TWS is the tiredness early warning system for driver against fatigue and drowsiness. TWS is developed by Elong Tech and based on the 7 years of scientific research by the efforts of couple of experts. On the biology theory, scientists integrated many processors into the tiny smart TWS to monitor the signals from human body. The processing units include special type of alloy sensors, data collectors, CPU (Central Processing Unit), alarm, digital display. By processing these signals, the system sends timely and accurate warning and alert information to the driver against the signs of fatigue and drowsiness through visual, acoustical and haptic method.
