Abstract: An alignment system for optical lithography uses cameras fixed to a movable stage and to a lithography unit to view unique microscopic non-uniformities that are inherent to the surface of a work piece, e.g., metal or ceramic microcrystalline grains, for position referencing. Stage cameras image two sites on the work piece through windows in the stage to establish original position templates. After the work piece has been repositioned, e.g., reversed topside-down, the same two sites are again viewed and template matching establishes the transformed coordinates of the work piece, e.g. by a lithography unit camera under which the stage moves to approximate site locations. Two corner cameras can serve as a coarse positioning mechanism. The alignment system is particular useful for backside alignment in printed circuit board lithography.

Abstract: A system (10) for coating surfaces of a workpiece (12) comprises a biasing system (242) for connection to said workpiece (12) and an anode (76) such as to negatively bias the workpiece relative to the anode and a vacuum source (42, 44) for evacuating an interior of the workpiece (12). A gas supply (224, 226, 228) is employed for introducing a gas containing a treatment material to said workpiece and a control system (244) controls the biasing system (242), the vacuum source (42, 44) and the gas supply (224, 226, 228) so as to establish a hollow cathode effect within the workpiece (12). A pair of coupling heads (16, 18) are supported on articulated arms (22, 24, 26) movable in one or more of three axes and include removable shields (78) to protect the heads (16, 18) and an anode mount (74) for receiving an anode (76). The articulated arms allow the system to accommodate a plurality of different shaped and different sized workpieces while the shields protect the coupling heads during a deposition process.

Abstract: A drive mechanism for a lever propulsion wheelchair includes at least one clutch and at least one gear set contained within a central hub housing operatively coupled to the drive surface of the main wheel being driven. In the preferred embodiment, there are additional clutches and gear sets contained within the hub housing and coaxial to the wheel. By locating the transmission components within the hub housing and providing the coaxial arrangement, various user capabilities may be enabled without a significant increase in wheelchair width, as compared to the width of conventional pushrim propulsion wheelchairs. Transmission components are cooperatively arranged to provide capabilities that may include forward, rearward and neutral “gears,” braking, anti-rollback, and quick-release removal.

Abstract: “Corrosion” performance of an optical filter is enhanced when a relatively thick zinc-based film functions as a seed layer for a subsequently formed silver-based film. At least two pairs of dielectric and metallic layers are included within the optical filter, where the zinc-based film is a second film of the dielectric layer and where the silver-based film is the metallic layer. The zinc-based film has a zinc content of at least 80 percent and has a thickness of at least 15 nm. In order to further improve the corrosion performance, gold may be incorporated into the silver-based film.

Abstract: Methods using two to (n) purification columns to separate full length 5?-DMT-on oligonucleotides with size ranging from 40 to 180-mers from short length 5?-DMT-on oligonucleotides. Two of the said methods require using some columns sequentially with the collection and reprocessing of an intermediate fraction and are used for oligonucleotides with length ranging from 70 to 180-mers. A third method is carried out with columns stacked and used in series and is best used to purify oligonucleotides with length ranging from 40 to 80-mers. In the presence of a high ionic strength buffer, the short length DMT-on oligonucleotides bind to the top stacked columns while the less hydrophobic contaminant or DMT-off failures do not bind and/or are being washed off. In a stacked configuration, the full length DMT-on oligonucleotides are retained by the bottom column while in a 15 sequential configuration, full length DMT-on oligonucleotides are collected and reprocessed.

Abstract: A light weight reflector structure for an axial UV lamp wherein a shell-like channel housing supporting spaced apart ribs that in turn support flexed reflective spars that take the shape of the ribs. A preferred shape for the ribs and spars is parabolic about the axial UV lamp so that a beam is formed and directed out of the channel housing. The spars have a gap partially blocked by a deflector spar for creating a tortuous path for air forced direct into a tunnel between the channel housing and the spars. Forced air swirls through the gap and cools both the lamp and the spars.

Abstract: An anchor assembly having a nut which is pivotably connected to a sleeve which is slideable along a rod housing. The nut is pivotable to and from a position in vertical alignment with rod housing and a position perpendicular to the rod housing in which a threaded nut opening is in vertical alignment with a opening of the rod housing. A flange is disposed above the rod housing and a stop washer is disposed above the flange, the rod insertable within both the flange and washer. The threaded rod is insertable through the rod opening of the rod housing and threadable within the threaded opening of the nut when the nut is in a position perpendicular to the rod housing. When the nut of the anchor assembly is positioned into vertical alignment with the rod housing, the assembly can fit into a narrow hole. Once the nut clears the opening, the nut moves into the position perpendicular to the rod housing so that the rod may be threaded through the nut opening.
