A long standing problem in oceanography and hydrography is accurate real-time measurement of offshore water levels. The Phase 1 research involved investigating a wide range of recent techniques and technologies, and performing analyses and trade-off studies to evaluate, select, and integrate them into a GPS-tracked buoy system (buoy, shore reference station for differential GPS, and repeater stati ...

We propose an uncooled infrared detector for the 8 to 12 micron wavelength range utilizing an integrated image converter with a thermal sensitivity as small as 2 millidegK based on modeling by independent research groups. Highly stable thin films coupled to a silicon readout additionally provide the desired spatial uniformity, linearity, dynamic range, and reduced cost for the detector representin ...

Based on the outline for a theory of intelligence, and using NIST's hierarchical real-time control system (RCS) architecture, in Phase I, we developed proof-of-concept OpenSim and OpenAnimation toolboxes consisting of the following innovations, namely, (i) Simulation and Animation Software Design that will seamlessly interface with RCS Hierarchy, (ii) Knowledge hierarchy consistent with the f ...

As more and more information is stored digitally and transmitted over the Internet, data and communication security becomes an ever more severe problem facing the military, the government and the financial industry, both for the United States and for all other developed countries. The need for data encryption technology is most urgent. One of the key technologies involved is the generation of trul ...

This Phase I SBIR research project will investigate the feasibility of an ammonia sensor based on an antimonide laser and an advanced, low noise modulation spectroscopy method. The rapid response and high sensitivity will allow the use of the eddy correlation method to provide continuous measurement of ammonia flux. Minor adjustments to the laser operating point will allow the instrument to measur ...

The ability to perform in-situ measurements of oxygen concentration in fire environments at a fast rate (better than 1 sec ) is not fulfilled by available sensor systems in the marketplace. Current systems involve extraction of gas samples with the required removal of water, particulate, and interfering chemical species, which can take several seconds to complete, prior to passing the samples to a ...
