IV. Functional process
Two seconds after power is turned on, the green light will flash. At
night the red infrared LED can also be seen. After 30 seconds, the
system goes into the active state. The green light means your eyes are
open, the light is off when your eyes closed, or not in view. When it is
first installed, you adjust the position according to green light.
The EA401 will remind the driver before entering a dangerous driving
status. The human retina will become less and less sensitive to the
light outside, the artificial intelligence software inside the system is
detecting the status continuously, and it will give an audible alarm to
remind the driver take a rest.
The EA401 can also detect a distracted driver, such as talking with
back-seat passengers, adjusting dashboard controls, reading, texting,
picking up items on the floor, and give audible reminders to prevent
accidents .
The EA401 response time is 2-3 seconds (2 seconds in highway mode,
3 seconds in urban settings.) Detecting items like looking at the mirror
for too long, the alarm reaction time is 5 to 7 seconds, and then three
short alarms will sound. The retina shrinks smaller and smaller in the
8 seconds before people enter an unconscious state, so the system
can sound the alarm before it is too dangerous.
