Investor’s Business Daily - Scientists at two Finnish universities have developed a smart alarm clock for certain Nokia cell phones that’s available for download at happywakeup.com. The alarm clock is smart because in the 20 minutes before the alarm time, it listens for sounds indicating that the user is almost awake due to natural sleep rhythms. During those moments, waking up is easier. When the clock detects one of those almost-awake moments, it sounds a soft alarm.
