Abstract: A sensor device includes: a sensor module mounted on a conductor board; a sensitive element which is sensitive to a variable; a self-test control unit implementing a self-test program, the self-test control unit applying a self-test variable to the sensitive element, taking the self-test program into account; a detection unit detecting a characteristic of the sensitive element which is altered as a result of the applied self-test variable and providing an actual self-test response, taking the altered characteristic into account; and a comparator unit provided on or in the sensor module, the comparator unit comparing the actual self-test response to at least one specified setpoint self-test response and providing comparative information.

Abstract: The invention relates to a method for producing at least one compound having at least one at least monosubstituted amino group. According to the invention, a starting substance having at least one amino group is reacted with an alcohol in a reaction mixture in the presence of ammonia.

Abstract: A micromechanical structure, in particular an acceleration sensor, is described, having a substrate, a seismic mass, which is movable relative to the substrate, and at least one anchoring element, which is fixedly connected to the substrate, the seismic mass being attached to the substrate by the anchoring element, and at least one spring element being situated between the seismic mass and the anchoring element, and furthermore, the anchoring element has at least one stop element for interaction with at least one counterstop element of the seismic mass.

Abstract: A micromechanical component may include fixed electrodes and a seismic mass, the seismic mass being connected via a suspension element to a carrier substrate and being movable with respect to it. The seismic mass may include counterelectrodes, which are interconnected via a first electrically conductive connection. The fixed electrodes may include measuring electrodes and decoupled electrodes, the measuring electrodes being provided to function for an electrical evaluation, and the counterelectrodes situated across from the decoupled electrodes being provided to function as a frequency band-altering mechanical element.
