    Abstract: A microrelay has a switching part which is pivotably suspended on a substrate and can be moved into two alternative switching states like a rocker, by electrostatic attraction through the use of suitably attached electrodes. The switching function is brought about by electrodes which are fastened to the substrate above the rocker being shorted by metallizations or contact electrodes on an upper side of the switching part.

    Abstract: The invention relates to a video projection system that is provided with a laser that emits a laser beam. The laser beam is deflected onto the projection surface by means of a deflection unit. The projection surface contains luminous substances which generate light beams when the laser beam impinges, whereby said light beams have a predetermined wavelength. The light beams generated by the luminous substances are detected using a detection unit. The intensity of the laser beam is controlled according to desired video data and the detected light beams and by means of a control unit.

    Abstract: An angular rate sensor includes a ring that is kept floating by electrostatic forces between electrodes without the ring being mechanically or electrically contacted. The ring is divided into segments of differing radial dimensions which cooperate with a multi-phase drive from segmented electrodes to exert a torque on the floating ring which causes the ring to rotate. A control of the position of the ring and a detection of the Coriolis force that occurs are achieved by the voltages applied to the electrodes.

    Abstract: The invention relates to a component comprising a piezoelectric layer which is positioned between a first lower electrode (151) and a first upper electrode (171) as well as between a second lower electrode (152) and a second upper electrode (172). The first lower electrode (151), the first upper electrode (171), the second lower electrode (152) and the second upper electrode (172) are each structured. The structures of the first upper electrode (171) and second upper electrode (172) as well as the structures of the first lower electrode (151) and second lower electrode (152) intermesh. The above component is suitable for use as a filter, transformer and impedance adapter in high-frequency applications.

    Abstract: The invention relates to a micromechanical sensor and to a corresponding production method that includes the following steps: a) preparing a doped semiconductor wafer; b) applying an epitaxial layer that is doped in such a way that a jump in the charge carrier density in the interface between the semiconductor wafer and the epitaxial layer occurs; c) optionally etching ventilation holes traversing the epitaxial layer and optionally filling the ventilation holes with a sacrificial material; d) depositing at least one sacrificial layer, at least one spacing layer, a membrane and optionally a semiconductor circuit on the top side of the epitaxial layer using a technology known per se, wherein the semiconductor circuit may be applied after the membrane is formed or while depositing the layers required to form the membrane; e) etching a hole on the back part of the sensor, wherein the etching method is selected in such a way that etching advances in the direction of the top side and ceases in the interference between the wafer and the epitaxial layer by changing charge carrier concentration. The invention also relates to the utilization of the micromechanical sensor in pressure sensors or microphones.
