Abstract
A hand-held wireless communication apparatus transmits and receives cellular radio signals that are compatible with a cellular network, and summons assistance during an emergency situation from multiple emergency response services. The apparatus comprises a lightweight and rigid housing with a cellular transmitter disposed therein. When activated, the cellular transmitter generates first outgoing cellular radio signals, such as paging messages, that contain information for a private emergency response service, and second outgoing cellular radio signals to communicate with a public emergency response service. The apparatus includes an emergency response button which is the sole means of activating the transmitter. When pressed, the emergency response button alone activates the transmitter to cause the transmitter to generate the first and second outgoing cellular radio signals. The apparatus also includes receiver means for receiving incoming cellular radio signals over the cellular network from at least one of the emergency response services, and for converting the incoming cellular radio signals into audio signals. An audio output device receives the audio signals from the receive…
