Abstract: A smoke detector according to various embodiments discussed herein can use a non-radioactive ionization technique to detect the presence of smoke and/or other particulate matter. A non-radioactive ionizing detector may use a LED such as an ultraviolet light emitting diod in combination with a pair of conductive plates, one of which is coated with a photocatalyst coating. When the light strikes the photocatalyst coating, ions can be generated that change a charge characteristic of the photocatalytic coated plate. The occurrence of an alarm can be detected based on a measured charge magnitude existing between the two plates.

Abstract: Systems and methods for compensating for sensor drift of a smoke sensor are described herein. Sensor drift may be caused by accumulated buildup of dust or other particulates within an enclosure of the smoke sensor. Embodiments described herein can account for sensor drift by adjusting a clear air offset value.

Abstract: Ambient amount of a hazardous condition may be monitored. A mode may be set to a state indicative of the hazardous condition being present in the ambient environment. It may then be determined that the amount of the hazard in the ambient environment has dropped below an alarm criterion. A time period may then be tracked during which the amount of the hazardous condition present in the ambient environment of the hazard detector has remained below the alarm criterion. It may be determined that the time period has reached at least a threshold duration, during such time period the amount of the hazardous condition present in the ambient environment of the hazard detector having remained below the alarm criterion. An indication of the hazardous condition easing may be output in response to the time period being at least the threshold duration.

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 pre-emptively 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.

Abstract: A door lock detection system is disclosed. The system includes a magnet flexibly attached to a strike plate. The strike plate includes an opening. The magnet extends across the opening of the strike plate in a first orientation when a bolt does not extend into the opening of the strike plate. The magnet is configured to be deflected from the first orientation to a second orientation, distinct from the first orientation, in response to the bolt being extended into the opening of the strike plate. The system includes a magnetometer configured to detect one or more magnetic fields of the magnet that is flexibly attached to the strike plate in the first orientation and in the second orientation.

Abstract: Apparatus, systems, methods, and related computer program products for handling temperature variation with optoelectronic components of a hazard detection system are described herein. A power characteristic of an optoelectronic component of the hazard detection system may be used to determine a temperature of an environment of the hazard detection system. A power characteristic of an optoelectronic component of the hazard detection system may be used to determine a smoke condition of an environment of the hazard detection system. Optoelectronic components of the hazard detection system may be optically coupled to determine a smoke condition of an environment of the hazard detection system. Multiple optoelectronics of the hazard detection system may be operative to detect forward scatter and back scatter of one or more types of light to determine a characteristic of a hazard particle.
