DOVE ELECTRONICS, INC., WILL DETERMINE WHAT MECHANISMS/PARAMETERS OF ATMOSPHERIC OPTICAL SCINTILLATIONS ARE SIGNIFICANT AND USEFUL IN MEASURING TURBULENCE AND WIND . THE PROPAGA- TION PATH WILL BE CONSIDERED TO BE LINE-OF-SIGHT. AFTER THOROUGH INVESTIGATION AND DEFINITION OF THESE PARAMETERS, HOLOGRAPHIC FILTERING TECHNIQUES FOR THEIR MEASUREMENT WILL BE STUDIED. THESE TECHNIQUES WILL INCORPORTE V ...

ADVANCED STRUCTURAL MATERIALS USED IN THE FABRICATION OF SUBMARINES CAN SUSTAIN LARGE STRAINS DURING THE FORMATION PROCESS CAUSED BY EXPLOSIVE LOADINGS. THE COMPUTATIONAL SOLID MECHANICS COMMUNITY HAS RECENTRLY RECOGNIZED SERIOUS SHORTCOMINGS IN CALCULATIONS USING MATERIAL MODELS IN THIS LARGE STRAIN REGION. BECAUSE OF THE IMPORTANCE OF CALCULATIONS IN UNDERSTANDING THE SHOCK RESPONSE OF SUBMARINE ...

HYPRES is developing a novel wide-bandwidth SQUID-based amplifier chip for cryogenic particle detectors. A novel approach for implementing a wide bandwidth and inexpensive SQUID readout scheme was recently proposed and demonstrated by Wilty and Martinis at NIST. The SQUID chip integrated in this system is based on a single analog SQUID coupled to an array of SQUIDs. HYPRES is presently producin ...

In the proposed Phase I SBIR program, Aymont Technology and CoolCAD Electronics will design and demonstrate prototype silicon carbide (SiC) avalanche photodiodes (APD) specifically designed for high-efficiency, single-photon counting of 121.6 nm Lyman-alpha photons. This detector will be provided to relevant personnel at NIST for calibration and testing. Both discrete APDs and arrays will be used ...

This is an SBIR Phase II proposal to develop a tactile refreshable computer display prototype (TRCD) that will support multiple tactile alphabets (e.g. ELIA, braille, and Roman), multiple lines of text, and graphics to benefit the more than 1.8 million blind Americans. Commercially available TRCDs are expensive (~$12,000, or $19 per actuator), provide only one line of text (with 640 actuators) and ...

A wireless sensor and actuator network capable of providing precision time synchronization between the nodes of the network will be developed. The IEEE 1451.0 smart transducer interface and IEEE 1588 time synchronization standards will be combined, with additional software and hardware to provide synchronization between the clocks on the Wireless Transducer Interface Modules (WTIM) sensors/actuato ...

Weidlinger Associates Inc. proposes to develop effective technology for simulating explosive detonations within civil buildings where the propagation of airblast and failure of weak internal walls are strongly coupled. We will conduct a field test program designed to complement other internal detonation testing efforts such as DTRA''s Distinct Cobra, expanding the available database. We will perfo ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...
