Embodiments of the present invention provide a level converter circuit with a resistor and a current adjustment circuit. The resistor is connected between an input and an output of the level converter circuit. The current adjustment circuit is configured to influence a current through the resistor such that an output voltage of the level converter circuit does not exceed a maximum allowable value.

The present invention relates to a color sensor having at least one photosensitive element, in front of which a layer stack of dielectric layers and structured metal layers is constructed, and at least one color filter, through which optical radiation incident on a light input side of the color sensor is filtered before it reaches a photosensitive surface of the photosensitive element. In the suggested color sensor, an array of angle-selective passageways is provided for the optical radiation between the light input side and the photosensitive surface, and each passageway only allows parts of the optical radiation incident on the light input side of the color sensor within a limited angle of incidence range relative to an axis extending perpendicularly to the colour filter to pass through to the photosensitive surface. When the color sensor is manufactured with semiconductor technology, it enables the angle-selective structures to be integrated in the CMOS layer stack. In this way, ultra-flat color sensors can be made.

The present invention relates to an optical bandpass filter system that has at least one combination of a bandpass filter that provides a first nanostructured metallic layer () and a bandstop filter comprising a second nanostructured metallic layer (), which are arranged one behind the other, and the layer thicknesses of which are different. The bandstop filter is tuned to the bandpass filter in such a way that it blocks a contiguous wavelength range that partially overlaps a pass-band width of the bandpass filter. With the suggested optical filter system it is possible to create various filter characteristics side by side in a small space with a small pass-band width.

A Hall sensor array for offset-compensated magnetic field measurement comprises a first and at least one additional pair of Hall sensor elements. Each Hall sensor element has four terminals, of which two act as power supply terminals for supplying an operating current and two act as measurement terminals for measuring a Hall voltage. Respective first supply terminals of each Hall sensor element are connected together and to a first terminal of a common voltage source and respective second supply terminals of each Hall sensor element are connected together and to a second terminal of the common voltage source so that the common voltage source supplies an operating current for the Hall sensor elements. The Hall sensor elements are operated in the spinning current mode so that the offset voltages of the Hall sensor elements approximately cancel one another out in a revolution so that the Hall signal contributions which actually depend on the magnetic field remain.

A device for non-contractual measurement of the speed of an object moving over a surface comprises a means for radiating a signal of fixed frequency at an angle onto the surface in or against the direction of motion, said angle being variable by the movement of the object, and for receiving a Doppler-shifted signal reflected at the surface. A means is provided for combining a plurality of reflected Doppler-shifted signals, which are received in temporal succession, so as to produce a combined spectrum. The device for non-contractual speed measurement additionally comprises a means for detecting from the combined spectrum the spectral portion having the highest or lowest frequency and exceeding a predetermined signal power, and a means for deducing the speed from the frequency of the detected spectral portion.
