  • Patent number: 12017739
    Abstract: An apparatus and method for prevention and treatment of marine biofouling on a surface to be treated by the apparatus includes a body defining a cavity, the body terminating in a distal open end that is adapted, in use, to be in the vicinity of a surface to be treated such that the surface forms a first end wall of a chamber within the cavity; an acoustic transducer mounted within the cavity to form an opposite second end wall of the chamber, the acoustic transducer being adapted to cause acoustic pressure fluctuations; and a reservoir for a liquid, the reservoir including an inlet passage and a plurality of mutually spaced outlet passages for liquid flow from the reservoir into the chamber, the outlet passages at least partially surrounding the chamber in the vicinity of the distal open end.

  • Patent number: 11426772
    Abstract: An apparatus for cleaning a surface includes a body defining a cavity and terminating in a distal end that is adapted, in use, to be in the vicinity of a surface to be cleaned such that the surface forms an end wall of a chamber including the cavity; at least one cleaning liquid inlet for flow of a cleaning liquid into the chamber; a divider located in or at the end of the cavity that divides the chamber into first and second portions, the second portion, in use, being in fluid communication with the surface to be cleaned; and an acoustic transducer associated with the first portion to introduce acoustic energy into the chamber; wherein the divider is adapted to permit the passage of acoustic energy therethrough from the first portion to the second portion of the chamber to thereby allow pressure fluctuations to be generated at the surface.

  • Patent number: 9131949
    Abstract: An apparatus, method and system for classifying a shockwave is described, particularly for use in an Extracorporeal Shockwave Lithotripsy (SWL) system. The method for classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment comprises receiving an acoustic signal at a passive unfocused acoustic sensor, determining whether at least one characteristic of the received acoustic emissions exceeds a respective pre-determined threshold value, and classifying the shockwave as effective or ineffective in dependence upon said determination. A method for predicting the outcome of an SWL treatment is also described.
