Abstract
Hazard detection systems and methods according to embodiments described herein are operative to enable a user to interface with the hazard detection system by performing a touchless gesture. The touchless gesture can be performed in a vicinity of the hazard detection system without requiring physical access to the hazard detection system. This enables the user to interact with the hazard detection system even if it is out of reach. The hazard detection system can detect gestures and perform an appropriate action responsive to the detected gesture. In one embodiment, the hazard detection system can silence its audible alarm or preemptively turn off its audible alarm in response to a detected gesture. Gestures can be detected using one or more ultrasonic sensors, or gestures can be detected using a motion detector in combination with one or more ultrasonic sensors.

18. A hazard detection system, comprising:
-
at least one hazard detection sensor; alarm generation circuitry operative to sound an audible alarm; a speaker for playing back a recorded message; gesture detection circuitry operative to detect a gesture event; and control circuitry operative to; playback a recorded message through the speaker, the recorded message including instructions for a user to perform the gesture event in a vicinity of the hazard detection system; process data acquired from the gesture circuitry to determine whether the gesture event has been performed; and change a state of the hazard detection system in response to a determination that the gesture event has been performed. - View Dependent Claims (19, 20, 21, 22, 23)

24. A method for processing a gesture to alter a state of an audible alarm, the method implemented by a hazard detection system, the method comprising:
-
activating alarm generation circuitry to emit an audible alarm; monitoring at least one ultrasonic detection field for presence of at least one object; determining whether the at least one object is moving in accordance with a gesture while the at least one object is present in the at least one ultrasonic detection field; and deactivating the alarm generation circuitry to cease emitting the audible alarm when it is determined that the at least one object is moving in accordance with the gesture while the at least one object is present in the at least one ultrasonic detection field. - View Dependent Claims (25, 26, 27, 28, 29)

30. A hazard detection system, comprising:
-
alarm generation circuitry for generating an audible alarm in response to a detected hazard event; at least one ultrasonic sensor, each ultrasonic sensor having a detection field for monitoring presence of at least one object; and control circuitry operative to; instruct the alarm generation circuitry to emit the audible alarm during the detected hazard event; and receive sensor data from at least one sensor, including the at least one ultrasonic sensor; process the sensor data to determine whether a hush gesture has been captured by the received sensor data; and instruct the alarm generation circuitry to at least temporarily cease emitting the audible alarm when the hush gesture has been captured by the received sensor data. - View Dependent Claims (31, 32, 33, 34, 35, 36)

37. A hazard detection system, comprising:
-
at least one hazard detection sensor operative to monitor an environment in a vicinity of the hazard detection system, wherein the hazard detection system operates according to one of an idle mode, a pre-alarm mode, and an alarm mode; alarm generation circuitry operative to sound an audible alarm in the alarm mode; a speaker operative to playback at least one recorded message; gesture detection circuitry operative to monitor the vicinity for a gesture; and control circuitry operative to; select one of the idle, pre-alarm, and alarm modes based on data acquired from the at least one hazard detection sensor; and wherein, when the hazard detection system is in the pre-alarm mode, the control circuitry is further operative to; playback a recorded message through the speaker; detect whether the gesture is monitored by the gesture detection circuitry; and preemptively disable the alarm generation circuitry when the gesture is detected and the data acquired from the at least one hazard detection sensor is sufficient to change the system operation from the pre-alarm mode to the alarm mode. - View Dependent Claims (38, 39, 40, 41, 42, 43)
