    Abstract: An integrated technological platform enabling real-time quantitative multiparameter metabolic profiling, utilizing either or both of extra and intracellular optical sensors, individually or simultaneously. A scalable embedded micropocket array structure, generally fabricated on fused silica substrates, facilitates the integration of multiple, spatially separated extracellular sensors for multiparameter analysis in a container formed with the use of an activation mechanism forming part of a device configured to hold the container during the measurements. The creation of hermetically sealed microchambers is carried out with a pneumatically and/or mechanically and/or electromechanically driven device that is “floating” within the holding device and that is optionally equipped with a vacuum/suction mechanism to hold a component of the container at its surface.

  • Patent number: 7813537
    Abstract: Myocardial tissue tracking techniques are used to project or guide a single manually-defined set of myocardial contours through time. Displacement encoding with stimulated echoes (DENSE), harmonic phase (HARP) and speckle tracking is used to encode tissue displacement into the phase of complex MRI images, providing a time series of these images, and facilitating the non-invasive study of myocardial kinematics. Epicardial and endocardial contours need to be defined at each frame on cine DENSE images for the quantification of regional displacement and strain as a function of time. The disclosed method presents a novel and effective two dimensional semi-automated segmentation technique that uses the encoded motion to project a manually defined region of interest through time. Contours can then easily be extracted for each cardiac phase.

  • Patent number: 7700916
    Abstract: A navigation system for easily determining defective positions is provided. In the case of CAD navigation to defective positions, logical information for indicating defective positions is created in a CAD format, instead of CAD data of physical information indicating circuit design. Specifically, by attaching marks such as rectangles, characters, or lines, to an electron microscope image with software, quick navigation is performed with required minimum information. By using created CAD data, re-navigation with the same equipment and CAD navigation to heterogeneous equipment are performed.

  • Patent number: 7573586
    Abstract: A method of measuring a coating thickness involves projecting a pattern of light on a surface. A first reflection of the pattern of light is received by a first image capturing device. A second reflection of the pattern of light is received by an image capturing device which may be the same or a different image capturing device. The first reflection is compared with the second reflection. A first dated map of the surface is created by comparing the first reflection and the second reflection. A coating is deposited on the surface. A second data map of the surface with the coating is created by comparing reflections. The first data map and the second data map are then compared to determine a thickness of the coating.

  • Patent number: 7433032
    Abstract: In a method of inspecting defects, a first actual region of an actual object is inspected based on a first characteristic parameter as an inspection condition. A point where an inspection region of the actual object is changed into a second actual region from the first actual region is determined. The second actual region is then inspected based on a second characteristic parameter as the inspection condition. The first and second parameters may include contrast of a light that is reflected from a reference object, intensity of the light, brightness of the light, a size of a minute structure on the reference object, etc. The characteristic parameters of each reference region on the reference object are set. Thus, the defects may be accurately classified so that a time and a cost for reviewing the defects may be markedly reduced.

  • Patent number: 7403872
    Abstract: A method and system are provided for inspecting manufactured parts such as cartridges and cartridge cases and sorting the inspected parts. The system includes an illumination assembly for evenly illuminating a plurality of annular, exterior side surfaces of a part when the part is located in a circumference vision station with rings of strobed radiation to generate corresponding reflected radiation signals. A plurality of imaging detectors in the form of CCD cameras are located at the vision station to generate a plurality of side images. The system further includes at least one side image processor for processing the side images of each part to identify parts having an unacceptable defect. The system further includes a mechanism for directing parts identified as having an unacceptable defect to a defective part area and directing parts not identified as having an unacceptable defect to an acceptable part area.

  • Patent number: 7225051
    Abstract: A method and system for maximizing process capability in a progressive forming operation. The method compensates for deviations introduced by unformed components, and uses closed loop feedback to compensate for deviations introduced by forming tools. Fiducial features are detected on an incoming component, and a first compensation value is calculated from displacement of the fiducial features from an ideal forming location on the component. Component position with respect to a theoretical forming position is adjusted according to the first compensation value. Placement of a feature formed on the component at the adjusted position is detected and compared to the ideal forming location to obtain a difference value. A second compensation value is derived from a plurality of difference values. Forming positions for subsequent incoming components are adjusted with respect to the theoretical forming position according to first and second compensation values.

  • Patent number: 7110036
    Abstract: Systems and methods for identifying an interchangeable lens in a vision system having a controllable light source, a camera, and the lens to be identified. Light provided by the light source is transferred to the camera by the lens to be identified. The amount of light transferred to the camera for a particular reference configuration of the vision system depends distinguishably on the characteristics of the lens to be identified. A camera output is measured for a desired light source setting and the desired light source setting and associated measured camera output are compared with stored lens identification calibration data. The stored lens identification calibration data is obtained by measuring the camera output for a plurality of lenses using a plurality of light source settings. In various exemplary embodiments, the light transferred from the light source to the camera is reflected and/or backscattered light from the lens to be identified.

  • Publication number: 20040154402
    Abstract: The invention is directed to an ultrasonic testing system. The system tests a manufactured part for various physical attributes, including specific flaws, defects, or composition of materials. The part can be housed in a gantry system that holds the part stable. An energy generator illuminates the part with energy and the part emanates energy from that illumination. Based on the emanations from the part, the system can determined precisely where the part is in free space. The energy illumination device and the receptor have a predetermined relationship in free space. This means the location of the illumination mechanism and the reception mechanism is known. Additionally, the coordinates of the actual testing device also have a predetermined relationship to the illumination device, the reception device, or both.
