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 ...

A new type of compact induction accelerator currently under development at the Lawrence Livermore National Laboratory (LLNL) promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators and advanced dielectric materials and switches. The system, called the Diel ...

New innovative technology for the visually impaired has been developed by NIST. If commercialized, it would provide refreshable tactile graphical information to the visually impaired, enabling them to compete on a more equal footing in the workplace and the education system.

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 ...

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 ...

Predicting the response of building components to internal detonations is more complex than the corresponding task for external loads because of the more complex loading waveforms which include multiple reflections in the shock phase followed by a long duration pseudostatic loading that depends upon room venting. Add the possibility of additional impulsive loading from primary debris. We propose t ...

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 ...

The most practical arrangement for investigating moving fires within a restricted space is to use a high- resolution stand off technique. One such method that fits this description is the use of a staring infrared (IR) sensing device (i.e. imager).
