ABSTRACT:
An electromagnetic radiation control device is proposed using visually transparent computers and associated components to control the device's optical memory and the characteristics of its active optical component all contained within a capsule. The invention can be applied to items such as eyeglasses, contact lenses, window panes, doors, building panels, mirrors, billboards, light shields, electronic displays (TV, etc), reducers, magnifiers, projection systems, sunlight reflectors, cameras and other lenses, portable transponders for the blind, optical prothesis, and any combination of the above.
