Abstract: This invention relates to personal protective devices, particularly as combined with cellular telephones. In one embodiment of the invention, a cellular telephone is modified to deliver a personal protective spray, such as pepper spray, mace or dog spray. Upon activation of the spray, the cellular telephone automatically alerts law enforcement or other emergency response personnel, such as by dialing 911, “On Star”, or any number chosen by the cellular phone owner. Additionally, the cellular telephone/protective device combination further includes a global positioning system (GPS) enabling emergency response personnel to immediately locate the individual that has activated the system. In another embodiment, a cellular telephone is combined with tools for tradesmen, including a refillable pen, temperature and humidity sensor, a reversible slot/Phillips head screwdriver, an electrical current tester probe, a temperature/humidity sensor with display, and a electrical current indicator.
