Patents by Inventor Josef Mitterleitner

Josef Mitterleitner 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: 11940304
    Abstract: A position-measuring device includes a scale having first and second measuring graduations, which each include graduation structures that respectively extend parallel to first and second directions. A first scanning unit is associated with the first measuring graduation, and second and third scanning units are associated with the second measuring graduation. A fourth scanning unit is associated with the first or second measuring graduation. In the former case, a first straight connecting line running through scanning locations of the first and fourth scanning units and a second straight connecting line running through scanning locations of the second and third scanning units are parallel or form a predetermined angle therebetween that is not equal to a sum of the angles of the first and second directions. In the latter case, the scanning locations of the second, third and fourth scanning units do not lie on a common straight connecting line.

  • Patent number: 11125548
    Abstract: A position-measuring device includes a carrier body and scanning units movable relative thereto. At least three surfaces of the carrier body each carry a first and second measuring graduation, each having a series of graduation lines. Each of the measuring graduations is associated with a scanning unit for scanning the respective measuring graduation at a scanning location such that, for each surface, two scanning units are disposed for scanning the respective measuring graduations. In each case, these two scanning units are disposed in such a way, and the graduation lines of the two measuring graduations are inclined with respect to each other in such a way, that two normal planes extending respectively in the direction of the respective graduation lines through the respective scanning locations of the two scanning units have a common axis of intersection, whereby the three resulting axes of intersection extend through a common point.
