Anti Sleep Alarm
How does Anti-sleep Alarm StopSleep work?
Anti-sleep alarm measures the conductivity of the skin (electrodermal activity - EDA). EDA reflects brain activity. The fact that the electrical conductivity of the skin varies, depending on the activity of the brain was found about hundred years ago. Many developers based on this discovery, which led to hundreds of patents. Among others, the function of Polygraphes - the lie detector - based on this principle, the device fixes the changes in skin conductance of those tested in answering the questions.
The processing algorithm of the signal, which is used in the anti sleep alarm StopSleep is used in a reliable detection of the following two states:
- Falling asleep, is characterized by a strong signal decrease
- Reduction of reaction, which can be called by the start of drowsiness, deep thought or simply boredom.
Both conditions are dangerous for the driver, and therefore generate anti sleep alarm StopSleep in these cases warning signals (sound, vibration).
So that the fatigue detection to work properly it is important start to use anti sleep alarm StopSleep in time, when you are still active, and not when you are tired already. The fatigue detection takes 3-5 minutes to measure your current brain activity and then your fatigue is estimated from this level. The anti-sleep alarm don't need to drive specific number of miles, you can put it on before you drive. Stopleep controls the level of your response and can even be helpful for short distance.
