Abstract: A cryptographic system makes everyday data objects, such as a document or conversation, unreadable to anyone other than the owner or those currently having permission to access the data objects. The cryptographic system is transparent by requiring no additional effort on the part of any user in the encryption/decryption process other than entering a user identifier and password. Each document is encrypted with a unique encryption key. Changes to data object access permissions are immediately honored and enforced by enabling or disabling access to certain decryption keys. Decryption of data objects requires information known only to the owner of the data object or those permitted to access the data object. This decryption information is not stored anywhere in the system.

Abstract: A deflection mirror tower (DMT) of a multiple-disk array, optical storage system includes a plurality of prism members, each having an angular mirror surface, arranged along a vertical axis of the DMT and configured at a predetermined angular orientation to deflect a laser beam to a respective disk surface. The DMT is generally fabricated using a two-level partitioning process. Several prepared glass substrates, i.e., one for each mirror type, are initially sliced into bars having predetermined geometries. A bar from each substrate is sequentially aligned to a master reference and bonded to adjacent bars to form an intermediate bar stack. The stack is then segmented into a plurality of DMT components, each having a plurality of prism members.

Abstract: A keyless electronic calculator includes an optical bar-code reader for entering bar-coded program information, in the form of data and individual commands or complete programs, into the calculator. The calculator also includes a read-write memory unit (RWM) for storing the entered information, a central processing unit (CPU) having a read-only-memory unit (ROM) with pre-stored routines for processing data by executing the entered commands or program under control of the ROM routines, and a display unit for displaying entered data and execution results. An alternative embodiment of the calculator includes both an optical input means and a keyboard.
