INDUCTIVE LOOPS HAVE BEEN USED IN RAODWAYS FOR VEHICLE SURVEILLANCE AND TRAFFIC CONTROL SYSTEMS SINCE THE LATE 1960'S. THESE EARLY SYSTEMS WERE PLAGUED WITH DRIFT AND ENVIRNMENTAL CHANGE PROBLEMS WHICH RESULTED IN UNRELIABLE OPERATION AND FREQUENT MAINTENANCE. MODERN LOOP SYSTEMS, AFTER TWO DECADES OF IMPROVEMENTS, HAVE BECOME HIGHLY DEPENDABLE AND REMAIN VIRTUALLY TROUBLE-FREE AFTER YEARS OF SERV ...

THIS PROJECT WILL DEMONSTRATE THE FEASIBILITY OF A MULTI-ZONED LINE FIRE DETECTION SYSTEM FOR AIRCRAFT. THIS WILL INCLUDE INTEGRATING THIS SYSTEM WITH A MICROPROCESSOR TO CONTROL, INTERPRET AND ANNUNCIATE THE FIRE ALARM SIGNALS.IN THIS WAY THE MULTI-ZONED DETECTION AND COMPUTER CONTROL WILL PROVIDE THE CAPABILITY TO MONITOR AND DISPLAY THE GROWTH AND SPREAD OF A FIRE IN REAL-TIME.

THE PROPOSED METHOD OF DETECTION OF CONCEALED WEAPONS IS SPECIFICALLY DIRECTED TOWARD NONMETALLIC WEAPONS (HANDGUNS AND EXPLOSIVES) CARRIED UNDER THE CLOTHING OF PEOPLE. THE METHOD IS PROPRIETARY, BUT IT CAN BE SAID HERE THAT IT IS NONCONTACTING AND NONOBTRUSIVE. THE SEARCH MAY TAKE PLACE WITH THE SUBJECT NOT BEING AWARE OF THE ACTION OF THE SENSOR. THE SENSOR IS PASSIVE AND DOES NOT MAKE USE OF A ...

A PROGRAMMABLE DEFECT SIMULATOR IS NEEDED TO TEST ULTRASONIC RAIL FLAW DETECTION SYSTEMS. CALIBRATION STANDARDS CAN BE DEVELOPED WITH VARIABLE PHYSICAL CHARACTERISTICS ACCORDING TO A PREDESCRIBED SCHEME THAT SIMULATES COMMONLY-OCCURRING FLAWS (CROSS-HEAD FATIGUE CRACKS) IN RAILWAY SYSTEM RAILS. THIS PROJECT WOULD DEVELOP A METHOD OF ALTERING THE EFFECTIVE REFLECTIVITY OF A SOLID-GAS INTERFACE THRO ...

Portable tanks used to transport hazard materials are often subject to forces and stress, thermal cycle loading, and shock/vibration throughout the transportation process. It is an interest to assess what effects may occur during loading and unloading from one shipping mode to another and what conditions the HM packages will experience in that specific mode. An in-situ sensor system is proposed he ...

Intelligent Automation Inc. (IAI) proposes an innovative anti-texting system which does not prevent the use of any cell phone but can detect and record the texting and driving behavior for enforcement instead. This proposal lays out a concrete plan to develop a robust and cost effective system that can detect, identify and record the instances when a driver is texting (or voice calling without ha ...

Usually the lifetime of a trailer is much longer than tractors; tractors must work with a variety types and ages of trailers over the course of their use. In many scenarios (e.g., roadside, border crossing, smart parking, connected vehicle initiative, etc.), it is necessary to identify trailer(s)' VIN(s) and know their order attached to the powered unit. An automated trailer VIN identification and ...

A method to detect, locate, and map utilities and underground infrastructure is proposed at traffic speeds based on recent advances in step-frequency ground penetrating radar (SFGPR). Recent work by the proposed research team has already demonstrated imaging of subsurface civil infrastructure elements such as pavement structure and inductive loop detectors embedded in the pavement. The proposed r ...

Intelligent Automation Inc (IAI) in collaboration with IDS North America proposes to develop the next generation Ground Penetration Radar (GPR) technology called GeoRad. We will leverage an existing state –of-the-art dual-frequency dual-polarized massive array GPR and improve its accuracy so that wires, and pipes can be mapped. The accuracy of the position of the ground penetration radar directl ...
