    Abstract: The power train of a motor vehicle employs an automated transmission and an automated clutch between the transmission and the combustion engine. The clutch is automatically disengaged prior to, and is automatically reengaged after, each selection of a particular gear of the transmission. A common first actuator (such as a reversible stepping motor) is employed to select the condition of the clutch and to select various gears, and a second actuator is used to effect actual shifting of the transmission into or from a selected gear. The connection between the first actuator and a clutch operating member comprises a reciprocable or rotary first cam, and the connection between the first actuator and a gear selecting member comprises a preferably rotary second cam which receives motion from the first cam.

    Abstract: A control unit for a friction clutch or another torque transmitting system and/or for a transmission system in a motor vehicle employs an actor having an electric motor arranged to drive a single-stage or multi-stage transmission which, in turn, transmits motion to one or more mobile parts of the torque transmitting and/or transmission system by way of one or more output elements of the actor. The motor receives signals from one or more sensors and/or from the electronic circuitry in the vehicle and/or from a memory. At least one coil spring and/or another energy storing element is or can be provided to guarantee that the torque transmitting system assumes a predetermined (e.g., disengaged) condition and/or that the transmission system is in a predetermined gear ratio when the actor is not in use to change the magnitude of torque being (or to be) transmitted by the torque transmitting system and/or the ratio of the transmission system.

    Abstract: Several subscriber signals are transmitted simultaneously and at the same frequency by a central transmitter to several decentralized receivers which do not cooperate with each other, by digital message transmission in a broadcast channel. A common transmission signal, which enables an error-free individual reception, should be generated with knowledge of all subscriber signals and of the current transmission conditions, by signal preprocessing methods on the transmission side. Known nonlinear precoding methods totally suppress the interference signals, so that the channel diversity cannot be used. In the claimed precoding method, the occurring interference signals are, on the contrary, taken into account. On the basis of a modulo arithmetic calculation, the transmission channel is not totally equalized, but virtually divided, so that the transmission of the subscriber signals is continued periodically; the signals are selected according to the minimal transmission power and pre-equalized, in a linear manner, and the residual interferences, still remaining between the subscriber signals, may assume special values from a preset set of values. The set of values is selected, so that the interference signals of the other subscribers are also merely reflected in the otherwise already existing periodic continuation and can be suppressed or used as required by a modulo decision, on the reception side.
