  • Patent number: 8336365
    Abstract: Disclosed is a method and an NDT/NDI calibration process that automatically detects erroneous TOF readings by providing a predetermined time acceptance window. During the calibration process, TOF readings acquired by a UT device are validated to determine whether the TOF reading for the thin test block falls within the range of the predetermined time acceptance window. If the TOF reading for the thin block (T2) falls out of the predetermined time acceptance window, the operator is alerted of an error and to repeat the TOF test for the thin block.

  • Patent number: 8109134
    Abstract: In a method for determining the degree of hardening or drying of one or more printed ink and/or coating film(s) on a substrate, for instance, paper, cardboard, plastic film or composite materials, a faster and more efficient measuring method can be found that furthermore supplies secure and easily interpreted results. The method is to be used in the mass production printing processes comprising intaglio printing, flexographic printing, screen printing or offset printing. The degree of hardening or drying is determined indirectly by way of the change in the mechanical and/or viscoelastic properties of the ink and/or coating films on the substrate that result from the hardening or drying process. The detection of acoustic waves by means of a piezoelectric sensor is used as the measuring method.

  • Patent number: 8085403
    Abstract: Embodiments of the apparatus, systems, and methods relate to a photoacoustic sensor includes an excitation source, a modulator, a quantum dot filter, an interferometer, a gas chamber, and a microphone. The excitation source generates a monochromatic light. The modulator intensity modulates the monochromatic light at a first modulation frequency. The quantum dot filter down converts the modulated monochromatic light into a broadband spectrum of infrared light. The interferometer further intensity modulates the broadband spectrum such that the at least one wavelength component of the broadband spectrum is further intensity modulated at a second modulation frequency. The gas chamber stores a sample gas and receives the plurality of modulated wavelength components. The microphone detects pressure changes within the gas chamber to produce an acoustic signal, which can be used to analyze properties of the sample gas.

  • Patent number: 8069728
    Abstract: Focusing on the criterion of “Energy save” or “Quiet noise” or other suitable operating parameter and considering the existing limitation of the operation of the electro-dynamic shaker system, apparatus for optimizing the operating condition of the vibration test system is proposed. The apparatus 100 measures the field current and drive current under the state that the desired vibration is fed to the specimen 20, and calculates the necessary force the shaker 1 should supply. Field current is supposed to be varied, and the necessary drive current is calculated based on the necessary force data. Further, the blower rotation is supposed to be varied, and the total power consumption at the coils and the blower is calculated. Also the temperatures of the field coil 4 and of the drive coil 10 is estimated and checked whether within the limitation. Then the optimal operating condition for the focused criterion is selected.
