The trouble with noisy alarm clock is the fact that they can wake up the whole family when one person has to wake up. So how to use one without disturbing the environment? Chirp designer seems to have the answer.
Chirp is an alarm clock designed to wake original one person at a time. Chirp includes a clock and a kind of clip that detaches from the base. This clip is fixed on the pillow and vibrates when it is time to wake up. The clock communicates with the clamp remotely using signals. The device vibrates continuously and there is only one way to stop it: put the clip in its original location on the base. When the person supposed to be awakened by the vibrations a sleep too heavy and does not respond after a certain period of time, an alarm goes off to wake him up in a conventional manner.
