The objective is an optical periodontal probe tailored to automatically measure and record multiple tissue parameters deemed important for disease detection and treatment monitoring. As a first step in the development of a multi-functional device, a probe designed to mimic the visual measurements made by dental clinicians to determine pocket depth, bleeding on probing (BOP) and tissue coloration w ...

Herein, an innovative aircraft weighing system based on a set of piezopolymar film pad sensors is described. The wieghing system, which would operate automatically as the aircraft taxi over it, would be unobtrusive, accurate, and reliable. These sensor pads could be integrated into the flight deck surface below the grated rubber surface finish. These thin (20-30 mils) piezopolymer sensing pads ...

Light scatter has been used to map and size particles on silicon wafers for many years, producing accurate maps of particle position and giving an indication of particle size, but do not reveal any information about particle composition. Today's technology is limited by noise, precluding detection of the smallest particles of interest. Present instruments are not adequate for the next generation ...

THE ADVANTAGES OF THERMOPLASTIC MATRIX COMPOSITES FOR MANUFACTURING LOW-COST CMPONENTS HAVE YET TO BE REALIZED. AN IMPORTANT FACTOR LIMITING THERMOPLASTIC COMPOSITES IS THE LACK OF LOW-COST METHOD FOR PRODUCING HIGH-QUALITY PREPREGS AND PREFORMS. A METHOD OF PRODUCING THESE MATERIALS THAT IS COMPATIBLE WITH COMMONLY USED COMPOSITE FABRICATION TECHNIQUES SUCH AS FILAMENT WINDING, PULTRUSION, AND PR ...

The Joint Surveillance System Computer-Communications System (C-CS) provides mission-critical support to Region Operations Control Centers (ROCCs), Sector Operations Control Centers (SOCCs), and North American Aerospace Defense Command (NORAD). New mission requirements (drug interdiction) and new sensor/system developments exceed the scope of the original design and mission of the C-CS. As a resu ...

THE POSSIBILITY THAT ATOMIC CHLORINE CONCENTRATIONS IN THE MARINE SURFACE LAYER ARE LARGE ENOUGH TO COMPETE WITH OH AS THE MAJOR TROPOSPHERIC OXIDIZER HAS RECEIVED CONSIDERABLE SPECULATION. CHLORINE ATOMS PARTICIPATE IN THE OXIDATION OF HYDROCARBONS AND DIMETHYL SULFIDE AND CAN ALSO DIRECTLY INFLUENCE TROPOSPHERIC OZONE LOSS THROUGH CATALYTIC CYCLES WITH C1O AND HO2 RADICALS. THE NET EFFECT ON T ...

High intensity cooling of expansion turbine blades is proposed, using a self-stabilized evaporation/condensation process within each blade. The result is low blade structural temperature, with waste heat delivered to a low pressure air flow. This is a key technology requirement for development of a fully cooled gas turbine, with potential for operation at radically increased turbine inlet temper ...
