The American's 24 hour, work hard, play hard culture makes it quite easy to deduce this as a natural occurrence.

Through the decades, he has explored the physiological effects related to the onset of sleep, hoping that he could figure out the realities behind the driver fatigue telltales. The commercial operators will gain more from utilizing such warning devices, so they have focused their efforts in the trucking industry. When the devices are made available for passenger cars, he does believe that the price for each unit will soon drop. For now, one gadget costs up to several thousands of dollars.

What type of fatigue [link widoczny dla zalogowanych] symptoms can the devices detect? To tell whether a person is going close to the danger zone, [link widoczny dla zalogowanych] the gadget will detect eye closures and long blinks. These [link widoczny dla zalogowanych] are perfect indicators of a behavioral chain. A driver's alertness level will usually diminish as he falls to sleep. For this reason, the alerting systems are built [link widoczny dla zalogowanych] to detect late stage sleep onset.
