The BSI-TOYOTA Collaboration Center has succeeded in developing a system which utilizes one of the fastest technologies in the world, controlling a wheelchair using brain waves in as little as 125 milliseconds. The new Toyota system fuses RIKEN’s blind signal separation and space-time-frequency filtering technology to allow brain-wave analysis in as little as 125 ms, as compared to several seconds required by conventional methods. Brain-wave analysis results are displayed on a panel so quickly that drivers do not sense any delay.The system has the capacity to adjust itself to the characteristics of each individual driver, and thereby is able to improve the efficiency with which it senses the driver’s commands.Thus the driver is able to get the system to learn his/her commands (forward/right/left) quickly and efficiently.

An Internet safety study (PDF) just released by Cox Communications shows that teens may be a bit more safety conscious than previously thought.
The survey, which was done by Harris Interactive, asked 655 13- to 18-year-olds about their online and cell phone behavior, specifically addressing issues of cyberbullying and sexting. The study was in partnership with the National Center for Missing & Exploited Children and "America’s Most Wanted Host" John Walsh.
For the purposes of the study, cyberbullying was defined as "harassment, embarrassment, or threats online or by text message," while sexting referred to "sending sexually suggestive text or e-mails with nude or nearly-nude photos."
Not surprisingly, the vast majority of teens (72 percent) have a social-networking profile, while 73 percent use cell phones and 91 percent have an e-mail address.
