Abstract: An integrated optical mode transformer provides a low loss interconnection between an optical fiber and an integrated optic waveguide having a spot size different from that of the fiber. The mode transformer is comprised of two waveguide layers, an upper layer and a lower layer, with the upper layer being contiguous to the lower layer. The lower layer is the integrated optic waveguide layer forming the optical circuit. The input dimensions of the composite two-waveguide structure supports a fundamental mode that accepts all of the light present on the optical fiber. The upper waveguide layer is tapered down from an input width to an output width and then terminates in such a way that at the termination substantially all of the input optical power resides in the lower waveguide layer. The two waveguide layer structure is fabricated by deposition and planarization techniques.
Abstract: A method for repairing damaged or diseased urinary tract tissue includes providing a urinary tract tissue graft composition that includes a distal ileal segment of small intestinal submucosa. The distal ileal segment of small intestinal submucosa may be utilized as an unseeded tissue graft composition, or the distal ileal segment of small intestinal submucosa may be positioned in a tissue culture frame, and smooth muscle and urothelial cells isolated from a tissue specimen of a subject and cultured are then seeded upon the distal ileal segment of small intestinal submucosa, thereby forming a urinary tract tissue graft.

Abstract: The invention is for safety goggles to protect eyes of a user of the safety goggles. The safety goggles include a lens and a frame with a bridge. A goggle chamber is formed between the lens and the face of the user. The safety goggles have a lower ventilation assembly that admits air one either side of the bridge. The safety goggles also includes an upper ventilation assembly at an upper portion of the frame. Air enters the goggle chamber through the lower ventilation assembly, heats near a nose of the user and exits the goggle chamber through the upper ventilation assembly. Each of the lower and upper ventilation assemblies cover a corresponding lower and upper air path in such a manner that allows air to pass through the corresponding air path while preventing solid projectiles and splashed liquid from having a direct line of trajectory to the eyes of the user.

Abstract: A rack step tool for use, for example, in a warehouse which houses a plurality of storage racks which support equipment, merchandise, or other items which are stored on the shelves of the storage racks and from which the equipment, merchandise, or other items are periodically removed. The rack step tool generally includes a step member which is attached to a base plate. A pair of lugs is attached to the base plate for insertion into openings in a vertical support member of the storage rack. The rack step tool can be attached to the vertical support member at various heights and can be readily disengaged therefrom. The rack step tool may further have a securing element such as a hook for insertion into another hole in the support member for further securing the rack step tool thereto.

Abstract: The present invention relates in general to nanoparticles exhibiting luminescence such as photostimulated luminescence or photoluminescence and optical switching processes based upon such properties, in more particular, the use of such photostimulated luminescence exhibiting nanoparticles and switching nanoparticle for optical storage apparatuses and sensors as well as methods of making and using same.
Abstract: An oilfield equipment identifying apparatus comprising a computer loaded with an oilfield equipment database. A unique identification code is input into the computer for each piece of oilfield equipment in the drill string to form a reference in the oilfield equipment database to each piece of oilfield equipment in the drill string. A drilling monitoring device receives input signals indicative of at least one of rotating and non-rotating usage of the drill string and output signals to the computer wherein the computer continuously and automatically monitors the cumulative rotating usage and non-rotating usage of each piece of oilfield equipment identified in the drill string.
Abstract: The present invention relates to a nucleic acid segment having a coding region segment encoding enzymatically active Streptococcus equisimilis hyaluronate synthase (seHAS), and to the use of this nucleic acid segment in the preparation of recombinant cells which produce hyaluronate synthase and its hyaluronic acid product. Hyaluronate is also known as hyaluronic acid or hyaluronan.

Abstract: A seat assembly extending about an inlet passage of a valve and engaging a valve member is disclosed. The seat assembly includes an annular seat carrier having an annular groove formed therein, and a seat positioned in and extending from the annular groove of the seat carrier. The seat has an inner side, an outer side, and a plurality of spaced apart, concentric seal rings extending from the inner side of the seat to the outer side thereof. The seal ring nearest the inner side of the seat is engageable with the valve member to provide an innermost seal when the seat assembly is acted upon by a pressure within a pressure range and the seal ring nearest the inner side of the seat is deflectable in a radially outward direction and out of sealing engagement with the valve member when the pressure exceeds the pressure range to cause the adjacent seal ring to provide the innermost seal.
Abstract: A method for separating the orthogonal polarization components of an incident optical signal into two spatially separated output ports is described. The method comprises a Mach-Zehnder interferometer where one of the two branches has a section of waveguide that exhibits form-birefringence. This integrated optic Polarization Beam Splitter (PBS) is broadband, has high extinction ratio, and has characteristics that are tunable.
Abstract: A customer interface system for use with a check processing system. The customer interface system has a check reader and a card issuing machine.

Abstract: Disclosed are DNA sequences encoding hyaluronic acid synthase that are employed to construct recombinant cells useful in the production of hyaluronata synthase and hyaluronic acid (HA). In preferred aspects, chromosomal DNA encoding the HA synthase gene, hasA, was cloned from a Streptococcus pyoganas genomic library. These vectors were used to transform host cells such as E. coli and acapsular Streptococci to produce hyaluronic acid. Resultant transformants were screened to identify colonies which have incorporated HA synthase DNA in a form that is being actively transcribed into the corresponding HA synthase enzyme. These colonies were selected and employed in the production of hyaluronic acid.

Abstract: An auto darkening eye protection device comprising a shutter assembly and a control circuit. The shutter assembly is adjustable between a light state and a dark state. The control circuit comprises a sensing circuit, a weld detect circuit, a positive voltage generator, and a negative voltage generator. The sensing circuit senses incident light and provides an output indicative of the incident light. The weld detect circuit receives the output of the sensing circuit, and enables a dark state drive signal to be delivered to the shutter assembly. The positive and negative voltage generators output the dark state drive signal to the shutter assembly to switch the shutter assembly from the light state to the dark state upon enablement by the weld detect circuit. The dark state drive signal includes a high voltage pulse followed by a stable AC waveform. The high voltage pulse is formed by a positive voltage signal and a negative voltage signal.
