicted using one of the first set of intra-prediction modes, the apparatus is configured to use a matrix-based intra-prediction mode. The list of most probable intra-prediction modes is formed such that the list of most probable intra-prediction modes is free of the DC intra prediction mode in case of the neighbouring blocks being predicted by any of the angular intra prediction modes.

  • Patent number: 12034928
    Abstract: Decoder for decoding a transformed representation of a sample block from a data stream. If a first coded coefficient is located inside a predetermined subarea of the transform coefficient block and if the underlying transform is within a first set of available transforms, the decoder decodes coefficients along a first coefficient scan order. If the transform is within a second set of In available transforms, the decoder decodes coefficients located within the predetermined subarea along a second coefficient scan order, and infers that coefficients located outside the predetermined subarea are zero. The first coefficient scan order is so that coefficients outside the predetermined subarea are scanned between two transform coefficients located inside the predetermined subarea. The second coefficient scan order does not scan any coefficient outside the predetermined subarea between scanning the coefficients within the predetermined subarea.
