A multi-flash photography system provides a dynamically-configurable lighting environment for a single exposure that is created and shaped through the sequentially firing of various light sources with different lighting characteristics controlled in accordance with both a programmed template specifying the flash type, position, firing order, and output intensity, as well as optical processing requirements such as filtering, polarizing, etc., and a shared photometric detector located sufficiently close to the subject being photographed to ensure that the light seen by the detector is substantially the same as the light received at the subject.

The present invention relates to methods for synthesizing conformationally constrained peptides and cyclic peptidomimetics obtainable by these methods which are conformationally constrained due an internal cross-link. This cross-link is formed between the side chain of an amino acid residue or analog and a (2S, 4S)4-functionalized proline residue. The invention further relates to the use of (2S, 4S)-4-functionalized proline residues as building units in the synthesis of such peptidomimetics and to the use thereof as antigens, alone or in combination with suitable immunopotentiating delivery systems, for example immunopotentiating reconstituted influenza virosomes to elicit an immune response in a mammal. Moreover, the invention also relates to pharmaceutical compositions containing the same.

An assembly comprises a part for example a part of an item of cookware, bakeware, domestic appliance or the like which is subjected to a wear means in use such that the wear means may abrade the outer surface of the part. The part is provided with an outer surface which comprises a polyaryletherketone polymer, especially polyetheretherketone, and a fluoropolymer. Such a combination is found to exhibit superior wear properties over other known materials.

A method for optimizing alignment performance in a fleet of exposure systems involves characterizing each exposure system in a fleet of exposure systems to generate a set of distinctive distortion profiles associated with each exposure system. The set of distinctive distortion profiles are stored in a database. A wafer having reference pattern formed thereon is provided for further pattern fabrication and an exposure system is selected from the fleet to fabricate a next layer on the wafer. Linear and higher order parameters of the selected exposure system are adjusted using the distinctive distortion profiles to model the distortion of the reference pattern. Once the exposure system is adjusted, it is used to form a lithographic pattern on the wafer.

Disclosed are apparatus and methods for obtaining and analyzing various unique metrics or “target diagnostics” from one or more semiconductor overlay targets. In one embodiment, an overlay target is measured to obtain one or both of two specific types of target diagnostic information, systematic error metrics and/or random noise metrics. The systematic error metrics generally quantify asymmetries of the overlay target, while the random noise metrics quantify and/or qualify the spatial noise that is proximate to or associated with the overlay target.

An electronic faucet includes a control that has at least three different modes of operation. The control has an auto or normal mode of operation where fluid flows for a predetermined amount of time when a sensor detects an object adjacent to the electronic faucet. The control has an “off” mode where system electronics are disabled such that fluid cannot flow, and the control has an “on” mode where fluid is constantly flowing. A mechanical or electronic selector is selectively actuated to place the control in one of the auto, off, or on modes.

A vending machine includes first and second integrated dispensing systems mounted at front portions of adjacent product shelf dividers establishing at least first, second and third product queues. Each of the first and second dispensing systems includes first and second release mechanisms having a plurality of hinged plates supported by a frame. The plurality of hinged plates are selectively shifted into and out of corresponding ones of the first, second and third product queues, such that each product queue has associated therewith two opposing release mechanisms. Preferably, at least one of the first and second release mechanisms for each dispensing system includes a queue spacing member which is mounted to one of the hinged plates and projects into the product queue to establish a desired spacing between the release mechanisms.

The invention relates to a system of shaft sealing for a turbine engine. Carbon-ring seals placed on pressurized bearing compartments are adapted to operate on ceramic runners which are cooled by lubricating fluid. The runners are closed at one end so that fluid does not enter an interface between the runner and the seal. The seal is held in place in a cylindrical seal housing with an inwardly projecting seal retention wall. An internally cooled seal housing is provided having an enclosed annular cooling groove is formed in the wall. Fluid is circulated through the groove to provide cooling of the seal housing and the carbon-ring seal. The circulated fluid is provided from the same source as fluid that is circulated to lubricate bearings on the engine. However, a separately controlled fluid delivery system is employed so that a rate of flow of fluid to the seal housing can be specifically controlled. Cooling effects of circulated fluid are made available to the seal housing even though there is no fluid directed at a shaft-seal interface. Undesirable churning and fluid loss also may be reduced.

Template-fixed β-hairpin peptidomimetics of the General Formula (I); wherein Z1 and Z2 are template-fixed chains of 4 and 6 or 5 and 7 α-amino acid residues which, depending on their positions in the chain are Gly, or Pro, or of certain types which, as the remaining symbols in the above formula, are defined in the description and the claims, and salts thereof, have the property to prevent or to reduce HIV infections or to inhibit the growth of cancer cells or to inhibit inflammation. They can be used as medicaments to treat or prevent HIV infections and/or cancer or inflammatory disorders. These β-sheet peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.
