  • Patent number: 8067245
    Abstract: An apparatus and method of automated blood cell analysis uses technologies from other systems to create a new, robust, improved type of automated microscope, which uses electronic motors and a closed loop control system to minimize ambient factors, such as jarring and temperature changes. Pre-stained blood smear slides are first coated with a thin film of oil and are loaded into a carousel from which they can individually be analyzed. The slides are moved under a low magnification microscope; an optimal area of examination is determined; a focal plane map is calculated for that area, and the positions of white blood cell candidates are computed. The slide is then moved under a high power microscope where a refined focal plane map is computed and the individual white blood cell candidates are imaged. The cells are preclassified and the images are made available for analysis by the technician.

  • Publication number: 20110222081
    Abstract: Methods of how to build a 3D model with both surface features and internal structures are disclosed. 3D image data in a hybrid data format or other suitable data formats are first received as input and then broken down into layers of 2D data. The layers of 2D data hold various attribute information about the model, such as colors, shapes, durometer hardness, etc. The layers of data are printed on printing sheets that are specially formulated. Selected materials are also deposited on printed sheets as dictated by the 2D data. Each printed sheet is cut along the shape boundaries either before or after it has been bound to previously printed sheets. Finished sheets are then bound and processed to generate a 3D model with rich details.
