Abstract: A computer or communication system having physically secure vault means which include data source, receiver and decoder-encoder (cryptosystem). Data outside the vault means is coded and thereby protecting its loss from electronic tapping. Clear data inside the vault means is protected by the vault.

Abstract: A system which detects the presence and bearing of a mass M implemented by having a first field or wave interact with the motion of a charged mass m to produce a second field or wave which is modulated by the tidal effect of mass M. The second field or wave with unique tidal signal is then detected. The system can be implemented as a magnetic resonance spectrometer, gyrotron, cyclotron, Fourier Transform-Mass Spectrometer (FT-MS), or even as a large spinning mass and permits the substantial increase in the sensitivity of practical gravitational mass detectors and gradiometers and thereby permitting the detection of earthbound objects such as ore deposits, ships, submarines, tanks, artillery, and small concealed handguns and may extend gravitational mass detection capabilities to space and galactic objects.

Abstract: Apparatus and method for a holographic identification system used to determine the presence and identification of objects with tags and labels placed on persons, articles, goods, merchandise, documents, credit cards, identification cards and the like. The apparatus comprises holographic means for encoding and decoding tags and labels with ordinary incoherent light. The method comprises the steps of holographically encoding tags and labels, attaching labels to objects, and holographically decoding tags and labels wherein the encoding and decoding is done with incoherent light.

Abstract: A system for measuring angles, including a lens or antenna for focusing the radiation from an object scene onto an image sensor which is shifted by a clock, thereby producing the real time imaging of the object scene wherein each element of the object scene is detected as a pulse, representing the element angular displacement from the lens, at the output of the image sensor. A system for measuring angles of objects relative to the centerline of a lens or antenna. A goniometer for measuring the bearing of objects. A system for measuring the vector speed of objects. A velocity meter for measuring the speed of objects. A system for tracking objects. A system for motion compensation. A search, track or track-while-scan detection system. Without the lens or antenna, a system for recording and reproducing halograms.

Abstract: A computer having a plurality of interconnected IC chips. Chips include a transceiver for sending and receiving signals from other chips. By implementing on-chip transceivers, the communication between chips in the computer is done with fewer wires.

Abstract: Apparatus and method for a thermoelectric generator which converts heat directly from a heat source into electrical energy. This is done by applying an external electromotive force (emf) across a heated semiconductor to produce the drifting of electrons and thereby producing a current in the semiconductor which can be used in a load. Operation is possible at maximum power, maximum efficiency near unity, or at high combined power and efficiency. When used separately or in combination with a concentrating lens or combination of a heat absorber and heat exchanger there is provided a system for converting the sun's energy to electricity. When used in combination with a heat absorber and heat exchanger there is provided a system for converting fossil, nuclear, and geothermal heat energy to electricity.

Abstract: A recursive filter characterized by increased efficiency and accuracy and incorporating a step decision circuit which reduces filter noise, error and size. Efficiency is obtained by reducing the requirement for bulk memory and the number of multipliers while accuracy is obtained by reducing error portions of data and coefficient words in the filter.
