Researchers at the National Institute of Standards and Technology (NIST) are assisting the Department of Transportation (DOT) by developing tests for a crash avoidance system that could substantially reduce the number of rear-end, road departure and lane change accidents. About 1,836,000 such accidents occur annually, or 48 percent of police-reported cases a year.
DOTs "Integrated Vehicle-Based Safety System" (IVBSS) for light vehicles and trucks is a single crash avoidance system under development that combines technologies used in separate warning systems. It is intended to simultaneously detect and warn drivers of any of three different forms of crashes at different speeds and in specified driving situations. The integration of individual systems is expected to increase safety benefits, improve overall system performance, reduce system cost, and enhance consumer and fleet acceptance.
NIST has designed preliminary test procedures that address DOTs needs. An IVBSS developer, under contract with DOT, will use the NIST tests to measure the performance of the safety system, as well as its components, such as sensors and warning algorithms. NIST-derived performance tests will include ways to determine the systems ability (1) to warn drivers of possible collisions between the front of their vehicles and the rear of a stationary lead vehicle or decelerating vehicle; (2) to detect a moving vehicle in adjacent lanes and the host cars drift toward them, (3) to identify the presence of parked cars, guardrails or other roadside objects and determine the available maneuvering room.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
