ABSTRACT:
A self-cleaning plate shaped device for use in an automotive rear view mirror. The device preferably includes a mirror and a vibrator disposed on the mirror for propagating oscillations in the mirror substantially entirely parallel to the plane of the mirror. The vibrations remove foreign substances from the mirror. The mirror also includes a heater disposed on the back of the mirror for distributing heat substantially entirely throughout the mirror. When the mirror is heated by the heater, a moisture blur or the like are evaporated quickly and removed from the reflecting surface of the mirror. Further, frost, ice and the like is melted into water drops, and removed from the reflecting surface of the mirror due to the vibration of the mirror by the vibrator.
