    摘要： A method for protecting at least a part of a network segment of an electrical power distribution network has: detecting voltage dips at the intermediate feeding devices of the line arrangements by the voltage dip detection devices; generating and feeding an electrical signal into the line arrangement by the signal generating device at each intermediate feeding device at which one of the voltage dips is detected, the electrical signals having frequencies different from a network frequency of the network segment; receiving the electrical signals via the line arrangements by the receiving devices of the line protection devices; detecting electrical faults on the line arrangement using the electrical signals received by the triggering device of the respective line protection device; and triggering the disconnecting device of the line protection device of the line arrangement, where an electric fault is detected, by the triggering device so that the line arrangement is electrically disconnected from the further element.

    摘要： An apparatus includes a comparator circuit and a clock generation circuit. The comparator circuit is configured to compare a first input signal with a second input signal during a first comparison phase to obtain a comparison result. Furthermore, an output signal is output, wherein a waveform of the output signal indicates the comparison result. During a subsequent regeneration phase, at least a part of the comparator circuit is reset for a subsequent second comparison phase. The comparator circuit is configured to receive a clock signal, and to change from the first comparison phase to the regeneration phase based on the clock signal. The clock generation circuit is configured to receive the output signal or a signal derived therefrom, and to generate the clock signal based on the waveform of the output signal to control the comparator circuit from the comparison phase to the regeneration phase based on the signal waveform.

    摘要： There are disclosed apparatus and methods for encoding and decoding of acoustic environment.
    In accordance with an example, there is provided an apparatus for decoding an acoustic environment, the acoustic environment including at least one audio source and at least one audio object, the at least one audio object being represented by a structural-acoustic data which links positional data of polygons with acoustic properties of acoustic materials, wherein the positional data includes, for each polygon, the position of the vertexes, the apparatus comprising:



    a bitstream reader for reading, from the bitstream, an encoded version of structural-acoustic data and at least one audio stream to be rendered as generated by the at least one audio source in the acoustic environment;
    an audio source decoding block to decode the at least one an audio stream representing the at least one audio source;
    a structural-acoustic data decoding block to decode the structural-acoustic data.
