In an exemplary embodiment, a magnetic field generator is arranged directly on the body or at an interval therefrom, and is designed in such manner that it generates a defined irregular field. For determining the field flux, a plurality of magnetic flux pick-ups with magnetic flux-dependent sensor elements are arranged on a carrier at an interval from one another in at least two, preferably in three, planes which stand perpendicular to one another. Moreover, the arrangement is executed in such manner that a free space is formed between the magnetic flux pick-ups corresponding to the intervals therebetween. The device is suited in particular for employment in dental medicine, and, namely, for the determination of lower jaw movements in a patient.
Device for the measurement and registration of the location, the position and/or the change of location or position of a rigid body in space, said device comprising a magnetic field generator for generating a field comprising magnetic field flux and for mounting in fixed relation to the body, sensing means for determining the magnetic field flux or the magnetic field flux change during a measurement operation, said sensing means being arranged at a distance from the magnetic field generator and being mounted independently of the magnetic field generator, and an electronic installation coupled with said sensing means for the production and evaluation of electric signals in accordance with magnetic field flux or a magnetic field flux change, said magnetic field generator (3) being designed in such manner that it generates a defined irregular field;
