Abstract
An apparatus and method utilizing acoustic resonance spectroscopy applicable to any mechanical device or structure having internal or external components that need to be positioned away from a set point and then returned to the original position, such as a valve which is opened to pass fluids and subsequently closed, for noninvasively providing a measure of the deviation from the original position, and for classifying or grouping together objects that appear to be identical from the outside, but which may have slight external or internal differences, such as sealed containers filled with different fluids or materials, are described.
