USING AN ALTO SAXOPHONE WE WILL DESIGN A BRACKET AND A FRAME SYSTEM UPON WHICH WILL BE MOUNTED A SERIES OF ELECTRO-MECHANICAL SOLENOIDS. THE SOLENOIDS WILL BE MOUNTED OVER THE KEYS ON HALF OF THE SAXOPHONE IN ORDER TO BE ABLE TO OPERATE THE KEYS INDIVIDUALLY OR IN GROUPS. THE SOLENOIDS WILL BE CONNECTED TO AND ACTIVATED BY A MECHANISM SIMILAR TO A JOYSTICK FROM A VIDEO GAME. ONLY SIX OF THE TERMIN ...

CYGNUS LASER PROPOSES A REVOLUTIONARY METHOD OF DYNAMICALLY CONTROLLING THE HARMONIC GENERATION PROCESS. PRESENT HARMONIC GENREATION TECHNOLOGY INVOLVES DETERMINING AN OPTIMUM CRYSTAL SIZE AND LENGTH FOR A GIVEN FUNDAMENTAL LASER, THEN USING THE CRYSTAL AS A PASSIVE ELEMENT. THE ONLY AVAILABLE CONTROL MECHANISMS ARE QUITE OFTEN MECHANICAL ALIGNMENT AND TEMPERATURE CONTROL. THE CRYSTAL ACTS AS A NO ...

AT CYGNUS LASER, WE HAVE BECOME CONVINCED THAT NONLINEAR OPTICAL MATERIALS WITH DESIRABLE PROPERTIES FOR HARMONIC GENERATION AND FREQUENCY CONVERSION ALREADY EXIST. IN PARTICULAR, WE HAVE ALREADY DEMONSTRATED A KTP SECOND HARMONIC GENERATOR FOR 1064 NM LASERS IN OUR LABORATORY WITH A CONVERSION EFFICIENCY OF 80%. WE UNDERSTAND IN DETAIL THE PHYSICS OF SECOND HARMONIC GENERATION WELL BEYOND THE SIM ...

LEAD IN SOIL MUST BE TREATED IN ORDER TO REDUCE THE EXPOSURE RISK ASSOCIATED WITH LEAD MIGRATION AND LEAD BIOAVAILABILITY. SINCE THE LEVEL OF LEAD IN CONTAMINATED SOIL IS USUALLY VERY LOW, A COST-EFFECTIVE AND SAFE LEAD FIXATION TECHNOLOGY IS NEEDED. THIS RESEARCH WILL INVESTIGATE A NOVEL LEAD FIXATION TECHNOLOGY BASED ON NATURAL SOIL CHEMICAL REACTIONS WITH ENVIRONMENTALLY SAFE MATERIALS. PHASE I ...

The output mirror is the most important optical component in determining laser beam quality. The mirror of an industrial laser is therefore the critical component of a high value system in a large market. XEMET's technology creates mirrors that not only resist thermal distortion by removing several KW/sq-cm., but also detects distortion and acts to off-set it in real time, holding the mirror shape ...

IN SEPTEMBER OF 1990, A SUBMERSIBLE MIXER WAS INSTALLED IN THE OXIDATION DITCH AT THE GRAND COULEE, WASHINGTON, WASTEWATER TREATMENT FACILITIES. THIS MIXER MAKES IT POSSIBLE TO MAINTAIN MIXING WITH THE BRUSH ROTOR AERATORS OFF, THEREBY CREATING ANOXIC CONDITIONS IN THE DITCH. THE POTENTIAL ADVANTAGES OF THIS PROCESS MODIFICATION INCLUDE ENHANCED NUTRIENT REMOVAL, FILAMENTOUS SLUDGE BULKING CONTROL ...

The concentrator separates sunlight into a focused spectrum, allowing photovoltaic conversion efficiences of 50% or more through the use of several types of solar cells. The project involves generation and high-fidelity replication of surface relief diffractive structures with sub-micron dimensions. NLI's patented replication technology can be used to manufacture low cost, high quality diffractive ...

Removing heat critically limits the application of high power laser diode stacked arrays to many high-value-added commercial markets where they would have commanding competitive advantages, including solid state and gas laser pumping; communications; laser welding; heat treating; alloying; high speed printing and various medical uses. XEMET's technology will remove on the order of 5 KW per square ...

Electronic cooling, micro-chip cooling and advanced materials all suffer from thermal limitations. XEMET micro-filaments used individually or embedded into matrix materials will create new families of products focused on these high-value-added markets. For electronic applications a single XEMET micro-filament 50 microns in diameter is capable of carrying 10 to 20 watts. Embedded into a matrix, the ...
