CONVENTIONAL LIGHT GAS GUNS (LGG) ARE DESCRIBED, AND VARIANTS TO OBTAIN HYPERVELOCITY PERFORMANCE OUTLINED. CONCLUSIONS FROM RECENT CONTRACTS TO EVALUATE THE FEASIBILITY OF LGG IN AIR-TO-GROUND WARFARE ARE PRESENTED SHOWING THE DIFFICULT TECHNICAL CHALLENGES ASSOCIATED WITH A CONVENTIONAL LGG. THE WAVE GUN CONCEPT IS ADVANCED THAT AVOIDSTHE PROBLEMS OF A CONVENTIONAL LGG THROUGH AN ALTERED INTERNA ...

THE IDENTIFICATION OF THE TYPE OF PRECIPITATION (RAIN, SNOW, FOG/HAZE, HAIL) HAS TRACTIONALLY RELIED ON HUMAN JUDGMENT. RECENTLY, THE WAVE PROPAGATION LABORATORY OF DEVELOPED A TECHNOLOGY FOR AUTOMATIC WEATHER IDENTIFICATION USING LASER SCINTILLATION AND SCATTERING. THE TECHNIQUE HAS BEEN SUCCESSFULLY TESTED IN FIELD OPERATION. HOWEVER, THE SYSTEM IS TOO CLUMSY AND EXPENSIVE FOR LARGE-SCALE FIELD ...

A PARTICULARLY CHALLENGING AREA FOR THE APPLICATION OF MILITARY COMPUTER SYSTEMS IS THOSE CASES IN WHICH THE SYSTEM MUST OPERATE AUTONOMOUSLY IN A HOSTILE OR REMOTE ENVIRONMENT FOR MANY YEARS. ONBOARD SATELLITE COMPUTER SYSTEMS ARE A GOOD EXAMPLE OF SUCH AN APPLICATION. THE PROPOSED EFFORT WILL RESULT IN A NEW GENERATION OF RECONFIGURABLE, DISTRIBUTED COMPUTING SYSTEMS WHOSE ARCHITECTURE CAN BE AD ...

THE MEASUREMENT OF THE RETROREFLECTIVITY OF PAVEMENT MARKINGS OR TRAFFIC STRIPING HAS BEEN LIMITED BY THE INSTRUMENTATION AT PRESENT. THE MAJORITY OF THESE INSTRU- MENTS ARE HAND-HELD PORTABLE UNITS WITH LIMITED GEOMETRY ANDNEASUREMENT AREA. MOBLE UNITS BUILT BY SOME STATES ALSO ARE LIMITED IN THEIR PERFORMANCE BY STRAY LIGHT, NON-OPTIMUM GEOMETRY AND OTHER PROBLEMS. A NEW RETROREFLECTOMETER IS PR ...

IT IS PROPOSED TO EXPLORE THE FEASIBILITY OF ADDING ADAPTIVE AND STOCHASTIC FEATURES TO A CONTENT-ADDRESSABLE MEMORY (CAM) IN SUCH A MANNER THAT THE DEVICE BECOMES CAPABLE OF LEARNING FROM INSTRUCTION AND EXPERIENCE. THE ALGORITHM OF THE ADAPTIVE STOCHASTIC CONTENTADDRESSABLE MEMORY (ASCAM) IS THE SAME AS THAT OF ADAPTIVE NEURAL NETWORKS, VIZ., ITERATIVE THRESHOLDED MATRIX-BINARY VECTOR MULTIPLICA ...

HIGH CONDUCTIVITY IN MATERIALS IS CREATED BY THE ENCAPSULATION OF MICRO-SIZED HEAT PIPES WITHIN THE MATERIAL ITSELF. THE WROUGHT MATERIALS CONTAIN CAPILLARIES WHICH ARE PERFECTLY STRAIGHT, IN REGULAR ARRAYS, CAN BE FORMED IN ANY SHAPE, HAVE OPEN AREAS AS LARGE AS 70%, AND DIAMETERS AS SMALL AS 0.0004 INCH. USED AS HEAT PIPE ARTERIES AND VAPOR SPACES, AND TO FORM WICK STRUCTURES, HEAT PIPE CROSS-SE ...

Berkeley Optics Corp. conceived a novel idea that could reduce the cost of optical fiber connectors and couplers dramatically. In the invention, the core of the fiber is gradually enlarged into a cone-shape (called "core-extension") . The core-extension is made by immersing the output end of a fiber in a UV-curable polymer, and then coupling UV light into the input end of the fiber. The UV light d ...

We propose to build a database system based on 3-D holographic memory disks. The storage capacity of the proposed system is 4 terabits per disk. In addition, all the data within the database can be searched in 80 seconds, an equivalent readout rate of 50 gigabits/second. In comparison, to search through a conventional optical disk based database of 4 terabits would require 4.7 days. The recording ...

Dense arrays of high-frequency photonic devices could provide many advantages to several Department of Defense systems currently under development. One example is their usage in phased-array radar systems. However, crosstalk from one device to the next must be kept at very low levels in order to not degrade the system performance. Often, crosstalk levels are required to be less than -100 dB electr ...

Concurrent engineering is the simultaneous design of process and the control system to improve equipment development. Integrated Systems Inc. (ISI) proposes to create a software design tool for integration of a high fidelity simulation and model- based process control algorithms for semi-conductor equipment processes and apply it to a rapid thermal processing (RTP) chamber. In particular, it is pr ...
