This handy, pocket-size mobile transmission detector can sense the presence of an activated mobile phone from a distance of one and half meters. So it can be used to prevent the use of mobile phones in examination halls, confidential rooms, etc. There are existing models for the cell phone detectors which works when some transmission occurs from the phone. In this paper, we are proposing a dete...

Our research examined the effects of hands-free cell phone conversations on simulated driving. We found that driving performance of both younger and older adults was influenced by cell phone conversations. Compared with single-task (i.e., driving-only) conditions, when drivers used cell phones their reactions were 18% slower, their following distance was 12% greater, and they took 17% longer to...
