  • 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.

    Abstract: An amount of wear of a railroad vehicle wheel flange online while traveling in a curved section is directly measured. A laser rangefinder 3 is installed on an outer track side in a rounded curve section of a railroad track. When a railroad vehicle travels through the rounded curve section, the laser rangefinder 3 measures a distance to a front rim surface of a wheel on an outer track side of a wheelset in a forward direction of travel of a bogie forming a vehicle. The amount of wheel flange wear is obtained by comparing this measured distance with a previous measurement of the measured distance. It is then possible to control the amount of wheel flange wear when traveling in a curved section, thus making it possible to quickly find wheels having flange wear that has exceeded a control range and ensure safety during travel of the railroad vehicle.

  • Patent number: 10267772
    Abstract: Technologies are generally described for measuring hair moisture using a hair moisture measuring device including a vibrator, a sound wave detector, a heater, and/or a processor. The vibrator may generate and propagate first sound waves through a strand of hair, which may be detected by the sound wave detector. The processor may then measure a first time-delay between the first sound waves and the first driving signals. After heating the hair by the heater, the vibrator may generate and propagate second sound waves through the strand of hair, which may be detected by the sound wave detector. The processor may measure a second time-delay between the second sound waves and the second driving signals, and also measure an amount of the moisture by calculating a time-delay difference between the first time-delay and the second time-delay.

  • Patent number: 10241201
    Abstract: In a method and system for inspecting the condition of a structure, the structure is scanned with a three-dimensional (3D) scanner. The 3D scanner includes a sensing system having one of a radar sensing device or an ultrasonic detection device. The sensing system detects 3D information about a subsurface of the structure, and the 3D scanner generates 3D data points based on the information detected by one or more of the radar sensing device and the ultrasonic detection device. A 3D model is constructed from the 3D data and is then analyzed to determine the condition of the subsurface of the structure.

  • Patent number: 10239750
    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: 10139373
    Abstract: A method and a device for the near-surface, non-destructive inspection by means of ultrasound of a rotationally symmetric workpiece having a diameter that changes from section to section are provided. The method and device are based on the insonification of an ultrasonic test pulse into the workpiece at a defined insonification angle and the subsequent recording of an ultrasonic echo signal from the workpiece. Echo signals that trace back to a near-surface region ROI of the workpiece are identified and evaluated. Then, a graphic representation of the surface of the workpiece is generated.

  • Patent number: 10126155
    Abstract: A method and system for measuring a fluid parameter of a fluid within a fluid containment vessel includes mounting a first multi-sensor assembly to a fluid containment vessel, the first multi-sensor assembly having two or more multi-sensor pairs located at consecutive heights of the fluid containment vessel, each of the two or more multi-sensor pairs having a first multi-sensor and an opposite second multi-sensor, each of the two or more multi-sensor pairs being in communication with a single transmitter assembly. A signal is sent from the first multi-sensor towards the second multi-sensor of the two or more multi-sensor pairs. A transit time for the signal to pass between the first multi-sensor and the second multi-sensor is measured. The transit time of adjacent multi-sensor pairs is compared to identify a fluid boundary within the fluid containment vessel.

  • Patent number: 10041967
    Abstract: A method of determining a velocity of air flowing in an air flow direction through an opening. The method includes locating first and second transducer assemblies in the opening, to position the first and second transducer assemblies spaced apart by a predetermined distance along a substantially straight line of sight defining a non-zero angle in a horizontal plane between the line of sight and the air flow direction. A controller is operatively connected with the first and second transducer assemblies respectively, via a four-wire interface in which two of the wires are for power transmission and two of the wires are for transmitting signals. The transducer assemblies are time-synchronized. First and second electronic signal pulses are transmitted between the first and second transducer assemblies. Based on the transit times, the non-zero angle, and the predetermined distance, the velocity of the air flowing in the air flow direction is determined.
