  • Patent number: 11002641
    Abstract: A statistical method is used to separate periodic from non-periodic vibration peaks in autocorrelation spectra. Generally, an autocorrelation spectrum is not normally distributed because the amplitudes of periodic peaks are significantly large and random relative to the generally Gaussian noise. In a normally distributed signal, the statistical parameter kurtosis has a value of 3. The method sequentially removes each largest amplitude peak from the peaks in the spectrum until the kurtosis is 3 or less. The removed peaks, which are all considered to be periodic, are placed into a set. The total energy of the peaks in the set is considered to be the total periodic energy of the spectrum. As the process of building the peak set proceeds, if its total energy becomes greater than or equal to a predefined energy threshold before its kurtosis reaches 3 or less, the process stops and the periodic peak set is defined.

  • Patent number: 10641745
    Abstract: A method is disclosed to extract meta-data held in a weld scan data file and from such data determine whether the testing data is acceptable for review. A series of configuration parameters held in the scan data file are analyzed for inconsistencies and a select set of parameters are reviewed for codes and industry accepted standards compliance with recorded scan data. Additional qualitative tests may be implemented on the scan test file and unacceptable results may also provide guidance to the weld inspector as to whether continued review of the scan data file is worthwhile. Such consistency testing avoids wasteful activities reviewing a flawed weld scan data file and provides signals to operators to avoid the processing of such a file by weld scan analysis software when such processing will not result in successful assistance to a weld inspector.

  • Patent number: 10508974
    Abstract: A “store on alert” vibration data acquisition mechanism uses scalar data produced by a vibration monitoring device as a predicate to capturing and storing analytical vibration data in the vibration monitoring device. The scalar data may consist of scalar process variables generated in the vibration monitoring device that are acquired at a fixed interval, such as PeakVue and Overall Vibration. At each interval, these scalar data values are compared to machine performance threshold levels, such as ADVISE, MAINT and FAIL, to determine whether analytical vibration data is to be stored separately inside the vibration monitoring device. Since the analytical vibration data is captured based on a predicate inside the vibration monitoring device (i.e., comparison of the scalar value to the thresholds), the analytical vibration data includes more relevant diagnostic information about a specific machine performance event.

Parameters such as ellipticity, defining a shape and/or orientation of an inner surface of a wall of the hollow structure are first determined based on measured delays between transmission of ultrasound pulses from the transmitters to reception of first reflections of those ultrasound pulses. Parameters may be used that define an elliptically shaped cross-section of the inner wall surface for example. Next an ultrasound wavefront composed of joint transmissions from the transmitters along at least a sector of the array is transmitted, using relative time delays between waves transmitted by the respective ones of the transmitters to compensate for estimated differences between travel times from the transmitters to the shape defined by the parameters. Reflections of the joint transmissions are detected.

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: 9778359
    Abstract: A method for the ultrasound check of a test object involves moving a test probe along a test probe surface and sending ultrasound impulses into the test object by the test probe. Respective echo signals corresponding with the emitted ultrasound impulses are received by the test probe. An image of a predetermined test region of the test object is prepared on the basis of an overlapping and averaging of amplitude values of the received echo signals by a data processing unit. The respective position of the test probe when sending the ultrasound signals and/or when receiving the corresponding echo signals is captured by a capturing unit. The respectively captured positions of the test probe are considered when creating the image of the test region of the test object.

  • Patent number: 9759690
    Abstract: Methods, systems and computer program products for nondestructive ultrasound imaging are provided. An example method defines a plurality of subarrays, each comprising a plurality of ultrasound transducer elements. The method transmits a plurality of ultrasound beams from each of the plurality of subarrays, each ultrasound beam being transmitted at a preset beamsteering angle. Subsequent to each transmit, the method receives, at the array, a plurality of ultrasound reflections corresponding to the plurality of ultrasound beams. For each point to be imaged, the method selects one set of received element data for each of the plurality of subarrays. The selected set of element data corresponds to an ultrasound beam having a focal point closest to the point to be imaged. Finally, the method reconstructs a point to be imaged based on the selected received element data, and constructs an ultrasound image by repeating this process for each point to be imaged.

  • Patent number: 9709534
    Abstract: Ultrasonic measurement apparatus 10 includes a transmitter 14 to transmit an ultrasonic signal 16 into an item 12. A receiver 18 receives echoes 20 from the item 12. The apparatus 10 measures the frequency spectrum of the echo 20 and makes a comparison with another frequency spectrum to extract information relating to a change in the item 12. For example, the item 12 may wear during use. A comparison of the frequency spectrum, with previous frequency spectra, allows changes of dimension of the item 12 to be identified. Changes in amplitudes of the frequency spectrum allow changes in roughness to be detected.

  • Patent number: 9629557
    Abstract: After light has been output to a subject to be examined, a photoacoustic wave induced in the subject by the output light is detected. It is assumed that at least one virtual detector element is present outside of a real detector, and dummy data corresponding to the at least one virtual detector element are added to photoacoustic data in which pieces of data of the photoacoustic wave detected by the detector are arranged in accordance with the positions of detector elements. A photoacoustic image is generated by reconstructing the photoacoustic data to which the dummy data have been added by using a Fourier transform method.

  • Patent number: 9575544
    Abstract: An acoustic system, which may be ultrasonic, operates in a power efficient idle mode thereby reducing the power consumption required by high frequency sampling and processing. While in idle mode, an acoustic receiver device operates with an idle sampling rate that is lower than the full sampling rate used during full operational mode, but is capable of receiving a wake-up signal from the associated acoustic transmitter. When the wake-up signal is received, the acoustic receiver switches to full operational mode by increasing the sampling rate and enables full processing. The acoustic system may be used in, e.g., an ultrasonic pointing device, location beacons, in peer-to-peer communications between devices, as well as gesture detection.
