Abstract:
An acoustic standing wave is utilized to separate components from a multi-component fluid, such as oil from an oil-water mixture, or cells entrained in a fluid, in a fluid flow scheme with an acoustophoresis device. For example, the flow scheme and device allows for trapping of the oil as the oil coalesces, agglomerates, and becomes more buoyant than the water. A driver and controller for the acoustophoretic device accommodate variable loading as the components are separated, thereby improving separation efficiency.

Claim (Index 8):
A method for controlling an acoustophoretic device that uses an ultrasonic transducer to create a multi-dimensional acoustic standing wave, the method comprising:\n driving an amplifier electrically connected to the at least one ultrasonic transducer to send an output signal to the ultrasonic transducer; measuring a first voltage between the amplifier and a predetermined first impedance; measuring a second voltage between the first impedance and the at least one ultrasonic transducer; measuring a current from the output signal between the measured first and second voltages; determining an actual impedance of the ultrasonic transducer from the measured current and measured first and second voltages; and adjusting the output signal from the amplifier to obtain a desired impedance of the ultrasonic transducer.
