  • Patent number: 9068824
    Abstract: An endoscope having two entry lenses, which are arranged spaced from each other and the fields of view of which overlap, and having guiding devices. The entry lenses are spaced so far apart from each other that the outer edges thereof protrude beyond the cross-sectional area of the guiding devices, and a lens displacing the axis beam is inserted between one entry lens and the guiding devices. A method for the use of the endoscope.

  • Publication number: 20130116574
    Abstract: The invention relates to a method for ascertaining spatial coordinates in which at least two markers are put on a living being and at least two cameras in a stereo arrangement are used to ascertain the spatial coordinates of the markers, wherein the spatial coordinates of the markers are compared with a reference and the difference is calculated and output. The invention also relates to quantitative length and angle measurements using optical, stereometric measurement systems for medical applications.

  • Patent number: 8343014
    Abstract: A reversible toe manipulation device comprising a separator for inserting between two toes of the human foot, the separator including a duality of shaped openings, each shaped opening adapted for receiving at least one toe and the shaped openings being from 0.25 to 2.0? in depth, at least one of the shaped openings fully attaching around one or more toes so that the separator is attached to the feet and toes, the separator further comprising an adjustable stretch width section that can be altered using a removable stretch width section to the width desired by the wearer, said adjustable stretch width section interposed between the shaped openings, the separator spreading the toes between 0.25 to 2.0? in width, such that when the toes are inserted into the shaped openings the toes are contactless.

  • Patent number: 8328731
    Abstract: The method for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha comprises—for each of a multitude of points (12) on said surface (14)—the step of using a chromatic coded distance measurement technique for determining a distance value (40) representative of a distance to said point (12); and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (40).

  • Patent number: 8320612
    Abstract: In order to develop known tracking systems, in particular in the medical field, the invention proposes a device for the contactless determination and measurement of a spatial position and/or spatial orientation of bodies using a tracking system, by means of which the bodies are located and brought into relation with one another, the tracking system, or at least components or modules thereof, being mobile.

  • Patent number: 8264696
    Abstract: Disclosed is a measuring instrument for determining geometric properties of a profiled element. Said measuring instrument comprises:—a device that generates at least one first light beam (7) and a second light beam (8), the direction of radiation of the first light beam being different from the direction of radiation of the second light beam;—a retro-reflecting surface (3) which is arranged in such a way relative to the light source that at least some of both light beams is incident on the retro-reflecting surface; and—a recording device (14) which can determine, across the transversal extension thereof, the light intensity distribution of at least some of the reflected light beam of the first light beam and at least some of the reflected light beam of the second light beam, the first light beam being reflected by the retro-reflecting surface and the second light beam being reflected by the/a retro-reflecting surface.
