  • Patent number: 8392184
    Abstract: The invention relates to speech signal processing that detects a speech signal from more than one microphone and obtains microphone signals that are processed by a beamformer to obtain a beamformed signal that is post-filtered signal with a filter that employs adaptable filter weights to obtain an enhanced beamformed signal with the post-filter adapting the filter weights with previously learned filter weights.

  • Patent number: 7937925
    Abstract: A drive chain suitable for use in a continuously variable transmission of a motor vehicle, the transmission having two pairs of spaced drive members about which the chain passes to transfer torque from one drive member to the other. The chain includes a plurality of link elements that include spaced, side-by-side plate links. The plate links include openings in which pairs of parallel rocker members are disposed for relative rocking movement of at least one rocker member about its longitudinal axis. A method for stretching the chain is also disclosed, in which areas of some of the plate links are plastically deformed by stretching the chain before the chain is put to use.

  • Patent number: 7048657
    Abstract: A transmission with a drive side and an output side conical disk pair. One conical disk pair includes a fixed disk carried by a shaft, a movable disk non-rotatably connected with and axially movable relative to the shaft, and a support ring axially attached to the shaft adjacent a back side of the movable disk. A pressure chamber between the support ring and the back side of the movable disk is supplied with hydraulic pressure medium through a passage in the shaft that opens to the surface of the shaft. An end region of the movable disk when moved along the shaft passes over the opening at a maximum spacing of the movable disk from the fixed disk, and a hydraulic medium connection exists between the passage and the pressure chamber through drainage slots between an inner surface of the movable disk and the peripheral surface of the shaft.

  • Patent number: 6293887
    Abstract: A plate link chain of the present invention has rocker link elements configured such that the frictional end surfaces have a profile, which deviates from a planar surface in both circumferential and radial orientations. In a preferred embodiment the end surface profiles are defined by radii of predetermined dimensions in the range of 5 to 50 millimeters with the radius formed in the radial plane being larger than the radius formed in the circumferential plane. The radii originate from midpoints, which are located at predetermined distances from the rocking surfaces, to form substantially spherical end surfaces that are either symmetric or asymmetric for selected applications. The substantially spherical end surfaces are designed to reduce the edge transfer forces and tracking error of the rocker link elements and to improve wear characteristics and the stability of frictional engagement of the transmission in operation.
