A method for determining the vital functions of a vehicle occupant enables precise measurements and is easy to use without negatively affecting the vehicle occupant. The method includes determining the vital functions of the vehicle occupant using a sensor device integrated in a vehicle seat of a motor vehicle, and acquiring measurement signals of the vehicle occupant from which cardiogram signals are acquired. The method further includes using an evaluation unit to ascertain the vital functions of the vehicle occupant from the cardiogram signals. The sensor device is a magnetic field sensor device, and the cardiogram signals are magnetic cardiogram signals.

A method for measuring a magnetic field includes radiating a microwave field having a first frequency into at least one measuring location in a crystal, which comprises optically excitable color center defects at the measuring location, radiating excitation light and detecting resulting fluorescence light, applying a deformation force which results in local mechanical strain, wherein an applied first deformation force is selected such that the first frequency corresponds to a resonance frequency of the color center defects under the action of the first deformation force without the magnetic field to be measured and the detected fluorescence light becomes minimal. The method further includes placing the sensor into the magnetic field to be measured to bring about a shift in the resonance frequency and varying the applied deformation force to compensate the shift in the resonance frequency until a minimum fluorescence signal is again acquired at a second deformation force.

Magnetic field sensor and method for measuring a magnetic field

A method is for measuring phase currents of a device under test, in particular of an inverter, in which a sensor arrangement, which has a component including a crystal lattice with a defect, is arranged in a region of the device under test. The method includes using the sensor arrangement to detect a magnetic field formed by a vector of magnetic fields, the magnetic fields each in turn being brought about by one of the phase currents of the device under test, and calculating a vector of the phase currents from the vector of the magnetic fields based on a coefficient matrix.

A method for determining a rotational orientation change using an NMR gyroscope includes making use of a measure of determining, in a vapor cell, which is filled at least with a gaseous first element and a gaseous second element having non-vanishing nuclear spin, a nuclear spin component of the second element in the second direction and a nuclear spin component of the second element in a third direction. The second direction and the third direction are perpendicular to a first direction, which corresponds to the direction of the static magnetic field and to the polarization direction of the nuclear spin of the second element. Moreover, the second direction corresponds to the direction of an applied alternating magnetic field, the frequency of which corresponds to the Larmor frequency of the Larmor precession of the nuclear spin of the second element about the static magnetic field.

A method for ascertaining a change in a spatial orientation of a nuclear magnetic resonance (NMR) gyroscope having a diamond doped with color centers includes applying a static external magnetic field in a first direction, polarizing a nuclear spin of the color centers of the diamond in a direction of the static magnetic field, and generating a cophasal Larmor precession of the nuclear spin of the color centers of the diamond through application of an alternating magnetic field in a second direction perpendicular to the first direction, whose frequency corresponds to the Larmor frequency of the nuclear spin of the color centers. The method further includes measuring a phase of the Larmor precession, and ascertaining a change in the spatial orientation in a plane perpendicular to the first direction based on a deviation of the precession frequency from an expected value.
