Abstract

Embodiments of the present disclosure provide methods and systems for enabling remote alarm hushing with acoustic presence verification. Acoustic presence verification is used to assure that a device attempting to remotely deactivate an alarm is located within a certain distance of an alarming device before allowing the alarm to be hushed. Acoustic presence can be established through emission and monitoring of ultrasonic acoustic signals. The ultrasonic acoustic signals may be transmitted at a frequency that exceeds human hearing such as, for example, between 18 KHz and 22 kHz. Such ultrasonic signals have a relatively short range and are unable to penetrate walls and floors, thus providing an effective tool for ensuring that the device attempting to remotely hush an alarming device is within a line-of-sight of the alarming device.

Claims

1. An electronic device associated with a structure and operative to modify its operation in response to instructions originating from a remote device, the electronic device comprising:

wireless communications circuitry;

a microphone; and

a processor electrically coupled to the wireless communications circuitry and the microphone, the processor operative to;

receive an instruction originating from the remote device via the wireless communication circuitry;

verify presence of the remote device using the microphone; and

execute the instruction when the presence of the remote device is verified with the microphone.

2. The electronic device of claim 1, wherein the processor is operative to:

prevent execution of the instruction when the presence of the remote device is not verified with the microphone.

3. The electronic device of claim 2, wherein the remote device is located external to the structure and wherein the instruction is received via the wireless communications circuitry by way of an Internet Service Provider.

4. The electronic device of claim 1, wherein when the processor is verifying presence of the remote device, the processor is further operative to:

receive an audio signal using the microphone, wherein the audio signal comprises data encoded therein;

decode the received audio signal to obtain the data; and

process the data obtained from the decoded audio signal.

5. The electronic device of claim 1, wherein the wireless communications circuitry communicates with the remote device using direct point-to-point wireless communications.

6. The electronic device of claim 1, wherein the wireless communications circuitry communicates with the remote device using server based wireless communications.

7. The electronic device of claim 1, wherein the processor is further operative to:

assess whether the received instruction is of a type that requires acoustic verification;

execute the received instruction when the received instruction is not of the type that requires acoustic verification; and

when the received instruction is of the type that requires acoustic verification, verify presence of the remote device using the microphone before executing the instruction.

14. The method of claim 1, further comprising:

assessing whether the received instruction is of a type that requires acoustic verification;

executing the received instruction when the received instruction is not of the type that requires acoustic verification; and

when the received instruction is of the type that requires acoustic verification, verifying presence of the remote device using the microphone.

8. A method for operating an electronic device associated with a structure, the electronic device comprises wireless communications circuitry, a microphone, and a processor electrically coupled to the wireless communications circuitry and the microphone, method comprising:

receiving an instruction originating from a remote device via the wireless communication circuitry;

verifying presence of the remote device using the microphone; and

executing the instruction when the presence of the remote device is verified with the microphone.

9. The method of claim 8, further comprising:

preventing execution of the instruction when the presence of the remote device is not verified with the microphone.

10. The method of claim 9, wherein the remote device is located external to the structure and wherein the instruction is received via the wireless communications circuitry by way of an Internet Service Provider.

11. The method of claim 8, wherein when the verifying presence of the remote device further comprises:

receiving an audio signal using the microphone, wherein the audio signal comprises data encoded therein;

decoding the received audio signal to obtain the data; and

processing the data obtained from the decoded audio signal.

12. The method of claim 8, further comprising communicating with the remote device using direct point-to-point wireless communications.

13. The method of claim 8, further comprising communicating with the remote device using server based wireless communications.

15. A first electronic device for use in communicating with at least a second electronic device associated with a structure, the first electronic device comprising:

wireless communications circuitry;

audio generation circuitry;

a processor; and

memory storing instructions that, when executed, are configured to cause the processor to;

receive, from a user, an input to issue an instruction to the second electronic device;

transmit the instruction using the wireless communications circuitry; and

emit, via the audio generation circuitry, an audio signal, wherein the audio signal is used to confirm presence of the first electronic device to the second electronic device.

16. The first electronic device of claim 15, wherein the instructions are configured to cause the processor to:

encode data into the audio signal.

17. The first electronic device of claim 15, wherein the instructions are configured to cause the processor to:

simultaneously emit the audio signal in conjunction with transmission of the instruction.

18. The first electronic device of claim 15, wherein the instructions are configured to cause the processor to:

receive, via the wireless communications circuitry, confirmation of receipt of the instruction by the second electronic device.
