  • Publication number: 20240169519
    Abstract: A system and method for rendering an interactive display that is used by a pathologist to review a specimen slide. The system renders a series of slides that contain all the information on a digitized slide and presents the tiles in a linear fashion in order of diagnostic significance. Additionally, tiles containing cells having a high degree of abnormality are provided with images of neighboring cells/tissue so that a reviewing pathologist is provided with context which is beneficial for a determination of abnormality.

  • Publication number: 20240046419
    Abstract: A system and method for constructing a digital composite image of a three- dimensional biological sample. The system includes an optical system that captures images of cells and tissue presented on a specimen slide. The system systematically acquires a stack of images at different segments across the specimen slide. For each segment, the system dynamically calculates an optimal focal plane. Once an optimal focal plane is determined for each of the stacks of images, the system generates a composite image by copying the sharpest objects from each of the optimal focal planes.

  • Patent number: 8199997
    Abstract: A method and system for constructing a digital image of a three-dimensional biological specimen that displays diagnostically important information—substantially to the exclusion of unimportant information. The system de-enhances features in a cellular specimen which are not diagnostically important and enhances those which are. The system selects the sharpest pixel for each pixel location from among a stack of image slices and copies them into a composite image.

  • Patent number: 7503720
    Abstract: A holder for a panel, such as a light cover in an aircraft, is provided. A mounting section, a shoe receiving section and a pin provide a pin and shoe operation, such that a shoe is slideable onto the shoe receiving section in an open position of the holder, and such that the mounting section and the shoe receiving section are attached to each other by the pin in a closed position for securing the shoe in the holder. A recess or aperture is positioned in the shoe receiving section to receive the pin.

  • Patent number: 6186235
    Abstract: A preferred novel breaker-crosslinker-polymer complex and a method for using the complex in a fracturing fluid to fracture a subterranean formation that surrounds a well bore by pumping the fluid to a desired location within the well bore under sufficient pressure to fracture the surrounding subterranean formation. The complex may be maintained in a substantially non-reactive state by maintaining specific conditions of pH and temperature, until a time at which the fluid is in place in the well bore and the desired fracture is completed. Once the fracture is completed, the specific conditions at which the complex is inactive are no longer maintained. When the conditions change sufficiently, the complex becomes active and the breaker begins to catalyze polymer degradation causing the fracturing fluid to become sufficiently fluid to be pumped from the subterranean formation to the well surface.

  • Patent number: 5655029
    Abstract: A device for the visual inspection of a specimen, comprising a first microscope for obtaining a magnified view of different areas of a specimen, a display monitor for displaying images of at least a subset of the different areas of the specimen, selection means for enabling the selection of a image displayed on the monitor, a second microscope for review of an area of the specimen corresponding to the selected image, a motorized stage for positioning said specimen with respect to the field of view of the second microscope, and a processor for determining the image selected and instructing the motorized stage to position the specimen so that the area of the specimen corresponding to the selected image is in the field of view of the second microscope.
