    摘要: A micromechanical acceleration sensor includes a substrate, an elastic diaphragm which extends parallel to the substrate plane and which is partially connected to the substrate, and which has a surface region which may be deflected perpendicular to the substrate plane, and a seismic mass whose center of gravity is situated outside the plane of the elastic diaphragm. The seismic mass extends at a distance over substrate regions which are situated outside the region of the elastic diaphragm and which include a system composed of multiple electrodes, each of which together with oppositely situated regions of the seismic mass forms a capacitor in a circuit. In its central region the seismic mass is attached to the elastic diaphragm in the surface region of the elastic diaphragm which may be deflected perpendicular to the substrate plane.

    摘要: A method for self-adjustment of a triaxial acceleration sensor during operation includes: calibrating the sensor; checking the self-adjustment for an interfering acceleration, with the aid of a measurement equation and estimated values for sensitivity and offset; repeating the adjustment if an interfering acceleration is recognized; and accepting the estimated values for sensitivity and offset as calibration values if an interfering acceleration is not recognized. The step of checking the self-adjustment includes: estimating sensitivity and/or offset and the variance thereof; determining an innovation as the difference between a measured value of the measurement equation and an estimated value of the measurement equation; testing the innovation for a normal distribution; and recognizing the interfering acceleration in the event of a deviation from the normal distribution.

    摘要: A method for measuring an air mass flow flowing in a main flow direction, and a hot-film air mass meter by which the method is able to be realized. The method and the hot-film air mass meter are especially suitable for use in the induction tract of an internal combustion engine. The hot-film air mass meter includes a sensor chip having a chip surface across which an air mass flow is able to flow. The chip surface in turn has a measuring surface, the measuring surface including a central hot-film air mass meter circuit having at least one central heating element and at least two temperature sensors. The method is implemented so that the at least one central heating element is periodically heated using a frequency ω. With the aid of at least two temperature sensors, at least two measuring signals are detected. The measuring signals and/or at least one differential signal of the at least two measuring signals are modulated using the frequency ω.

    摘要: An electrolysis device producing alkali metals from a liquid alkali metal heavy metal alloy, including at least two connected tubes forming an electrolysis unit. Two solid electrolyte tubes are arranged concentrically in each tube and oriented with openings towards one end of each tube such that a first annular gap for guiding a liquid alkali metal forming an anode is located between the inside of the tube and the outside of the solid electrolyte tubes. An alloy inlet and outlet for the liquid alkali metal in each of the tubes leads into the first annular gap of a tube. An inner chamber sealed off from the alloy inlet, first annular gap, and alloy outlet in each solid electrolyte tube receives liquid alkali metal that can be used as a cathode connected to the alkali metal outlet. Two respective closure devices are arranged at the two ends of each tube.
