Abstract
Abstract A communication system including a short range hand held transmitter having the capability of transmitting an intelligence signal on one basic frequency and a steady signal on a second separate basic frequency to a vehicle located a short distance away, and a transceiver-input unit which is plugged into a standard transceiver in the vehicle, which unit is responsive to said one frequency signal to cause said transceiver to broadcast to a remote point the intelligence signal. Said unit is responsive to said second frequency signal to turn on the vehicle siren and lights, and also to change said constant signal into brief coded signals which are broadcasted by said transceiver at regular intervals with each brief coded signal being no more than 33 1/3 of the interval between two brief coded signals. Said units turns on the transceiver one-quarter second before the beginning of the brief coded signal and turns the transceiver off immediately upon conclusion of the brief coded signal. The transmitter broadcasts a carrier wave which is pulse coded around said one basic frequency by a subcarrier which is frequency modulated by the intelligence input into the transmitter.
