DRIVER FATIGUE DETECTOR
First Claim
1. A device for alerting a driver of an automotive vehicle as to the onset of fatigue, characterized by eyelid droop, head droop and a like condition wherein the eyes of a driver are not directed straight ahead onto the road, said device comprising:
- a housing adapted to be affixed to a portion of the automotive vehicle so as to be located at the upper periphery of the field of vision of the driver, said housing comprising;
an indicator lamp viewable by the driver in the upper periphery of the field of vision of the driver, an electrical control circuit for controlling illumination of said indicator lamp so as to provide illumination thereof after passage of a predetermined time interval, a driver controlled reset switch for providing resetting of said time interval upon depression thereof by the driver; and

Abstract
A device is provided for alerting a driver of an automotive vehicle as to the onset of fatigue, characterized by eyelid droop, head droop and a like condition wherein the eyes of the driver are not directed straight ahead onto the road. The device includes a unit adapted to be affixed to the sun visor of the automotive vehicle so as to be located at the upper periphery of the field of vision of the driver. The unit includes a light element, preferably a red light emitting diode (LED), viewable by the driver in the periphery of the field of vision of the driver. A control circuit controls the LED so as to provide illumination thereof after a predetermined time interval. A driver controlled pushbutton controller connected to the control circuit provides initial energization of the LED while a reset pushbutton provides resetting of the time interval upon depression thereof by the driver. An alarm sounds when the LED has been illuminated after the passage of the predetermined time interval and the push button controller has not been depressed after passage of a further predetermined time period.
