Cavity Ring-Down (CRD) spectroscopy is developing into a precise tool for measuring gaseous contaminants in ultrahigh vacuum and other environments. Optimum sensitivity is obtained by driving the CRD spectrometer in the mid-IR part of the spectrum with about 100 mWatts of average power at 5 kHz and with pulse lengths of 10-50 nsec. Bandwidths of 100 MHz are required. There are no commercial lasers ...

Development of an optical water level sensor is proposed to solve some of the problems and limitations of current sounding tube/protective well acoustic sensors. By using light instead of sound, temperature gradient effects on the measurement are obviated. Furthermore, the proposed system eliminates the need for a sounding tube, protective well and associated temperature sensors, and does not requ ...

Accurate and timely information about space weather has become essential for managing many technologies on which our lives depend (e.g., radio communications, Global Positioning Systems). A major limitation to accessing this information from NOAA and private vendors is the lack of well-defined, standardized methods for accessing data or running models remotely over the Internet. Northwest Research ...

This SBIR project will research and develop a new class of miniature hyperspectral optical instruments for aquatic monitoring. The approach uses a molded spectrograph of exceedingly small size as the key optical component. This so-called micro-spectrograph can be implemented into a variety of miniature instrument configurations, e.g., as a radiometer, reflectometer, flourometer, and spectophotomet ...

The development of a PC-based stereoscopic imaging and measuring system (SIMS) that will be suitable for underwater applications is proposed. There are three main objectives for the Phase 1 work: 1) to evaluate the requirements (accuracy, range, field of view, speed, potability, etc.) For a field-worthy, video-based SIMS; 2) to modify our existing stereo measurement system to accept video input an ...

SAGE Electrochromics, Inc. proposes to evaluate the feasibility of replacing the indium doped tin oxide (ITO) transparent conductor TC with a thin-film Ag based stack having greatly reduced costs, enhanced performance and improved durability for electrochromic (EC) windows. This new system draws upon low-emissivity technology developed in the architectural glass coating industry to maximize photop ...

Certain algal species have been identified as producing toxins which when ingested can cause illness and death in humans and many marine species. While it is possible and necessary to test for the actual toxins, this proposal describes the development of a rapid DNA probe based test for detection of toxin producing algal species. The test is semi-automated, easy-to-use, requires little technical t ...

For more than three decades, transportation planners have relied on survey data collected specifically for the development of travel forecasting models, which are expensive to collect and maintain on an ongoing basis. There is a plethora of data collected for other reasons that could potentially support transportation planning which is becoming more accessible through technological advances. Use ...

This proposed activity will conduct case studies of six selected United States ports to determine whether an integrated terminal information system in each of them might deliver significant benefits to port operators, port users, and shippers. Using the experience of the railroad industry as a guide, problems and possibilities for integrating information flow will be examined. The final report w ...
