The determination of the sensitivity includes steps for determining the sensitivity of the magnetic field sensor along a first measuring axis and for determining the sensitivity of the magnetic field sensor along the other measuring axes based on the sensitivity of the first measuring axis and the determined offset.

Calibration of a triaxial magnetic field sensor

In a method for determining an offset of measured values of a multiaxial directional sensor using a superposed signal, a large number of multiaxial measured values are recorded first. Measured values, which are recorded in different orientations of the directional sensor, form a geometric figure in a coordinate system resulting from the measuring axes of the sensor, the ideal form of the geometric figure being known and the ideal center point of which being located at the origin of the measuring axes. In the case of a biaxial sensor, the geometric figure is a circle; in the case of a triaxial sensor, it is a sphere around the origin. The superposition caused by the interference is reflected in that the center point of the geometric figure is shifted in relation to the origin of the measuring axes. The offset is measured by determining this shift.

Method for compensating a measured value offset

In a method for determining an idle state: acceleration values are ascertained as a function of three spatial directions; a comparison value is generated from the acceleration values for each of the three spatial directions; each of the comparison values is compared with a threshold value; an interrupt signal is generated if the comparison value is less than the threshold value for each of the three spatial directions; and an electronic component is switched from a power saving state to an operating state as a function of the interrupt signal.

Method and system for determining an idle state

A rotation rate sensor comprises a substrate and two structures which move relative to the substrate on a design plane (x-y), with the two moving structures being coupled to form a coupled structure such that the coupled structure has a first oscillation mode with antiphase deflections of the moving structures in a first direction (x) on the design plane (x-y) as excitation mode. The coupled structure has a second oscillation mode as a detection mode which is excited by Coriolis accelerations when the first oscillation mode is excited and on rotation about a sensitive axis (z) of the rotation rate sensor. The sensitive axis is at right angles to the design plane (x-y), and the coupled structure is designed such that, subject to optimal preconditions, it does not have any oscillation mode which can be excited by linear accelerations of the rotation rate sensor in a direction parallel to the second axis.
