Abstract: A particle concentrator, having a top and a bottom and including a hollow outer hub, having a top and bottom and bottom wall, and a side wall defining a plurality of sampled airflow inlet slots. An inner hub is placed in the outer hub and has a hollow interior, and which for each one of the sampled airflow inlet slots, supports a blade defining a secondary airflow slot aligned to a sampled airflow inlet slot, is sealed at its top, and is in fluid communication with the hollow interior of the inner hub, and wherein each adjacent two blades define a space between blades. A fan assembly is for blowing air out of the top of the outer hub, from the spaces between blades, causing air inflow through the sampled airflow inlet slots, some air then flowing into the secondary airflow slots, where it flows into the inner hub.

Abstract: A concentrator, wherein the concentrator comprises an air processor that includes a sampled airflow inlet slot that receives a sampled airflow that contains particles containing target material. A secondary airflow inlet slot that is located downstream from the sampled airflow inlet slot. The sampled airflow inlet slot uses centrifugal force to concentrate particles containing target material into a central portion of the sampled airflow, and produces a non-collimated sampled airflow. The secondary airflow inlet slot is operable to divide a secondary airflow from at least a part of the central portion of the sampled airflow that is received by the secondary airflow inlet slot from the sampled airflow inlet slot, and is operable to divide side primary airflows from the non-collimated sampled airflow produced by the sampled airflow inlet slot. Finally, the secondary airflow flows through the secondary airflow inlet slot.

Abstract: A concentrator that is operable to concentrate particles of target material from a high flow rate sampled airflow into a low flow rate secondary airflow. The concentrator may have an array of radially arranged blades. Each blade may have a sampled airflow inlet that uses centrifugal force to concentrate the particles into a central portion of the sampled airflow passing through it. Downstream, the blade may also have primary airflow outlets and knife-edged secondary airflow inlets that divide the sampled airflow into a pair of lateral, high flow rate primary airflows from which the particles have been depleted, and a central, low flow rate secondary airflow which carries the concentrated particles.

Abstract: A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Abstract: A task light system for a surgical console includes a task light that can be held to a coupling location on a surgical console. The task light has an inductive coupling, a light source, and a goose neck connecting the light source to the inductive coupling. The coupling location is located on a face of the surgical console. The coupling location is configured to magnetically attract and hold the inductive coupling. The face of the surgical console where the coupling location is located is a continuous surface.

Abstract: Disclosed are mutated genes for green fluorescence proteins and enhanced inserted YFPs expressed therefrom. The mutant proteins not only maintain their fluorescence even at 37° C., but also exhibit about 20 times stronger fluorescence intensities in comparison to the conventional fluorescence proteins. Accordingly, the mutant fluorescence proteins of the present invention can be used as biosensors for detecting and analyzing the bioactivities of desired materials.

Abstract: Disclosed are the methods for producing recombinant viruses using site-specific recombination in vitro. In the present invention, circular viral genomic DNAs are digested with restriction enzymes to generate a linear form viral genomic DNAs flanked by site-specific recombination sites, and then are subjected to site-specific recombination with the desired genomic materials flanked by site-specific recombination sites in vitro. According to the present invention, since the site-specific recombination mixture can be applied to host cells without further procedures of selecting the desired recombinant viral genomic DNAs, it is possible to obtain numerous recombinant viruses rapidly at the same time. Thus, the present invention can be used as a high throughput system for generating and screening hundreds or thousands of recombinant viruses.

Air flow through the air sampler may be generated by a fan that is either external or internal with respect to the main body's cyclonic cup. A thin film of stripping liquid and/or a fog of stripping liquid particles in the air inlet tube, the cyclonic cup, the stripping column and/or the demister strip a target material from the air flow through the air sampler. A passive fog generating slot or a passive spiral fog generating nozzle may be placed over the fluid input conduit in the center of the cyclonic cup. The air sampler's main body and/or an air inlet tube may be integrally formed as one part.
