  • Method to characterize nanofiber assemblies from images
    Intellectual Property Available to License

    US Patent 9,639,926 B1
    • Image processing tool for automatic feature recognition and quantification

    A system for defining structures within an image is described. The system includes reading of an input file, preprocessing the input file while preserving metadata such as scale information and then detecting features of the input file. In one version the detection first uses an edge detector followed by identification of features using a Hough transform. The output of the process is identified elements within the image.

    Intellectual Property Available to License
    US Patent 8,130,902B2
    • High-Resolution, Active-Optic X-Ray Fluorescence Analyzer (IN-06-085)

    Active optics apparatus and method for aligning active optics are provided for a high-resolution, active optic fluorescence analyzer combining a large acceptance solid angle with wide energy tunability. A plurality of rows of correctors selectively controlled to bend an elongated strip of single crystal material like Si (400) into substantially any precisely defined shape. A pair of pushers engages opposite ends of the silicon crystal strip exert only a force along the long axis of the crystal strip, and does not induce additional bending moments which would result in a torsion of the crystal.

  • A method to fabricate dielectric capacitors with increased capacitance and durability that can boost the capability of power electronics.
    Intellectual Property Available to License

    US Patent 9,646,766 B2
    • Method of making dielectric capacitors with increased dielectric breakdown strength (IN-10-096)

    The invention is directed to a process for making a dielectric ceramic film capacitor and the ceramic dielectric laminated capacitor formed therefrom, the dielectric ceramic film capacitors having increased dielectric breakdown strength. The invention increases breakdown strength by embedding a conductive oxide layer between electrode layers within the dielectric layer of the capacitors. The conductive oxide layer redistributes and dissipates charge, thus mitigating charge concentration and micro fractures formed within the dielectric by electric fields.

    Multifaceted effort in the Physics Division to prepare for EIC, collaboration between Medium Energy, Theory and Accelerator groups, together with HEP and MSD.
  • Set of highly precise, specially designed conical springs to control positioning of magnets in undulators for synchrotron radiation and free electron laser applications
    Intellectual Property Available to License

    US Patent 9,355,767 B2
    • Undulator with dynamic compensation of magnetic forces (IN-14-042)

    A method and apparatus for implementing dynamic compensation of magnetic forces for undulators are provided. An undulator includes a respective set of magnet arrays, each attached to a strongback, and placed on horizontal slides and positioned parallel relative to each other with a predetermined gap. Magnetic forces are compensated by a set of compensation springs placed along the strongback. The compensation springs are conical springs having exponential-force characteristics that substantially match undulator magnetic forces independently of the predetermined gap. The conical springs are positioned along the length of the magnets.

  • Method to make tailored devices with interesting electrical optical properties for sensors, photonic devices or other electro-optical aplications

    • Polymer-hybrid electro-optic devices and method of fabricating polymer-hybrid electro-optic devices (IN-15-133)

    A polymer-hybrid electro-optic device is fabricated by providing a semiconductor substrate, depositing a metal electrode layer on the semiconductor substrate, depositing a dielectric barrier core layer within a gap of the metal electrode layer, patterning a polymer layer to cover the dielectric barrier core layer and partially covering the metal electrode layer, infiltrating the polymer layer with an inorganic component to form a hybrid oxide-polymer layer, and removing excess inorganic component from the semiconductor substrate and metal electrode layer.

    US Patent 10,079,305
    • Method for phase retrieval to reduce a sampling requirement when imaging a dynamic process (IN-15-146)

    A method for retrieving phase information in a coherent diffraction imaging process includes acquiring a plurality of 3D data sets, each 3D data set corresponding to one of a plurality of time states, and reconstructing a 3D image of the object at a given time state using the 3D data set from all of the time states. Each 3D data set is acquired by: illuminating an object positioned in a first position with a coherent beam; measuring a first 2D diffraction pattern using an area detector; rotating the object around a tilt axis thereof to a second position that is different from the first position; re-illuminating the object positioned in the second position with the coherent beam; re-measuring a second 2D diffraction pattern using the area detector; and repeating the rotating, re-illuminating and re-measuring steps such that each 3D data set includes a predetermined number of diffraction patterns.

    • Optical design for laser encoder resolution extension with three-dimensional motion decoupling (IN-01-136)

    The optical system includes a first prism mounted on a moving target, and a plurality of prisms, a retroreflector, a laser source, and a detector mounted on a fixed base.

    An optical system is provided for laser encoder resolution extension with three-dimensional motion decoupling capability. The optical system includes a first prism mounted on a moving target, and a plurality of prisms, a retroreflector, a laser source, and a detector mounted on a fixed base. The moving target has three-dimensional linear motion freedom. The first prism on the moving target and the plurality of prisms and the retroreflector on the fixed base reflect a laser beam from the laser source to the detector define a three-dimensional optical path. The three-dimensional optical path provides multiple times optical resolution extension power for linear displacement measurement and encoding. This optic system is only sensible to the target motion on X direction and is substantially unaffected by movement in the Y and Z directions.
