Abstract: Charged-particle-beam (CPB) projection-exposure methods, apparatus, and reticles are disclosed that can be used for efficiently and accurately measuring and correcting various reticle distortions. A reticle is segmented into multiple exposure units grouped into stripes. In a stripe, peripheral exposure units define second alignment marks for measuring reticle distortion arising from loading the reticle in the CPB projection-exposure apparatus. The reticle includes struts arranged into a grillage separating individual exposure units from one another. The struts define first alignment marks for measuring reticle distortion arising from reticle fabrication. The positions of the first alignment marks are measured in advance to obtain distortion data for each respective exposure unit. After loading the reticle in the CPB projection-exposure apparatus, the positions of the second alignment marks 51 are measured to obtain data on reticle distortion arising from loading the reticle.

Abstract: A standard user interface enables a user to filter an arbitrary unfamiliar data set intuitively and effectively. The illustrated interface includes a header control presenting labels, filters, and pulldown menus for each attribute of a data set, presented by an associated display control. The control communicates with a data provider through a set of APIs included in the computer's operating system. Through these APIs the data provider indicates the labels and menus to be displayed, while the header control passes new filter criteria to the data provider as it is specified by the user. The data provider filters the data set according to the user-specified filter criteria, and returns the filtered data set for display by the display control. Desirably, new filter criteria are passed to the data provider as they are being typed by the user, allowing the data provider to return successively smaller sets of result data, thus giving the visual impression of a shrinking data set.

Abstract: A device is provided for the treatment of teeth including an outer layer of non-porous polymeric material forming a trough, an inner layer forming an inner lining of the trough, and a treatment layer including a treatment agent disposed between the outer layer and the inner layer. The inner layer allows penetration of the treatment agent through after an aqueous solution is introduced to the device. A device is provided for the treatment of teeth including an outer layer of non-porous polymeric material in the form of a trough, wherein the trough has an outside and an inside surface. An outer lining layer is proximate to the inside surface of the outer layer; the outer lining layer includes a material for retaining a treatment agent. An inner lining layer forms an inner lining of the trough, wherein the inner lining layer includes a water-permeable material. A treatment layer is disposed between the inner lining layer and the outer lining layer, wherein the treatment layer includes a treatment agent.

Abstract: An automatic control system for a papermaking machine having a plurality of variable dewatering devices with moveable elements which engage the conveyor carrying the paper stock and are adjusted by electrical operating devices, such as servo motors or solenoid valves, to vary their water removal rate in response to control signals produced by a computer controller. A plurality of sensors are spaced along the path of the paper sheet downstream from the variable dewatering devices to sense the paper sheet characteristics including light transparency and mass, and to apply sensor output signals corresponding thereto to the computer controller. The servo motors have their shafts coupled to adjustment devices for cam mechanisms which adjust the moveable elements of the variable dewatering elements.

Abstract: Nucleic acid molecules encoding an enzyme involved in very long chain fatty acid (VLCFA) elongation in plants are disclosed. The invention includes a cDNA, genomic clone and encoded protein, as well as plants having modified VLCFA composition, such as modified epicuticular waxes, and methods of making such plants.

Abstract: The scripting engine interface provides the capability to interconnect any suitably written application or server with any scripting language. The implementation of the scripting engine itself (language, syntax, persistent format, execution model, and the like) is left entirely to the vendor, and the scripting engine need not come from the same vendor as the host application. The scripting engine interface implements this capability using a set of interfaces, the two most important ones being IActiveScriptSite (implemented by the host application) and IActiveScript (implemented by the language engine.) Together, these interfaces allow a host application to inform a scripting engine about the functionality that can be scripted and to define the scripts that the scripting engine should execute, either immediately or in response to user actions such as mouse clicks.

Abstract: Various enhancements are provided to a pushbutton lock to enhance its security. One is the provision of button tips that are mounted on the ends of the button assemblies and spring-loaded to protrude from the face of the lock, regardless of whether the underlying button is “in” or “out.” By this arrangement, a bystander cannot readily see the button combination by the pattern of depressed buttons. This arrangement also reduces tactile feedback between the underlying button assembly and the externally available button tips, increasing resistance to pick attacks. A further enhancement is the provision of button bars between adjacent pairs of button tips. Whenever any of the button tips is manually depressed, the corresponding button bar is pressed into engagement with, and prevents movement of, a member that must be moved in order to unlock the lock.

Abstract: Methods and apparatus are disclosed for detecting a thickness of a surficial layer (e.g., metal or insulating layer) on a workpiece (e.g., semiconductor wafer) during a process for planarizing the layer, so as to stop the process when a suitable process endpoint is reached. Layer thickness is detected based on a spectral-characteristic signal of reflected or transmitted signal light, obtained by directing a probe light onto the surface of the workpiece. Example spectral characteristics are local maxima and minima of signal-light waveform, differences or quotients of the same, a dispersion of the signal-light waveform, a component of a Fourier transform of the signal waveform, a cross-correlation function of the signal waveform. Alternatively, the zeroth order of signal light is selected for measurement, or a spatial coherence length of the probe light is compared with the degree of fineness of the pattern on the surface illuminated with the probe light.

Abstract: Two-domain MHC polypeptides useful for manipulation of antigen-specific T-cells are disclosed. These polypeptides include MHC class II-based molecules that comprise covalently linked &bgr;1 and &agr;1 domains, and MHC class I-based molecules that comprise covalently linked &agr;1 and &agr;2 domains. These polypeptides may also include covalently linked antigenic determinants, toxic moieties, and/or detectable labels. The disclosed polypeptides can be used to target antigen-specific T-cells, and are useful, among other things, to detect and purify antigen-specific T-cells, to induce or activate T-cells, and to treat conditions mediated by antigen-specific T-cells.

Abstract: Herpesvirus preparations, e.g. cultured HSV type 2, e.g. genetically disabled virus for vaccine use, can be purified, e.g. for subsequent pharmaceutical formulation, with solid phase affinity reagents containing sulfate- or sulfonate-comprising binding groups, e.g. sulfated polysacharide groups, e.g. heparin or dextran sulfate, and eluting e.g. with salt solutions. The process can be combined with other culture and harvesting steps.

Abstract: A server application associated with a document provides a document object with a print interface to support programmatic document printing. A client application interacts with the document object through the print interface to control printing. The print interface supports progress monitoring and print cancellation during printing using a call back interface of the client program. The print interface also supports opaquely conveying document-specific print options, so that the client program can perform subsequent print operations with the same or similar document object using the same print options without the client program manipulating the print options. The document object also has a print preview interface which supports programmatic print previewing.

Abstract: A stairway assembly is pivoted between deployed and stowed positions. The stairway in one form includes a sliding support from which the stairway is suspended at a location spaced from a stairway pivot. A link, which may be adjustable in length, couples the coupler to the stairway. A snubber is provided to limit vibration of the stairway when stowed. An actuator, which may comprise an electric motor, is positioned above and overlies a portion of a platform of the stairway. Extension and retraction of the actuator pivots the stairway between stowed and deployed positions.
