TLK ® SAFE DEVICE ANTI SLEEP ALARM
It works on the principle of electronic balance and does not interfere with normal movements in the car. The alarm sounds only when the driver's head falls forward in drowsiness, simple but effective. The alarm will sound at the preset angle. If the driver's head drops forward far enough, the alarm sounds off. This position at which the alarm will sound can be adjusted. A gravity switch inside the alarm monitors the position of the driver's head. It is about the size of an external hearing aid and is lightweight. It fits snug around one ear and will stay in place even if glasses are worn.
