  • Publication number: 20240118245
    Abstract: In some implementations, a method includes receiving data characterizing a plurality of acoustic signals detected at a plurality of segments of an industrial system. A first data subset of the received data is associated with a first acoustic signal detected at a first segment of the plurality of segments and a second data subset of the received data is associated with a second acoustic signal detected at a second segment of the plurality of segments. The method also includes a first characteristic color to the first data subset based on a first time of propagation and an amplitude of the first acoustic signal, and assigning a second characteristic color to the second data subset based on a second time of propagation and amplitude of the second acoustic signal.

  • Publication number: 20240111368
    Abstract: An apparatus for performing non-destructive testing is provided. The apparatus includes a housing having a front face for displaying a user interface and a rear face. A plurality of first buttons is disposed on the rear face of the housing adjacent to a side face, and receives a first set of user inputs from a user. One or more second buttons are disposed on the housing and receive a second set of user inputs from the user. The first set of user inputs and the second set of user inputs are received via a forefinger and a thumb, respectively, of the user. The plurality of first buttons and the one or more second buttons are together configured to select a precise value of an operating parameter of the apparatus. Related methods of use are also described.

  • Patent number: 11579120
    Abstract: A method includes receiving data characterizing a first acoustic signal reflected by a first defect in a target object, and a first depth of the first defect relative to a surface of the target object. The first acoustic signal is detected by a detector located at a first location on the surface of the target object. The method also includes assigning a defect color to the received data based on an amplitude value associated with the first acoustic signal and one or more of a first predetermined threshold value and a second predetermined threshold value associated with the first depth. The method further includes rendering, in a graphical user interface display space, a first visual representation of the first acoustic signal in a graph including a first axis indicative of target object defect depth and a second axis indicative of amplitudes of acoustic signals detected by the detector. The first visual representation of the first acoustic signal includes the assigned defect color.
