Patent ID: 6951396

Claim:
An anti-fogging system for preventing condensation of water vapor on a reflecting surface that fogs the reflecting surface when the temperature adjacent the reflecting surface is below the dew point comprising: (a) a mirror having a reflecting surface of sufficient hardness to permit said reflecting surface to be striated such that upon wetting said reflecting surface with water said water will cohere to said striations and form a thin lamina of water on said reflecting surface; and (b) a striating member having surface abrasives of greater hardness than said reflecting surface such that upon rubbing said striating member upon said reflecting surface said reflecting surface will be striated whereby upon wetting said reflecting surface with water said water will cohere to said striations and form a thin lamina of water on said reflecting surface thereby preventing water vapor to condense on said reflecting surface when the temperature adjacent said reflecting surface is below the dew-point.
