  • Methods and systems for ultra-precise measurement and control of object motion in six degrees of freedom by projection and measurement of interference fringes
    Patent number: 7705996
    Abstract: A system and method for active visual measurement and servo control using laterally sampled white light interferometry (L-SWLI) for real-time visual tracking of six-degree-of-freedom (6 DOF) rigid body motion with near-nanometer precision. The visual tracking system is integrated with a 6 DOF motion stage to realize an ultra precision six-axis visual servo control system. Use of L-SWLI obtains the complete pose of the target object from a single image frame to enable real-time tracking. Six-degree-of-freedom motions are obtained by measuring the fringe pattern on multiple surfaces of the object or from a single surface with additional information gained from conventional image processing techniques.

  • Adjustable bed frame assembly
    Patent number: 7690058
    Abstract: An adjustable bed frame assembly includes a clamp which fits with two aligned and overlapping frame rails, including horizontal and vertical legs of the frame rails, to enable relative adjustment of the frame rails and to fix the bed frame at a set dimension. A leg mount extends from the clamp with a structure for mounting a vertical leg for additional elevation and support of the bed frame. The vertical extent of the leg is also adjustable by interconnection with one or more extension pieces. The configuration of the clamp and the leg mount both stiffens the bed frame and provides a very rigid support member for the bed frame. The leg mount can be formed from a single piece of metal with an open seam, and the extension pieces can be formed from a single piece of metal with an open seam.
