  • Patent number: 11033895
    Abstract: Focused acoustic radiation, referred to as tonebursts, are applied to a volume of liquid to generate a set of droplets. The droplets generated are substantially smaller in scale than the focal spot size of the acoustic beam (e.g., the frequency at which the acoustic transducer operates). Further, the droplets have trajectories that are substantially in the direction of the acoustic beam propagation direction. In one embodiment, a first toneburst is applied to temporarily raise a protuberance on a free surface of the fluid. After the protuberance has reached a certain state, a second toneburst is applied to the protuberance to break it into very small droplets. In one embodiment, the state of the protuberance at which the second toneburst is supplied is the time period shortly after the protuberance reaches its maximum height but before the protuberance recedes back into the volume of fluid.

  • Patent number: 10927667
    Abstract: Externally generated noise can be coupled into a fluid carrying structure such as a pipe, well, or borehole so as to artificially acoustically “illuminate” the pipe, well, or borehole, and allow fluid flow in the structure or structural integrity to be determined. In the disclosed system, externally generated noise is coupled into the structure being monitored at the same time as data logging required to undertake the monitoring is performed. This has three effects. First, the externally generated sound is coupled into the structure so as to “illuminate” acoustically the structure to allow data to be collected from which fluid flow may be determined, and secondly the amount of data that need be collected is reduced, as there is no need to log data when the structure is not being illuminated. Thirdly, there are signal processing advantages in having the data logging being undertaken only when the acoustic illumination occurs.

  • Patent number: 10761228
    Abstract: New methods for calculating acquisition illumination are computationally less expensive in comparison with conventional methods. In one such new method, source wavefield propagations are calculated and assigned to corresponding zero-offset receivers. Further, the number of non-zero-offset receivers within the coverage of the shot at the source location is decimated. Such a method is most advantages in reverse time migration, in which all source wavefield propagations are already calculated. The receiver-side illumination for each shot can be obtained by summing up all the source-side illumination with the source located within receiver coverage. All the source-side illumination and receiver-side illumination can be summed up to get the acquisition illumination for the survey. The acquisition illumination can be used to value the acquisition system and to compensate the migration images.

  • Patent number: 10656266
    Abstract: Described in detail herein are methods and systems for estimating storage capacity of a storage unit disposed in a facility based on echoes detected by microphones. The microphones can detect sounds generated in the warehouse and reflected off the storage unit structures. The microphones detect the intensity of the sounds. The microphones can encode the sounds and the intensity of the sounds in time-varying electrical signals and transmit the time-varying electrical signals to a computing system. The computing system can decode the sounds and the intensity of the sounds from the time-varying electrical signals and estimate storage capacity of a storage unit from which the sounds reflected off of based on the intensity of the sounds.

  • Patent number: 10627370
    Abstract: Methods of testing the material of a metal object made by additive manufacturing. An electromagnetic acoustic transducer (EMAT) is used to transmit long duration acoustic signals into the object, and to receive response signals representing resonance of acoustic waves within the material. At least one resonance peak is identified and used to determine attenuation and/or wave velocity. These values can then be used to determine material properties, such as porosity, Shear Modulus, Young's Modulus, or Poisson's Ratio.

  • Patent number: 10626009
    Abstract: In a method of inferring ambient atmospheric temperature, an acoustic signal is emitted from a speaker. A first sample of the acoustic signal is captured with a first microphone spaced a first distance from the speaker. A second sample of the acoustic signal is captured with a second microphone spaced a second distance from the speaker. The second distance is greater than the first distance, and a difference between the first distance and the second distance is a known third distance. A time delay in the acoustic signal is determined between the first sample and the second sample. An ambient temperature of the atmosphere through which the acoustic signal traveled is inferred based on a relationship between the time delay and temperature for the acoustic signal over the third distance.

  • Patent number: 10591330
    Abstract: Flow rate measurement is performed with a propagation time by using a pair of ultrasonic wave oscillators which is provided in flow path through which a fluid to be measured flows, and is disposed so as to transmit and receive an ultrasonic wave signal by causing the ultrasonic wave signal to be reflected on an inner wall of flow path at least once. In addition, adjustment of an amplification rate is periodically performed by amplifier, which amplifies the ultrasonic wave signal received by each of the ultrasonic wave oscillators to a predetermined amplitude, and a difference between a previous amplification rate and a current amplification rate is a predetermined value or more, and the instantaneous flow rate calculated by flow rate calculation unit is a predetermined flow rate or less, the reference voltage is adjusted by reference voltage setting unit. With the configuration, the propagation time can be stably measured and deterioration of the maximum amplitude is prevented.

  • Patent number: 10551231
    Abstract: An ultrasonic flow meter is disclosed comprising adjustable rotating blocks and a piezoelectric wafer mounted in connection with each rotating block. The piezoelectric wafers or chips are used for transmitting and/or receiving upstream and downstream ultrasonic waves. The rotating blocks adjust the incident angle of the piezoelectric wafers to account for installation in connection with different pipe sizes. By adjusting angle in a linked and continuous manner, no translational sensor movement is required for an optimal ultrasonic wave reflection for the downstream transducer to receive a signal from the upstream transducer and the upstream transducer to receive a signal from the downstream transducer. As such, the devices and methods described enable measurement of liquid flowing in pipes across a range of different diameter pipes so as to greatly increase the convenience and the extent of application or technology adoption.

  • Patent number: 10527510
    Abstract: In the present disclosure, embodiments including a system, probe and method are disclosed for accurately measuring the strain or extension of a fastener that occurs as the nut on the fastener is tightened and the fastener is put under load. The measurement technique is based on measurement of the time for an ultrasonic wave generated on one end of the fastener to travel a round trip through the fastener. As the fastener is tightened, the applied stress causes an associated increase in length. This length can be determined from a measurement of the increase in transit time. In various embodiments, the disclosed device and method uses laser ultrasonic testing (LUT), in which a pulsed laser generates the ultrasonic wave and a type of laser vibrometer detects the wave when it returns to the position of generation following a combination of longitudinal and shear wave reflections.
