CLEARING PRECIPITATION |
| 摘要 |
A method of clearing precipitation from a surface of a window comprises ultrasonically vaporising the precipitation. A vehicle windscreen (10), for example, has transducers (1-8) distributed around the edge and bonded to the windscreen to insonify it. The transducers are energised by a drive system (11 -14 and 121). |
