Abstract: A method and system for computing the phase shift or the amplitude of an electromagnetic three-phase system. The method comprises the following steps of: detecting vector values corresponding to an electromagnetic quantity by three sensors, the three sensors delivering signals that are offset from each other substantially by 0°, 120° and 240°; computing changed vector values by logically adjusting one of the detected vector values to a phase of 0°; and iteratively computing the phase shift of the three-phase system using the changed vector values.

Abstract: In an evaluation device for determining a measurement value at a component, power is supplied to the component during readout of the measurement value. A controller serves to determine the power supplied to the component during the readout. The measurement value determined by the reader is corrected by a compensator while using the power determined by the controller, so as to obtain a corrected measurement value freed from any effects caused by the power supplied.

Abstract: A device for detecting electromagnetic radiation, with a diode structure acting absorbingly for the electromagnetic radiation and having a diode, and an ascertainer for ascertaining a measurement value for the absorbed electromagnetic radiation by means of at least two current/voltage measurements at the diode for different pairs of a diode current and a diode voltage.

Abstract: For digitizing analog measurement signals, an analog-to-digital converter is used, wherein the offset to be subtracted from an analog measurement value is taken to account within a locked loop by means of which an analog-to-digital converter operating according to the modulation principle is fed back.

Abstract: In a method for imaging, a plurality of image sensor elements is used, which generate different output signal values when using different exposure times. For each image sensor element, an image signal value is generated by generating a first output signal value when using a first exposure time and an associated second output signal value using a second exposure time. If the first output signal value does not exceed a threshold value associated thereto, the image signal value is calculated using a first calculating rule on the basis of the first output signal value. If the first output signal value exceeds the threshold value, the image signal value is calculated using at least a second calculating rule on the basis of at least the second output signal value.

Abstract: In a method for imaging, a plurality of image sensor elements (12) is used, which generate different output signal values when using different exposure times. For each image sensor element, an image signal value is generated by generating a first output signal value (y1(x)) when using a first exposure time (Tint,long) and an associated second output signal value (y2(x)) when using a second exposure time (Tint,short). If the first output signal value does not exceed a threshold value (yo) associated thereto, the image signal value (y(x)) is calculated using a first calculating rule on the basis of the first output signal value (y1(x)). If the first output signal value exceeds the threshold value (yo), the image signal value (y(x)) is calculated using at least a second calculating rule on the basis of at least the second output signal value (y2(x)).
