Abstract

A system includes an active noise-reducing headset and an alert processor. The active noise reducing headset includes a communication module that establishes a wireless communication link, a microphone that generates a microphone signal in response to ambient noise, a speaker, a noise reduction circuit that generates a noise reduction signal in response to the microphone signal, and a control circuit that receives an incoming alert signal from the communication module and plays the alert signal over the speaker. The alert processor includes a second communication module that establishes the wireless link with the active noise-reducing headset, and a controller that receive an incoming alert signal, generates an alert notification in response to the alert signal, and transmits the alert notification to the active noise-reducing headset.

Claims

1. An electronic device, comprising:

a communication module to establish a wireless communication link with an active noise-reducing headset that is located remotely from the electronic device; and

a controller coupled to the communication module to receive an incoming audible alert signal that was audibly transmitted by an alert generation device, to analyze the audible alert signal to determine if it should be re-transmitted to the active noise-reducing headset, and to re-transmit the audible alert signal to the active noise-reducing headset via the wireless communication link in response to the analysis of the audible alert signal;

wherein the controller is to determine a source of the audible alert signal, and wherein the controller is to selectively transmit the audible alert signal in response to determining a source of the audible alert signal, the device further comprising a database that identifies actions to be taken in response to specified alert signals, wherein the database contains configuration information that specifies which of a plurality of headsets should receive notification of the specified alert signals.

2. The electronic device of claim 1, wherein the wireless communication link comprises an RF communication link.

3. The electronic device of claim 1, wherein the wireless communication link comprises a wireless local area network communication link, and wherein establishing the wireless communication link comprises establishing a transmission control protocol-internet protocol communication link between the communication module and the active noise-reducing headset.

4. The electronic device of claim 1, wherein the communication module is further to receive a voice command from the active noise-reducing headset, and wherein the controller is further to take action in response to the voice command.

5. A system comprising:

an active noise-reducing headset comprising;

a communication module to establish a wireless communication link;

a microphone to generate a microphone signal in response to ambient noise;

a speaker;

a noise reduction circuit coupled to the microphone and the speaker and to generate a noise reduction signal in response to the microphone signal; and

a control circuit to receive an incoming alert signal from the communication module and to play the alert signal over the speaker; and

an alert processor that is remote from the active noise-reducing headset, the alert processor comprising;

a second communication module to establish the wireless link with the first communication module of the active noise-reducing headset; and

a controller coupled to the second communication module and to receive an incoming audible alert signal that was audibly transmitted by an alert generation device, to analyze the audible alert signal to determine if it should be re-transmitted to the active noise-reducing headset, and to re-transmit the audible alert signal to the active noise-reducing headset via the communication link;

wherein the controller is to determine a source of the audible alert signal, and wherein the controller is to selectively transmit the audible alert signal in response to determining a source of the audible alert signal, the device further comprising a database that identifies actions to be taken in response to specified alert signals, wherein the database contains configuration information that specifies which of a plurality of headsets should receive notification of the specified alert signals.

6. The system of claim 5, further comprising:

the alert generation device to generate the audible alert signal.

7. The system of claim 5, wherein the active noise-reducing headset further comprises a voice over internet protocol module to establish a communication session with a remote terminal using an internet protocol.

8. The system of claim 5, wherein the active noise-reducing headset further comprises a voice recognition module to detect voice commands spoken by a user of the active noise-reducing headset and, in response to detecting the voice command, to send a signal indicative of the voice command to the control circuit.

9. A method, comprising:

receiving an audible electronic alert signal that was generated by an alert generation device;

analyzing the audible alert signal to determine if it should be transmitted to an active noise-reducing headset;

establishing a communication link with an active noise-reducing headset; and

re-transmitting the audible alert signal to the active noise-reducing headset via the communication link;

wherein the active noise-reducing headset is one of a plurality of active noise-reducing headsets, the method further comprising;

determining that the active noise-reducing headset should receive the alert signal;

wherein transmitting the alert signal to the active noise-reducing headset via the communication link comprises selectively transmitting the alert signal to the active noise-reducing headset and not transmitting the alert signal to others of the plurality of active noise-reducing headsets.

10. The method of claim 9, wherein the communication link comprises a wireless local area network communication link, and wherein establishing the communication link comprises establishing a transmission control protocol-internet protocol communication link with the active noise-reducing headset.

11. The method of claim 9, further comprising:

receiving a voice command from the active noise-reducing headset, and taking action in response to the voice command.
