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.
The camera, which is mounted in the driver's field of vision, uses image analysis software to determine if the driver is fatigued or distracted. Thanks to its small size and integrated lens, which has a 40-degree angle of illumination, the SFH4236 type LED can be easily installed in the dashboard of a vehicle, for example, and directly illuminate the driver from the front, without producing shadows.
IR-LEDs of this output class with integrated lenses have not been available until now. According to German Traffic Safety Advisory Board statistics, about 1,300 people are killed in single-vehicle accidents on Germany's roads every year - accidents involving no other road users.
It is estimated that at least 25 percent of these accidents are caused by microsleep. The fatigue detection system featuring the IR-LED from Osram Opto Semiconductors could become a lifesaver in such cases.
Other areas of application for such high-performance IR-LEDs in motor vehicles include seat occupancy recognition, night vision systems, short-range surroundings detection, and monitoring drivers' blind spots. The IR-LED has a service life of tens of thousands of hours, many times more than the average number of hours that a vehicle is operated in its service life. In other words, it will never have to be replaced during the average life of a vehicle.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
