Product Description
According to published studies and test results, the driver’s
vigilance level decreases (i.e. hypo-vigilance) due to long
hours driving on highways. The DFD-100 is a driver
hypo-vigilance(HPV)/ fatigue detector that detects driver’s
heart rate change to determine the driver’s HPV/ fatigue .
The DFD-100 issues a warning whenever the driver’s
vigilance level drops below the set-up limit.
The DFD-100 is based on the use of non-contact heart rate
sensing technology and a patented HPV/fatigue detection
algorithm. No electrode patches in direct contact with the
skin are required. The device is fitted to the driver's seat
belt and the device is ready to start operating when the
driver’s seat belt is fastened.
