Traffic signals may soon be smart enough to prevent car crashes. A team of scientists at Technion-Israel Institute of Technology in Haifa, Israel, is creating such signals by connecting computers and cameras to "stop" and "yield" signs.
When the cameras spot two cars approaching an intersection, the computer calculates the collision risk, then flashes warning lights on the sign to alert drivers to slow down or stop. The team's next goal is to invent a smart traffic light, which would delay a green light so an offending driver can clear an intersection without causing a crash. - Businessweek.com
London is equipped with 10,000 crime-fighting closed-circuit TV cameras - which cost approximately $400 million - but doubt has been cast on their ability to help solve crime, thanks to an analysis of the publicly funded camera network.
By comparing the number of cameras in each London borough with the proportion of crimes solved there, researchers found that police are no more likely to catch offenders in areas with hundreds of cameras than in those with hardly any. Four out of five of the boroughs with the most cameras have a below-average record of solving crime. - Thisislondon
Carnegie Mellon University professor Scott E. Fahlman said he was the first to use three keystrokes - a colon followed by a hyphen and a parenthesis - as a horizontal "smiley face" in a computer message 25 years ago.
Language experts say the smiley face and other emotional icons or emoticons, have given people a concise way in e-mail and other electronic messages of expressing sentiments that otherwise would be difficult to detect.
Fahlman posted the emoticon in a message to an online bulletin board at 11:44 a.m. on Sept. 19, 1982, during a discussion about the limits of online humor and how to denote light-hearted comments. - Yahoo.com
