Device () for manually measuring the frequency of vibrations on a tight drive belt (), comprising a Doppler radar module () which uses a transmit antenna () for emitting a transmit beam () onto a vibrating surface of the drive belt () as well as a receive antenna () for receiving the receive beam () reflected by the surface and evaluates the receive beam () according to the Doppler principle, the vibration sensor () also comprising an acceleration sensor () in addition to the Doppler radar module (), the signals of the acceleration sensor () being calculated along with the signals of the Doppler radar module, thus allowing some signals to be disregarded.

A drive device of a window positioning device positions a window of a vehicle to selectively cover a window opening. The drive device is operated by a control device. When the window is fully closed, the drive device is operated (a) in an opening direction and then (b) in a closing direction. The operation of the drive device is carried out depending on a drive parameter. In a), using a first value of the drive parameter, the drive device is brought into a first reduced load position, and in b), using a second value of the drive parameter, the drive device is brought into a second reduced load position in which the window positioning device is in a reduced load state. A control device and a window positioning device are used.

A remote control device for a motor vehicle has a transmitting unit to transmit at least one signal, for remote control of at least one component of the motor vehicle. A switch effects transmission of the signal by operating the switch. A position detection device is provided, by which an actual position of the remote control device relative to a specifiable reference position can be detected. The signal is transmitted on the basis of the detected actual position. A method operates such a remote control device.

A watchdog function is performed for those messages which are used by a controller in a CAN bus to keep the other controllers active. All emitted keep-active messages are read again by the emitting controller itself and are checked for the presence of a reason. In the absence of such a reason, a restart is carried out.

An actuating unit for use on an electromechanically actuated disc brake for automotive vehicles including a drive unit or an electric motor, an actuating element for actuating one of two friction linings displaceably arranged in a brake caliper, and a first and a second reducing gear. The first reducing gear is comprised as a ball screw, while a planetary gear is used as the second reducing gear. To increase the efficiency, the present invention discloses a coupling shaft used to transmit forces from the planet cage of the planetary gear to the threaded spindle of the ball screw. The ends of the coupling shaft form universal joints with the planet cage and the threaded spindle.
