THE IDENTIFICATION OF THE TYPE OF PRECIPITATION (RAIN, SNOW, FOG/HAZE, HAIL) HAS TRACTIONALLY RELIED ON HUMAN JUDGMENT. RECENTLY, THE WAVE PROPAGATION LABORATORY OF DEVELOPED A TECHNOLOGY FOR AUTOMATIC WEATHER IDENTIFICATION USING LASER SCINTILLATION AND SCATTERING. THE TECHNIQUE HAS BEEN SUCCESSFULLY TESTED IN FIELD OPERATION. HOWEVER, THE SYSTEM IS TOO CLUMSY AND EXPENSIVE FOR LARGE-SCALE FIELD ...

THE MEASUREMENT OF THE RETROREFLECTIVITY OF PAVEMENT MARKINGS OR TRAFFIC STRIPING HAS BEEN LIMITED BY THE INSTRUMENTATION AT PRESENT. THE MAJORITY OF THESE INSTRU- MENTS ARE HAND-HELD PORTABLE UNITS WITH LIMITED GEOMETRY ANDNEASUREMENT AREA. MOBLE UNITS BUILT BY SOME STATES ALSO ARE LIMITED IN THEIR PERFORMANCE BY STRAY LIGHT, NON-OPTIMUM GEOMETRY AND OTHER PROBLEMS. A NEW RETROREFLECTOMETER IS PR ...

THE USE OF THERMAL NEUTRONS AS A TOOL FOR BAGGAGE INSPECTIONIS AN ESTABLISHED TECHNIQUE, WITH A PROTOTYPE SYSTEM CURRENTLY BEING TESTED FOR AIRPORT FEASIBILITY AS AN EXPLOSIVE DETECTION DEVICE. THIS SYSTEM COULD POSSIBLY BE MODIFIED FOR INDIVIDUAL BAGGAGE IDENTIFICATION THROUGH THE USE OF IMAGING OR ACTIVATION DETECTION OF SUITABLE TAGS. HOWEVER, FEASIBILITY TESTING OF THIS CONCEPT AND THE COMMERC ...

WITHIN THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION THERE IS A SIGNIFICANT NEED TO PROVIDE ACCIDENT INVESTIGATORS WITH ADVANCED COMPUTER BASED TOOLS THAT CAN ASSIST IN THE ANALYSIS OF ACCIDENT DATA. IN PARTICULAR, AN "EXPERT SYSTEM" THAT COULD INTERPRET THE VARIOUS SOURCES OF ACCIDENT DATA AND AUTOMATICALLY CODE THESE IN ACCORDANCE WITH VARIOUS INJURY CODING SCHEMES, WOULD BE OF SIGNIFICANT ...

THE SUCCESS OF PREVIOUS CONVENTIONAL NUCLEAR MAGNETIC RESONANCE (NMR) AND NUCLEAR QUADRUPOLE RESONANCE (NQR) SYSTEMS FOR DETECTING EXPLOSIVES IN AIRLINE BAGGAGE HAS BEEN LIMITED BY THE NEED TO OPERATE AT LOW FIELDS AND LOW FREQUENCIES WHERE THE SENSITIVITY OF SUCH SYSTEMS IS SEVERELY LIMITED. HOWEVER, RECENT EXPERIMENTS HAVE SHOWN THAT SUPERCONDUCTING DEVICES IN NMR DETECTION CIRCUITS CAN ACHIEVE ...

TO THE EXTENT THAT THE ADVENT OF COMPUTERIZED AIR TRAFFIC CONTROL SYSTEMS NEEDS AN EFFECTIVE MAN-MACHINE DIALOGUE WHICH IS NOT ENCUMBERED BY EXCESSIVE KEYBOARD INTERACTION, A REAL-TIME CONTINUOUS SPEECH INTERFACE CAN SOLVE THIS PROBLEM. UNTIL NOW, SPEECH-RECOGNITION TECHNOLOGIES HAVE BEEN CHARACTERIZED BY LIMITED VOCABULARY, RESTRICTED SYNTAX, AND WORD ISOLATION. THIS STUDY WILL DEMONSTRATE THE FE ...

PRESENT TRAIN DETECTION SCHEMES RELY LARGELY ON A LOW RESISTANCE THROUGH THE TRAIN'S WHEELS TO PERTURBATE A STABLE ELECTRICAL CIRCUIT. WHILE ELEGANT IN PRINCIPLE, THE DESIGN IS PLAGUED BY OXIDE FILMS AND MATERIAL BUILDUP ON THE RAIL, SNEAK PATHS THROUGH THE BALLAST AND OTHER UNCONTROLLABLE VARIABLES. KVH INDUSTRIES PROPOSES TO DESIGN AND DELIVER A "SMART MAGNETOMETER"-BASED SENSOR PACKAGE WHICH WI ...

On average, a pedestrian is killed every 2 hours and injured every 8 minutes in traffic crashes. 73% of these fatalities occur in urban areas. The SmartCross system aims to reduce the risk of vehicle-pedestrian crashes by providing situational awareness to the pedestrian as well as the vehicle approaching a crosswalk. The system makes use of the proliferation of smartphones to provide audio, visua ...
