  • Patent number: 12004867
    Abstract: Pre-calibrated position sensors, and a computer or cloud based service are used to show motion in real time of the teeth and jaws depicting six degrees of freedom. The computer receives anatomically correct 3D images of any portion of the craniomandibular system with a position sensor(s) attached. The position sensor data is then transferred with wireless attachments to the patient to generate true to life motion of the digital 3D models of the teeth and jaws. The 3D models are then employed to provide various techniques for treating bite disorders.

  • Patent number: 11984837
    Abstract: A method for determining an angular position of a rotating component is disclosed. A sensor system is positioned at a radial distance from an axis of rotation of the rotating component. A magnetic ring is arranged fixedly and concentrically on the rotating component, generating a magnetic field that changes with respect to the sensor system. The sensor system detects the magnetic field in which a signal is captured and evaluated with respect to the angular position. Errors in the measurement of the angular position can be corrected. The signal captured by the sensor system is evaluated with respect to the amplitude information of the magnetic field. A correction parameter is determined from the amplitude information, and an angle error is of the angular position is determined based on the correction parameter. The angle error is used to correct the angular position.

    Abstract: A position sensor is configured to use a Wiegand wire, position magnet(s) and a reset magnet in which changes in polarization of the Wiegand wire caused by the position magnet(s) can be reset by the reset magnet. The position magnet(s), which can move in relation to the Wiegand wire, can have relatively stronger magnetic flux densities, and the reset magnet, which can be fixed in relation to the Wiegand wire, can have a relatively weaker magnetic flux density. When the position magnet(s) are proximal the Wiegand wire, the relatively stronger position magnet(s) overcome the reset magnet to cause a change in polarization of the Wiegand wire which produces an electrical pulse which can be counted. However, when the position magnet(s) become distal to the Wiegand wire, the relatively weaker reset magnet can reset the polarization of the Wiegand wire to prepare for a next count.
