Clearing precipitation |
摘要 |
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. |

1. A method of clearing precipitation from a surface of a window, the method comprising ultrasonically vaporizing the precipitation using an ultrasonic wave produced by one or more piezoelectric transducers distributed around one or more edges of the window, wherein the one or more piezoelectric transducers insonify the window with the ultrasonic wave, wherein ultrasonic wave is one or more of a surface wave, a Rayleigh wave and a Lamb wave having a frequency in the range 0.5 to 5 MHz. |
