More than 52% of U.S. urban highway congestion is a direct result of highway incidents. Federal and State transportation authorities are searching for quick, cost-effective and efficient highway incident detection and warning systems. Several solutions have been proposed but none could satisfy requirements of transportation authorities. Central Signal's research and development, grounded in mor ...

Mechanical damage (typically from third party excavations) is the most frequent source of leaks and ruptures in pipelines. The most common type of mechanical damage is dents, sometimes associated with secondary features such as gouges, external corrosion, or cracks. Currently used techniques for assessing dents are not accurate enough for reliable determination of fitness for service. In this p ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...

PACIFIC-SIERRA RESEARCH PROPOSES TO DEVELOP A NOVEL SENSOR MODULE FOR COUNTING VEHICLE AXLES ON ROADWAYS. THIS SENSOR WOULD NOT REQUIRE ANY MODIFICATIONS TO THE ROADBED, AND COULD BE SAFELY SETUP WITHOUT IMPEDING TRAFFIC EVEN TEMPORARILY. THE SENSOR WILL DETECT THE AXLES ON MULTIPLE LANE HIGHWAYS AND KEEP THE SEPARATE LANE COUNTS DISTINCT. THIS ROADWAY LAND AXLE DETECTOR (LAD) IS BASED ON EXISTING ...

Anti-glare visors and rearview mirrors for cars can be constructed by inserting a photochromic layer in the focal plane of an optical system. Rays from intense glare souces are focused and create dark spots on the photochromic layer and thus self attenuate. Rays from dim objects are left unaffected. The optics can be achieved with either conventional lenses or microlens arrays. Anti-glare devi ...

Extensive research (Ukraine) has shown that high strength continuous fibers of basalt can be produced. These fibers are inexpensive and have exceptionally high strength, stiffness and corrosion resistance. Basalt is a naturally occurring volcanic mineral, consisting a variety concentration of oxides. The product envisioned is a low-cost, corrosion resistant replacement for steel bar in reinforc ...
