We propose to investigate the use of new three-layer metallization schemes for wire bond pads to improve the reliability of wire bonding interconnects used in high temperature silicon carbide electronics. Current wire bonding technology does not have the ability to survive elevated temperatures (500" C) for extensive periods of time without failure by several mechanisms which include corrosi ...

IMAGING SPECTRORADIOMETERS COMMONLY USE A POLYCHROMATOR TYPE INSTRUMENT IN CONJUNCTION WITH AN IMAGING ARRAY. SUCH INSTRUMENTS ARE LARGE IN SIZE AND WEIGHT, AND REQUIRE DELICATE ALIGNMENT OF THE DISPERSION ELEMENT IN RELATION TO THE ARRAY. A NOVEL CONCEPT USES NO DISPERSION ELEMENT BUT A PROPRIETARY ANAMORPHIC OPTICAL SYSTEM, AND A SPECIAL DATA REDUCTION ALGORITHM, PRODUCES A PERMANENTLY ALIGNED, ...

BEAMFORMING METHODS IN WHICH THE FAST CONVOLUTION TECHNIQUE IS APPLIED TO EXECUTE MULTICHANNEL TIME DELAY FIR INTERPOLATION FILTERING IS THE SUBJECT OF THIS PROPOSAL. THE METHOD OFFERS THE POTENTIAL FOR EXECUTING CERTAIN PRIOR AND POST BEAMFORMING FIR FILTER-ING OPERATIONS WITHIN THE BEAMFORMER PROCESSING TO ENHANCE OVERALL SYSTEM COMPUTATIONAL EFFICIENCY. TWO FAST CONVOLUTION METHODS BASED ON DIF ...

Large field-of-regard (FOR) scanners are often desirable for poassive and active optical-infrared (IR) sensor systems for applications such as imaging, ladar, precision munitions, space-based surveillance, security surveillance, remote sensing, and free-space optical communications. The large FOR scanners for precision munitions need to be fast, small, light, rugged, low in power consumption, and ...

Computing technology (as well as control and display technology) is rapidly becoming more powerful, miniaturized and wearable. These trends will allow Navy personnel to be increasingly mobile, not tethered to hardwired console and computer systems. In conjunction with wearable display systems, wireless LANs, and alternative control mechanisms (such as voice recognition), system operators may, ...

The objective of the proposed study is to address technology issues associated with tradeoffs between costs and requirements for a system capable of providing weapon impact assessment data that show the location of impact of a weapon relative to an intended target and warhead function. The study will address: (1) night time and adverse weather imaging; (2) data link range and robustness; (3) airc ...

THE REQUIREMENTS OF THE NAVY FOR ITS NEXT GENERATION HIGH SPEED DATA TRANSPORT NETWORKS ARE RAPIDLY OUTSTRIPPING THE CAPABILITIES OF COAXIAL CABLES. FIBER OPTICS INHERENT ADVANTAGES ENABLE NEW NETWORK CONFIGURATIONS TO INTEGRATE MIXED MEDIA (VOICE, VIDEO, DATA, ETC.) WITH VARYING DATA RATES (KBITS/S TO GBITS/S) INTO A SINGLE NETWORK. IN ADDITION, WAVELENGTH DIVISION MULTIPLEXING (WDM) GIVES FUTURE ...

A Phase I and Phase I option research program is presented which is designed to provide the DOD, DOT, and aircraft manufacturers with a valuable design tool to help improve water impact survivability. It is recognized that impacts into water can be more deleterious to structure and occupants as compared to similar accidents on rigid terrain. The proposed program involves the use of existing c ...

The objective of this study is to provide state-of-the-art crashworthiness engineering to better protect the occupants of Naval helicopters which crash into the sea. To date, crash dynamic analysis and crash design criteria have been based mainly on rigid ground impacts and are therefore not of real use to the Navy, where nearly 90 percent of crashes occur into water. When a helicopter cras ...
