Abstract

A particular smart hazard detector may itself function as a guide during a process of installation of the same at an installation location. Additionally, the installation location of the particular smart hazard detector may play a central role in how various settings of the smart hazard detector are defined and adjusted over time.

First claim

What is claimed is:

1. A method for guiding installation of a hazard detector, comprising:
receiving, by the hazard detector during installation at a particular location within a residence, an input command to test whether an instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards;
implementing, by the hazard detector in response to receiving the input command, a test sequence to determine whether the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards; and
outputting, by the hazard detector, a particular notification during installation at the particular location when it is determined that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards, based upon readings of at least one component of the hazard detector.

2. The method of claim 1 , further comprising:
determining, based upon readings of a proximity sensor of the hazard detector, that the instant placement of the hazard detector is within a prohibitive distance from one or more wall or ceiling surfaces; and
in response to the determining, outputting the particular notification to indicate that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards.

3. The method of claim 2 , wherein the proximity sensor is selected from an ultrasonic sensor and an LED (Light Emitting Diode) time-of-flight range finder.

4. The method of claim 1 , further comprising:
determining, based upon a reading of an orientation sensor of the hazard detector, that an instant spatial orientation of the hazard detector is unsuitable for one or more features of the hazard detector to operate as intended; and
in response to the determining, outputting the particular notification to indicate that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards.

5. The method of claim 1 , further comprising:
determining that an instant wireless signal strength detected by the hazard detector is within an unacceptable range; and
in response to the determining, outputting the particular notification to indicate that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards.

6. The method of claim 1 , further comprising:
determining that a particular hazard detection feature of the hazard detector is operating within an unacceptable range due to instant readings being outside of an acceptable range; and
in response to the determining, outputting the particular notification to indicate that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards.

7. The method of claim 6 , wherein the particular hazard detection feature is selected from a carbon monoxide detection feature, a smoke detection feature, an ALS (Ambient Light Sensor) detection feature, and an ambient temperature detection feature.

8. The method of claim 1 , further comprising:
outputting at least one of an audible notification and a visual notification during installation at the particular location when it is determined that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards.

9. The method of claim 1 , further comprising:
outputting, by the hazard detector, another particular notification during installation at the particular location when it is determined that the instant placement of the hazard detector would permit the hazard detector to operate within specification to detect one or more hazards, based upon readings of at least one component of the hazard detector.

10. The method of claim 9 , further comprising:
outputting at least one of an audible notification and a visual notification during installation at the particular location when it is determined that the instant placement of the hazard detector would permit the hazard detector to operate within specification to detect one or more hazards.

11. A hazard detector, comprising:
at least one component to test during installation of the hazard detector at a particular location whether an instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards; and
a processing system, in operative communication with the at least one component, that:
determines, based upon readings of the at least one component, whether an instant placement of the hazard detector during installation thereof would prevent the hazard detector from operating within specification to detect one or more hazards; and
when it is determined that the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards, causes a notification alert to be output to guide a user during installation of the hazard detector to a suitable installation location for the hazard detector.

12. The hazard detector of claim 11 , wherein the at least one component comprises an ultrasound sensor that determines a distance of the hazard detector from at least one surface in proximity to the hazard detector based on reflections of interrogating ultrasonic waves, wherein the notification alert is output by the hazard detector when it is determined that the distance of the hazard detector from the at least one surface is less than or equal to a predetermined and regulated distance.

13. The hazard detector of claim 11 , wherein the at least one component comprises a time-of-flight LED (Light Emitting Diode) component that determines a distance of the hazard detector from at least one surface in proximity to the hazard detector based on reflections of interrogating optical waves, wherein the notification alert is output by the hazard detector when it is determined that the distance of the hazard detector from the at least one surface is less than or equal to a predetermined and regulated distance.

14. The hazard detector of claim 11 , wherein the at least one component comprises a video camera that determines a distance of the hazard detector from at least one surface in proximity to the hazard detector based on image segmentation and surface recognition, wherein the notification alert is output by the hazard detector when it is determined that the distance of the hazard detector from the at least one surface is less than or equal to a predetermined and regulated distance.

15. The hazard detector of claim 11 , wherein the at least one component comprises a GPS (Global Positioning Sensor) component that determines whether the particular location is of a type prohibitive for installation of the hazard detector, wherein the notification alert is output by the hazard detector when it is determined that the particular location is a prohibited type for installation of the hazard detector.

16. The hazard detector of claim 11 , further comprising a communication interface that receives from a camera system external to the hazard detector an indication of whether the instant placement of the hazard detector would prevent the hazard detector from operating within specification to detect one or more hazards, wherein the notification alert is output by the hazard detector when it
