  • Textile Filter System, Method For Regenerating A Textile Filter and Regeneration Apparatus
    Publication number: 20140246055
    Abstract: A textile filter system of a pulse jet filtration device that includes a particulate textile filter bag to restrain particles in a gas stream and a textile, chemically active filter sleeve to remove substances from the gas stream. For regenerating a chemically active textile filter, the filter is removed from the filtration device and washed in water along with mechanically treating the textile filter.

  • Method for recovering information from channel-coded data streams
    Patent number: 7725798
    Abstract: A method and system for recovering useful information, in particular useful information transmitted in digital form on terrestrial or satellite-based information paths, for example as voice, image or data signal, from channel-coded data streams encoded with turbo codes with a predefined code rate is disclosed. The data streams are received by a turbo decoder with a presettable number of decoder components and subsequently decoded in an iterative process according to the MAP and/or Max-Log-MAP standard. The iterative process is controlled by a stop criterion, wherein after termination of the iterative process in the turbo decoder at least one of the decoder components, in particular the associated lattice diagram, is used for an additional decoding process that is different from the MAP and/or Max-Log-MAP standard. This approach lowers the error floor of the turbo code.
