MILITARY APPLICATIONS OF COMPUTER VISION SYSTEMS REQUIRE ORDERS OF MAGNITUDE IMPROVEMENT IN CAPACITY AND SPEED OVER CURRENT SYSTEM PERFORMANCE. THE PRINCIPLE OBSTACLES TO HIGHER PERFORMANCE ARE: THE LARGE AMOUNTS OF IMAGE DATA TO BE PROCESSED; IMAGERS UNOPTIMIZED FOR THE VISION TASKS (TARGET DETECTION, CLASSIFICATION, RECOGNITION, IDENTIFICATION AND TRACKING); AND OPEN-LOOP SYSTEM ARCHITECTURE. IN ...

DESIGN AND FABRICATION OF SOLID-STATE DIRECTION-INDICATING APPARATUS, WITH TILT-IMMUNITY, THAT PROVIDES AN AUDIBLE OR TACTILE INTERFACE WITH THE USER. REDUCED SIZE TO ALLOW ENCAPSULATION IN A TYPICAL WALKING CANE. A DEVICE WILL BE DESIGNED THAT WILL PROVIDE A VISUALLY IMPAIRED PERSON WITH AN INDICATION OF HORIZONTAL DIRECTION, WITH RESPECT TO THE EARTH'S MAGNETIC FIELD. THE DEVICE WILLALSO SIGNAL ...

N/A

SOLID-STATE LASER SYSTEMS HAVE BEEN IDENTIFIED AS A PARTICULARLY EFFECTIVE TRANSMITTER TECHNOLOGY FOR USE IN COHERENT LASER RADAR SYSTEMS, DUE TO THEIR NEAR-IR WAVELENGTH (1-2UM), COMPACTNESS, FREQUENCY AGILITY, AND EFFICIENCY. RECENT ADVANCES IN LASER DIODE ARRAY TECHNOLOGYHAVE OPENED NEW PROSPECTS FOR LONG LIFE, HIGH ENERGY AND AVERAGE POWER SOLID-STATE LASER RADAR INSTRUMENTS SUITABLE FOR EXTEN ...

N/A

SILICON CARBIDE (SIC) IS A SEMICONDUCTOR THAT POSSESSES A UNIQUE COMBINATION OF PHYSICAL AND ELECTRONIC PROPERTIES THAT MAKE DEVICES PRODUCED FROM THIS MATERIAL INTRINSICALLY RADIATION AND ELECTROMAGNETIC PULSE (EMP) RESISTANT. IN ADDITION, SIC DEVICES CAN OPERATE AT VERY HIGH TEMPERATURES AND FREQUENCIES AT HIGH POWER. RECENT RESEARCHON SIC HAS RESULTED IN THE FABRICATION OF METAL-OXIDE-SEMICONDU ...

BETA SILICON CARBIDE (B-SIC) POSSESSES A UNIQUE COMBINATION OF PROPERTIES IMPORTANT FOR APPLICATION IN HIGH FREQUENCY ELECTRONIC DEVICES CAPABLE OF OPERATING AT HIGH POWER. THE COMBINATION OF ITS WIDE BANDGAP, HIGH SATURATED ELECTRON DRIFT VELOCITY, HIGH BREAKDOWN ELECTRIC FIELD, LOW DIELECTRIC CONSTANT, AND HIGH THERMAL CONDUCTIVITYGIVE IT A FIGURE OF MERIT FOR HIGH POWER MICROWAVE APPLICATIONS T ...

N/A

THE NEED EXISTS FOR A METHOD TO CHARACTERIZE AND QUALIFY THE NECESSARY OFF-AXIS ASPERHICAL MIRROR TECHNOLOGY FOR USE IN WEAPON POINTING, BEAM CONTROL, AND BEAM PROPAGATION THROUGH SEVERAL ENVIRONMENTS AND COUNTERMEASURES. CURRENTLY, NO INSTRUMENT EXISTS THAT CAN MEASURE BOTH THE FULL SURFACE FIGURE AS WELL AS THE SURFACE ROUGHNESS. IN THIS INVESTIGATION, FEASIBILITY IS BEING DETERMINED OF A FULL-S ...

THE NONSPEAKING SUFFER FROM A LACK OF NATURAL-SOUNDING SYNTHETIC VOICES THAT ARE APPROPRIATE IN TERMS OF AGE, SEX, AND DIALECT. THE CREATION OF A WIDE RANGE OF NATURAL-SOUNDING VOICES HAS BEEN HAMPERED BY HIGH DEVELOPMENT COSTS RESULTING FROM A LACK OF ADEQUATE LINGUISTIC MODELS AND FLEXIBLE SOFTWARE TOOLS FOR TEXT-TO-SPEECH SYNTHESIS. ELOQUENT TECHNOLOGY, INC. (ETI) PROPOSES A NOVEL MODULAR APPRO ...
