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, the focusing element having a plurality of pixelated regions; and
changing an index of refraction of the focusing element to focus an image for an observer.

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.
