Government mandates require federal agencies to purchase digital radios compliant with Project 25 standards, but these new radios do not work with the radios currently in use by the USFS. Significant audio degradation occurs when links are attempted between different radios from different manufacturers. Existing P25 solutions require expensive dedicated circuits and do not meet the needs of the US ...

Luna Innovations will develop an enabling new technology to determine groundwater vector flow between well sites using acoustic propagation. The new capability is derived from Luna's patented ultrasonic phase-locked-loop research that will be scaled to operate at seismic frequencies appropriate for groundwater monitoring. The instrument will operate from small well bores to assess the dynamic and ...

Humidity and moisture are difficult parameters to measure and control in greenhouses and in bulk stored grain. Greenhouse control systems with distributed sensors can manage dynamic environments to enhance crop yield, prevent disease, and conserve energy. Psychrometers are too complex for multi-zone climate control. At high levels of humidity, hygrometers have problems with accuracy, stability, an ...

The trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...

This SBIR program would develop practical methods for the interconnection, addressing and control of large numbers of distributed MEMS-based sensing and actuation elements using optical fiber multiplexing techniques. Such interconnected sensor/actuator arrays have immediate and long-term applications in the instrumentation and control of adaptive aircraft, spacecraft and hydrocraft structures, fl ...

Current battlefield situation displays either lack resolution ir restrict the user's perception to a small segment of the battlefield. Additionally, the plotting of data on these displays is extremely manpower-intensive, consuming valuable personnel resources that could be applied to situation analysis and other important tasks. Trident proposes to design and produce an innovative situation awar ...

Phase I of this SBIR proposal will study the feasibility of ECHO housing accompanied with Home Health Care insurance, as a revenue-generating opportunity for rural communities. The proposed objectives are summarized as follows: 1. To perform three needs assessments in the state of Vermont of homeowners 55 years old and over living in rural areas. To ascertain a. the feasibility of ECHO housing ...

THE RELATIONSHIP AMONG WATER POTENTIAL, HYDRAULIC CONDUCTIVITY, AND WATER CONTENT (P-K-O) ARE SOME OF THE MOST COMMONLY SOUGHT SOIL PHYSICAL PROPERTIES. PREDICTION OF WATER AND SOLUTE MOVEMENT IN BOTH AGRICULTURAL AND ENVIRONMENTAL SITUATIONS IS ULTIMATELY PREDICATED UPON AN ADEQUATE EXPERIMENTAL DESCRIPTION OF POROUS MEDIA. A RAPID AND ACCURATE METHOD TO DETERMINE THESE RELATIONSHIPS WOULD FIND W ...

THE DIFFICULTY IN PREDICTING STRUCTURAL DEGRADATION RATES FOR NUCLEAR POWER PLANT COMPONENTS DUE TO CORROSION AND OTHER FACTORS HAS LED TO THE NEED FOR COSTLY, TIME CONSUMING INSPECTIONS AND INCREASED COST FROM INTENTIONALLY OVERDESIGNED COMPONENTS. THE SITUATION INDICATES A SERIOUS, UNMET NEED FOR A SIMPLE BUT ACCURATE SYSTEM FOR REAL- TIME, IN SITU, NONDESTRUCTIVE ANALYSIS OF NUCLEAR POWER PLANT ...
