Abstract: A multi-function detection liner is applied to a non-cured composite material at the point of manufacturing for building a composite part. The detection liner includes a first insulative layer and a first conductive layer. The detection liner is configured to be detectable from a plurality of non-destructive inspection tests. The first insulative layer is detectable by ultrasound and radiograph within the composite part. The first conductive layer is configured to provide an eddy current signal and to enhance ultrasound attenuation of the detection liner within the composite part. Alternatively, the detection liner may include an integrated layer that combines the functions of an insulative layer and a conductive layer. The detection liner is releasably bonded to a surface of the non-cured composite material.

Abstract: A material hardness distribution display system (10) includes a probe unit (20) in which a plurality of probe elements (22) are two-dimensionally arranged. Each of the probe elements (22) has an oscillator (26) for introducing oscillation into a biological tissue and an oscillation detection sensor (28) which detects a reflected wave. The probe elements (22) are successively selected by a switch circuit (50) and connected to a hardness calculation unit (70) and a measurement depth calculation unit (82). The hardness calculation unit (70) executes a frequency component analysis for an incident wave signal to the oscillator (26) and a reflected wave signal from the oscillation detection sensor (28) to calculate the hardness of the biological tissue on the basis of the analysis results. The measurement depth calculation unit (82) calculates a measurement depth inside the biological tissue at a position where the hardness has been measured, on the basis of a temporal position of the incident wave signal and a temporal position of the reflected wave signal. They are correlated to the respective probe elements (22).

Abstract: Air bubbles may be characterized by an air bubble detector by choosing an optimum set of frequencies and then comparing a return signal from a sensor receiving those frequencies against an internal reference. The number of pulses that exceed the internal reference represents a width and may be counted. The width, as counted, may be correlated to bubble characteristics including volume.

Abstract: Increasing the effective aperture of an ultrasound imaging probe by including more than one probe head and using the elements of all of the probes to render an image can greatly improve the lateral resolution of the generated image. In order to render an image, the relative positions of all of the elements must be known precisely. A calibration fixture is described in which the probe assembly to be calibrated is placed above a test block and transmits ultrasonic pulses through the test block to an ultrasonic sensor. As the ultrasonic pulses are transmitted though some or all of the elements in the probe to be tested, the differential transit times of arrival of the waveform are measured precisely. From these measurements the relative positions of the probe elements can be computed and the probe can be aligned.

Abstract: This invention is an acoustic device protected by an acoustically transparent low water permeability encapsulant made from an acoustically clear polymer such as polyurethane. High aspect ratio clay nanoparticles are positioned in the substrate in overlapping layers with layers of the substrate interposed. The invention also provides a method for forming an acoustically transparent low permeability encapsulant about an acoustic device. The method includes treating high aspect ration clay nanoparticles to make them organophilic. The treated nanoparticles are then mixed in a polymer resin in such a way as to form an intercalated mixture. A curing agent is added to the mixture, and the mixture is allowed to set. When set the resulting intercalated mixture produces an acoustically clear, low permeability polymer coating.

Abstract: A system and method of performing acoustic thermography in which invalid data is filtered from data used to detect defects on a structure. An ultrasonic sound input signal is provided to a structure to produce a thermal image output. A sensor senses an input energy corresponding to the sound input signal and produces an input energy signal. The input energy signal is transformed to a test spectrum and is compared to a reference spectrum. The comparison of the test spectrum to the reference spectrum is used to determine whether to include the thermal image output in an analysis for detecting defects in the structure.

Abstract: Measurements of the mass and surface charge of microparticles are employed in the characterization of many types of colloidal dispersions. The suspended microchannel resonator (SMR) is capable of measuring individual particle masses with femtogram resolution. The high sensitivity of the SMR resonance frequency to changes in particle position in the SMR channel is employed to determine the electrophoretic mobility of discrete particles in an applied electric field. When an oscillating electric field is applied to the suspended microchannel, the transient resonance frequency shift corresponding to a particle transit can be analyzed to extract both the buoyant mass and electrophoretic mobility of each particle. These parameters, together with the mean particle density, can be used to compute the size, absolute mass, and surface charge of discrete particles.
