  • Patent number: 7760886
    Abstract: For synthesizing at least three output channels using two stereo input channels, the stereo input channels are analyzed to detect signal components occurring in both input channels. A signal generator is operative to introduce at least a part of the detected signal components into the second channel associated with a second speaker in an intended speaker scheme, which is positioned between a first and a third speaker in the speaker scheme. When, however, feeding of the complete detected signal components would result in a clipping situation, then only a part of the detected signal components is fed into the second channel as a real center channel and the remainder is located in the first and third channels as a phantom center channel.

  • Publication number: 20100030563
    Abstract: An apparatus for generating an ambient signal from an audio signal includes a compressor for lossy compression of a representation of the audio signal so as to obtain a compressed representation of the audio signal describing a compressed audio signal. The apparatus for generating the ambient signal further includes a calculator for calculating a difference between the compressed representation of the audio signal and the representation of the audio signal so as to obtain a discrimination representation. The apparatus further includes a provider for providing the ambient signal using the discrimination representation. An apparatus for deriving a multi-channel audio signal from an audio signal includes an apparatus for generating an ambient signal from an audio signal, an apparatus for providing the audio signal as a front-loudspeaker signal and an apparatus for providing the ambient signal as a back-loudspeaker signal.

  • Patent number: 7635126
    Abstract: During the gathering process, an individual signature is respectively withdrawn from several collections of identical signatures, wherein the various decollated signatures are delivered to a collecting conveyor in order to form stacks. In this case, the sheets need to be reliably and carefully decollated. The invention proposes that the sheets (3) of a collection are made available in the form of a stack (4), wherein the stack (4) is essentially supported by an air cushion (LP), that the bottom sheet (3) is at least regionally lifted off the stack (4) with the aid of a separating tool (30), that the air cushion (LP) is produced between the bottom sheet (3) and the residual stack (4), and that the sheet (3) is delivered to the collecting conveyor (10). The lifted-off sheet is completely separated from the stack by the air cushion such that the sheet can be transported out of the magazine with absolutely no friction relative to the stack (4) situated above the separated sheet.

  • Publication number: 20070242833
    Abstract: A transient detector is provided for generating an ambience signal suitable for being emitted via loudspeakers for which there is no special loudspeaker signal to detect a transient period. A synthesis signal generator produces a synthesis signal which fulfils the transient condition on the one hand and the continuity condition for the synthesis signal on the other hand. A signal substituter will then substitute a portion of the examination signal by the synthesis signal to obtain an ambience signal for the surround channels.

  • Publication number: 20070209752
    Abstract: A method and apparatus for feeding a cover (10, 11, 12, 13) in the production of perfect-bound or saddle-stitched books, brochures, magazines or similar printed products (14, 15) featuring an inner part (2) that consists of a collection of folded sections, layers and/or individual sheets and a cover (10, 11, 12, 13) that is placed around the inner part (2) and connected thereto. A roll (3) comprising a wound-up cover web (4) is supplied, the cover web (4) is unwound and a cover sheet (10, 11, 12, 13) with the desired format height is separated from the cover web (4, 8) and fed to the inner part (2) in order to be placed around the inner part and connected thereto. This allows a reliable and flawless feed of the covers to the inner parts, and the operating effort for the cover feed is reduced.
