  • Patent number: 9970905
    Abstract: A defect monitoring system has ultrasound transmitters and receivers on a wall of a structure under test such as a pipeline. The receivers are arranged in an array of locations that substantially encloses an area under test on a wall of a structure under test. The array may comprise two circumferential rings along a pipeline at different axial positions. The array of ultrasound receivers is used to measure signals that result ultrasound that leave the area through the wall for other parts of the wall. From the measured signals backward propagated signals are computed for a location within the enclosed area, compensated for a modelled effect of propagation from the location within the area to the locations of the receivers at the perimeter. The backward propagated signals for the location in the enclosed area are summed over the locations of the receivers to obtain an approximate integral over the perimeter of the area.

    Abstract: A device and a method for detecting at least one defect in a test object (2). At least one test head (1) radiates an ultrasonic signal at different measuring points (MP) into the test object (2) with each point at an insonation or radiation angle (?) in order to ascertain multiple measurement data sets (MDS). The angle is constant for each data set (MDS). An analyzing unit (4) carries out an SAFT (Synthetic Aperture Focusing Technique) analysis for each ascertained measurement data set (MDS) using a common reconstruction grid (RG) inside the test object (2) in order to calculate an SAFT analysis result for each measurement data set (MDS). The analyzing unit (4) superimposes the calculated SAFT analysis results in order to calculate an orientation-independent defect display value (SRP) for each reconstruction point (RP) of the common reconstruction grid (RG).

  • Publication number: 20150006091
    Abstract: Embodiments of systems and methods that can filter acoustic energy from sources remote from the valve. These embodiments utilize signals from sensors that manifest acoustic energy from various locations on and/or about the valves. In one embodiment, the system includes sensors at locations proximate the valve and locations spaced apart from the valve. The system can further process the signals from these locations and, in one example, combines samples of data to form an energy signature of the valve that is effectively free of noise that emanates from upstream and/or downstream of the valve.

  • Patent number: 8924164
    Abstract: An apparatus and a method for ultrasonic testing obtains high-resolution and high-S/N ratio testing results by driving a number of piezoelectric elements using fewer pulsers and receivers in comparison with the number of elements composing an array transducer. A sensor information setter sets a plurality of piezoelectric element groups used for transmission and a plurality of piezoelectric element groups used for reception among the plurality of piezoelectric elements composing an ultrasonic array transducer. A computer transmits an ultrasonic wave from the element cluster set for transmission, and stores an ultrasonic wave received by the element cluster set for reception. The procedure is repeated including different element cluster sets for transmission and reception to obtain first receive signals. The first receive signals are summed to obtain a second receive signal; and the second receive signal is displayed with reference to the sensor center position on a display unit.

  • Patent number: 8884793
    Abstract: A method for reducing ultrasound data from an ultrasound signal includes rectifying the ultrasound signal and generating an envelope curve about maximum values of the rectified ultrasound signal. Each ultrasound pulse is represented as a curve portion with a single maximum value. A first negative envelope curve signal, which is reduced by a first factor f, and a delayed envelope curve signal, which is not modified but is delayed by a time period td, are produced. The first negative envelope curve signal and the delayed envelope curve signal are added to form a first sum signal with a first zero crossing, wherein the first zero crossing represents a first time value. An amplitude is associated with the first time value, the amplitude corresponding to a signal height consistent with a maximum peak height from the envelope curve within a time interval about the first time value.
