  • Ultrasonically clearing precipitation
    Patent number: 10207300
    Abstract: A system for clearing precipitation from a window comprises one or more transducers (1-8) fixed to the window. The transducers are driven by a generator (13) to produce surface acoustic waves that propagate through the window. The window may be a laminated window such as a windscreen (10) for a vehicle. A sensing system (122) may be used for detecting the presence of precipitation to actuate the clearing system.
    Type: Grant
    Filed: May 3, 2018
    Date of Patent: February 19, 2019
    Assignee: EchoVista GmbH
    Inventors: David Robert Murray Trevett, Patrick Naven Trevett

  • Clearing precipitation
    Patent number: 9316436
    Abstract: A method of clearing precipitation from a surface of a window comprises ultrasonically vaporizing the precipitation. A vehicle windscreen, for example, has transducers distributed around the edge and bonded to the windscreen to insonify it. The transducers are energized by a drive system.
