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.

Abstract: A method and apparatus for granting privileges for securely and selectively retrieving material such as data and databases, messages and other textual information, graphics, tables, analogs such as maps, facsimiles (FAX) of all manner of transmitted materials, audio such as voice or speech and music, video, images, and photographs, provided on storage media utilizing information encoded in the storage media. The storage media are included in one or more reading devices associated with a computer or computers. A storage retrieval device, such as a smart card, is used in conjunction with the computer to determine whether information retrieval by a particular user to specific storage media is granted. The storage media can be sub-divided into a plurality of logical zones and access to all or a portion of the material on the storage media is granted based upon the logical zones to which the user is allowed information retrieval.

Abstract: A method and apparatus for granting selected access to material such as data and databases, messages and other textual information, graphs, tables, maps, facsimiles (FAX) of all manner of transmitted materials, audio such as speech and music, video, images, and photographs, provided on storage media utilizing information encoded in the storage media. The storage media are included in one or more reading devices associated with a computer. A storage accessing device, such as a smart card, is used in conjuction with the computer to determine whether access to a particular user to specific storage media is granted. The storage media can be sub-divided into a plurality of logical zones and access to all or a portion of the material on the storage media is granted based upon the logical zones to which the user is allowed access.
