Abstract: A cavitation assembly for purification of drinking water includes a generally cylindrically-shaped open-ended tube for flow of water therethrough, the tube comprising a transducer for converting electrical energy to acoustic energy and transmitting ultrasound through the water in the tube to induce cavitation in the water in the tube. A water moving means flows the water through the tube, and an electrical power source provides electrical power to the tube. The cavitation inactivates microorganisms in the water.

Abstract: A ballast water monitoring and reporting system for seagoing vessels includes a sensor for monitoring a selected parameter of a ballast water system component and transmitting an electronic signal indicative of a condition of the parameter, a distal acoustic modem for receiving the signal from the sensor and for transmitting an acoustic signal equivalent to the electronic signal received, a shipboard metal structure extending substantially throughout the vessel and adapted to carry the acoustic signal, a proximal acoustic modem adapted to receive the acoustic signal from the metal structure and to transmit an electronic equivalent thereof, and a shipboard data acquisition computer adapted to receive the electronic signal from the proximal acoustic modem and to generate at least one of a display, a report relative to the selected parameter, and a recording of data relative to the selected parameter.
