Intelligent Multi-Sensor Control Systems to Manage Lighting

Technology is needed to generate a change in the ambience of a given space. The technology must interpret a number of sensory changes within a room in order to change other parameters. Of specific interest is software that interprets multi-sensor data and the consequence hardware to control numerous devices to bring about a desired lighting change.

Microbial-Based Lawn-Care, Pond-Care, and Cleaning Technologies

Proprietary microbial systems use naturally occurring microbes in lieu of chemicals in fertilizers, microbial inoculants, cleaning products, and pond treatments. Products are based on incorporating beneficial micro-organisms with a variety of task-specific organic surfactants, microbial nutrients, fertilizers, cleaning agents, and bio-polymers. The micro-organisms produce enzymes that continue to work even after cleaning, or — in the case of lawn and pond care — continue to make the soil or pond healthier even after fertilizing the plants or inoculating the water.

Fly-by-Wireless: A Less-Wire and Wireless Revolution for Aerospace Vehicle Architectures

By George Studor, NASA’s Johnson Space Center, Houston, TX Every ounce of weight brought to the lunar surface costs 40 to 60 times that in fuel needed at liftoff from the Earth. Part of that weight penalty is due to wires, but the cost of wires is much more than weight. Wired connectivity drives up the price of design from the beginning: it drives the cost of the many systems and structures; it drives inspection, troubleshooting, maintenance, and upgrade costs; as well as the cost of making system changes. Future vehicles that can reduce the effects and limitations of wires will not be without risk or a lot of work, but the effort has begun.

Analytical Technique for Healthcare and Industrial Applications

Aria Analytics is commercializing a novel analytical technology to characterize liquids for healthcare and industrial applications. As a drop of liquid evaporates on the vibrating quartz sensor, it undergoes distinctive phase changes representing the unique chemical and physical characteristics of the sample. This unique “fingerprint” represents information that is not readily available from any combination of analytical methods currently in use.

Fiber-Optic Determination of N2, O2, and Fuel Vapor in the Ullage of Liquid-Fuel Tanks

A fiber-optic sensor provides feedback control of onboard inert gas generation systems (OBIGGS) and reduces aircraft operational costs. A fiber-optic sensor system has been developed that can remotely measure the concentration of molecular oxygen (O2), nitrogen (N2), hydro- carbon vapor, and other gases (CO2, CO, H2O, chlorofluorocarbons, etc.) in the ullage of a liquid-fuel tank. The system provides an accurate and quantitative identification of the above gases with an accuracy of better than 1 percent by volume (for O2 or N2) in real-time (5 seconds). In an effort to prevent aircraft fuel tank fires or explosions similar to the tragic TWA Flight 800 explosion in 1996, OBIGGS are currently being developed for large commercial aircraft to prevent dangerous conditions from forming inside fuel tanks by providing an “inerting” gas blanket that is low in oxygen, thus preventing the ignition of the fuel/air mixture in the ullage.
