Abstract: It is described an arrangement (230, 330, 430, 530) and a method for tracking a movement of an upper jaw (100) relative to a lower jaw (120), the arrangement comprising: a lower mounting structure (231) mountable relative to the lower jaw (120); at least one lower motion sensor system (233) mounted at the lower mounting structure; and at least one data transmission unit (127) adapted to transmit measurement data (245) from the lower motion sensor system to an analysis unit (239).

Abstract: The present invention relates to optical instruments, in particular to magnification loupes, stereo-magnification loupes and magnification viewers, such as those worn by dentists and surgeons. The objective lens of the optical instrument is protected from mechanical and/or chemical damage.

Abstract: The present invention provides an optical stereo device with an autofocus feature as well as a corresponding autofocus method for optical stereo devices. The optical stereo device has imaging means configured to provide a stereo image of an object of interest by means of combining a right eye image and a left eye image and a control unit operatively connected to the imaging means and configured to receive the right eye image and the left eye image and to adjust the focus position of the imaging means.

Abstract: A support system (10) and method for the viewer-dependent positioning and alignment of a monitor (20) is disclosed. The support system (10) comprises a central support column (14), a first arm (16) having an adjustable length L, wherein the first arm (16) is rotatably connected at its proximal end to the central support column (14) and is pivotally connected at its distal end to the monitor (20), a second arm (18), wherein the second arm (18) is connected at its distal end to a camera (50), and control means for positioning and aligning the monitor (20) such that irrespective of the angular position of the viewer (i) the monitor (20) is positioned along the line of sight of the viewer pointing towards a reference position, (ii) the distance from the monitor (20) to the viewer (40) is held constant, and (iii) the monitor (20) is at a right angle with respect to the line of sight of the viewer (40) pointing towards a reference position.

Abstract: An X-ray image sensor, comprising an X-ray converter layer for converting X-rays into signals received by a semiconductor detector for sampling and detecting converted X-rays as electrical signals, and a connection substrate comprising electrical connections, the X-ray converter layer bonded to a first surface of the semiconductor detector and the connection substrate arranged at a second surface of the semiconductor detector, opposite the X-ray converter layer, wherein the semiconductor detector in at least one edge portion comprises vias for through-contacting detector elements formed in or on the first surface of the semiconductor detector to the connections substrate.

Abstract: A digital X-ray image sensor device comprising a fibre-optic scintillating layer for converting X-rays into optical radiation and a photoelectric conversion layer for converting the optical radiation into electrical signals, the photoelectric conversion layer comprising an array of CMOS sensor elements, wherein each of the sensor elements has a composite exposure response characteristic comprising a low exposure region characterized by a first gain and a high exposure region characterized by a second gain, wherein the first gain is higher than the second gain.

Abstract: An eyewear is described comprising two segmented look-through elements each comprising an upper and a lower segment, wherein the upper segments are provided with means to selectively direct an image to the left and/or to the right eye. Preferably, said means are configured as LCD shutter glasses, optically polarized glasses, red and green glasses or as display units. The two lower segments of the two look-through elements are preferably configured as normal glasses including a pair of magnifying glasses. The eyewear can be used in a variety of environments including, in particular, the medical field and industrial processes. Furthermore, a system is described comprising such an eyewear as well as a display device to be looked at by means of said eyewear.
