Abstract: The invention pertains to an angle of rotation sensor, wherein a magnet that is arranged such that it can be turned relative to a sensor that is sensitive to magnetic fields is coupled with a rotatable body, the angle of rotation (&agr;) of which needs to be measured. The invention aims to significantly broaden the measuring range of such an angle of rotation sensor. The invention proposes to utilize an asymmetric magnetic field such that the maximum and the minimum of the magnetic field measured by the probe are spaced apart by an angular range in excess of 270°. Advantageous additional developments pertain to other options for adapting the magnetic field to the desired shape. These options include an air gap that changes over the angle of rotation and the utilization of asymmetric pole shoes.

Abstract: Ozone-splitting catalytic converters can be monitored through the use of conductivity sensors for detecting ozone. Since such sensors rapidly attain operational readiness have low source sensitivities to other gases, and an adequate service life, they can be used in practical applications. Different methods of operation are capable of optimizing the ratio between ozone sensitivity and transverse axis sensitivity of the sensors.

Abstract: A device for monitoring the state of a window pane includes an optical emitter which emits a light beam on to the window pane. The device also contains an optical receiver which detects light of the light beam modulated by the window pane and, as a result, generates a received signal. The emitter and the receiver are arranged at a distance from the window pane. An evaluation circuit evaluates the received signal in order to determine the state of the window pane.

Abstract: A process for determining the distance (D) between a distance sensor and an object. A transmitter sends wave pulses with a predetermined first frequency fb 1 and the wave pulses reflected by the object are received by a receiver and are directed in the form of an analog electrical incoming signal to an A-D converter. The latter scans the incoming signal with a second frequency f2 with f2>f1 and converts it into a digital signal Z(t) which is evaluated for determining a distance value (D) in the following manner: a) Evaluation of the digital signal Z(t) for determining a first wave pulse propagation time (T1); b) k-fold repetition of the step a) for determining the total k wave pulse propagation times (T1, T2, . . . , Tk); c) Calculation of a mean wave pulse propagation time (T=(T1+T2+ . . . +Tk)/k); and d) Calculation of the distance value (D) in accordance with D−v=T/2.

Abstract: A process for determining the distance between a distance sensor and an object, wherein an analog input signal is directed to a transmitter of the distance sensor. The transmitter emits a wave which is reflected by the object. A receiver of the distance sensor receives the reflected wave and thereupon emits an analog output signal whose level is dependent upon the distance and/or the type of object. The output signal is amplified by a subsequently added amplifier. The amplifier signal is directed to an analog/digital converter and is converted into a digital signal. The digital signal is directed to an evaluation circuit for the computation of a distance value. The signal amplification of the amplifier is controlled in an adaptively dependent manner on the level of the output signal and/or in a manner dependent on the signal value of an amplification signal made available by the evaluation circuit which is characteristic of an anticipated distance range.
