In the ongoing battle against oversleeping, humanity has devised some clever alarm clocks. But for all their clever designs, most alarm clocks still suffer from a common drawback: the fact that they're not designed for multiple users. When one person's alarm goes off, other people in the room or throughout the house have to wake up too. Most alarm clocks have no way to selectively wake up one person and leave the other person undisturbed. Until now, that is.

Freshly launched on Kickstarter, Wake is a new breed of alarm that targets individual users and wakes up one sleeper without rousing others. Here's how it works. After it's mounted to the wall above the bed, the device uses an infrared temperature sensor and special body-tracking software to discern where each person is lying (without a camera). When it's time to wake one person up, Wake silently takes aim, rotates into position, and then directs a tight burst of light and sound at their face.

To keep from rousing other sleepers, the device uses a set of parametric speakers capable of focusing sound into a narrow beam. Think of it as a spotlight for noise. If Wake is pointed straight at your head you'll hear it loud and clear, but if you're outside of the beam's small radius, the sound will be extremely faint. Lucera Labs will ship the first batch in September 2015.

Possible Preaching Angles: (1) God calls you to wake up and live the Christian life, don't sleep through it; (2) The voice of God is personal and heard only by each individual, like Paul on the road to Damascus, to young Samuel in his sleep.
