The Smart Flow system developed by NIST provides a platform to develop standards that promote the interoperability of devices produced by different manufacturers. The NIST system can acquire and process multiple sensor data such as voice and image in real-time. Many applications such as speaker verification, head trackers, etc. can be implemented under the framework. In Phase 1, we have demonstrat ...

Oceanit showed the feasibility of a low-cost, compact, lightweight, eye-safe LIDAR suitable for aerosol gradient detection in a Phase 1 effort. The system is based on an eye-safe laser being developed at Oceanit as part of a 3D scanning ceilometer. The laser can operate at greater power than other systems using non-eye-safe wavelengths, thus it eliminates many of the problems associated with low ...

This Phase II SBIR Research project will continue the development and testing of an innovative instrument for measuring fluxes of atmospheric ammonia to be delivered at the end of Phase II. The instrument will combine advances in diode laser technology with sophisticated laser modulation methods to quantify ammonia in a low pressure flow cell. The instrument¿s small size and light weight will ...

The potential for accidents in harbors increases with traffic density. Collisions with other ships or natural obstacles are caused by incorrect controls manipulation by the master in response to some unexpected situation, especially when in a new environment. Continual training for various critical situations on simulators that include realistic topography and the presence of other maneuvering ve ...

The research proposed herein in intended to solve two problems, namely (1) to define a specification framework for access control policies that enables policy composition for both centralized and distributed systems in a precise and systematic manner, and (2) to explore the impact of different security architectures on policy composition. Although most commercial systems support applications that ...

A growing number of fire fighters are suffering third degree burns; this has led to questions about the adequacy of thermal protective performance (TPP) measurements for protective clothing. A new heat flux sensor, whose response approximates that of skin, will be developed to provide better measurements of heat transfer in TPP tests. This sensor will be used with nonlinear parameter estimation an ...

The proposed research will develop the specifications and design of a ceilometer capable of scanning in three dimensions to detect clouds within a range of 75,000 feet (about 15 miles). The final design will be based upon the Vaisala CT-75k ceilometer which has a nominal range of 75,000 feet. As a proof-of- concept, the proposed research effort will use the Vaisala CT-25k (which has a nominal rang ...

Critical issues associated with the design of a rugged, compact "real time" sampling system using photoconductive switches as the signal generator and sample will be investigated. The design concept is based upon an optoelectronic equivalent time sampling principle developed by the Principal Investigator. It involves first the phase locking of the temporal waveform to be measured to the optical pu ...

The near-field scanning optical microscope can supply information on the shape and electrical properties of surfaces with nanometer resolution. The quantitative interpretation of images is difficult because of the difficulty of electromagnetic field solutions in the near-field limit. We propose to supply software to aid in this analysis. The finite-element programs generate two and three-dimension ...

Terahertz radiation is an ideal candidate for non-invasive interrogation of concealed objects and substances. As such, there is an increased need for reliable high-quality nonlinear materials for the generation and detection of THz radiation. Zinc telluride (ZnTe) and gallium phosphide (GaP) are the materials of choice for this purpose. However, the performance of these materials varies widely fro ...
