  • Patent number: 8993914
    Abstract: A high-speed, high-resolution, triangulation-based, 3-D method and system for inspecting manufactured parts and sorting the inspected parts are provided. The method includes consecutively transferring the parts so that the parts move along a path which extends from a supply of parts and through an imaging station. A triangulation-based sensor head is supported at the imaging station. The sensor head is configured to generate focused lines of radiation and to sense corresponding reflected lines of radiation. The focused lines are delivered onto an end surface of each part to obtain a corresponding array of reflected lines of radiation. The sensor head senses the array of reflected lines to obtain a corresponding set of 2-D profile signals. The set of profile signals represent a 3-D view of the end surface. The set of 2-D profile signals of each part is processed to identify parts having an unacceptable defect.

  • Publication number: 20140251880
    Abstract: A laser-based mono-energetic gamma-ray source is used to provide a rapid and unique, isotope specific method for sorting materials. The objects to be sorted are passed on a conveyor in front of a MEGa-ray beam which has been tuned to the nuclear resonance fluorescence transition of the desired material. As the material containing the desired isotope traverses the beam, a reduction in the transmitted MEGa-ray beam occurs. Alternately, the laser-based mono-energetic gamma-ray source is used to provide non-destructive and non-intrusive, quantitative determination of the absolute amount of a specific isotope contained within pipe as part of a moving fluid or quasi-fluid material stream.

    Abstract: A piece of material that includes low-Z elements is classified based on photonic emissions detected from the piece of material. Both XRF spectroscopy and OES techniques, for example, Laser-Induced Breakdown Spectroscopy (LIBS) and spark discharge spectroscopy, may be used to classify the piece of material. A stream of pieces of material are moved along a conveying system into a stimulation and detection area. Each piece of material, in turn, is stimulated with a first and second stimulus, of a same or different type, causing the piece of material to emit emissions, for example, photons, which may include at least one of x-ray photons (i.e., x-rays) and optical emissions. These emissions then are detected by one or more detectors of a same or different type. The piece of materials is then classified, for example, using a combination of hardware, software and/or firmware, based on the detected emissions, and then sorted.

  • Patent number: 7170970
    Abstract: The concentration(s) of element(s) contained in an unknown sample is measured without necessity of judging the sample relying on a human's eye and obtaining information from a supplier of the sample previously. The concentration(s) of trace element(s) such as Cd, Pb and Hg contained in parts for electronic or electric equipment is determined by (1) irradiating the sample with an X-ray so as to identify whether the type of the sample is a nonmetal-based material or a metal-based material; (2) selecting measuring conditions for a fluorescent X-ray analysis depending on the identified type of the sample; and (3) measuring the concentration(s) of one or more element(s) contained in the sample by the fluorescent X-ray analysis according to the selected measuring conditions.

  • Patent number: 6778681
    Abstract: Systems and methods for non-intrusive analysis and display of internal features of wooden objects are provided. In embodiments of the system, a log is passed through a CT scanner in one continuous motion. One or more x-ray sources revolve around the log generating x-ray beams that traverse contiguous cross-sections of the log. An array of x-ray detectors detects x-rays that traverse the log for variations in the attenuation of rays. The detected attenuation is converted into spiral scan data that corresponds to projections in different contiguous cross-sections traversed by the x-rays. An image processor reconstructs spiral scan data into two dimensional cross-sectional images of the log by processing and formatting scan data using a planar reconstruction technique. The system renders three-dimensional views based on two-dimensional images.
