    摘要： Device for pivoting a motor-vehicle mirror in or at a car from the normal position (fully-reflecting condition V) to a non-dazzle position (partly-reflecting condition T) in the event of excessive glare (B) from the headlight of a following vehicle and taking into account any interference from ambient light (U), said device comprising a voltage-source, a motor (M), the shaft (10) of which acts upon the mirror through a tilting mechanism and which is fed from thyristors (T1 and T2) which are, in turn, controlled by transistors (TR1, TR2 and TR3) with the aid of photodiodes or photoresistors (B, U) for glare and interference from ambient light. A bipolar rotary switch (DS) is connected in series with the motor (M), said switch interrupting the flow of current through the motor in accordance with a specific angle of rotation of the shaft thereof, disconnecting the previously conducting thyristor (T1 or T2) from the voltage-source and switching it off. The tilting mechanism comprises: a crank-disc (11) driven by the motor with a crank-pin (12) and a connecting rod (13) which is moved back and forth by means of said crank-pin, which connecting rod is connected to the mirror and is designed with a substantially elliptical opening (14) surrounding said crank-pin, the areas (15) thereof of greater radial extension being associated with the switching area of the rotary switch (DS), while the areas (16) of lesser radial extension are associated with the normal and non-dazzle positions (V, T) of the mirror (FIG. 1).

    摘要： The rectified output voltage of the transformer of a d.c. to d.c. converter, as represented by a voltage divider output, is compared with a reference voltage in a voltage regulator (15), the output of which is compared in a comparator (29) with a sawtooth wave to produce a sequence of pulses the duration of which depends upon the output voltage of the regulator. These pulses are provided to the transformer through a driver circuit capable of operating at a very low input voltage. One flank of the square wave produced by a component of the sawtooth wave generator is differentiated by a capacitor (39) to provide transient pulses to the transformer to keep it operating in the event the input voltage to the converter exceeds the output voltage. Another comparator (59) is provided to shut down comparator operation when there is a short circuit at the output and also for a brief start-up interval during which capacitors are charged up.
