US Patent:

50654292, Nov 12, 1991

Filed:

Oct 14, 1990

Appl. No.:

7/626409

Inventors:

Gerald S. Lang - Silver Spring MD

International Classification:

H04K 100

US Classification:

380 25

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. Information provided on the storage media would include an index table listing the security identification code, the logical zones to which a particular user is assigned as well as a personal security key used in conjunction with a personal security key provided in the smart card. The interaction between the user's personal accessing device and the index table provided on the storage media determine if access is granted as well as access privileges accorded to the user.

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. Information provided on the storage media would include access/information management control device such as index table listing the security identification code, the logical zones to which a particular user is assigned as well as a personal security key used in conjunction with a personal security key provided in the personal access device such as a smart card.

Appl. No.:

8/037445

Inventors:

Robert B. J. Warnar - Germantown MD
Gerald S. Lang - Silver Spring MD

International Classification:

G02F 113

US Classification:

359 85

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.
