摘要： An apparatus for estimating an inter-channel time difference between a first channel signal and a second channel signal, includes a signal analyzer for estimating a signal characteristic of the first channel signal or the second channel signal or both signals or a signal derived from the first channel signal or the second channel signal; a calculator for calculating a cross-correlation spectrum for a time block from the first channel signal in the time block and the second channel signal in the time block; a weighter for weighting a smoothed or non-smoothed cross-correlation spectrum to obtain a weighted cross correlation spectrum using a first weighting procedure or using a second weighting procedure depending on a signal characteristic estimated by the signal analyzer, wherein the first weighting procedure is different from the second weighting procedure; and a processor for processing the weighted cross-correlation spectrum to obtain the inter-channel time difference.

摘要： There are disclosed techniques for puncturing and/or overlaying transmission in case of necessity of on-demand (e.g., urgent) commutations. In particular, transceivers, user equipments, systems, methods and non-transitory storage units are disclosed. For example, there is disclosed a transceiver of a wireless communication network, wherein the transceiver is configured to operate in a puncturing mode by puncturing a downlink, DL, transmission of payload information in a channel originally allocated to the DL transmission of payload information, to obtain, within the originally allocated channel for the DL transmission of payload information, a DL free area for an uplink, UL, transmission of a user equipment, UE, of the wireless communication network.

摘要： Described and illustrated is a washing machine for washing textiles, including a tub for receiving a washing liquid, a laundry drum inserted at least partially into the tub, a drive for rotating the laundry drum in the tub and a discharge line connected to the tub for discharging washing liquid from the tub. In order to be able to separate the microplastic fibres more easily, cost-effectively and reliably from the washing water or another washing liquid, it is provided that an intermediate storage device is provided for temporarily storing washing liquid discharged via the discharge line, a centrifuge unit rotated by the drive together with the laundry drum for separating microplastic fibres and a return line for transferring the washing liquid from the intermediate storage device into the centrifuge unit.

摘要： The present invention relates to a specific method step (channel hole etching) in the production of a three-dimensionally integrated semiconductor memory. According to the invention, this method step is characterized in that the vertical channel structure to be generated thereby, the so-called channel hole, is generated by applying an anodic etching method. Thereby, layer stacks having significantly more individual layers than in conventional technology can be processed. Accordingly, the number of individual layers within a layer stack to be processed can be increased, whereby the memory capacity of the layer stack can also be increased significantly.
