Nap Alarm with light

This is a doze alert device that helps prevent fatigue related automobile accidents.
It's wearing on the ear of a driver and works on the principle of electronic balance.
If you start to nod off while you are driving and your head falls forward,
the smart nap-zapper will buzz in your ear and help you avoid the danger of falling
asleep at the wheel. The alarm is not only designed to keep you woke until you
get where you are going, but to alert you to your drowsiness so that you can
take corrective actions. Change drivers, take a break (eat and drink) or take a
nap.

The alarm is about the size of an external hearing aid and weighs about 16g. It fits
snugly around one ear and will stay in place even when glasses are worn.

The alarm monitors the position of the driver's head. It gives out sound at the preset
angle. If the driver's head drops forward far enough, the alarm goes off. This position
at which the alarm will sound can be adjusted. For example, if your normal
driving posture is with eyes and chin pointed down, the device can be set to tolerate
that, but will sound off if the chin drops below a certain point. A gravity switch inside
the alarm monitors the angle of the driver's head.

Usually, drowsiness will sneak up on you unawares. Nap-zapper will assist you in
that area. Stay alert, stay alive, and nap-zapper.
