Abstract: The present invention relates to an inertial sensor, preferably an acceleration sensor or multi-axis acceleration sensor as a microelectromechanical construction element, said sensor comprising a housing with at least one first gas-filled cavity in which a first detection unit is disposed moveably relative to the housing for detection of an acceleration to be detected, wherein the inertial sensor comprises a damping structure.

Abstract: Exemplary embodiments relate to a sensor for detecting an acceleration acting on the sensor, having: a substrate, a mass unit, which acts as an inert mass in the event of the presence of an acceleration, a fixing structure, wherein the mass unit is articulated on the substrate in such a way that at least one pivot axis is defined, about which the mass unit can perform a rotation relative to the substrate as a result of an acceleration acting on the sensor, and the mass unit has an interial center of gravity, which is at a distance from the respective pivot axis, and at least one detection unit, with which a change in position between the mass unit and the substrate may be detected. The detection unit is arranged with respect to the mass unit in such a way that a deformation of the mass unit cannot be transferred to the detection unit.

Abstract: An electronic circuit arrangement for receiving low-frequency electromagnetic waves is proposed, having an inductor (L) acting as an antenna for generating a received signal, having a first receiver (2), connected to the inductor (L), for decoding a first component of the received signal and having a second receiver (3), connected to the inductor (L), for decoding a second component of the received signal, wherein at least the second receiver (3) is connected to the inductor (L) via an attenuator element (4) having adjustable attenuation, wherein at least one adjustment signal generation circuit (5, 6) is provided for generating an adjustment signal corresponding to a voltage of the received signal which is fed to the attenuator element (4) for adjusting the attenuation.

Abstract: The invention relates to a micro-gyroscope for detecting motions relative to an X and/or Y and Z axis, particularly as a 3D, 5D, or 6D sensor. Sample masses are disposed uniformly about an anchor and can be driven radially relative to the central anchor. Anchor springs are disposed to attach the sample masses to a substrate, and these sample masses can be deflected both radially within and out of the X-Y plane. A sensor mass is disposed on one of the sample masses by means of sensor springs, and the sensor springs allow deflection of the sensor mass within the plane of the sample mass, and orthogonal to the radial drive direction of the sample masses. Drive elements oscillate these sample masses in the X-Y plane, and sensor elements captures the defection of the sample masses due to the Coriolis forces generated when the substrate is rotated.
