Abstract

Each one of a plurality of communication devices that are located at different physical locations contains an acoustic sensor for monitoring the physical location of its communication device, and reports acoustic events detected by its acoustic sensor to a manager. The manager displays a map which shows the physical locations, the events detected by the acoustic sensor in each communication device, sent notification messages, and received response messages.

an audio signal, an occupant input from a keypad, and an occupant input from a touch screen.

5. The system of claim 2, wherein the manager is adapted to display the response message on the map in conjunction with the locations.

6. The system of claim 2, wherein the manager is adapted to respond to the response message by sending a second one of the notification messages to the selected one of the devices.

7. The system of claim 6, wherein the manager is adapted to display the second one of the notification messages on the map in conjunction with the locations.

8. The system of claim 6, wherein the one of the notification messages contains occupant instructions.

9. The system of claim 6, wherein the response message contains an occupant status.

10. The system of claim 6, wherein the second one of the notification messages contains an evacuation route.

11. The system of claim 1, wherein the one of the notification messages contains an evacuation route selected by the manager based on a location of at least one of the events;

and wherein at least one of the selected ones of the devices is a cellular telephone.

12. The system of claim 1, wherein the manager is adapted to respond to not receiving a response message by instructing one of the devices to monitor for an additional event.

13. The system of claim 12, wherein the manager is adapted to respond to detection of the additional event by the one of the devices by sending a second notification message.

14. The system of claim 1, wherein the event is an item selected from a group comprising:

a temperature, a change in temperature, a gunshot, a sound, an explosion, an impact, a fire, a voice recognition, breaking of a window, an accelerometer detecting movement, a sound of wind, and a lack of a response from a communication device.

15. A method for managing acoustic events comprising:

a. acoustically monitoring a physical location of each of a plurality of communication devices;

b. reporting one or more events detected by the monitoring;

c. responding to the reporting by sending at least one notification message to at least one of the devices;

d. displaying a map showing the locations of the devices; and

e. displaying on the map at least one of the events and at least one of the notification messages in conjunction with the locations.

16. The method of claim 15, further comprising:

responsive to the one of the notification messages, receiving a response message from a selected one of the devices.

17. The method of claim 16, further comprising the step of:

selecting one of a plurality of different types of notification messages and sending the notification message of the selected type.

18. The method of claim 16, wherein the response message is based on at least one item selected from a group comprising:

an audio signal, an occupant input from a keypad, and an occupant input from a touch screen.

19. The method of claim 16, further comprising the step of:

displaying the response message on the map in conjunction with the locations.

20. The method of claim 16, further comprising:

responsive to the response message, sending a second one of the notification messages to the selected one of the devices.

21. The method of claim 20, further comprising:

displaying the second one of the notification messages on the map in conjunction with the locations.

22. The method of claim 20, wherein the one of the notification messages contains occupant instructions.

23. The method of claim 20, wherein the response message contains an occupant status.

24. The method of claim 20, wherein the second one of the notification messages contains an evacuation route.

25. The method of claim 15, wherein the one of the notification messages contains an evacuation route selected based on a location of at least one of the events;

and wherein at least one of the selected ones of the devices is a cellular telephone.

26. The method of claim 15, further comprising:

in response to not receiving a response message, instructing one of the devices to monitor for an additional event.

27. The method of claim 26, further comprising:

in response to detecting the additional event by the acoustic sensor in one of the devices, sending a second notification message.

28. The method of claim 15, wherein the event is an item selected from a group comprising:

a temperature, a change in temperature, a gunshot, a sound, an explosion, an impact, a fire, a voice recognition, breaking of a window, an accelerometer detecting movement, a sound of wind, and lack of a response from a communication device.

b. means for reporting one or more of the events detected by the monitoring;

c. means for responding to the reporting by sending at least one notification message to at least one of the devices;

d. means for displaying a map showing the physical locations of the devices; and

e. means for displaying on the map at least one of the events and at least one of the notification messages in conjunction with the locations.

31. A method for managing acoustic events comprising:

a. acoustically monitoring a physical location of each of a plurality of communication devices;
