Below is an Article from How Stuff Works about the anti sleep devices

The first type of alarm is built right into the car and uses sensors, cameras and other high-tech tricks to discern a driver's fatigue and correct the problem accordingly. The second type fits over the driver's ear and sounds an alert when the driver starts to fall asleep. While the in-car alarm systems are a recently developed feature that can add thousands of dollars to a car's sticker price, the over-the-ear alarm is both cheap and readily available. Drivers can find these for $10 to $20 under brand names like Nap Zapper, No Nap, and Doze Alert.

The names might sound funny, but the need for anti-sleep alarms is no joke. A poll conducted by the National Sleep Foundation showed that 60 percent of Americans have driven while feeling sleepy, and 37 percent admit to falling asleep at the wheel in the past year. In fact, sleepy driving can be deadly: The National Highway Traffic Safety Administration (NHTSA) reports that drowsy driving causes more than 100,000 car crashes -- and kills more than 1,500 people -- each year [source: Fenton]. While the safest course of action is to get a good night's sleep or to take a nap before driving, an anti-sleep alarm could come in handy on a late-night drive.

Sensing Driver Sleepiness

If you've ever fallen asleep on a subway train or in your high school algebra class, you know that your head tends to fall forward as you doze off. You also know that you may stay asleep for a few seconds or a couple of minutes before your head jerks upright and you're awake again. It's annoying on the bus commute home; it's downright dangerous when driving a car. The anti-sleep alarm looks for any indication that the driver's head is tipping forward: When the earpiece senses that the angle has increased from zero to, say, 15 or 30 degrees, it sounds an alarm. Most manufacturers stress that the sound is loud and irritating enough to wake the driver, but not so loud or sudden that he wakes up with a start and yanks on the wheel or steps harder on the gas.Let's start with the simplest anti-sleep alarm system, the over-the-ear gadget. This lightweight plastic device has an arm that slips over one ear, like some telephone earpieces or portable headphones do. Once it's on, a sensor inside the case measures the angle from a perpendicular perspective. If the driver is looking straight ahead -- as he or she should -- the alarm measures the angle at zero degrees.
