The silent alarm clock allows one to wake up without disturbing others and is aimed at couples who get up at different times in the morning. (It is also great for persons with hearing impairments.)
The alarm clock consists of a docking station and two vibrating wristbands you can set individually. One can push a button on the wristband: a long push turns the alarm off, a short push is for snooze. By placing or removing the wristband from the docking station a display appears in which the time can be set. During the day the wristbands are charged by induction. The docking station is optimized to allow the wristband to be quickly dropped.
