  • Patent number: 10693500
    Abstract: Methods and apparatus for the decoding of forward error correction codes. One method includes decoding a number of component codes including code symbols, for which at least one code symbol is involved in multiple component codes, and analyzing the decoding of each of the component codes to generate an outcome. Analyzing the decoding includes estimating at least one possible error location, storing information related to the at least one possible error location; storing state information, and updating the state information.

  • Patent number: 8597167
    Abstract: An apparatus for producing bags made of tube pieces having fabric made of stretched plastic strips and with two material webs lying on top of each other includes a transport device, via which the tube pieces are conveyed in a horizontal position in a transport direction (x) extending transversely to the direction of extension (z) of the tube pieces, a bottom-opening station, via which open bottom squares are produced on at least one end of a tube piece, a closing station, via which the bottoms opened at the bottom-opening station are folded up, and a bottom-patch station, via which a bottom patch is applied for closing the bag bottom. At least one processing station on the operating side (BS) is disposed such that it is at least partly offset to a similar processing station on the drive side (AS).
