Abstract: The invention relates to a device and a method for checking human vision, comprising an image-generating module for generating any test images, an imaging module, used to image the test image provided by the image-generating module on the retina of the eye as a stimulus, the imaging module containing at least one optical component having variable focal length, such that the test image of the image-generating module is perceptible to the eye from virtually simulated and variable distances, an accommodation measuring apparatus, a viewing direction measuring apparatus, and a control and evaluation module, which records and/or further processes the information. The accommodation of the eye can be stimulated by means of the particular test image, and the viewing direction of the eye can be measured simultaneously or in alternation, and fed to a control and evaluation module. Both eyes can be checked simultaneously by generating virtual binocular images.

Abstract: The invention relates to a method for photographically observing and/or documenting the fundus of an eye, comprising: producing a lighting beam path by means of a lighting module for lighting at least one partial area of the fundus by using an at least approximately punctiform or at least areally limited lighting source, producing an image plane in the lighting beam path for the creation of photographic recordings, separating the pupil cross-sectional area into a detectable observation region and an undetectable lighting region, producing an image area that contains the image of the fundus on the image plane, dividing the image area in strips in the lighting beam path into a lighted region and unlighted regions, and imaging the third and fourth Purkinje reflection on the image area, wherein at least one Purkinje reflection, the third and/or fourth Purkinje reflection, is located in the unlighted regions of the image area.

Abstract: The present invention relates to a supporting sleeve for a leg or arm stumps, namely a liner. The liner includes a sleeve made of an elastomeric and electrically insulating material that surrounds the stump starting from the distal end thereof. The sleeve has at least in part a surrounding layer made of a suitably conductive material.

Abstract: An electrically conductive knitted fabric comprising stitched rows of an electrically non-conductive ground thread (1), and of stitched rows of an electrically conductive thread (2) placed therebetween. In addition, a number of rows of an electrically non-conductive ground thread can alternate with one or more rows of comprising electrically conductive thread. A connection overlapping the rows comprising electrically non-conducting thread exists in places between the rows comprising electrically conductive thread.

Abstract: The invention relates to a connection part for prostheses, in particular a locking member (6) comprises a bore with a spring-loaded catch for a grooved or ratcheted contour of the pin (4) and a release device for the locking member that can be actuated in opposition to the force of the spring. The locking member (6) also comprises an integrated clamping mechanism for a cord (21) of a prosthetic liner, without a pin, said cord being pulled to introduce the liner into the prosthetic shaft.

Abstract: Minimal orthesis for the treatment of osteoporosis comprising a rigid brace propping the spine as well as fastening structure for the brace guided around the truncus whereas the brace extends in a supporting manner essentially along the whole length of the spine, wherein the brace is provided with lower fastening belts for encompassing the truncus, the fastening belts being arranged at a height where they are not hindering abdominal respiration and the brace is provided with upper fastening belts which are guided in the way of rucksack straps over the shoulders and back underneath the arm pits so that they do not hinder thoracic respiration.

Abstract: A frame-construction hyperextension orthotic device with several truss pads resting on the patient's body is described in which the individual rod elements (13, 14) provided with oblong holes (14) can be adapted in a continuously adjustable manner to the individual requirements and can be stopped in the desired position by setscrews (17).
