Interesting: Radar Tracks Your Sleep, Then Wakes You Up

via Robert E. Calem, techlicious.com
...there's a new alarm clock available that was designed to help you avoid sleep inertia by monitoring your sleep cycles—without a wearable sensor—and waking you up only when you're sleeping most lightly. It's called the Renew SleepClock by Gear4 ($199.95 on gear4.com) and combines a motion sensing iOS-device docking station-clock radio with a dedicated app that both wakes you and tracks your sleep habits over time. 

The hardware transmits two channels of 10GHz radio frequency signals in a 45-degree beam. These signals bounce off your body and are received back at the device by a sensor, which then processes them and passes the data to the app. 

The app uses the data to discern your breathing pattern and monitor your movements. Based on these interpretations, the app knows when you've fallen asleep, how long you've slept, when you're sleeping lightly or deeply, and when your sleep has been interrupted (for example, when you get out of bed for a 2 AM bathroom break). 

In the morning, the app uses all the captured data to determine the best time to wake you up within a one-hour time slot that you've preset in one of two built-in alarms. (more)
