摘要:
Described are tunable multiport optical filters that filter systems with many optical channels in a convenient and cost-effective manner. The tunable multiport optical filters of the invention are simple in design and have few optical components. The basic elements are a dispersion element and a rotating reflector. With properly arranged arrays of input and output optical fibers, individual wavelength components from a selected input beam are spatially separated and steered by the rotating reflector to selected output locations. The optical properties from the selected components may be measured by one or more photodetectors. The filters are also useful for selecting and routing optical signals.

The tunable multiport optical filters of the invention are simple in design and have few optical components. The basic elements are a dispersion element and a rotating mirror.

A process for making highly mechanical and chemical resistant ceramic substrates, especially tiles is provided, wherein the process comprises coating said substrates with a base coat layer of a thermosetting or radiation curable powder coating composition, curing the applied powder coating composition, and applying a further layer of a liquid coating composition and curing the composition by exposure to heat. Coated ceramic substrates, in particular tiles are also provided.

Architecture employs an iterative process that incrementally discovers inter-component interactions and explores local state spaces within each component. Thus, the architecture lazily constructs the behavior of the environment of a component in the target software system, and integrates the construction of the inter-component interactions with the model checking process itself, and hence, does not need to eagerly construct the interface process. Component-based state space reduction is applied during the exploration of the whole system. The architecture decomposes a target software system into a set of loosely coupled components where interactions between the components tend to be significantly simpler than interactions within each component. An iterative algorithm facilitates the component-based state space reduction, which is exponential, on the real large-scale software systems.

A device, system, and method for providing access to, and sealing of, a body organ includes an implant device. An implant device has a main body having an internal access lumen, with a plurality of prongs extending from a distal end of the main body. The main body can include two lumens, one slidable within the other, to form a single continuous lumen with an adjustable length. The main body has an expanded configuration with an expanded diameter, and an unexpanded configuration with an unexpanded diameter. The prongs have a generally straight configuration where they extend distally of the distal end of the main body, and a bent configuration where the prongs bend around so that their tips extend proximally of the distal end of the main body. The device may include a hemostatic barrier to prevent fluid leakage therethrough when the main body is in the unexpanded configuration.

An operating system installation method appended with driver programs and related structure is disclosed. The structure, and the method as well, is applied to a computer equipment for appending driver programs needed by hardware units of the computer equipment in an original operating system installation program. The structure includes a loading module, an acquiring module and a mapping module. The method loads an operating system installation into a memory of the computer equipment, maps the driver programs onto system kernel parameters of the operating system installation program to update the operating system installation program, and burns the updated operating system installation program onto a disk, so as to generate an operating system installation disk suit for the hardware units of the computer equipment.

The invention provides a set of highly orthogonal six-code universal sequences for use in bDNA singleplex and multiplex nucleic acid hybridization assays. The six-code orthogonal sequences do not cross-hybridize and thus, minimize or eliminate the 3-mer cross-hybridization inherent in the second and third generation bDNA assays. The highly orthogonal universal sequences may be used in singleplex or multiplex bDNA assays quantitatively and qualitatively to determine mRNA levels in a sample; to screen for and genotype targets, such as viruses, that are present in low volumes in a sample; to screen for and genotype SNPs; and to measure changes in the amount of a gene in a sample such as when gene amplifications or deletions occur. The highly orthogonal universal sequences may also be used as universal capture probes to selectively bind assay components in a way that facilitates their further analysis.
