  • Publication number: 20190282421
    Abstract: An operating table with a patient support surface, or a ceiling unit having one or more arms, includes at least one component which can be moved by an actuator. The devices include a user interface via which a user can input a command for moving the component to a user interface microcontroller. A control device can query data of the user interface microcontroller, authenticate it and, upon a successful authentication, to control the actuator in order to move the component in accordance with the command of the user. The control device can include a first microcontroller and a second microcontroller.

  • Patent number: 8449434
    Abstract: The invention relates to a method for controlling an automated friction clutch arranged in a drive train of a motor vehicle between an internal combustion engine and a transmission, and is operated in a travel-controlled manner by means of an actuator controlled by a control unit and transmits a maximum clutch torque while the friction clutch is closed, where an engine's torque provided by the internal combustion engine is reduced when the maximum clutch torque is exceeded and is increased when the maximum clutch torque rises. The engine torque is reduced which corresponds to a reduced transmittable clutch torque when the reduced transmittable clutch torque is detected and is increased to the engine torque corresponding to the maximum transmittable clutch torque after a first time interval expires, where the engine torque is limited by means of a second, longer time interval when a reduced transmittable clutch torque is detected.
