    Abstract: A system, method, and computer program product for utilizing an ultrasonic sensor compensating for the physical conditions of an internal battery compartment (e.g., temperature and/or humidity), to detect a hazardous battery condition, is provided. An example system includes a battery case defining an internal battery compartment and one or more battery cells contained in the internal battery compartment. The example system further includes an acoustic transmitter disposed within the internal battery compartment and configured to transmit an acoustic signal. In addition, the example system includes an acoustic receiver also disposed within the internal battery compartment and positioned to receive the transmitted acoustic signal. The example system monitors the time of flight of the acoustic signal and detects the hazardous battery condition of the one or more battery cells based on a change in the time of flight of the acoustic signal.

    Abstract: Acoustic inspection productivity can be enhanced using techniques to perform compression of acquired acoustic data, such as data corresponding to elementary A-scan or other time-series representations of received acoustic echo data. In various approaches described herein, time-series data can be decimated for efficient storage or transmission. A representation of the time-series data can be reconstructed, such as by using a Fourier transform-based up-sampling technique or a convolutional interpolation filter, as illustrative examples. The techniques described herein can be used for a variety of different acoustic measurement techniques that involve acquisition of time-series data (e.g., A-Scan data). Such techniques include Full Matrix Capture (FMC) applications, plane wave imaging (PWI), or PAUT, as illustrative examples.

    Abstract: A predicting system and method for the uniaxial compressive strength of rock include a point loading strength test module, a longitudinal wave velocity test module, a rock rebound value test module and a strength prediction module, wherein the longitudinal wave velocity test module performs longitudinal wave velocity tests on the rock, and transfers the longitudinal wave velocity of the rock to the strength prediction module; the rock rebound test module performs rebound test on the rock, and transfers the rebound value of the rock to the strength prediction module; the point loading strength test module performs image acquisition on a fracture surface of the rock after being loaded and fractured by the point loading test, and calculates the area of the fracture surface; and the strength prediction module outputs a uniaxial compressive strength prediction result of the rock according to the received information and a preset prediction model.

    Abstract: An ultrasonic inspection apparatus includes a control device 12 that outputs a pulse signal for making an ultrasonic probe 11A transmit an ultrasonic wave to the ultrasonic probe 11A and that is supplied with a waveform signal obtained by converting the received ultrasonic wave from an ultrasonic probe 11B, and that computes a thickness reduction depth of a pipe 1 between the ultrasonic probe 11A and the ultrasonic probe 11B. The control device 12 computes the thickness reduction depth of the pipe 1 by selectively using a reception time of the ultrasonic wave transmitted from the ultrasonic probe 11A, reflected once by an inner surface 3 of the pipe 1, and received by the ultrasonic probe 11B, and a reception time of the ultrasonic wave transmitted from the ultrasonic probe 11A, reflected twice by the inner surface 3 of the pipe 1, and received by the ultrasonic probe 11B.
