  • Patent number: 10546372
    Abstract: Embodiments of the present invention provide methods, machines, and a computer medium or media having computer programs to determine presence anomalies in circumferential welds of one or more pipelines transporting fluids associated with energy therethrough. Wave form analysis or pattern recognition in pipeline data such as magnetic flux leakage data is employed. A screening process, for example, does not affect or change how survey data is recorded such as in survey tools; only how it is analyzed after the survey data is completed. Embodiments of the machines, methods, and computer medium having computer programs can be used to screen for anomalies potentially threatening the structural integrity of the one or more pipelines so that site excavation can occur for confirmation and validation of the output results.

  • Patent number: 10386337
    Abstract: Resonant Ultrasound Spectroscopy (RUS) is applied to diamonds (both cut/polished gemstones and rough diamonds) to yield a digital fingerprint from which the stone may be authenticated and sorted according to the structural quality. Diamonds are mined as rough stones from which they undergo examination to determine their value as being gem, or of two different industrial qualities. Fewer than 25% of mined diamonds are worthy of cutting and polishing to yield gems for jewelry. About 40% of the remaining population still have value as industrial diamonds for machine tools, and the rest is ground into dust to provide coatings for grinding applications. Rough stones exist in two conditions being coated and uncoated. The coated stones have a layer of polycrystalline diamond, different from the predominant crystal structure, rendering them opaque. This interferes with optical inspection, as any cracks, or inclusions can't be seen.

  • Patent number: 10234702
    Abstract: In an optical device, a ring-resonator modulator, having an adjustable resonance (center) wavelength, receives an optical signal that includes a carrier wavelength from an input-output optical waveguide. Then, a monitoring mechanism monitors a performance metric (such as an average power or a signal swing) of a monitor optical signal from the ring-resonator modulator. Moreover, control logic in the optical device adjusts the resonance wavelength based on the monitored performance metric so that the resonance wavelength is locked to the carrier wavelength. In particular, the control logic may apply a change to an adjustment signal that is provided to the ring-resonator modulator. If the change increases the performance metric, the control logic may continue to modify the resonance wavelength. Otherwise, the control logic may modify the resonance wavelength by applying one or more changes, having an opposite sign to the change, to the adjustment signal.

  • Patent number: 10053831
    Abstract: The invention relates to a method for determining the radius of a pile in the ground that can be produced by means of a jet-grouting process, comprising the steps of: introducing at least one level-measuring stick into the ground; sinking a jet-grouting tool (3) down to a defined distance from the level-measuring stick (4), the distance being less than a maximum range R of the grouting jet; pulling the jet-grouting tool (3) while performing a rotating or swivelling motion with the grouting jet activated, thereby producing vibrations as the grouting jet passes the level-measuring stick (4); and recording a signal representative of the vibrations at the at least one level-measuring stick (4) by means of a sensor (5) that is fastened to the level-measuring stick (4). The invention also relates to a corresponding arrangement (2) for determining the radius of a pile in the ground that can be produced by means of a jet-grouting process.

  • Patent number: 10036730
    Abstract: A sensor array comprises resonant sensors and porous receptor materials arranged on the resonant sensors to absorb or adsorb one or more analytes. The average pore size of the porous receptor materials on the sensors increases systematically from one sensor to the next in the array. At least one detector is arranged to detect responses of the resonant sensors when the array is exposed to a sample potentially containing one or more of the analytes. In some embodiments, a processor is programmed to determine from the sensor responses the presence, amount or relative concentration of target molecules in the sample.

  • Patent number: 10028250
    Abstract: A method in a wireless communication terminal includes receiving configuration signaling for transmitting on a first set of radio resources wherein transmitting only on the first set of radio resources leads to a time-domain periodic repetitive pattern of transmissions from the terminal in a transmission interval that causes interference to a companion device communicably coupled to the wireless communication terminal. The terminals selects a second set of radio resources for transmitting on in the transmission interval such that transmissions on a combination of the second set of radio resources and the first set of radio resources does not lead to a periodic repetitive pattern of transmissions from the terminal in the transmission interval.

  • Patent number: 9964524
    Abstract: A method and an apparatus for bolt inspection are presented. The bolt has a cylindrical threaded surface delimited by a pair of end faces that are opposite to each other. An ultrasonic transducer device contacts one of the pair of end faces for performing a scan operation. A guide structure is engaged with the bolt that guides a motion of the ultrasonic transducer device such that only a portion of a transducer contact surface contacts the one of the pair of end faces during the scan operation. The guide structure delimits a radial extent of the motion of the ultrasonic transducer device during the scan operation.

  • Patent number: 9933394
    Abstract: A method is disclosed for testing for delamination of a first composite component from a second composite component a composite material. The method comprises coupling a broad-band actuator to the composite material and connecting sweeping frequencies to the broad-band actuator for vibrating the composite material. An acoustic sensor is coupled to the composite material for measuring a resonant frequency curve of the vibrating composite material. The measured resonant frequency curve of the vibrating composite material is compared with a reference resonant frequency curve. A delaminated composite material produces a change in the measured resonant frequency curve relative to the reference resonant frequency curve. The method is suitable for detecting delamination in fuel cells as well as ceramic body armor.
