Fire panels, or "annunciators," are electronic devices that display data on building conditions in one easily accessible location. When used by first responders during emergencies, the devices can save lives. In December 2005, the National Electrical Manufacturing Association (NEMA) released a comprehensive standard* that promises to make future annunciators even more useful decision-making tools to fire fighters at the scene, to commanders back at headquarters, or to building and emergency personnel rushing to a fire.
Developed with the help of the National Institute of Standards and Technology (NIST) and the U.S. fire alarm industry, the standard offers greater uniformity in design, operation and arrangement of fire panels, common symbols denoting fire-related building conditions, and equipment specifications concerning wireless and remote applications. The standardization effort should make real-time information of value clearly and quickly available for processing, planning and response. For instance, agreement on how to unambiguously represent conditions such as biochemical hazards or the locations of smoke vents and elevators should make the fire panels and related equipment much better tools for rapid decision-making. Similar display and message symbols also should save time and training funds currently needed to teach fire fighters to understand dissimilar fire panel systems. Finally, standardization is considered necessary for parallel efforts in the first responder community to develop a capability to transmit relevant, easy-to-understand building and fire emergency information to fire fighters prior to their arrival on the scene.
In a related development, NIST released proceedings of a July 26, 2005, workshop** held at its Gaithersburg, Md., campus in which fire safety personnel used laptops to simulate and to evaluate the usefulness of transmitting real-time fire panel data to dispatch centers and to officers at the scene monitoring fire fighters during an emergency. Participants considered four scenarios: (1) a hospital fire; (2) arson in a third-floor laboratory building room; (3) fire on the second floor of a two-story single family dwelling; and (4) an emergency medical call inside a large shopping mall. The final report lists almost 100 recommendations for improvements of current displays, ranging from suggestions for different colors for various fire conditions, better depiction of evacuation stairwell size, and even off-site screen printout capability.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
