Abstract: An electronically processed single-step test device for detecting the presence of a preselected analyte in a fluid. The device includes a hollow rectangular outer casing, disposed within co-joined upper and lower sections of the casing are assay material, an electronic processing system, and a display. The display is observable through a viewing window. The assay material is a sorptive material including a fluid sample application region in the form of a sample wick in fluid communication with a test strip. The test strip includes an analyte capture region adjacent to a light shield. The system includes lights which are alternately pulsed or energized over predetermined periods of time to determine if fluid test results show a marker or markers in the capture region indicative of the presence of a preselected analyte in the fluid. If so, Yes+ is displayed on the display otherwise, No? is displayed on the display.

Abstract: Improved connectors for optically coupling a fiber optic transmission line and an opto-electronic device electrically interfaced to a substrate. The improved connectors include the opto-electronic device being mounted on the substrate, such as a printed circuit board, and means for mounting the fiber optic transmission line to the substrate such that the operative axis of the opto-electronic device is substantially not coincidental with the light transmission axis of the fiber optic transmission line. The connectors also require light bending means in operative optical association with said opto-electronic device for directing along the light transmission axis of the fiber optic transmission line at least a portion of the light emitted from said opto-electronic device or for directing along the operative axis of said opto-electronic device at least a portion of the light emitted from said fiber optic transmission line.

Abstract: The present invention is directed to a device and method for precise positioning, or alignment of two or more articles with respect to each other. The device comprises a Unistructural Mass of Inherent Memory Polymer with two or more internal cavities which have inherent shapes with at least one cross-sectional configuration which is congruent to a cross-sectional configuration shape of the said article(s) in the positioned or aligned position(s). The unistructural mass cavities have cross-sectional configurations which are the same or smaller than those corresponding to the positions of the articles. The unistructural mass also includes at least one separate access cavity. It is deformed such that the articles can be readily inserted into the corresponding cavities.

Abstract: The present invention is directed to a device and method for precise positioning, or alignment of one or more articles with respect to the device or to each other. The device comprises one or more elements of Unistructural Mass of Inherent Memory Polymer with one or more internal cavities which have inherent shapes with at least one cross-sectional configuration which is congruent to a cross-sectional configuration shape of the said article(s) in the positioned or aligned position(s). The unistructural mass has cross-sectional configurations which are the same or smaller than those corresponding to the positions of the articles. The unistructural mass is deformed such that the articles can be readily inserted into the corresponding cavities. In one embodiment, a single unistructural mass has a single cavity for precision positioning of the article. In another embodiment, the mass has at least two cavities for article alignment.

Abstract: The present invention involves a multiple cavity optical fiber splice made of a unistructural mass of inherent shape memory polymer material. The unistructural mass has a longitudinal dimension with opposite ends which includes at least a first bore at one end and at least a second bore and a third bore at the other end wherein the bores go into the mass and at least two connect to each other. The unistructural mass has two shapes, the first shape is a unique, recoverable, predetermined inherent shape wherein each bore has a preset diameter to accommodate and tightly hold end segments of denuded optical fibers of predetermined diameter and the second shape is a deformed shape which may be caused by solvent swelling and partial shrinking of the inherent memory polymer material such that each bore has enlarged predetermined diameters greater than the diameters of the segments of the denuded optical fibers so as to freely receive the end segments of the denuded optical fibers.

Abstract: The present invention involves an optical fiber splicer made of a unistructural mass of inherent shaped memory polymer material. The splicer has a longitudinal dimension with opposite ends having first bore at one end and a second bore at the other end wherein the bores go into the mass and to each other. Preferably, the first bore and the second bore are merely a single continuous oriface. The unistructural mass has a first shape and a second shape. The first shape is a recoverable, predetermined inherent shape wherein the first bore and second bore each have a preset diameter to accomodate and tightly hold end segments of denuded optical fibers of predetermined diameter in spliced, butted alignment with one another. The second shape is such that the first bore and second bore each have swollen predetermined diameters which are greater than the diameters of the end segments of optical fibers so as to loosely and freely receive the end segments.
