Abstract: A gunshot detection system includes a firearm and a communication device. The firearm includes a transceiver circuit that detects the discharge of an ammunition round. Upon the discharge occurring, the transceiver circuit emits an electromagnetic signal. The electromagnetic signal is received by the communication device, which may be a cellular telephone or two-way radio. The communication device is equipped with a geographic location sensor, like a GPS receiver for example. Software within the communication device then causes an informational message that includes geographic information to be transmitted to a remote device. For instance, when a police officer discharges his firearm, an informational message stating “Officer 1234 has just fired 3 shots at the intersection of Cucumber and Vine—please respond” may be transmitted. The informational message may change as information like the geographic location change.

Abstract: A hand tool, like a handgun, is provided having a wireless, push to talk switch embedded therein. When the push to talk switch is actuated, a signal is sent to an external, nearby two-way communication device. The signal is capable of actuating the microphone of the two-way communication device and causing transmission. In so doing, a user may use the communication device while keeping two hands on the tool. For example, when a police officer has two hands on a firearm, the police officer may press the push to talk button on the firearm, thereby allowing him to call for assistance with a radio or mobile telephone without having to take his hands off the firearm.
