Abstract

An apparatus for smoke detection having an image sensor may be tested using image or pattern recognition, or facial gesturing without having to climb a ladder or chair to initiate the test, or be uncomfortably close to the smoke detector apparatus during initiation of the testing thereof. Carbon monoxide (CO) and/or carbon dioxide (CO₂) monitoring and alarm may also be incorporated into this apparatus. Other control functions may also be initiated with image or pattern recognition, or facial gesturing such as audio features associated with the smoke detector apparatus such as networked speakers for distribution of music, intercom, telephone, and/or doorbell annunciation.

Claims

1. An apparatus for detecting smoke and having pattern recognition capabilities, comprising:

a logic device;

a smoke sensor coupled to the logic device;

an image sensor coupled to the logic device and configured to detect a pattern on a substrate;

a communications interface coupled to the logic device;

an audible alarm generator coupled to the logic device; and

a power supply coupled to and powering the logic device, communications interface and the audible alarm generator;

wherein when the smoke sensor detects smoke the logic device generates at least one smoke alarm tone through the audible alarm generator, and a smoke alarm signal through the communications interface; and

wherein the logic device is configured to initiate a smoke alarm testing in response to detection of the pattern by the image sensor.

2. The apparatus according to claim 1, wherein the audible alarm generator comprises a speaker coupled to an audio amplifier that is coupled to the logic device.

3. The apparatus according to claim 1, wherein the communications interface is coupled to a wired communications bus.

4. The apparatus according to claim 3, wherein the wired communications bus is an Ethernet local area network.

5. The apparatus according to claim 1, wherein the communications interface is a wireless interface coupled to a radio frequency antenna.

6. The apparatus according to claim 5, wherein the communications interface is adapted to communicate with a wireless kcal area network (WLAN).

7. The apparatus according to claim 1, wherein the smoke sensor is an ionization chamber smoke sensor.

8. The apparatus according to claim 1, wherein the smoke sensor is an optical smoke sensor.

9. The apparatus according to claim 1, further comprising a microphone and an audio interface coupled to the logic device and providing an audio input.

10. The apparatus according to claim 1, further comprising a carbon monoxide sensor coupled to the logic device.

11. The apparatus according to claim 1, further comprising a carbon dioxide sensor coupled to the logic device.

12. The apparatus according to claim 1, further comprising an image acquisition indicator that indicates when an image is present in the image sensor.

13. The apparatus according to claim 1, wherein the logic device comprises a microcontroller.

14. The apparatus according to claim 1, wherein the logic device is selected from the group consisting of a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), and a held programmable gate array (FPGA).
