USCG SOLICITATION 90-CG5 SUGGESTS EVALUATION OF KALMAN FILTERING A DIGITAL SIGNAL PROCESSING (DSP) TECHNIQUE, TO IMPROVE GEODETIC POSITIONING PROVIDED BY SINGLE CHAIN, AND EVENTUALLY, MULTICHAIN LORAN RECEIVERS. A DSP TECHNIQUE COMPARABLE TO KALMAN FILTERING HAS ALREADY BEEN IMPLEMENTED ON A SINGLE CHAIN LORAN RECEIVER, RESULTING IN SUBSTANTIAL GEODETIC POSITIONING IMPROVEMENTS IN NOISY, DYNAMIC E ...

THIS PROJECT IS DESIGNED TO FURNISH FHWA WITH A NUMBER OF IMPORTANT PRODUCTS IN PREPARATION FOR ACCELERATED LIFE TESTING (ALT) OF A LARGE SCALE MODEL JOINT AND A LONG TERM FULL SCALE BEAM TEST TO VERIFY THE ALT. THE MOST IMPORTANT PRODUCT IS A PROCEDURE FOR INTRODUCING DESIRED MOISTURE LEVELS INTO LARGE AREA BONDS IN A RELATIVELY SHORT TIME. A SECOND PRODUCT IS THE ALT PLAN WHICH ACCOUNTS FOR THE ...

THE PROPOSED PROGRAM PRESENTS A PLAN TO DEVELOP THE PRELIMINARY DESIGN OF A SECONDARY THERMOELECTRIC POWER PLAN THAT CAN BE USED IN THE COAST GUARD'S MAJOR AIDS TO NAVIGATION. THIS DESIGN WILL TAKE THE SPECIFIC NEEDS OF THE COAST GUARD INTO CONSIDERATION. THIS INCLUDES POWER LEVEL, SIZE, COST, AND RELIABILITY GOALS. THE DESIGN WILL USE AS MUCH OF THE TECHNOLOGY RELATED TO POWER SYSTEMS OF THIS TYP ...

UNCONTAINED AIRCRAFT TURBINE ENGINE FAILURES ARE DISASTEROUS. CURRENT EFFECTIVE NDE TECHNOLOGIES ARE CONSTRAINED TO UNSTRESSED, PART-LEVEL INSPECTION WHICH MAY NOT DETECT AN INCIPIENT FAILURE. USING APPROPRIATE ASPECTS OF COMPUTED-TOMOGRAPHY (CT) TECHNOLOGY, WE PROPOSE TO DEVELOP A SPIN-SYNCHRONOUS X-RAY SINOGRAPHY SYSTEM (SXS) THAT WILL BE CAPABLE OF DETECTING INCIPIENT FLAWS IN OPERATING TURBINE ...

UNTIL NOW, PRECISION, LABORATORY QUALITY, AUTOMATED CONTROL OF REMOTE VEHICLES HAS BEEN UNAVAILABLE. THERE EXISTS A NEED FOR PRECISE, REPEATABLE, AUTOMATED CONTROL OF TEST VEHICLES FOR IMPORTANT AND EXPENSIVE VEHICLE COLLISION TESTING. BY APPLYING OUR PROPRIETARY NEW TECHNOLOGY, SUCH VEHICLE CONTROL IS POSSIBLE. THIS TECHNOLOGY IS BASED ON AFFORDABLE COMPUTER BASED LOCAL NAVIGATION AND ROBOTIC CON ...

A KEY FACTOR IN THE ABILITY TO SAFELY OPERATE A TRAIN IS THEOPERATOR ALERTNESS. OPERATOR ALERTNESS CAN BE COMPROMISED AS A RESULT OF FATIGUE, SUBSTANCE ABUSE OR EMOTIONAL DISTRESS. A DEVICE THAT WOULD OBJECTIVELY REPORT A PERSONS STATE OF ALERTNESS COULD INDICATE THAT PERSONS FITNESS FOR DUTY, FOR EXAMPLE, AT THE BEGINNING OF A SHIFT. IT IS WELL KNOWN THAT ALERTNESS IS HIGHLY CORRELATED WITH VARIO ...

AN INNOVATIVE LOW POWER DIGITAL COMMUNICATION (LPDC) SYSTEM IS PROPOSED WHICH WILL ENCODE RAW DATA FROM THE SELF POWEREDVEHICLE DETECTORS (SPVD) SENSORS AND SEND ENCODED DATA TO THE RECEIVED BASE STATION VIA THE LPDC DEVICES. THE PROPOSED ENCODING ALGORITHM WILL ALLOW THE LPDC TO OPERATE RELIABLY IN THE PRESENCE OF INTERFERENCE FROM OTHER COMMUNICATION USERS. PRELIMINARY ANALYSIS SHOWS THAT BY UTI ...

THIS PROPOSAL DESCRIBES AN INNOVATIVE FILTERING TECHNIQUE THAT CAN BE USED TO DETECT AND REJECT OUT-OF-TOLERANCE MEASUREMENTS FROM A DIFFERENTIAL GPS NAVIGATION SOLUTION. THE TECHNIQUE CAN BE APPLIED FOR BOTH MOBILE AND STATIC APPLICATIONS AND COULD BE INTEGRATED INTO SHIPBOARD OR REFERENCE STATION GPS RECEIVERS. USING THE FILTER DESIGN PROPOSED, ERRORS CAUSED BY MULTIPATH, SATELLITE, RECEIVER ORR ...

CANS WILL BURST FROM OVER-PRESSURIZATION AS A RESULT OF THE AEROSOL CAN IS A CONSUMER CONVENIENCE ITEM USED FOR MANYYEARS. HOWEVER, SAFETY PROBLEMS HAVE EXISTED BECAUSE THE CANS WILL BURST FROM OVER-PRESSURIZATION AS A RESULT OF OVER-TEMPERATURE. THE PROBLEM IS MADE ACUTE BY THE INTRODUCTION OF FLAMMABLE PROPELLANTS AND SERIOUS CONCERNS EXIST FOR SAFE TRANSPORT OF THESE CANS IN AIRCRAFT CARGO COMP ...

WE PROPOSE A RESEARCH AND DEVELOPMENT PROGRAM TO DESIGN A LASER RADAR SYSTEM FOR MEASURING ROADSIDE ENCROACHMENT. A SEQUENCE OF LASER PULSES IS USED TO DETERMINE THE VEHICLE'S VELOCITY, AN X-Y POSITION MAP, AND THE DISTANCE FROM THE MEASUREMENT SYSTEM. THE ROADSIDE ENCROACHMENT POSITION IS DETERMINED FROM THE X-Y MAP OF THE VEHICLE'S LOCATION. THISMAP ALSO INCLUDES INFORMATION ON THE VEHICLE SHAPE ...
