Abstract: In one aspect, a method and system for detecting a change in fluid dynamics of a fluid flowing through an extra-corporeal circuit is disclosed, which includes establishing an acoustic wave resonance across a transverse dimension of at least a portion of a line associated with the extra-corporeal circuit through which the fluid flows, monitoring a phase signal of the resonant acoustic wave, and identifying occurrence of a change in fluid dynamics of the flowing fluid when the observed phase signal of the resonant acoustic wave indicates a deviation from the expected fluid flow signature. The change in fluid dynamics can be used to indicate a venous needle dislodgement event.

Abstract: An acoustic apparatus and method for using a combination of low-frequency and high-frequency vibration of dried food, grain being an example, such that there are a large number of collisions among the individual grain particles for destroying microorganisms that reside on the surface or just below the surface of the grain, are described. Embodiments of the invention permit bulk and continuous processing of the food. It is expected that such collisions do not produce any chemical changes in the food, nor should it have any adverse effects on the taste thereof. Embodiments of the apparatus are applicable to destruction of airborne microorganisms.

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 dosed, for noninvasiveiy 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.

Abstract: Apparatus and method for separating oil from water in produced oil without requiring large separation tanks in which the fluid is heated, using a simple, energy efficient separation process, are described. Centrifugal forces, by themselves, are not effective for completely separating a two-component fluid, especially when the densities of the fluids are similar, such as for heavy oil. By combining both primary and secondary acoustic forces, and taking advantage of centrifugal forces from fluid flow, such that acoustic radiation forces initiate the process of droplet accumulation, and contribute to droplet coalescence, centrifugal separation is enhanced.
