  • Three-dimensional profilometer
    Patent number: 9163936
    Abstract: Profilometers for industrial metrology and other applications are described. A line is projected on a surface to be profiled. The line is scanned to build a three dimensional point cloud allowing the three-dimensional (3D) profile of the surface to be determined. In some embodiments, the line is projected by a laser system. In other embodiments, the line is projected by a digital micromirror device (DMD). In still further embodiments, multiple lines, or other patterns are projected.

  • Self-normalizing panel thickness measurement system
    Patent number: 9032640
    Abstract: A measurement gauge, comprising a pair of jaws biased in a closed position; a normalizing member surrounding one of the jaws when the pair of jaws is closed, the normalizing member biased in an extended position; a handle coupled to the pair of jaws and normalizing member such that movement from an extended handle position to an retracted handle position opens the pair of jaws and moves the normalizing member to an retracted position.

  • Inverter power module with distributed support for direct substrate cooling
    Patent number: 8248809
    Abstract: Systems and/or methods are provided for an inverter power module with distributed support for direct substrate cooling. An inverter module comprises a power electronic substrate. A first support frame is adapted to house the power electronic substrate and has a first region adapted to allow direct cooling of the power electronic substrate. A gasket is interposed between the power electronic substrate and the first support frame. The gasket is configured to provide a seal between the first region and the power electronic substrate. A second support frame is adapted to house the power electronic substrate and joined to the first support frame to form the seal.
