    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: A method for evaluating changes in the intensity of polychromatic radiation that is transmitted by a source having a known frequency spectrum (e.g. an X-band spectrum), and received by a sensor after having passed through a certain thickness of a body or sample consisting of one or more phases having a known composition, whereby artifact-related reconstruction errors may be corrected. The method is characterized in that the changes in intensity are evaluated by modeling the influences of a number of predetermined parameters related to the nature of each phase on the absorption coefficient of the body in one or more spectral bands of the polychromatic radiation. The method is useful for the tomographic analysis of geological samples or the human body.
