  • Patent number: 7667831
    Abstract: The present invention provides an inspection system for inspecting a surface of an optical specimen. The inspection system includes an optical testing device having a main body and an optical axis. The optical testing device includes an optical imaging system housed in the main body. The optical imaging system includes imaging components for acquiring a microscope visual image and for acquiring at least one interference fringe image of the surface of the optical specimen. The optical testing device also includes a translational mechanism housed in the main body and configured to allow linear movement of the optical imaging system and to prevent off-axis movement of the optical imaging system.

  • Patent number: 7463435
    Abstract: An optical pattern that is to be supported for examination is formed on a surface of a substrate, generally glass. Corner brackets are fixedly mounted on the substrate. Each of the corner brackets has a support portion and a housing that mounts a locating ball or sphere that protrudes out of the housing. The housing is connected to the support portion of the respective bracket through a flexure hinge that permits movement of the housing and supported ball in a plane generally parallel to the surface of the substrate having the optical pattern.

  • Patent number: 7458221
    Abstract: A variable area nozzle comprising a concentric support and a plurality of convexly contoured self sealing vanes is disclosed and claimed. The vanes are circumferentially and rotatably mounted to the concentric support forming a nozzle infinitely positionable between a first position corresponding to a minimum area nozzle and a second position corresponding to a maximum area nozzle. A closer, which is preferably a shape memory alloy (SMA), urges the nozzle toward the first position corresponding to a minimum area nozzle. Periodically spaced openers act between adjacent vanes to urge the nozzle to a second position corresponding to a maximum area nozzle.

  • Patent number: 7416062
    Abstract: A magnetorheological device comprising a housing having a divider within the housing is disclosed and claimed. A rotary impeller having two paddles is rotatably mounted within the housing. The rotary impeller sealingly engages the divider and the paddles in combination with the divider forms a first chamber and a second chamber. Magnetorheological fluid resides in the chambers and a passageway interconnects the first and second chambers. A coil surrounds a portion of the passageway such that when energized the magnetorheological fluid solidifies plugging the passageway. As the impeller rotates, it pushes the incompressible fluid against the divider in the housing and the plug in the passageway and retards and/or stops the motion of the impeller.

  • Patent number: 6538747
    Abstract: An adapter for mounting on an interferometer to provide a phase shift of the reference transmission sphere or flat used on the output of the interferometer is made of a monolithic body separated into two portions. The first portion is a fixed end support portion that mounts on the interferometer, and the second portion is a movable end support portion that mounts the sphere or flat that is used for transmission of the optic beam. The movable end support portion is mounted and the fixed end support portion are connected through flexure hinges that permit axial movement between the support portions, and a single actuator can be used between the support portions for causing axial movement. The flexure hinges are located so the adapter is very stiff against all motions except axial motions.

  • Patent number: 6010482
    Abstract: An apparatus for visually indicating fluid flow through a fluid system or apparatus such as a medical infusion device. The apparatus comprises a pair of thin, indicia bearing films disposed in an overlaying relationship. These films are shifted relative to each other by movement of mechanical actuators which are deflected solely by the pressure of the fluid within the fluid conduits of the system of the apparatus. The two films are stacked in closed proximity and are preferably constructed from a substantially transparent flexible material such as mylar. One surface of the inferior film is printed with a plurality of integrated symbols depicting various fluid flow conditions. The superior film functions as a mask over the inferior film and is printed with a pattern of diagonally extending, alternating clear and opaque stripes. The print ratio of the superior film permits viewing at any one time of only one of the symbols printed on the inferior film.
