A new infrared light-emitting diode (IR-LED) from the Siemens subsidiary Osram Opto Semiconductors is designed to help recognize the hazardous microsleep that affects motorists. In addition to the IR-LED, this requires a suitable camera with a CMOS sensor. The sensor detects IR light at a wavelength of 850 nanometers, which isn't visible to the human eye, and analyzes the image of the driver that is captured by the camera. And it all takes place unnoticed by the driver - even at night.
