Emergency alert messages are recognizable only when the receiving device is active or in the “on” state of operation. With many electronics devices a sleep mode is often available that allows it to “listen” for a wake up signal. An example of this is the system that is often utilized with personal computer systems; the system often enters a sleep mode and is reawakened when the keyboard or mouse is touched. Radio receivers can be designed to behave in a similar fashion. That is it is in sleep mode until a unique signal is received and upon reception of that signal the radio receiver awakens. This operation would allow for radio receivers to turn on at the instance an emergency alert signal is sent.

The embodiment of this idea is that typical AM and FM radio broadcast signals are utilized to carry unique sequences of tones or digital codes that would be received and decoded by a radio receiver that is in sleep mode and awakens to process the emergency alert. The operation is similar to an alarm clock radio that turns on the radio when a certain set time is reached.

This invention can also be used for non "emergency" civil information such a road closure and detour details. In this case a responder to a traffic situation could set up a temporary transmitter and play a loop of information useful to frustrated motorists. Car radios could be set to respond to various levels of information(s) provided. Such levels (or genres) might include life threatening situations, mobi...
