Visual and auditory user notification methods for smart-home hazard detector
First Claim
1. A hazard detector for providing a pre-alarm of a hazardous condition, the hazard detector comprising:
- a hazard sensor that measures a hazard level, the hazard sensor measuring at least one of smoke and carbon monoxide (CO);
a storage module configured to store a pre-alarm threshold, the pre-alarm threshold being less than an emergency threshold;
a light source that generates light;
a speaker that generates audible sound;
a user interface module in communication with a processing module, the user interface module being configured to receive user input;
a horn that generates an audible alarm at a higher volume than the speaker; and
the processing module in communication with the hazard sensor, the storage module, the light source, the speaker, and the horn, the processing module being configured to;
compare the measured hazard level with the pre-alarm threshold,compare the measured hazard level with the emergency threshold,determine that the measured hazard level is greater than the pre-alarm threshold and that the measured hazard level is less than the emergency threshold,generate audible pre-alarm speech via the speaker in response to determining that the measured hazard level is greater than the pre-alarm threshold and less than the emergency threshold,activate the light source in response to determining that the measured hazard level is greater than the pre-alarm threshold and less than the emergency threshold,receive the user input from the user interface module, andstop generating the audible pre-alarm speech in response to receiving the user input.

Abstract
Hazard detector for providing a pre-alarm of a developing hazardous condition can include a detection module that detects a hazard level of smoke or carbon monoxide, a light source that generates light, a speaker that generates an audible sound, a horn that generates an audible alarm that a higher volume than the speaker, and a processing module. The processing module can receive the detected hazard level and compare it with the pre-alarm threshold and the emergency threshold. The processing module can determine that the hazard level is greater than the pre-alarm threshold and less than the emergency threshold and cause an audible pre-alarm speech to be generated via the speaker that warns of the developing hazardous condition.

12. A method for providing a pre-alarm notification, the method comprising:
-
detecting a first hazard level, the first hazard level indicating an amount of at least one of smoke and carbon monoxide (CO) present at a hazard detector; comparing the first hazard level with an emergency threshold; determining that the first hazard level is less than the emergency threshold; comparing the first hazard level with a pre-alarm threshold, the pre-alarm threshold being less than the emergency threshold; determining that the first hazard level is greater than the pre-alarm threshold; activating a light source that generates light in response to determining that the first hazard level is greater than the pre-alarm threshold and less than the emergency threshold; outputting, via a speaker, an audible pre-alarm speech in response to determining that the first hazard level is greater than the pre-alarm threshold and less than the emergency threshold, the audible pre-alarm speech including content that warns of the detected first hazard level; receiving user input via a user interface module of the hazard detector; and stopping generation of the audible pre-alarm speech in response to receiving the user input. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer-readable medium, having instructions stored therein, which when executed cause a hazard detector to perform a set of operations comprising:
-
detecting a hazard level that indicates an amount of at least one of smoke and carbon monoxide (CO); comparing the hazard level with an emergency threshold; determining that the hazard level is less than the emergency threshold; comparing the hazard level with a pre-alarm threshold, the pre-alarm threshold being less than the emergency threshold; determining that the hazard level is greater than the pre-alarm threshold; activating a light source; causing a speaker to output audible pre-alarm speech in response to determining that the hazard level is greater than the pre-alarm threshold and less than the emergency threshold; receiving user input via a user interface module of the hazard detector; and ceasing generation of the audible pre-alarm speech in response to receiving the user input.
