Patents by Inventor Martin Sundin

Martin Sundin 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).

  • Position measuring device for detecting displacements with at least three degrees of freedom
    Patent number: 6593729
    Abstract: The invention comprises a fixed platform (1) and a displaceable platform (2) that are coupled by six tension springs (3) and an elastic spacer member (6). The spacer member forms with each platform, for instance, a ball-and-socket joint, such that the platforms can be displaced in a total of five to six degrees of freedom in respect to each other. The displacement is detected by measurements at the tension springs (3) or at the spacing member (6). This is preferably done by measuring the inductivity of the tension springs (3), thereby making it possible to easily determine the relative position of the platforms.

  • Position measuring device for detecting displacements with at least three degrees of freedom
    Patent number: 6329812
    Abstract: The invention comprises a fixed platform (1) and a displaceable platform (2) that are coupled by six tension springs (3) and an elastic spacing element (6), which forms with each platform, for instance, a ball-and-socket joint, so that the platforms can be displaced in a total of five to six degrees of freedom with respect to each other. Displacement is detected by measuring at the tension springs (3) or at the spacing element (6). This is preferably done by measuring the inductivity of the tension springs (3), thereby making it possible to easily determine the relative position of the platforms.
