F r a u n h o f e r I n s t i t u t e f o r D i g i t a l M e d i a Te c h n o l o g y I D M T Micro-Sleep Alerter – Prevents Drivers from Dozing off at the Wheel 1 photo acknowledgment: istockphoto.com/narvikk 1 1 Example of the Driver’s micro-sleep is among the most Cost-efficient Fraunhofer Micro-Sleep common causes of road traffic accidents. The Fraunhofer Micro-Sleep Alerter comes Alerter built into a car. The Micro-Sleep Alerter by Fraunhofer is an as a system on chip solution, which means assistance system that recognizes when the that the device works without an additional driver is about to doze off and produces an computer and can be produced cost- acoustic warning signal. Due to its compact efficiently. design the Micro-Sleep Alerter can be used in limited installation space. It is provided as a retrofit solution for all kinds of motor Technical details vehicles as well as an OEM solution. Components HDR-image-sensor, infrared illumination, Advantages system on chip processing unit (i. a. ARM architecture) Easy to use The Fraunhofer Micro-Sleep Alerter simply Hardware interfaces needs to be installed inside the vehicle optional for development purposes: similarly to a navigation system. After a USB, RS-232, LAN, CAN bus one-time configuration to the driver’s indiFraunhofer Institute for vidual requirements the system can be used Output without having to reconfigure it every time. acoustic warning on detecting microsleep Digital Media Technology IDMT and optical indicator for system status Applicable under any conditions Ehrenbergstr. 31 Due to the Micro-Sleep Alerter using Distance to user 98693 Ilmenau infrared illumination in combination with approx. 80 – 120 cm preadjusted Germany High Dynamic Range (HDR) camera sensors, Contact the device is working reliably at day and Headbox in the night, regardless of ambient light approx. 80 cm x 60 cm (at 100 cm user conditions.
