  • Patent number: 9237934
    Abstract: A stethoscope disinfection system comprising a guide member comprising a body member, a rotation-imparting member, a slide guide track, a spring guide track, and a trolley guide track, and a trolley comprising a lower housing member, a cam member, a lock head, a spring apparatus, a brush member, an upper housing member configured to receive at least a portion of a head of a stethoscope, and a dispersing member positioned in the dispersing mechanism chamber. The system may further comprise a slide guide configured to engage with each of the arm of the lock head and the slide guide track and to translate along a length of the slide guide track.

  • Patent number: 7783098
    Abstract: A method including acquiring images of medical slides at a plurality of different focus positions, determining a position which produces a maximum value of pixel values relative to a pixel value mean, wherein said determining comprises using a pixel value mean as a coarse estimate of coarse focus position, and subsequently refining said coarse focus position to find a fine focus position, and wherein said refining comprises fitting to a polynomial, and using a specified portion of the polynomial as a fine estimate of focus position, and producing a focus control signal that is related to said maximum value to control a focus position.

  • Publication number: 20080258061
    Abstract: An electronic microscope system including a processor, a movable stage movable in two orthogonal directions under control of the processor, the movable stage including at least one part that determines a current position of the movable stage, a microscope part, which magnifies a sample on the movable stage, an electronic camera part, which obtains an image of a magnified sample at a specified position controlled by the movable stage, and at least one vibration isolation mount, coupled to the stage and isolating vibration between the movable stage and the microscope part.

  • Patent number: 7428325
    Abstract: A method and apparatus for automated cell analysis of biological specimens automatically scans at a low magnification to acquire images which are analyzed to determine candidate cell objects of interest. The low magnification images are converted from a first color space to a second color space. The color space converted image is then filtered. The candidate interest pixels are morphologically processed and compared to blob parameters to identify candidate objects of interest which correspond to cells or other structures relevant to medical diagnosis of the biological specimen. The location coordinates of the objects of interest are stored and additional images of the candidate cell objects are acquired at high magnification.

  • Patent number: 7359548
    Abstract: A method and apparatus for automated cell analysis of biological specimens automatically scans at a low magnification to acquire images which are analyzed to determine candidate cell objects of interest. The low magnification images are converted from a first color space to a second color space. The color space converted image is then low pass filtered and compared to a threshold to remove artifacts and background objects from the candidate object of interest pixels of the color converted image. The candidate object of interest pixels are morphologically processed to group candidate object of interest pixels together into groups which are compared to blob parameters to identify candidate objects of interest which correspond to cells or other structures relevant to medical diagnosis of the biological specimen. The location coordinates of the objects of interest are stored and additional images of the candidate cell objects are acquired at high magnification.
