Abstract: The method of validating a calibration of a phased-array inspection instrument uses a calibration block having two reflectors located below an inspection surface at two different depths. The method comprises: obtaining angle reference data associating expected angles with corrected angles, each corrected angle being usable to propagate a phased-array beam into the calibration block at a true angle relative to the inspection surface that corresponds to the corresponding expected angle; propagating, from the inspection surface and targeting each one of the two reflectors, phased-array beams into the calibration block at a true angle using the angle reference data, and measuring echo signals associated with the propagated phased-array beams; determining time-of-flight values corresponding to the reflection of the phased-array beams on the two reflectors using the echo signals; and validating the calibration of the phased-array inspection instrument using the time-of-flight values, the two different depths and the true angle.

Abstract: A computer with a proper program generates a phased array sequence of signals. In a pulser with delays, the signals are fed through a multiplexor into multiple water wedges that are attached to a lift-type check valve being tested. For a sequential operation of the lift-type check valves from the open to the closed position, ultrasonic signals are transmitted through the fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the lift-type check valve to determine if the lift-type check valve is operating properly. By comparing the signals received with a known standard for that lift-type check valve, proper operation, or lack thereof, of the lift-type check valve under test can be determined.

Abstract: The invention relates to a method for testing of a train wheel by ultrasound. The method is based on a pulsed ultrasonic field in the train wheel to be tested by an array of individually controllable ultrasonic transmitting transducers acoustically coupled to the train wheel each controlled with a specific analog transient excitation signal. Each analog transient excitation signal generated based on an ultrasonic transmitting transducer-specific stored digital transient excitation function. The resulting echo signals from the train wheel to be tested are recorded by an array of individually controllable ultrasonic receiving transducers. Each ultrasonic receiving transducer can provide an analog, time-resolved echo signal. The received echo signals can be digitized in a transducer-specific way and stored in a set. A plurality of different reception processing rules can then be applied to the latter. Furthermore, the invention relates to a device for carrying out the method.

Abstract: Inspection devices nondestructively sense component shape and integrity such as through ultrasonic sensors. Inspection devices include a positional determinator to give orientation of devices relative to the tested object. True distances and relative boundaries of the object are determined with testing and orientation data regardless of rigid or known inspection device position. Inspection data can be corrected for refraction knowing distances and object boundaries. Inspection devices can include additional inspection components like cameras and lighting to match visual inspection with nondestructive testing data spatially and temporally. Inspection devices can be used with self- or manual-propulsion in a working environment with the inspection object. Inspection devices use an operator or computer processor, local or remotely-connected power sources, and communications structures to power and operate the devices.

Abstract: An acoustic matching layer is formed on individual ultrasonic transducer elements on a base. Electric conductors are arranged between adjacent ultrasonic transducer elements, the electric conductors being connected to electrodes of the ultrasonic transducer elements. Protective films overlap the electric conductors. The protective films have smaller moisture permeability than the acoustic matching layer. Wall portions are arranged on the protective films, the wall portions separating portions of the acoustic matching layer that are respectively located on adjacent ultrasonic transducer elements from each other at least in a part of a height range with respect to a height direction from the base, and having an acoustic impedance that is different from the acoustic impedance of the acoustic matching layer.

Abstract: A plurality of micro-electro-mechanical system (MEMS) transducers in a phased array are coupled to a flexible substrate using carbon nanotubes (CNTs) for conformal ultrasound scanning. Each transducer comprises a cantilever, magnetic material deposited on the cantilever, and a solenoid positioned relative to the magnetic material. The carbon nanotubes are grown on the cantilever and mechanically couple the transducer to one side of the flexible substrate. The other side of the flexible substrate is applied to a surface of a part under inspection, and the transducers are electrically connected to a processer to cause movement of the cantilevers when the solenoids are energized by the processor. The movement of the cantilevers results in movement of the carbon nanotubes, which imparts a force to the flexible substrate that results in ultrasound waves, which permeate the part. Returns from the ultrasound waves are interpreted by the processor to generate images of the part.

Abstract: A single-element ultrasonic sensor includes a single transducer element and transmits an ultrasonic wave on the basis of a pulse wave. An ultrasonic array sensor includes a plurality of transducer elements and receives an ultrasonic reflected wave. A pulsar supplies the pulse wave to the single element ultrasonic sensor. A receiver receives electric signals from the transducer elements included in the ultrasonic array sensor. An amplification and conversion unit amplifies the electric signals received from the transducer elements included in the ultrasonic array sensor, converts the electric signals into digital signals, and arranges the digital signals in a serial order so as to generate a serial digital signal. An image generator generates an image on the basis of the serial digital signal.
