  • Integrated micro actuator and LVDT for high precision position measurements
    Patent number: 10337890
    Abstract: A single housing with a non-ferromagnetic piezo-driven flexure has primary and secondary coil forms of different diameters, one coaxially inside the other, integrated in the flexure. The cylinders defining the planes of the primary and secondaries do not spatially overlap. The secondary coil forms may be wound in opposite directions and wired to provide a transformer device. Movement of the primary relative to the secondaries in the direction of the central axis of the coils can be differentially detected with high precision.
    Type: Grant
    Filed: December 13, 2016
    Date of Patent: July 2, 2019
    Assignee: Oxford Instruments AFM Inc
    Inventors: Roger Carlos Proksch, Dan Bocek, Jason Cleveland, Matthew Longmire, Matthew Klonowski
