Abstract

Systems and methods are provided for the adaptive detection of audio alarms. A system comprises a microphone configured to receive a series of sounds, a memory configured to store a defined set of alarm templates, a communications network interface, and a processor. The processor is configured to receive and analyze sounds for alarm or background sound characteristics and compare them to a defined set of alarm templates stored in the memory. If not contained in the defined set of alarm templates previously stored in the memory, new alarm templates are learned and stored. An alert is then transmitted to a client device that an audio alarm has been recognized.

First claim

What is claimed is:

1. A system for adaptive detection of audio alarms, comprising:
a microphone configured to receive a series of sounds;
a communications interface operably coupled to the microphone and configured to communicate with an external network;
a memory configured to store a defined set of alarm templates; and
a processor operably coupled to the memory and the communications interface and configured to:
analyze the series of sounds to determine an alarm characteristic;
compare the alarm characteristic to the defined set of alarm templates stored in the memory;
store the compared alarm characteristic in the memory based on the defined set of alarm templates previously stored in the memory;

transmit an alert to a client device that an audio alarm has occurred;
receive user input from a client device and identify the audio alarm based on the user input; and
generate and store in the memory an alarm template for the alarm characteristic based on the user input.

2. The system for adaptive detection of audio alarms of claim 1 , wherein the processor is further configured to receive series of sounds from a plurality of microphones.

3. The system for adaptive detection of audio alarms of claim 1 , wherein the processor is further configured to analyze a series of sounds from a plurality of systems for adaptive detection of audio alarms.

4. The system for adaptive detection of audio alarms of claim 1 , wherein the processor is further configured to analyze background sound characteristics.

5. The system for adaptive detection of audio alarms of claim 1 , wherein the processor is further configured to transmit an alarm template to a central library using the communications interface and to receive an alarm template from the central library using the communication interface.

6. The system for adaptive detection of audio alarms of claim 1 , wherein the processor is further configured to replay the audio alarm at a client device.

7. The system for adaptive detection of audio alarms of claim 1 , wherein the processor automatically executes a programmed action based on the alarm characteristic.

8. A method for adaptive detection of audio alarms, comprising:
receiving, at a processor, a series of sounds from a microphone;
analyzing, at the processor, the series of sounds to determine an alarm characteristic;
comparing, at the processor, the alarm characteristic to a defined set of alarm templates stored in a memory;
storing, at the processor, the compared alarm characteristic in the memory based on the defined set of alarm templates previously stored in the memory;
transmitting, at the processor, an alert to a client device that an audio alarm has occurred;

receiving user input at a client device and identifying the audio alarm based on the user input; and
generating and storing in the memory an alarm template for the alarm characteristic based on the user input.

9. The method for adaptive detection of audio alarms of claim 8 , further comprising receiving a series of sounds from a plurality of microphones.

10. The method for adaptive detection of audio alarms of claim 8 , wherein analyzing the series of sounds received is performed by correlating a plurality of systems for adaptive detection of audio alarms.

11. The method for adaptive detection of audio alarms of claim 8 , further comprising detecting and analyzing background sound characteristics.

12. The method for adaptive detection of audio alarms of claim 8 , wherein transmitting an alarm template to and from a central library is performed by a communications interface.

13. The method for adaptive detection of audio alarms of claim 8 , wherein comparing the alarm characteristic includes replaying the audio alarm for a user at a client device to identify the audio alarm.

14. The method for adaptive detection of audio alarms of claim 8 , wherein analyzing the alarm characteristic includes automatically executing a programmed action.

15. A system for adaptive detection of audio alarms, comprising:
a microphone configured to receive a series of sounds;
a processing device coupled to the microphone and configured to receive and process the series of sounds and transmit an alert to a client device; and
a client device configured to receive data from the processing device, and configured to identify an audio alarm associated with the series of sounds based on input received from a user, and transmit the identity of the audio alarm to the processing device;
wherein the processing device is further configured to generate and store an alarm template based on the identity of the audio alarm.

16. The system for adaptive detection of audio alarms of claim 15 , wherein the system is further configured to receive the series of sounds from a plurality of microphones.

17. The system for adaptive detection of audio alarms of claim 15 , wherein the system is further configured to analyze a series of sounds received from a plurality of systems for adaptive detection of audio alarms.
