Abstract: Example systems and methods for non-destructive evaluation of depressions on a surface of an object are provided. One example system includes a measurement apparatus having a two-dimensional ultrasonic transducer array, a delay line material, a sealing member position such that the sealing member forms a cavity between the delay line material and a surface of the object, and a liquid inlet for injecting a liquid into the cavity. The example system also includes a processor configured to determine, using ultrasonic signals received from the two-dimensional ultrasonic transducer array, at least one property of a depression such as a dent on the surface of an object. The example system may also be configured to provide an output that is indicative of whether the at least one property of the depression satisfies a predetermined criterion. Another example system includes a compressible elastomeric delay line material that conforms to a surface of an object.

Abstract: A testing apparatus for an optoacoustic device includes a light pulse sensor operatively connected to a light output port of the optoacoustic device, the light pulse sensor being adapted to sense a pulse of light capable of generating an optoacoustic response in a subject and to distinguish between the light pulse and the at least one other light pulse on the basis of the predominant wavelength. The light pulse sensor outputs a trigger signal associated with the distinguished light pulse when such light pulse is sensed. A transducer signal simulator outputs a first plurality of electrical signals simulating those produced by a transducer array and reflective of an optoacoustic response in a subject to a light pulse at a first wavelength in response to a trigger signal from the light pulse sensor associated with a light pulse having a first wavelength. The simulator outputs a second plurality of electrical signals simulating those produced by a transducer array and reflective of an optoacoustic response in a subject to a light pulse at a second predominant wavelength in response to a trigger signal from the light pulse sensor associated with a light pulse having a second wavelength. Conductors carry the plurality of electrical signals output by the transducer signal simulator to the pins of a multi-pin connector.

Abstract: A self-contained, remotely operated, mobile measurement system for stand-off inspection of large target objects located at sites distant from an operations center of a distributed inspection system. In accordance with one embodiment, the system comprises a mobile platform with on-board instrumentation capable of making dimensional measurements in the local coordinate system of the target object. The system comprises multiple hardware and software components networked to a control interface that enables the operator at the operations center to teleoperate the equipment, including driving the mobile platform to a region of interest, calibrating the on-board local positioning system, acquiring measurement and image data, and communicating with on-site personnel if needed.

Abstract: A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. Elastic waves may be generated at a pump that introduces (e.g., for fill cycles) or withdraws (e.g., for drain cycles) the solution into/out of the patient line. For example, when the solution is introduced or withdrawn suddenly, elastic waves travel distally down the patient line until they encounter the occlusion, and are then reflected back (e.g., toward the pressure sensor).

Abstract: Disclosed is a phased array ultrasound total focusing method in which the ultrasound energy is transmitted as plane waves and the response signals are processed as plane waves. The processing is adaptively corrected to account for geometric variations in the probes and the part being inspected. Methods are disclosed for measuring the geometric variations of the probes and the part.

Abstract: The invention relates to a method for providing a structural condition of a structure, comprising providing an excitation wave generator; providing an excitation wave sensor; injecting an excitation burst wave into the structure using the excitation wave generator; obtaining a measured propagated excitation burst wave using the excitation wave sensor; correlating the measured propagated excitation burst wave with one of a plurality of theoretical dispersed versions of the excitation burst wave; and providing an indication of the structural condition of the structure corresponding to the correlated measured propagated excitation burst wave. The method may offer a better localization of the reflection points and thus of the potential defects present in a structure under inspection, when compared with a group velocity-based or time-of-flight (ToF) approach. The method may be particularly useful for structural health monitoring (SHM) and Non-Destructive Testing (NDT). The method may also enable determination of the mechanical properties of the structure.
