Apparatus for detecting motions of a lower jaw relative to the upper jaw of a vertebrate, comprising a first holder () to be fixed to the head of a vertebrate with a fixed assignment relative to the upper jaw for accommodating transmitter or receiver units of a position determining system () for the detection of motion, a second holder (A) to be fixed to the lower jaw on the left side for accommodating corresponding left-sided receiver and transmitter units of the position determining system, a third holder (B) to be fixed to the lower jaw on the right side for accommodating corresponding right-sided receiver and transmitter units of the position determining system, and a first evaluation unit () for processing signals from the receiver units so as to generate a differentiated dynamic image of the motions of the left and right sides of the lower jaw from relative positional changes of the transmitter units () which are associated with the motions of the lower jaw and are detected by the receiver units.

Device for detecting movements of a lower jaw

The aim of the invention is the improvement of an arrangement for the imaging of surface structures of three-dimensional objects, comprising a device for the optical recording of the surface of at least a partial region of the three-dimensional object from different positions, such that the imaging of the object can be carried out with comparatively little complexity with high reproducible accuracy. According to the invention, the arrangement thus comprises a selection circuit (), for the selection of a first image section () and a subsequent image module (), in which at least one further image section () is digitally recorded. A comparator unit () serves to compare the digital patterns () contained in the first () and the at least one further image section () and permits the generation of comparison information on the degree of matching of the digital patterns (), provided to an image processing unit (), for determination of spatial parameters and for the aggregation of the image section () of the object to give an overall image.
