Abstract

A GPS microphone, which is adapted for incorporating a communication system, includes a speaker-microphone set, a radio frequency transmitter communicatively networked with the communication system through radio frequency signals, and a GPS controller electrically connected with the radio frequency transmitter to encode positioning data into one or more RF positioning signals in form of audio signals wherein when the GPS controller is triggered, the radio frequency transmitter is activated to transmit RF positioning signals to the communication system.

Claims

1. A GPS communication apparatus for transmitting a positioning data to a communication system, comprising a GPS-microphone which comprises:

a speaker-microphone set which comprises a microphone, a speaker, and a PTT (Push-To-Talk) circuitry arranged in such a manner that when said PTT circuitry is triggered to activate said microphone in a transmit mode, said microphone is capable of receiving and encoding a voice message into an audio signal,

a radio frequency transmitter for communicatively networking with said communication system through radio frequency signals, and

a GPS controller electrically connected with said radio frequency transmitter to encode positioning data into one or more RF positioning signals in form of audio signals, wherein when said GPS controller is triggered, said radio frequency transmitter is activated for transmitting said RF positioning signal to said communication system, wherein said GPS controller is activated when said PTT circuitry is triggered in such a manner that said audio signal from said speaker-microphone set and said RF positioning signals from said GPS controller are combined to form an information signal for transmitting to said communication system.

2. The GPS communication apparatus, as recited in claim 1, wherein said radio frequency transmitter further generates an identification signal, which is in form of an audio signal, with respect to said speaker-microphone set, wherein when said RF positioning signals are transmitted from said radio frequency transmitter, said identification signal is combined with said RF positioning signals for transmitting to said communication system.

3. The GPS communication apparatus, as recited in claim 1, wherein said radio frequency transmitter is a radio transmitting device adapted to send and receive said radio frequency, wherein said radio frequency transmitter functions as a wireless communication link between said GPS-microphone and said communication system.

4. The GPS communication apparatus, as recited in claim 1, wherein said communication system comprises a control center which comprises a signal receiver communicatively networking with said GPS-microphone through said radio frequency signals for receiving said information signal form said GPS-microphone, means for decoding said information signal from said receiving means, and a processor center converting said RF positioning signals back to said positioning data.

5. The GPS communication apparatus, as recited in claim 2, wherein said communication system comprises a control center which comprises a signal receiver communicatively networking with said GPS-microphone through said radio frequency signals for receiving said information signal form said GPS-microphone, means for decoding said information signal from said receiving means, and a processor center converting said RF positioning signals back to said positioning data.

6. The GPS communication apparatus, as recited in claim 3, wherein said communication system comprises a control center which comprises a signal receiver communicatively networking with said GPS-microphone through said radio frequency signals for receiving said information signal form said GPS-microphone, means for decoding said information signal form said receiving means, and a processor center converting said RF positioning signals back to said positioning data.

7. A process of transmitting a positioning data to a communication system from a GPS-microphone which comprises a speaker-microphone set, a radio frequency transmitter and a GPS controller, wherein said speaker-microphone set comprises a PTT circuitry arranged to activate said speaker-microphone set and said GPS controller is activated when said PTT circuitry is triggered, wherein the process comprises the steps of:

(a) communicatively networking said radio frequency transmitter to said communication system through radio frequency signals;

(b) encoding positioning data, by said GPS controller, into one or more RF positioning signals in form of audio signals and combining said RF positioning signals with an audio signal from said speaker-microphone set before said RF positioning signals are sent to said communication system; and

(c) activating said radio frequency transmitter to transmit said RF positioning signals to said communication system and generating an identification signal, which is in form of audio signal, with respect to said speaker-microphone set, wherein said identification signal is combined with said RF positioning signals to transmit to said communication system when said RF positioning signals are transmitted from said radio frequency transmitter.

8. The process, as recited in claim 7, further comprising a step of decoding said RF positioning signals to a readable positioning data at said communication system.

9. A process of transmitting a positioning data to a communication system from a GPS-microphone which comprises a speaker-microphone set, a radio frequency transmitter and a GPS controller, wherein the process comprises the steps of:

(a) communicatively networking said radio frequency transmitter to said communication system through radio frequency signals;

(b) encoding positioning data, by said GPS controller, into one or more RF positioning signals in form of audio signals and combining said RF positioning signal with an audio signal from said speaker-microphone set before said RF positioning signals are sent to said communication system, wherein said GPS controller is preset to be activated for receiving and positioning data for a period of time; and

(c) activating said radio frequency transmitter to transmit said RF positioning signals to said communication system and generating an identification signal, which is in form of audio signal, with respect to said speaker-microphone set, wherein said identification signal is combined with said RF positioning signals to transmit to said communication system when said RF positioning signals are transmitted from said radio frequency transmitter.

10. The process, as recited in claim 9, further comprising a step of decoding said RF positioning signals to a readable positioning data at said communication system.
