I distinctly remember the headband trend of the 70s and 80s.  Although I didn’t think it would come back, I was dismayed to see its return some years ago.  Guess what? Looks like there’s a newer version of it and it is pretty hi-tech.  The Impecca Alert Band is placed across your forehead and promises to keep you informed should you start dozing off while driving.  The headset is a wearable EEG, meaning that it is monitoring your brain for signs of fatigue in real-time.  In fact, it can detect you falling asleep minutes before it happens and once it does, it wirelessly notifies your cell phone to set off an alarm. The Impecca Alert Band has a 20 hour battery life and is set to hit the market this spring for $249.99.
