Working principle:
Our patent product, electronic balanced anti-drowsy alarm, which is popularly called
nap-zapper, is a high-tech product that works on the principle of electronic balance.
It fits on the ear of a driver when he is drowsy or on a long trip. Once a
driver feels sleepy during his driving and his head nods forward, the alarm will
