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.

Method and device for inspecting a surface of an optical component

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.

Optical fiber inspection device

An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a novel adjustable flow rate control means for precisely adjustably controlling the rate of fluid flow from the reservoir of the device.

Variable rate infusion apparatus with indicator and adjustable rate control

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.

An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a fill assembly comprising a prefilled vial that can be used to fill the fluid reservoir of the device with a selected medicinal fluid.

Fluid delivery apparatus with flow indicator and vial fill

An elastomeric bladder stored energy type infusion apparatus that can be filled with a medicinal fluid and, after being filled, can efficiently delivery the medicinal fluid to the patient at a selected rate. The apparatus includes a delivery component for delivering medicinal fluid to the patient and a fill component that can expeditiously be used to fill the fluid reservoir of the delivery component in the field.

Fluid delivery apparatus with reservoir fill assembly

An apparatus for delivering fluids at a precisely controlled rate which includes a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is factory filled with the medicinal fluid to be delivered to the patient. The dispenser component embodies a highly novel fluid flow indicator that provides a readily discernible visual indication of fluid flow status through the device.

An apparatus for delivering fluids at a precisely controlled rate which comprises a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The dispensing component can be used for the precise infusion of pharmaceutical fluids to an ambulatory patient at controlled rates. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is partially received within a novel adapter subassembly that can readily be removably interconnected with the fluid dispensing component.

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.
