  • Patent number: 10996203
    Abstract: Acoustic transducers generate and receive acoustic signals at multiple locations along a surface of rigid structure, wherein longitudinal spacing between transducer locations define measurement zones. Acoustic signals with chosen amplitude-time-frequency characteristics excite multiple vibration modes in the structure within each zone. Small mechanical changes in inspection zones lead to scattering and attenuation of broadband acoustic signals, which are detectable as changes in received signal characteristics as part of a through-transmission technique. Additional use of short, narrowband pulse acoustic signals as part of a pulse-echo technique allows determination of the relative location of the mechanical change within each zone based on the differential delay profiles. For accurate acoustic modeling and simulation, the mesh size, time step, time delay, and time-window size are optimized.

  • Patent number: 10788460
    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.

After the vibration sensor has been attached to a measurement point on the machine, vibration data is collected over a measurement time period having a begin time and an end time, and the vibration data is stored in memory of the portable vibration data collector. First and second average amplitudes of the vibration data collected during first and second time windows in the measurement time period are determined. The slope of the vibration data is calculated based on the ratio of the amplitude difference between the first and second average amplitudes and the time difference between the first and second time windows. The vibration data is either retained in the memory or discarded based on the comparison of the slope to a threshold level.

  • Patent number: 10295435
    Abstract: In one example embodiment, an analysis software package implements an improved damage detection technique to identify damaged elements of a structure. The software package accesses a model and receives measured responses resulting from physical testing of the structure under initial conditions and under damaged conditions. The analysis software package may search for a set of damaged elements, wherein the searching is based on an error function that evaluates goodness-of-fit between the model and the structure under damaged conditions based on a discrepancy between a modeled response difference and a measured response difference, wherein the modeled response difference is a difference between modeled responses determined from the model configured to model initial conditions and with selected damaged elements, and the measured response difference is a difference in measured responses determined from physical testing of the structure under the initial conditions and under the damaged conditions.

  • Patent number: 10278671
    Abstract: Shear waves are detected with ultrasound. The detection of the shear wave is constrained using prior measurements in a more controlled environment (e.g., less noise). For example, shear waves measured in a phantom are used to constrain the detection of shear waves in a patient to avoid false positive detections.

Each loft angle difference between two golf clubs that are adjacent in a loft angle order is the same. Each club length difference between two golf clubs that are adjacent in the loft angle order is 0.125 inches (3.175 mm) (inclusive) to 0.375 inches (9.525 mm) (inclusive). A loft angle of a golf club having a minimum frequency is smaller than a loft angle of a golf club having a maximum frequency. A difference between the minimum frequency and the maximum frequency is not less than 40 cpm.

  • Patent number: 10241006
    Abstract: A method for monitoring the operation of a gas turbine is provided, in which component vibrations are detected during the operation of the gas turbine by an acceleration sensor arranged on the component, a plurality of signal sections being determined by a plurality of frequency bands fb from the signal forwarded and processed by the acceleration sensor. To avoid an unnecessary shutdown of the gas turbine to perform an inspection which subsequently proves unnecessary, thereby increasing the availability of the gas turbine, a total vibration period is determined by adding together the vibration periods of signal sections during which the amplitudes of the signal sections concerned are greater than a frequency band-specific threshold.

  • Patent number: 10240971
    Abstract: A vibration visualizer comprising an optical member including a fixed section to be fixed to a measurement object; and a movable section movably supported by the fixed section such that a first positional relationship between the fixed section and the movable section is changed by application of an acceleration to the fixed section in a predetermined direction. The optical member changes a reflection intensity of light or electromagnetic wave reflected in a retroreflection direction according to a change of the first positional relationship. The first positional relationship in a stationary state where the acceleration is not applied to the fixed section and the first positional relationship is maintained constant, is different from the first positional relationship most suitable for retroreflection.

  • 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.
