WE PURPOSE TO DEMONSTRATE THE FEASIBILITY OF SPEECH RECOGNITION ON A VLSI NEUROCOMPUTER. THE SPEECH RECOGNITION SYSTEM PERFORMS SPEAKER-INDEPENDENT RECOGNITION OF SPOKEN ENGLISH LETTERS. THE CURRENT IMPLEMENTATION OF THE SYSTEM, NOW RUNNING ON A SUN 4 WORKSTATION, CLASSIFIES LETTERS OF THE ENGLISH ALPHABET AT 94% ACCURACY - THE BEST REPORTED PERFORMANCE OF ANY SYSTEM ON THIS DIFFICULT TASK. THE HI ...

This proposal presents a Phase I SBIR project to develop a high precision, low disperse rate powder disseminator for the US Army. In the development of the sensitive detecting agent, we need to release a precise amount of C&B agents in the controlled detection experiments. However, such a technology does not exist at the present time. After examining existing technologies, we believe that the r ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

We propose to continue the development and characterization of a polymeric nanoencapsulation technology that can increase the lifetime of a protein therapeutic agent within a biological system. The materials have been demonstrated to exhibit no cytotoxicity and to efficiently deliver antibody against Protective Antigen of bacillus anthracis.

We propose that a comparative colorimetric assay be developed that will use a ticket of the same dimensions as the current ANP immunoassay tickets. This will allow the AChE test to be conducted using a similar workflow as the lateral flow immunoassay-based HHAs and be similarly read on the ANP reader to yield an unambiguous result independent of user judgment.

INCREASES IN SOLAR CELL EFFICIENCY CAN BE ACHIEVED WITH TANDEM MULTI-JUNCTION STRUCTURES TO IMPROVE THE PERFORMANCE AND SCALE OF SPACE PHOTOVOLTAIC CONCENTRATORS. THE "TOP SOLAR CELL" TANDEM APPROACH COULD INCREASE ENERGY CONVERSION EFFICIENCY BY AS MUCH AS 100%. A SELF-SUPPORTING ALUMINUM-GALLIUM-ARSENIDE (ALGAAS) TOP SOLAR CELL IS BEING DEVELOPED FOR MECHANICAL ATTACHMENT TO A SILICON CONCENTRAT ...

EXISTING METALLIC-TYPE CONTACTS ON GALLIUM ARSENIDE (GAAS) HAVE NOT BEEN STABLE AT HIGH TEMPERATURES BECAUSE OF INTERDIFFUSION AND/OR ALLOYING OF THE GAAS TOP LAYER. HIGH TEMPERATURE CONTACTS TO GAAS SPACE PHOTOLTAIC CELLS ARE BEING DEVELOPED BASED ON THE FORMATION OF A HIGHLY-STABLE INTERMEDIATE DEGENERATE SEMICONDUCTOR LAYER BETWEEN THE GAAS AND A HIGH TEMPERATURE METAL ALLOY. THE INTERMEDIATE S ...

UNIFORM LARGE AREA, DEVICE QUALITY INDIUM PHOSPHIDE (INP) EPITAXIAL LAYERS ON INSULATING SUBSTRATES COULD LEAD TO THE DEVELOPMENT OF A NEW GENERATION OF PRODUCIBLE, RADIATION-HARDENED MICROELECTRONIC AND OPTOELECTRONIV INTEGRATED CIRCUITS. INP ALLOYS OFFER THE ADVANTAGES OF: PROVEN RESISTANCE TO RADIATION DAMAGE; LOWER SURFACE RECOMBINATION THAN GAAS; HIGH PEAK ELECTRON VELOCITY; AND BANDGAPS THAT ...

HIGH TEMPERATURE (>600 DEGREES CELSIUS) INDIUM PHOSPHIDE (INP) SPACE SOLAR CELLS ARE BEING DEVELOPED TO ELIMINATE THEPROBLEMS, SURFACE DECOMPOSITION AND CONTACT FAILURE, ENCOUNTERED WHEN INP SOLAR CELLS ARE EXPOSED TO HIGH TEMPERATURES. KEY TO THIS PROGRAM ARE THE USE OF AN ENCAPSULANT LAYER TO ARREST SURFACE DECOMPOSITION AND A HIGHLY-STABLE INTERMEDIATE DEGENERATE SEMICONDUCTOR CONTACT SYSTEM DE ...
