    摘要： An improved Braille erasure mechanism may comprise a reverse-embosser or impressing mechanism to imprint a negative Braille cell. A negative Braille cell is the reverse of a normal Braille cell, with one or more dots lowered or pressed into the printing medium in an opposite direction to the raised dots of a normal Braille cell. Because the dots of a negative Braille cell are lowered past the surface of the printing medium, they may be ordinarily undetectable to the fingers of a Braille user. Accordingly, by imprinting a full negative Braille cell on top of a Braille cell to be erased, all of the previously raised dots of the Braille cell may be lowered beyond the surface of the printing medium. Any further Braille cell embossed over the erased cell will be free from corruption, because any dot not used by the new cell will remain lowered and undetectable.

    摘要： In a clip for fastening to a strip or rib, in particular on a motor vehicle, having a single-piece body made of plastic that has a retaining region, the retaining region has a receiving slot with an insertion opening and a locking finger. The locking finger is attached to a first guide section and extends from its fastening end in the insertion direction and in the direction of a second guide section. The locking finger has an insert that forms a tongue projecting from the free end of the locking finger.

    摘要： A method and device is provided for the detection of data symbols contained in a received radio signal, whereby each data symbol is allocated transmit-side a symbol value-specific PN sequence of successive PN chips in the chip clock and the PN sequences allocated to the data symbols are offset QPSK modulated. The method of the invention for incoherent detection provides for converting the received radio signal into a complex baseband signal sampled in the chip clock, generating a demodulated signal by differential demodulation of the complex baseband signal sampled in the chip clock, providing the derived sequences, calculating correlation results by correlating the demodulated signal with the derived sequences, and deriving, i.e., detecting, the values of the data symbols by evaluating the correlation results. In this case, each derived sequence is assigned to a PN sequence allocable transmit-side and includes derived chips, whose values in each case correspond to a logic linking of particular PN chips of the PN sequence allocable transmit-side that is assigned the derived sequence. The invention relates furthermore to a corresponding receiving unit.
