A driver device for a voltage-controlled oscillator, having an unstable voltage source, a voltage regulator, a driver for generating a control voltage for the oscillator, and a feedback loop which controls the driver as a function of the output signal of the oscillator; the voltage regulator supplying the feedback loop with operating voltage while the driver is powered by the unregulated voltage of the voltage source, and the feedback loop compensates for voltage fluctuations of the voltage source with the aid of the driver.

A multibeam radar sensor is proposed in which a holder (of resilient construction) for polyrods, in connection with a spacing element, holds the polyrods fixedly at a predetermined spacing, preferably in the range between 0 mm and 0.2 mm. The stays of the holder are fashioned such that a spring force constantly presses the spacing element against the base plate. In this context, the spring force is chosen such that the maintenance of the predetermined spacing a is ensured even under disadvantageous operating conditions such as vibration, shock, and impact.

The present invention relates to a method and an apparatus for adjusting the alignment of a beam characteristic of a distance sensor, in particular of a proximity radar for a motor vehicle. An apparatus for positioning a motor vehicle, preferably a headlight aiming device, is joined to the target object for the distance sensor. Also provided is a service unit with which measured values or data of the distance sensor can be read out. On the basis of at least one predefined criterion, the measured values or data are analyzed in such a way that necessary displacement directions of the distance sensor can be displayed by way of the service unit. Preferably the capability of the distance sensor to determine angular positions of detected target objects is utilized. Otherwise adjustment is performed to predefined reception levels.

An automotive radar system having an oscillator is described, the oscillator generating a high-frequency signal only in intervals as a function of a control signal during operation of the radar system. The oscillator includes a microwave diode, in particular a Gunn diode or an Impatt diode, accommodated inside a casing-like body. At least one of the following components, an ohmic resistor, a transistor or an IC is arranged so that it is thermally connected to the casing-like body or to an element thermally connected to the latter, the component having at least one additional function in the circuit configuration of the radar system other than generating heat. This guarantees that the oscillator will oscillate reliably even at very low temperatures and in particular in chopping operation.

A diaphragm-adjusting motor varies the setting of an adjustable diaphragm and includes a drive winding and a damping winding. A negative-feedback control circuit generates a scene-light-dependent error signal and energizes the drive winding of the adjusting motor in dependence upon the error signal. During adjusting motion of the adjusting motor, a damping voltage is induced in the damping winding. The damping voltage is utilized to modify the error signal in a sense opposing energization of the adjusting motor, so as to damp the adjusting motion of the adjusting motor and thereby prevent adjustment overshoots during normal operation. When the error signal reaches a preselected value, further energization of the drive winding of the adjusting motor is prevented. During normal operation, the lowering of the error signal effected by the damping voltage as the adjusting motor performs an automatic adjustment prevents the error signal from reaching the preselected value. However, when the adjusting motor reaches an extreme of its adjustment range and comes to a standstill, the damping voltage becomes zero. The error signal is no longer lowered by the damping voltage. If the error signal is still non-zero, the error signal will exceed the preselected value. This is detected, and further energization of the adjusting motor is prevented.

A movie camera has a film advance motor which can only operate when a relay is closed that is controlled by a transistor. This transistor can be operated by the release switch of the camera and by a circuit which senses the end of a fade-out cycle so that the film-advance motor is automatically stopped at the end of the fade-out cycle. To this end a variable diaphragm, which is provided with automatic light-adjusting circuitry is operated by a driving coil adjacent which is provided a damping coil that causes a control circuit to change the level of an output signal when the diaphragm aperture is fully closed so that at this time the film-advance motor is automatically stopped.
