    摘要: Embodiments of the present invention exploit redundancy of succeeding FFT spectra and use this redundancy for computing interpolated temporal supporting points. An analysis filter bank converts overlapped sequences of an audio (ex. loudspeaker) signal from a time domain to a frequency domain to obtain a time series of short-time loudspeaker spectra. An interpolator temporally interpolates this time series. The interpolation is fed to an echo canceller, which computes an estimated echo spectrum. A microphone analysis filter bank converts overlapped sequences of an audio microphone signal from the time domain to the frequency domain to obtain a time series of short-time microphone spectra. The estimated echo spectrum is subtracted from the microphone spectrum. Further signal enhancement (filtration) may be applied. A synthesis filter bank converts the filtered microphone spectra to the time domain to generate an echo compensated audio microphone signal. Computational complexity of signal processing systems can, therefore, be reduced.

    摘要: A corner cabinet fitting has a support with a guide member supporting a shelf in the cabinet interior for transferring the shelf from an inner position in the cabinet interior into an outer position. The guide member has a first end articulated by a guide member joint axis on the shelf bottom and a second end connected pivotably by a support fitting with a corner cabinet part. During closing, a pull-in device associated with shelf and guide member automatically pulls in shelf and guide member into the cabinet interior from a defined intermediate pivoted shelf position onward. The pull-in device is supported solely on the guide member or the shelf in coaxially alignment with the guide member joint axis on the shelf bottom. An actuator, connected to the pull-in-device and movable relative to the guide member, interacts with a driver on the shelf or on the guide member.

    摘要: The invention relates to a fitting for corner cabinets (1), in particular for kitchen corner cabinets, with an essentially rectangular interior (2) from the top view, which is accessible from the front side via a corner cabinet door (3). Said fitting consists of at least one support which can be supported in a stationary manner in the interior (2) of the corner cabinet, for maintaining at least one single-piece shelf (5) having a semi-circular base shape. Said support comprises at least one guide member (6) which supports the shelf (5) in an articulated manner and moves the shelf (5) on a predetermined movement path from an inner position in the interior (2) of the corner cabinet (1) to an outer position essentially in front of a door opening of corner cabinet (1), which is pivotably connected and in an articulated manner by means of a guide member joint axis to the lower side of the shelf (5) and by means of a support fitting, to a corner cabinet part, in particular a side wall part (4). A pull-in device (11) is associated with the shelf (5) and the guide element (6), for automatically pulling-in the shelf (5) and the guide element (6) into the interior (2) of the corner cabinet (1) from a determinable intermediate pivotable position of the shelf (5) during a closing movement. The aim of the invention is to produce a fitting which enables the shelf to be automatically pulled-in together with the guide element from a predeterminable intermediate position in a simple manner. Said pull-in device (11) is supported by itself on the guide element (6) and has a joint axis which is coaxial to the guide element joint axis on the lower side of the shelf (5), and comprises an adjusting device (15) which interacts with a drive device (10) provided on the shelf and can be moved in relation to the guide element (6).
