A Revolutionary Alarm Clock
When we sleep, we move in a continuous cycle, from a deep sleep to brief periods when we're almost awake, and then back into a deep sleep again. This pattern repeats itself throughout the night. The average adult experiences four to five full sleep cycles over an eight-hour period. Each cycle lasts about 90 to 110 minutes and is made up of five different stages. During the first stage of your sleep cycle, you sleep lightly. At stage two, your sleep gets progressively deeper, and at stages three and four, also known as "Delta sleep," you sleep most heavily. The fifth stage of sleep, also known as REM (rapid eye movement) sleep, is marked by extensive physiological changes, such as accelerated respiration, increased brain activity, rapid eye movement, and muscle relaxation.

During these stages, there are brief moments when you're nearly awake. The Sleeptracker -- one of Time Magazine's Best Inventions of 2005 -- is designed to find those almost-awake moments within the sleep cycle. When you set an "alarm window" (a period of time within which you want to be awoken) on the Sleeptracker, the monitor will continuously monitor your body for signals that you are nearly awake, and the monitor's customized alarm clock will go off within the time frame that you've set. Instead of waking up groggy and irritable because you were woken up during a deep sleep, you'll wake up feeling refreshed and energetic.

A Customized Alarm Clock
The Sleeptracker is worn like an everyday wristwatch and is ideal for anyone who wants to start the day fresh and energized. Frequent travelers crossing time zones, business people looking for that extra edge, students with fluctuating schedules, and moms needing to be at the top of their game first thing in the morning are all ideal users of the Sleeptracker.

The Sleeptracker is also designed to help you understand how you sleep at night. Using an accelerometer, the Sleeptracker monitors for brief moments of movement (typically lasting less than 30 seconds) during your lighter stages of sleep and records them. The next morning, you can review this data to better understand your sleep cycles. This information will help you adjust your habits so you can get a better rest.

This chart illustrates a typical adult sleep pattern. As the chart indicates, several almost-awake moments may occur within a sleep cycle. The Sleeptracker is designed to wake you up during one of these moments within your pre-set "alarm window," so you wake up refreshed and energized.
