| 20110005250 | Switching pressure regulator - A system for converting gas flowing at variable flow rates and pressure to gas flow at a load dependent flow rate and a regulated pressure. A valve member operable in only two stable states (fully open and closed) by valve actuation means, said valve actuation means being interposed between an input manifold adapted to carry volumes of gas flow at variable flow rates and pressure and an output manifold adapted to carry gas flow at a predetermined constant pressure; a reservoir/accumulator in open connection to said output manifold for temporary storage of portions of said gas flowing through said output manifold; pressure sensing means for monitoring the pressure of the gas flow through said output manifold; and electronic processing means connected to said gas pressure sensing means for activating said valve actuation means in one of its two bi-stable states, depending upon the gas pressure sensed in said output manifold. | 01-13-2011 |

| 20090087051 | Image Quality for Diagnostic Resolution Digital Slide Images - An improved diagnostic resolution of digital slide images is obtained by scanning a first digital slide image at diagnostic resolution that is then deconvolved into separate images with one stain per image. The single stain images are then enhanced with image adjustments and/or processed with image analysis algorithms. The resulting single image data sets from the image analysis algorithms can then be stored. Additionally, the resulting enhanced single images can be recombined into a second digital slide image at diagnostic resolution that is also enhanced. | 04-02-2009 |

| 20110115897 | Whole Slide Fluorescence Scanner - A whole slide fluorescence digital pathology system is provided that uses a monochrome TDI line scan camera, which is particularly useful in fluorescence scanning where the signal is typically much weaker than in brightfield microscopy. The system uses oblique brightfield illumination for fast and accurate tissue finding and employs a unique double sweep focus scoring and objective lens height averaging technique to identify focus points and create a focus map that can be followed during subsequent scanning to provide autofocusing capability. The system also scans and analyzes image data to determine the optimal line rate for the TDI line scan camera to use during subsequent scanning of the digital slide image and it also creates a light profile to compensate for loss of illumination light due to roll off. | 05-19-2011 |

| 20100040266 | System for and method of intelligently directed segmentation analysis for automated microscope systems - The present disclosure includes systems and techniques relating to intelligently directed segmentation analysis for automated microscope systems. In general, in one implementation, the technique includes obtaining an image of at least a portion of a scan region including a biological specimen, partitioning the obtained image into zelles, determining one or more parameters of the zelles, performing a cluster analysis on the one or more parameters of the zelles, differentiating tissue of greater interest from tissue of lesser interest in the obtained image based on the cluster analysis and based on a test being performed for the biological specimen, and storing more information for the tissue of greater interest than information for the tissue of lesser interest. The cluster analysis can be a multivariate statistical cluster analysis, and the zelles can be test-dependent zelles (e.g., having dimensions defined according to the test being performed for the biological specimen). | 02-18-2010 |
| 20100141682 | Silhouette image acquisition - Systems and techniques to acquire image data. In general, in one implementation, the technique includes: acquiring image data for a plurality of areas of a scan region. The technique may further include processing the image data to determine whether an area includes one or more desired features. The technique may further include designating an area as “interesting” if it includes a desired feature, and designating an area as non-interesting if it does not include the desired feature. The areas may be sub-divided one or more times, and subdivisions may be analyzed to determine if they include a desired feature. | 06-10-2010 |
| 20100265323 | SYSTEM FOR AND METHOD OF FOCUSING IN AUTOMATED MICROSCOPE SYSTEMS - The present disclosure includes systems and techniques relating to focusing in automated microscope systems. In general, in one implementation, the technique includes obtaining an image of at least a portion of a scan region, analyzing the image to find an area in the image representing a sample, determining a nature of the sample at a selected focus point location in the area in the image, selecting an automated focusing process for use at the selected focus point location based on the determined nature of the sample at the selected focus point location, and focusing the selected automated focusing process. The selecting can include selecting different automated focusing processes for different focus point locations based on different tissue characteristics at the locations. | 10-21-2010 |

| 20100108927 | SILENT SOLENOID VALVE FOR FLUID REGULATION SYSTEM - A fluid regulator system includes at least one solenoid valve for interrupting flow of the fluid. The solenoid valve solenoid valve includes a plunger that is actuated by a solenoid, i.e., a coil. A plunger stop limits movement of the plunger when the solenoid is energized. A recess defined a top of the plunger. A plunger bumper assembly is disposed at least partially within the recess of the top of the plunger and at least partially between the top of the plunger and the plunger stop. The plunger bumper assembly includes a resilient component formed of a resilient material for dampening noise produced by a contact between the plunger bumper assembly and the plunger stop. | 05-06-2010 |

| 20110249844 | METHODS AND APPARATUS FOR IMPROVED NOISE REDUCTION FOR HEARING ASSISTANCE DEVICES - Disclosed herein, among other things, are methods and apparatus for improved noise reduction for hearing assistance devices. In various embodiments, a hearing assistance device includes a microphone and a processor configured to receive signals from the microphone. The processor is configured to perform noise reduction which adjusts maximum gain reduction as a function of signal-to-noise ratio (SNR), and which reduces the strength of its maximum gain reduction for intermediate signal-to-noise ratio levels to reduce speech distortion. In various embodiments, the hearing assistance device includes a memory configured to log noise reduction data for user environments. Also provided are methods to further adjust the noise reduction based on the logged information. | 10-13-2011 |
