There is provided detection instrumentation for the detection of transverse rail defects in rail head hitherto considered untestable on account of acoustic signal attenuation problems of horizontal lamination defects. The detection instrumentation comprises a pulse-echo acoustic transducer having a wear face for contacting a fillet of the rail and being aimed towards a head of the rail such that the transmitter transmits acoustic signals into the head and the receiver receives acoustic signals reflected at differing depths within the head. A signal receiver operably coupled to the receiver times the acoustic signals according to a timeseries railhead depth position scale. Analysis of the depth positions of the reflected acoustic signals according to relative positioning of the instrumentation along the rail may identify the transverse rail defects

According to an embodiment, a signal processing apparatus includes a receiver, a time information generator, a processor, and a communicator. The receiver receives a voltage signal from a sensor that detects an elastic wave generated from a structure. The time information generator generates time information having a bit length based on a measurement continuing time period of the structure, a propagation velocity of the elastic wave, and a position identification accuracy of a generation source of the elastic wave. The processor generates detection information in which feature amount information that indicates a feature of the voltage signal and the time information that indicates a reception time of the voltage signal are in association with each other. The communicator transmits the detection information to a server.

The present disclosure provides systems, machine-readable media, and methods for detecting and assessing damage to a vehicle. One or more embodiments include determining an amount of damage to a component based on reflected acoustic energy by comparing baseline data before damage is sustained to response data collected after damage is sustained.

A system and method directed to inspecting a high density polyethylene pipe. The system includes a pipe inspection tool that is positioned about a fused polyethylene pipe joint. The inspection tool may include search units, a pipe carriage, a pulser and a phased array testing instrument programmed to adjust an amplitude response signal from the search units based on a vertically established time corrected gain curve. The inspection tool is rotated around the high density polyethylene pipe joint while propagating acoustical waves at various patterns and angles through the polyethylene pipe joint. Prior to the joint inspection, the inspection tool is calibrated using a calibration tool which includes a block having an array of equal sized bores positioned along different axis' through the block's depth. The block is constructed of the same material type and grade as the pipes that were fused together to form the polyethylene pipe joint.

Vibration data indicative of the health of a machine is collected using a vibration sensor connected to a vibration data collector. After the vibration sensor has been attached to a measurement point on the machine, vibration data is collected that includes a bin of data having a begin time and an end time, and the vibration data is stored in memory of the vibration data collector. First and second average amplitudes of the bin of vibration data collected during first and second time windows in the measurement time period are determined. The slope of the vibration data is calculated based on the ratio of the amplitude difference between the first and second average amplitudes and the time difference between the first and second time windows. The vibration data is either retained in the memory or discarded based on the comparison of the slope to a threshold level.

Systems, methods, and a computer readable medium are provided for determining a minimum geometric dimension of an indication of an object being inspected using ultrasonic data.

The computing device can apply a geometric template figure to the determined contour such that the geometric template figure is enclosed by the contour. At least one minimum geometric dimension of the indication can be determined based on determining a maximum dimension of the geometric template figure enclosed by the contour. The computing device can provide the at least one minimum geometric dimension of the indication.
