The Wake-Up Angel is an ear piece that vibrates when the wearer's head dips below 30 degrees. The idea is to keep you from nodding off at risky times such as during night driving, PowerPoint presentations and college lectures. The device comes in pink and black and looks enough like a hearing device that it wouldn't arouse suspicion in classrooms or boardrooms. No word on availability, though.
