Ulrich M. Landwehr has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5442444
    Abstract: An apparatus for determining the dimensions of an object such as a person uses a video or diskette or still camera, and includes further two projectors for projecting a horizontal raster line pattern at a 45.degree. angle onto the person, so that projected lines as imaged appear in superimposed relation to the person also as imaged; there is an improvement which includes a horizontal overhead mirror or a pair of horizontally positioned overhead concave mirrors, the projectors being oriented so that the raster as projected is directed towards the mirror(s) at a 45.degree. angle to that mirror, so that the projection beam is reflected at a 45.degree. angle accordingly.
    Type: Grant

  • Patent number: 4987432
    Abstract: An apparatus for acquiring the dimensions of an object by means of photography, particularly the topography of a human body, includes a still or video camera positioned to take pictures of the person is improved by a projector having a different orientation and projecting a line raster in a diverging beam; and a mirror intercepts the projection beam and provides a parallel beam wherein the horizontal line rasters as projected remain equidistant with no diverging direction; the mirror is preferably made of multiple strips but could be just a concave reflection.

  • Patent number: 4928708
    Abstract: A stand for reproducibly ascertaining the posture of a free-standing human being, includes a base plate, a central bending post and a standing plate affixed to the central post; the standing plate exerts tension upon the central post particularly when a person stands on the plate; strain gauges are affixed to the central post and the stand as a whole is improved by providing a pair of foot plates placed side by side, each foot plate is supported by a pair of rotatable tubular elements or rings on the stand plate, for elevationally adjustably mounting the respective foot plate; all these elements are driven in unison by a belt such that one foot plate is raised while the other one is lowered and vice versa.

  • Patent number: 4845518
    Abstract: An apparatus for ascertaining size and topographic measurements of a person by means of photography whereby a measuring raster is to be superimposed on an image when used by a photographic or video camera; the apparatus is improved by means of a slide raster inside the camera.

  • Patent number: 4786925
    Abstract: Horizontal lines are projected onto a person from a plurality of overhead projectors, each projecting at a 45 degrees angle, all of the projectors have parallel optical axes, the person being photographed with the projected raster superimposed.

  • Patent number: 4639107
    Abstract: The dimensions of an object are acquired photographically under utilization of a measuring raster, to be imaged in addition to a projected horizontal line raster, either by placing a raster containing plate next to the imaging plane of the camera, or by projecting a measuring raster into the camera laterally, under utilization of a semi-transparent mirror.

  • Patent number: 4370039
    Abstract: A composite photographic picture is generated through double-exposure, whereby the object, as for instance a person, is photographed on one half of the picture whereas a grid pattern is photographed on the other half; for the second exposure, person and grid pattern change position. In each instance of exposure, a line pattern is projected onto the object under utilization of one movable or two fixed, overhung projectors. Equipment is enclosed, permitting easy change of scenery.
