So, the only way to wake up and feel refreshed is to drink a cup of strong coffee. People all over the world face this problem.

But, thanks to modern technologies and scientific knowledge we have got a great solution. A unique alarm clock Sleeptracker is clever enough as it takes into account your sleep phases and knows when it’s the best time for you to get up.  Your sleep is divided into different cycles, such as long deep sleep phases, when it’s rather difficult to wake you up and you even don’t move and short quick sleep phases of your brain activity, when you see dreams.

You need just to set the time, when you go to bed and the time interval of your usual awakening and the alarm will detect the right moment from this interval according to your movements during the sleep.

An alarm clock is a timepiece which most people treat very controversially: on the one hand we all hate alarm clocks whose annoying sounds burst into our sweetest morning dreams but on the other hand they help us not to miss events important for us. This article is dedicated to smart alarm-clocks that wake their owners in an original way.

Paradox of Sleep

One night an American businessman Lee Loree was lying in his bed reading a book. Next to him his wife began to toss. He asked her something; she answered and fell asleep again. About ten minutes later Lee addressed to his wife once again and in the same tone but she didn’t reply. It was very interesting to curious mister Loree why sleeping his wife reacts in different ways to the same irritants. So he started a research: in daytime he was reading about the nature of sleep and at night… At night he was experimenting with his wife.

His research resulted in a paradoxical conclusion: generally it’s better to rip a person off several minutes of sleep and to wake him or her up in the right moment than to let him or her have some more precious minutes of sleep. Having understood this fact, Lee Loree decided to invent a device that would wake one up in the right moment of time. He worked on the device together with an engineer and a somnologist. Six years later the work resulted in the creation of a unique alarm clock - Sleeptracker.

Sleeptracker looks as a traditional digital wristwatch. While owners of traditional alarm clocks set only the time for the wake-up, owners of the Sleeptracker also have to set the period of time preceding the time of the wake-up. During this interval the Sleeptracker starts to signal if the sleeper starts to toss in bed. Inside the case of the clock there is an accelerometer which recognized moves of a human’s hand (that’s why the device is rather massive) and sends a signal to the control unit. If the moves are recognized during the set interval of time the clock goes off. If this happens outside the set period the time when the sleeper moved rather actively is stored in the memory unit. So in the morning it is possible to check how often sleep phases were changing. With the help of the Sleeptracker you can keep a sleep-diary which will allow you to discover a lot of interesting things about your night life.

Alarm Clock for a Couple

aXbo is one more smart alarm clock developed and created by an Austrian - Boris Eis. The inventor of the smart alarm clock says: “Being a student I noticed that sometimes I woke up easily but sometimes with difficulty regardless of duration of sleep. And that was annoying.� So in the mid 1990s Eis decided to find out the reason for this phenomenon and discovered that it’s better to wake one up when he or she starts to toss.

The аXbo alarm clock work practically in the same way as the Sleeptracker. But instead of the wristwatch itself users put special bracelets on their wrists. The bracelets are equipped with a built-in sensor which is connected with the alarm clock wirelessly. The advantage of the aXbo is that it can wake up two people – and while he wakes up one of them the other is not being disturbed.

Boris Eis is planning to create a new version of his alarm clock which will wake the sleeper up in the end of the fast sleep (or rapid eye movement). So people will get the opportunity to wake up cheerful and to preserve the recollections about the last dream they saw that night.
