Mirror assemblies incorporating variable index of refraction materials
First Claim
Patent Images
1. A method for focusing an image, comprising:
- providing a mirrored device having both a reflective surface and a focusing element spaced apart from the reflective surface, the focusing element having a plurality of pixelated regions;
changing an index of refraction of the focusing element in response to a signal from a sensor to focus an image for an observer; and
providing the observer with a first image on a first focal plane and with a second image on a second focal plane.

Abstract
A mirror assembly including an active lens and a reflective surface. The mirror assembly may change its refractive index when a voltage is applied to the active lens, thereby changing the field of view in the lens. Exemplary applications include a blind spot system in a motor vehicle, in which, upon sensing another vehicle in a driver'"'"'s blind spot, the mirror assembly changes the driver'"'"'s field of view to include the blind spot. Additional applications include a magnifying mirror for shaving or applying cosmetics.

2. A method for focusing an image, comprising:
-
providing a mirrored device having both a reflective surface and a focusing element spaced apart from the reflective surface, the focusing element having a plurality of pixilated regions; changing an index of refraction of the focusing element in response to a signal from a sensor to focus an image for an observer, wherein the changing comprises changing the focal point of the image.
