THE PURPOSE OF THIS EFFORT IS TO DETERMINE THE FEASIBILITY AND UTILITY OF A MICROCOMPUTER-BASED SERIES OF NEUROPSYCHOLOGICAL TESTS THAT INCORPORATE VISUAL, AUDITORY, AND MOTOR SKILLS. THE OBJECTIVE IS TO DEVELOP A MICROPROCESSOR HARDWARE SYSTEM THAT: 1.IS RELATIVELY INEXPENSIVE (UNDER $10,000); 2.IS FOUND PLEASANT AND SATISFYING TO INTERACT WITH BY THE PATIENT;3.CAN GENERATE MULTISENSORY STIMULI ( ...

A COMPACT, PLANETARY GEAR TRANSMISSION DESIGN WITH LOW WEIGHT-TO-HORSEPOWER RATIO MADE POSSIBLE THROUGH HIGH ENERGY CLUTCH ASSEMBLIES, HAS LOW IMPEDANCE FLOW CHANNELS WHICH FACILITATE RAPID CIRCULATION OF COOLING FLUID TO TRANSPORT HEAT AWAY FROM FRICTION SURFACES. SURROUNDING THE CLUTCH ASSEMBLIES IS A HEAT EXCHANGER TO TRANSFER HEAT DIRECTLY TO THE ATMOSPHERE. DURING OPERATION OF THE CLUTCHES, H ...

THE OVERALL OBJECTIVE IS TO DEVELOP IMPROVED COMPOSITE FILLING MATERIALS SUITABLE FOR RESTORING POSTERIOR TEETH AS WELL AS ANTERIOR. THE GOAL IS PERMANENCE. TWO PRIMARY OBJECTIVES ARE TO INCREASE THE CONCENTRATION OF FILLER TO 90% BY WEIGHT AND TO MAXIMIZE THE ADHESION BETWEEN THE RESIN AND FILLER. THE APPROACH ENTAILS COATING EACH FILLER PARTICLE WITH A THIN FILM OF POLYMER IN SUCH A WAY THAT OPT ...

FLUME TESTS OF THE SCOUR-RESISTANT PROPERTIES OF A COMPOSITE SCOURINHIBITING MATERIAL ARE PROPOSED. THE MATERIAL IS MADE FROM GRAVEL AND CLAY. BY FILLING THE PORE SPACES IN THE GRAVEL, THE CLAY PREVENTS TURBULENT FLUID BURSTS FROM PENETRATING THE GRAVEL AND "SUCKING OUT" UNDERLYING BED MATERIAL. THE SCOUR INHIBITOR REMAINS PLASTIC AND FORMS A GRADATIONAL MARGIN BETWEEN ANY RIGID STRUCTURE AND A MO ...

THE PRESENT ROCKET MOTOR LINER SYSTEMS, USUALLY MADE FROM THE SAME POLYMERIC MATERIALS, USED AS THE BINDER IN THE SOLID PROPELLANTS ARE PERMEABLE TO MOISTURE VAPOR AND TO THE RESIDUAL ORGANIC LIQUIDS AND CORROSIVE CHEMICAL FROM THE SOLID PROPELLANT. THE PROPOSED PROGRAM WILL TRY TO DECREASE THIS PERMABILITY BY INVESTIGATING COMPOSITES OF KNOWN BARRIER FILM BETWEEN THE LINER MATERIALS. WE ALSO INTE ...

THE LONG-TERM OBJECTIVE IS TO DEVELOP A SYNTHETIC PERICARDIUM FOR USE FOLLOWING OPEN HEART SURGICAL PROCEDURES, PARTICULARLY INVOLVING CARDIOPULMONARY BYPASS AND THE USE OF A TOTAL ARTIFICIAL HEART AS A BRIDGE TO TRANSPLANTATION. THE APPROACH UTILIZES A NEW CLASS OF BIOMATERIALS, ELASTOMERIC POLYPEPTIDES, THAT CAN BE CROSS-LINKED TO FORM BIOCOMPATIBLE, ELASTOMERIC MATRICES. THE METHODOLOGIES INVOL ...

N/A

DEVELOPMENT AND DELIVERY OF A DIRECT REPLACEMENT OPTICAL STORAGE DEVICE FOR THE AN-USH-24 14/28 TRACK MAGNETIC TAPE DATA RECORDER. OPTICAL STORAGE DEVICE WILL EMPLOY W.O.R.M. (WRITE ONCE READ MULTIPLE) TECHNOLOGY WITH "STATE OF THE ART" HIGH SPEED ELECTRONIC PERIPHERY HOSTED BY AN 80386 MICROPROCESSOR. UNIT WILL READ AND RECORD DATA ON 5 1/4" REMOVABLE OPTIC DISKS. EACH DISK WILL BE CAPABLE OF STO ...

THE PRESENT RESEARCH IS DESIGNED TO IMPROVE LONG WEAR CONTACT LENSES SO THAT WEARING OF SUCH LENSES WILL NOT EFFECT THE CORNEA AND TO REDUCE EYE DISEASE CAUSED BY WEARING OF CONTACT LENSES. A LENS WILL BE PRODUCED THAT IS HIGHLY OXYGEN PERMEABLE AND YET HAS A SURFACE THAT IS WETTABLE AND RESISTANT TO DEPOSITS. A CORE OF PURE SILICONE WITH A ULTRATHIN PLASMA POLYMER SURFACE WILL BE USED. SILICONE W ...
