    摘要： A method is described for digital transmission of information over copper lines wherein digital signals are precoded by a fixed precoder on a transmitter side and are recovered by blind equalization on a receiver side. The blind equalization is subdivided into an equalization of the magnitude and a subsequent equalization of the phase.

    摘要： An electromagnetic radiation source, such as an arc lamp, is located at a point displaced from the optical axis of a concave toroidal reflecting surface. The concave primary reflector focuses the radiation from the source at an off-axis image point that is displaced from the optical axis. The use of a toroidal reflecting surface enhances the collection efficiency into a small target, such as an optical fiber, relative to a spherical reflecting surface by substantially reducing aberrations caused by the off-axis geometry. A second concave reflector is placed opposite to the first reflector to enhance further the total flux collected by a small target. In accordance with one embodiment, the present invention is directed to devices in which the square of the off-axis distance divided by the radius of curvature is equal to or less than the extent of the source of electromagnetic radiation (y02/r≦s0).

    摘要： The present invention proposes a power train and the operation thereof, suitable for automated actuation of a transmission shiftable between a plurality of gears with a torque transmitting system being actuated automatically at least during a gear change, at least one actuating element operable by at least one drive unit and at least one actuatable shift element being disposed at the transmission side. The invention provides a power train in which a driving connection is disposed between at least one actuatable shift element associated with the transmission and an actuator having at least one drive unit, and at least one presettable elastic means is provided in the power transmitting path of the driving connection between the drive unit and the at least one shift element. Further, at least one additional presettable elastic element can be disposed in the power transmitting path between the at least one actuating element and the at least one shift element on the transmission side.

    摘要： There is disclosed a system for controlling creeping movements of a motor vehicle having a power train with an automated clutch between the engine and the transmission, an electronic control unit for the clutch, and sensors which transmit to the control unit signals denoting the condition of one or more brakes, the positions of an operator-actuatable load lever for the engine, and others. Signals from the control unit are utilized to operate the clutch and, to this end, the control unit includes an arrangement for effecting a creeping movement of the vehicle when the transmission is in gear, the brake or brakes is or are idle, and the load lever is actuated. Such arrangement can effect the transmission of torque in accordance with at least one first predeterminable function to thus induce a creeping movement of the vehicle. The control unit further includes a device for effecting a starting movement of the vehicle in response to actuation of the load lever while the brake is or are idle and the transmission is in gear; such device includes an assembly for selecting the transmission of torque by the clutch in accordance with at least one second predeterminable factor.
