摘要： Acoustic temperature measurement at a remote location is provided. An acoustic source transmits acoustic radiation to an acoustic receiver along an acoustic path. The path passes through or near the remote location. The temperature is non-uniform along the path. A change in an integrated acoustic delay between the source and receiver along the path is measured. This acoustic delay can be either a phase velocity delay or a group velocity delay. The temperature at the remote location is determined by relating the measured change in integrated acoustic delay to the remote location temperature with a combined thermal-acoustic model. The combined model relates temperature to acoustic propagation velocity along the path. The combined model preferably includes temperatures of the source and receiver locations, and a heat source geometry at the remote location.

摘要： An acoustic energy-based, non-contact or contact testing approach provides low cost, highly accurate, and reliable information to (a) identify flaws and anomalies and (b) assess the integrity of a particular material. This approach is not hindered by surface conditions or impediments, and indeed, looks beneath the surface of the material by propagating an acoustic wave through the material using two differential transducers. A dynamic differential measurement is made of the material under a load condition and an unloaded condition that allows identification and assessment of various characteristics of the material. Multiple “windows” of information may be generated that permit (a) direct detection of flaws, defects, and anomalies using a scattering technique, (b) detection of crack closure and opening used to assess the stability of the material, (c) determination of strain on the material which relates to its performance, and (d) determination of defect dynamics linked to the defect size and stability.

摘要： A material characteristic measurement approach measures an internal state of a material by measuring the nonlinear shift in velocity induced by different acoustic energies. The technology for implementing this measurement approach is relatively simple, robust, permits portable measurements, does not require that an unloaded initial condition of the material be measured or otherwise known in order to determine a characteristic of the material, can be applied using one or more transducers, and does not require physical contact with the material. Some example material characteristics include a residual stress existing without any external mechanical force applied, applied stress, a fatigue state, age, an interference-fit fastener stress, bio-activity, a nanostructure mixture of the material, a heat treatment of the material, a cross-linking of polymers in the material, a bio-growth organization of the material, a clotting factor of blood or blood-like material, a cure of an adhesive or sealant material, or the microstructure of the material.

摘要： Acoustic weight or mass sensing technology (referred to here as Acoustic Weigh In Motion (AWIN)) provides accurate weighing of any type of moving load moving over a load bearing medium. Acoustic transducers are affixed to or embedded in the load bearing medium. One or more source acoustic transducers propagate an acoustic wave over an acoustic path through the medium between the source and receiver transducers when the medium is in an unloaded state. The wave is detected at one or more receiving acoustic transducers. A propagation time delay is determined for the unloaded state. When a moving load travels over the acoustic path in the medium, the acoustic propagation time delay for that loaded state is determined. The difference between the acoustic propagation time delays for the unloaded and loaded states is determined. That acoustic propagation time delay difference is used to determine the weight or mass of the moving load.

摘要： A method of measuring bone strength under dynamic loading is provided using an ultrasonic probe wave sensor to sense a low-frequency pump wave and an ultrasonic probe wave implemented to the bone. The bone is cyclically loaded with compressional and rarefactional pump waves, and probed with the probe wave that is timed according to the pump wave to determine the wave velocity of the probe wave. Bone strength is interpreted by measuring wave velocity changes during the pump wave cycles. Ultrasonic velocity derivatives are used to determine bone third-order (nonlinear) elastic constants that are linked to bone strength. High-resolution second-order (linear) elastic constants are provided through measurement of absolute phase velocity. A pulsed phase lock loop is locked at intervals as the probe wave phase is modulated over 360 degrees providing probe wave harmonic numbers that are correlated with the pump wave frequency to determine the probe wave velocity.

摘要： The present invention is directed towards an acoustic concealed item detector and related methods for detection using acoustics. In an illustrative embodiment, a multi-frequency ultrasonic wave generator generates in a gaseous medium at least first and second ultrasonic waves. The multi-frequency ultrasonic wave generator is arranged such that in operation, the first ultrasonic wave and the second ultrasonic wave mix in a prescribed mixing zone to produce a difference-frequency acoustic wave. A receiver sensor detects the difference-frequency acoustic wave and produces corresponding electromagnetic signals. The electromagnetic signals are processed by a system processor and signals indicative of concealed items are identified. Preferably the ultrasonic waves are focused to a small prescribed mixing zone. Parametric and multi-transducer embodiments are disclosed.
