| 20100035632 | System and method for detecting use of a wireless device while driving - A system for detecting the use of wireless devices such as a mobile phone, personal digital assistant (PDA), or pagers in a moving vehicle receives wireless signals inside a vehicle using a radio frequency (RF) sensor(s) and converts the RF signals into voltage signals. The voltage signals are then compared with known waveforms to determine if the wireless signals indicate a received call, if the received call is answered, a transmitted call, an SMS text message, data associated with internet browsing on a wireless device, or Bluetooth activity. | 02-11-2010 |
