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 ...

This Small Business Innovation Research Phase I project focuses on developing a novel scaleable process to produce advanced ceramics from agricultural materials such as rice husk cost effectively. Using such a processing approach, several of processing steps used to produce value added ceramics will be eliminated which will lead to a substantial cost reduction. Nanomaterials Research Corporation ...

The world wide communications infrastructure is undergoing dramatic revision, with optic fiber providing virtually limitless bandwidth, and wireless communication connecting increasingly mobile users to that fiber backbone. However, cost-effective evolution to an information-rich society will require strong standardization of wireless communication technology. The United States gave birth to the ...

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 ...

THE FEASIBILITY OF LOW COST REAL TIME SENSORS CAPABLE OF DETECTING AGRICULTURAL SPRAY DRIFT (JORDEN, 1993) AND SOLID AIRBORNE PARTICLES (JORDEN 1992) HAS BEEN DEMONSTRATED. WHILE THESE DEVICES ARE VERY EFFECTIVE IN THEIR PRESENT FORM, THEY CAN BECOME MORE ACCURATE AND VERSATILE IF THEY ARE ABLE TO SAMPLE LARGER VOLUMES OF AIR. THIS CAN BE ACCOMPLISHED BY ROTATING THE SENSORS THROUGH THE AIR AT A H ...

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 ...
