| 20110139620 | MICROFLUIDIC CELL - A microfluidic cell for the dielectrophoretic separation, accumulation, and/or lysis of polarizable bioparticles, including an interdigital electrode system composed of two electrode groups having interdigitated electrodes, and a micromixer having microchannels and microelevations. The interdigital electrode system and the micromixer are situated on the same side of the cell to improve the separation, accumulation, and/or lysis characteristics. Moreover, also described is a microfluidic system which includes such a microfluidic cell, and use thereof, and a method for separating, accumulating, and/or lysing polarizable bioparticles. | 06-16-2011 |
| 20110139621 | MICROFLUIDIC CELL - A microfluidic cell for the dielectrophoretic separation, accumulation, and/or lysis of polarizable bioparticles, including an interdigital electrode system composed of two electrode groups having interdigitated electrodes, a flat electrode in which the interdigital electrode system and the flat electrode are situated on opposite sides of the cell in order to improve the separation, accumulation and/or lysis characteristics. Moreover, a microfluidic system which includes such a microfluidic cell, and use thereof, and a method for separating, accumulating, and/or lysing polarizable bioparticles is also described. | 06-16-2011 |

| 20090086311 | Spectral Filtering Method and Apparatus in Optical Parametric Chirped Pulse Amplification - Method and apparatus embodiments of the invention are directed to mitigating temporal contrast degradation in optical parametric chirped pulse amplification (OPCPA) laser systems. A spectral filter is used in an OPCPA laser system to remove or reduce of out-of-band amplified spontaneous emission (ASE) from an amplified pump pulse and/or the longitudinal modes of a seed laser used to generate the pump pulse, which typically cause detrimental temporal intensity fluctuations in the amplified pump signal. According to an illustrative embodiment, a volume Bragg grating (VBG) filter element is disposed in the pump regenerative amplifier cavity where the pump pulse undergoes multiple passes on the filter element. | 04-02-2009 |

| 20090006969 | Video microscopy system and multi-view virtual slide viewer capable of simultaneously acquiring and displaying various digital views of an area of interest located on a microscopic slide - A slide viewer capable of simultaneous display of more than one representation of an area of interest of a slide is provided. The slide viewer includes a database containing at least two data files representing different representations for a same area of interest on one or multiple correlated slides or at least two different digital presentations of the same representation. The representations are views of different illumination and/or of different contrast. Associated with the database are a processor and a display. The processor retrieves data files representing different representations of the same of area of interest and displays them on the display. A user is allowed to simultaneously view representations of the same area of interest, where the representations are of views different from each other by either illumination and/or contrast or by the digital information content presented, and/or by the information acquired from multiple correlated slides. | 01-01-2009 |
| 20090196526 | MICROSCOPY SYSTEM HAVING AUTOMATIC AND INTERACTIVE MODES FOR FORMING A MAGNIFIED MOSAIC IMAGE AND ASSOCIATED METHOD - A scanning device for biological slides is provided, which can be operated in an interactive routine mode as well as in an unsupervised high speed automatic mode. In the first case, typical components, which the pathologist is used to operating manually, such as the microscope, the stage and the focus, and which have to be motorized for the automatic unsupervised system mode, are configured to simulate manual use, operation, and response. A non-interlaced area scan camera supports the interactive selection and acquisition of individual images in the manual mode, as well as the continuous high-speed scan motion for the rare event detection and virtual slide scan applications of the system. Due to the particular requirements to accommodate both operational modes, methods are described for constructing the virtual slide out of image tiles with varying overlap areas in the x- and y-directions. | 08-06-2009 |
