THE GOAL OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF DEVELOPING A GENERAL PURPOSE TACTILE SENSOR CAPABLE OF IDENTIFYING THE TEXTURE, COMPLIANCE, AND SURFACE FEATURES OF AN OBJECT. THE TACTILE SENSOR WILL CONSIST OF A PIEZOELECTRIC POLYMER MATERIAL WHICH GENERATES AN ELECTRICAL SIGNAL IN RESPONSE TO AN APPLIED FORCE. THE SENSOR WILL BE DESIGNED TO MOVE ACROSS THE OBJECT BEING EXAMINED, AND T ...

FERRIMAGNETIC OXIDES WITH HEXAGONAL CRYSTAL STRUCTURE ARE CHARACTERIZED PRIMARILY BY THEIR FOLIATE (LEAF-LIKE OR PLATELET) STRUCTURE AND HIGH ANISOTROPY FIELDS. THESE HIGHLY ANISOTROPIC COMPOUNDS CAN BE PREPARED AS A COMPOSITE COMPOSED OF SINGLE DOMAIN GRAINS POSSESS ING A SPECTRUM OF CONTROLLED VALUES OF ANISOTROPY FIELDS AND ATTENDANT PREFERRED DIRECTION OF MAGNETIZATION. THESE HEXAGOAL SINGLE D ...

THE RESEARCH IS FOCUSED ON EVALUATING THE FEASIBILITY OF USING A NOVEL ELECTROFORMING PROCESS TO PRODUCE LOW LOSS FERRITE COMPONENTS FOR APPLICATION IN THE EHF REGION. THE PROPOSED PROCESS HAS POTENTIAL FOR REDUCING CONDUCTION LOSS AND IMPROVING DIMENSIONAL CONTROL. ADDITIONAL BENEFITS REGARDING CONFIGURATION AND RELIABILITY ARE ANTICIPATED.

RELIABLE THROUGH-THE-EARTH COMMUNICATIONS (TEC) ARE NEEDED FOR COMMAND AND CONTROL OF DEEP-BASED ICBM SITES. THE REQUIRED DATA RATES CAN BE ACHIEVED BY USING BOTH SIGNAL CODING AND SIGNAL-TONOISE-RATIO (SNR) ENHANCEMENT TECHNIQUES. THE KEY SIGNAL-PROCESSING ELEMENTS OFJSUCHASYSTEM ARE: NOLINEAR PROCESSING (NLP), ADAPTIVE NOISE CANCELLATION (ANC), QUADRATURE-AMPLITUDE MOUDLATION (QAM), ERROR-CORREC ...

RECENT ADVANCES IN MICROCOMPUTER TECHNOLOGY HAVE MADE IT POSSIBLE FOR VISUALLY IMPAIRED PERSONS TO CONTINUE NORMALLY WITH THEIR EDUCATION. VOICE SYNTHESIZERS AND TEXT MAGNIFI CATION ENABLE HANDICAPPED INDIVIDUALS TO BEAR RO READ BOOKS,MAGAZINES, AND OTHER PUBLICATIONS WHICH ARE STORED IN D N DIGITAL FROM IN THE MICROCOMPUTER. THE RECENT INTRODUCTION OF A LOW COST, MANUALLY OPERATED, OPTICAL SCANNE ...

THE PURPOSE OF THIS PROJECT IS TO DETERMINE WHETHER NEWLY AVAILABLE ROBOT TECHNOLOGY CAN BE USED TO FACILITATE THE SELF-SUFFICIENCY OF ELDERLY INDIVIDUALS LIVING AT HOME. TWO ""PERSONAL HEALTH AND SECURITY ROBOT'' (PHASER) UNITS ARE BEING CONSTRUCTED USING STATE-OF-THE-ART SENSORS, A VOICE SYNTHESIS AND RECOGNITION SYSTEM, A ROBOT ARM, AN OMNIDIRECTIONAL BASE, AND ENHANCED COMPUTER PROGRAMMING. TH ...

DYSLEXIA AFFECTS MILLIONS OF CHILDREN AND ADULTS. THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP, TEST, AND MARKET SOFTWARE DESIGNED TO REMEDIATE DYSLEXIA. NO SUCH PRODUCT CURRENTLY EXISTS. DURING PHASE I, A PROTOTYPE READING PROGRAM WILL BE PRODUCED BASED ON INSTRUCTIONAL CONTENT SPECIFIED WITH CONSULTANTS MARION BLANK AND ISABELLE LIBERMAN, BOTH WELL-KNOWN RESEARCHERS IN THE PROCESSES INVOLVED IN R ...
