This Small Business Innovation Research (SBIR) Phase II project will create a Dynamic Tactile Display (DTD) prototype with the look, feel, and functionality of the real-world product, and it will demonstrate that the DTD makes it easier to learn and use computers than existing screen reader technology. An in-home trial study will allow a group of users to have the DTD over an extended period of ...

THIS PHASE I EFFORT WILL APPLY THEORETICAL METHODS BASED PRINCIPALLY ON CAGNIARD'S FORMALISM (PREVIOUSLY INCORPORATED BY US INTO OUR POWERFUL SWREF CODE), TO THE PROPAGATION AND FOCUSING, IN BOTH REFLECTIVE AND PHASED-ARRAY EQUIPMENT, OF SHOCK-WAVES PRODUCED BY UNDERWATER SPARKS. THE OBJECTIVE IS TO INVESTIGATE AND PROVIDE DESIGN DATA FOR LITHOTRIPSY EQUIPMENT IN WHICH FOCUSED SHOCK WAVES ARE USED ...

RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

THE PRINCIPAL OBJECTIVES OF THIS PROPOSAL ARE (1) TO EVALUATE A NOVEL BACILLUS HOST-VECTOR SYSTEM FOR THE CLONINGAND EXPRESSION OF GENES SPECIFYING MICROBIAL INSECTICIDAL ACTIVITIES; AND (2) TO DETERMINE THE FEASIBILITY OF AN INTERGENIC CONJUGAL TRANSFER SYSTEM FOR MOBILIZING RECOMBINANT PLASMIDS BETWEEN A VARIETY OF GRAM-POSITIVE HOSTS. A DELTA-ENDOTOXIN GENE FROM A PROTOTYPE STRAIN OF BACILLUS T ...

ETCI WILL INVESTIGATE THE TECHNICAL FEASIBILITY OF USING A MIXED-LIQUID ELECTROSTATIC COALESCENCE METHOD FOR THE SEPARATION OF MICRONIZED PARTICLES OF DIFFERING SURFACE CHARACTERISTICS. THE PROPOSED METHOD USES EMULSIFIED WATER AS A GETTER SELECTIVE TO HYDROPHILIC PARTICLES SUSPENDED ALONG WITH HYDROPHOBIC PARTICLES IN ORGANIC LIQUIDS SUCH AS KEROSENE AND FUEL OIL. IN THE ELECTROCOALESCE PROCESS, ...

LOSSES RESULTING FROM GYPSY MOTH DEFOLIATION IN THE N NORTHEAST IN 1981 WERE $764,000,000. (USDA APHIS 1981). THIS PEST IS DISPENSING AT ABOUT 500,000 ACRES PER YEAR DESPITE LARGE SCALE CHEMICAL SPRAYING. THE OBJECTIVE OF THIS RESEARCH IS TO DETERMINE TH FEASIBILITY OF COMBINING THE RELEASE OF PARASITES, GLYPTAPANTELES FLAVICOXIS AND THE APPLICATION OF THE BIOLOGICAL INSECTICIDE,]I[_ BACILLUS THUR ...

CHEMICALLY CONTAMINATED AIR IS TO BE PURIFIED AND/OR DETOXIFIED BY CATALYTIC OXIDATION IN AN INTEGRAL HEAT EXCHANGER AND REACTOR. THIS DEVICE OF A DOUBLE SPIRAL MADE BY WINDING TOGETHER TWO STRIPS OF METAL COATED WITH A CATALYST. ONE SPIRAL PASSAGE LEADS INTO THE CORE OF THE SPIRAL AND THE OTHER PASSAGE LEADS OUT. AN ELECTRICAL-RESISTANCE HEATER SUPPLIES ENERGY AT THE CORE OF THE SPIRAL. THE OUTFL ...
