摘要： Disclosed is a system and method of determining the test surface profile and compensating the gain amplitude when using time reversal focal laws in ultrasound non-destructive testing. Computer simulations are used to compute the diffraction field at time of incidence of the transmitted parallel wave front on the test surface. Knowledge of the surface profile and the diffraction field allows determination of coverage at the test surface and improved accuracy of flaw sizing.

摘要： 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.

摘要： The present invention is related to a device and a method using said device for the measurement and classification of bubble sizes in a liquid medium. This invention comprises two electric emitter and receiver transducers located at an angle lower than 180 degrees one with respect to the other, and ultrasonic signal emitter and receiver circuits operatively connected to the electric emitter and receiver transducer respectively. The classification of the bubble sizes is based on two-dimensional time domain patterns that represent the trace of the bubbles when they cross a generated ultrasonic field. This invention is of great utility to track processes involving the generation of bubbles in liquid media such as the froth flotation in mining.

摘要： A phased array ultrasonic inspection system configured for weld inspection includes a data analysis process with automated and optimized gating to take into account the actual distance between a phased array probe and a weld line. The system embodies a weld tracking module and a dynamic gating module. The tracking module produces dynamically corrected overlays of the weld line based on the echo signals, the dynamically corrected overlays having a series of offsets from the corresponding initial overlays. The dynamic gating module purposefully positions a plurality of data analysis gates to filter out noise signals caused by sources unrelated to the weld, and to provide dynamic target gating adjusted by at least part of the offset.

摘要： Operational configuration and temperature compensation methods are provided for bulk acoustic wave (BAW) resonator devices suitable for operating with liquids. Temperature compensation methods dispense with a need for temperature sensing, instead utilizing a relationship between (i) change in frequency of a BAW resonator at a phase with adequate sensitivity and (ii) change in frequency of a phase that is correlated to temperature. Operational configuration methods include determination of an initial phase response of a BAW resonator in which temperature coefficient of frequency is zero, followed by comparison of sensitivity to a level of detection threshold for a phenomenon of interest.

摘要： Disclosed is a calibration method and system for non-destructive testing and inspection (NDT/NDI). The method and system involve establishment of a reference database by conducting FMC acquisition on a first calibration block having standardly known indications with a first series of depths and under a laboratory standard calibration condition. Then phased-array operation is conducted on a second calibration block, which is substantially the same as the first block, having indications with a series of corresponding user measured depths and under a second calibration condition as close to the laboratory condition as possible. The calibration is then made with the gain compensation calculated based on the response signals from the indications of the second block, the first series of gain data from the reference database, and the user measured depths for the corresponding indications under the second calibration condition.

摘要： A method for ultrasonically inspecting components with wavy or uneven surfaces. A multi-element array ultrasonic transducer is operated with a substantial fluid layer, such as water, between the array transducer and the component surface. This fluid layer may be maintained by immersing the component in liquid or by using a captive couplant column between the probe and the component surface. The component is scanned, measuring the two dimensional surface profile using either a mechanical stylus, laser, or ultrasonic technique. Once an accurate surface profile of the component's surface has been obtained, data processing parameters are calculated for processing the ultrasonic signals reflected from the interior of the component that eliminate beam distortion effects and reflector mis-location that would otherwise occur due to the uneven surfaces.
