A new device from Smarthome, the Drive Alert Master, offers an alternative to caffeine, loud music, and rumble strips to keep to keep drivers from falling asleep at the wheel. Attach the Drive Alert Master to your ear, and at the first sign of driver drowsiness, it jolts you back to wakefulness.

The device works with motion detectors, which are adjustable from 15 to 30 degrees. When you start nodding, the device sets off a loud beep, which doesn't stop until your head is back in an upright position. The Drive Alert Master has extra padding to make it more comfortable during those endless road trips. It sells for for $14.99, with a 1.5 volt battery included.
