Patents by Inventor Robert Sturm

Robert Sturm 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).

  • Optical scanning unit and method for mounting the same
    Patent number: 7525113
    Abstract: An optical scanning unit of a position measuring system for measuring a relative position of a first machine element with respect to a second machine element in a measuring direction. The optical scanning unit includes a support of a scanning grating attached to the first machine element and a detector unit attached separately to the first machine element, wherein a scanning light beam extends from the scanning grating to the detector unit as a free beam.
    Type: Grant
    Filed: October 27, 2006
    Date of Patent: April 28, 2009
    Assignee: Dr. Johannes Heidenhain GmbH
    Inventors: Wolfgang Pucher, Robert Sturm

  • Optical position transducer
    Patent number: 6933492
    Abstract: An optical position transducer is arranged to determine the relative position of two objects. The position transducer includes a scale and a scanning device that is movable in relation thereto. On sides of the scanning device, signal-generating device(s) are provided for generating positionally dependent scanning signals, among which at least one is a deflector element for selectively influencing a light beam's propagation direction. Positioned on sides of the scanning device are adjustment device(s) for spatially adjusting the deflector element, the adjustment device(s) arranged to enable merely one spatial alignment of the at least one deflector element.
