THREE SYSTEMS OF ACTIVE GUIDEWAY SWITCHING CONCEPTS ARE PROPOSED WHICH USE FAIL- SAFE ELECTRICAL SWITCHING WITHOUT NEED FOR LARGE MECHANICAL MOVEMENT OF GUIDEWAY STRUCTURAL MEMBERS. THE SPECIFIC APPLICATION OF THIS APPARATUS TO A 300 MPH, 40- 80 TONNE CLASS MAGLEV VEHICLE OF 50-200 PASSENGERS IS USED AS A BASELINE DESIGN WITH A VEHICLE WIDTH 3.65 M AND EXTENDING IN LENGTH FROM 14 M TO 56 M. THE TH ...

GUARDRAIL TERMINALS ARE SOME OF THE MORE TROUBLESOME AND POTENTIALLY HAZARDOUS ROADSIDE APPURTENANCES. RECENTLY DEVELOPED TERMINAL CONCEPTS WHICH HAVE PASSED CURRENT CRASH TEST CRITERIA TEND TO BE EXPENSIVE AND MAY REQUIRE EXCESSIVE LENGTH OF NEED, FLARE-OUT SPACE AND ADDITIONAL FILL AND GRADING. THIS PHASE I SBIR PROPOSAL ADDRESSES THE DEVELOPMENT OF A MORE EFFICIENT ENERGY ABSORBING TERMINAL CON ...

SOUTHWEST SCIENCIES, INC. PROPOSES A NOVEL MASS SPECTROMETRIC METHOD, * IONIZATION ENERGY MODULATED MASS SPECTROMETRY (IEMMS), FOR THE RAPID DETECTION OF VAPORS FROM EXPLOSIVES, INCENDIARIES AND NOXIOUS GASES. IEMMS COMBINES ELECTRON IMPACT IONIZATION USING A MONOCHROMATIC ELECTRON BEAM WITH ION DETECTION USING TWIN TIME-OF-FLIGHT (TOF) MASS ANALYZERS. ONE ANALYZER QUANTIFIES POSITIVE IONS WHILE T ...

SEVERAL CONCEPTS ARE PROPOSED FOR LOCOMOTIVE CAB ALERTERS THAT CAN BE RETROFITTED TO ALERTER SYSTEMS ALREADY IN SERVICE. THE CONCEPTS INCLUDE A TOUCH SCREEN, WHICH REQUIRES TOUCHING A TARGET TO RESET THE TIMER OR TO RESPOND TO THE ALERTER LIGHT PROMPT. THE INITIAL LOCATION OF THE TARGET ON THE SCREEN IS AUTOMATICALLY SELECTED AT RANDOM. ANOTHER CONCEPT IS THE USE OF A TELEPHONE KEYPAD WITH LCD, WH ...

Searching for street parking, a behavior known as cruising for parking, leads to excess congestion and pollution. Many recent smart parking interventions have attempted to address this issue, but the problem of effectively detecting and measuring cruising remains largely unsolved. The goal of this work is to develop methods to detect and measure cruising for parking and its effects on congestion u ...

THE PURPOSE OF THIS RESEARCH PROJECT IS TO DETERMINE THE FEASIBILITY OF MERGING AN EMERGENCY MEDICAL SERVICES (EMS) SIMULATOR WITH GEOGRAPHICAL INFORMATION SYSTEMS (GIS) IN ORDER TO PRODUCE IEMS(3) (INTELLIGENT EMERGENCY MEDICAL SERVICES SYSTEMS SIMULATOR), A PC-BASED SYSTEM WHICH CAN BE USED FOR BOTH ADDRESSING STRATEGIC PLANNING ISSUES OF EMS SYSTEMS (E.G., SYSTEM CONFIGURATION; VEHICLE LOCATION ...

PRESENT DAY FIRE DETECTORS NORMALLY EMPLOY A SINGLE SENSOR, SUCH AS AN OPTICAL DENSITY OR IONIZATION DETECTOR, THAT HAS WELL KNOWN LIMITATIONS. ALARM DECISIONS ARE THUS BASED ON A SINGLE MEASUREMENT THAT IS OFTEN INACCURATE, AND INSENSITIVE. WE PROPOSE TO USE AN ARRAY OF VERY SMALL AND INEXPENSIVE SOLID-STATE DEVICES THAT ARE HIGHLY SENSITIVE TO A VARIETY OF PHYSICAL EFFECTS AND CHEMICAL VAPOR PRO ...

THE PROPOSED RESEARCH ADDRESSES A NEED FOR A WORKABLE METHODOLOGY FOR RECORDING THE ENERGY FORCES FROM DIRECT AND SLIDING (ABRASION) CONTACTS ON ANTHROPOMORPHIC DEVICES WITHIN THE INTERIOR OF A VEHICLE ON IMPACT. THE SCOPE OF THIS PROPOSAL IS TO DETERMINE FEASIBILITY OF INCORPORATING CALIBRATED PRESSURE SENSITIVE MICROENCAPSULATED DYE (MED) SENSORS INTO A COATING THAT ADHERES TO ANTHROPOMORPHIC CR ...

ECOTEK INTERNATIONAL PROPOSES AN ALL SOLID-STATE VISIBILITY MONITORING SYSETM THAT WILL BE USED TO MONITOR VISIBILITY CONDITIONS ALONG ROADWAYS AND WARN TRAVELERS OF LOW VISIBILITY CONDITIONS. THE PURPOSE OF THE SYSTEM IS TO REDUCE THE NUMBER OF MULTIPLE-VEHICLE COLLISIONS AND CONSEQUENT FATALITIES, INJURIES, AND PROPERTY DAMAGES. THE SYSTEM IS BASED ON AN INNOVATIVE APPROACH TO A WELL-ESTABLISHED ...
