Active anti-dazzle device for the drivers of cars and other motor vehicles having an electro-sensitive screen |
摘要 |
An electrical circuit including an optic sensor generating an output sensing signal proportional to a value of a luminosity intercepted in the sensor's field of reception at a specific angle, a measuring/comparing circuit for comparing the output sensing signal with a preset threshold value so as to transmit an actuating signal to a power supply unit of an electro-sensitive screen which responds to the transmission by entering a state of becoming partially darkened or colored. The electro-sensitive screen enters into a state of total transparency when there is no actuating signal transmitted or when the actuating signal ceases its transmission.
