The United States National Highway Traffic Safety Administration estimates drowsiness and fatigue are the principal causes in approximately 100,000 police-reported crashes, injuring 71,000 people and costing $12.5 billion in monetary loss each year.
The primary objective of the Stay-Awake Monitor is to keep tired individuals awake. When a person falls asleep, their heart rate slows down. This device compares the user's heart rate to a target heart rate. If the heart rate slows down too much, lights and alarms go off, alerting the user. Turning the alarms off requires physical motion, waking the user up and raising their heart rate. |
