MARINE ANTIFOULING RESONANCE SYSTEM

摘要

The present invention comprises an ultrasonic anti-fouling arrangement for an aquatic structure, the anti-fouling arrangement comprising at least two ultra-sonic transducers, the anti-fouling arrangement comprising at least two ultra-sonic transducers, at least one ultrasonic receiver, a transducer driver and a controller; wherein the transducers are acoustically coupled to the structure, whereby, in operation, ultrasonic vibrations can be transmitted, at least in part, through the structure; wherein the ultrasonic receiver is operable to detect ultrasonic signals to provide a response signal, the controller being operable to provide a control signal for the transducer driver whereby each transducer can be driven within a range of operating frequencies and operating voltages and wherein the controller can determine feedback from a response signal provided by the at least one ultrasonic receiver; whereby subsequent operation of the transducers is determined from such feedback.
