Abstract:
According to one embodiment, a hazard detector includes a front casing coupled with a back plate to define a housing having an interior region. The hazard detector also includes a passive infrared sensor device that is disposed within the interior region and that is positioned to face a room within which the hazard detector is positioned so as to detect objects within the room. The hazard detector additionally includes a Fresnel lensing component that is disposed on an exterior of the front casing and that is positioned in front of the passive infrared sensor device to direct infrared radiation onto the passive infrared sensor device. The Fresnel lensing component is configured to be inwardly pushable by a user to cause contact with a switch positioned therebehind so that input is provided to the hazard detector by the user.
Abstract:
According to one embodiment, a multi-sensing hazard detector for detecting potential dangers may include a back plate and a front casing that is coupled with the back plate to define a housing. A circuit board and a plurality of components may be positioned within the housing. The circuit board may be communicatively coupled with the components. The components may include, among other components, an alarm device, an occupancy sensor, and a smoke chamber. The alarm device may be activatable upon the detection of a potential hazard to warn an occupant of a potential danger, the occupancy sensor may be configured to detect the presence and/or movement of objects external to the hazard detector, and the smoke chamber may be configured to detect the presence of smoke to cause a triggering of the alarm device. The housing may comprise a volume of less than 1024 cubic centimeters.
Abstract:
Various arrangements for light distribution incorporated as part of a device are presented. A circular light guide may be used that receives light from a plurality of light emitters that can be arranged in a circular pattern. A conical reflector may be used and may be positioned to reflect light emitted from the circular light guide onto an exterior of a case of the device. The conical reflector may reflect light such that light is reflected by the exterior of the case in the shape of a halo into an ambient environment of the device.
Abstract:
Embodiments disclosed herein provide a detector unit and sensor chamber with matter retention member and method for making the same. In one embodiment, a smoke chamber can include a detection circuitry member having a surface, a particle trapping member mounted to the surface, and a chamber coupled to the detection circuitry member. The chamber can include a planar member, and several baffles extending away from the planar member in the direction towards the detection circuitry member and disposed around a periphery of the planar member, wherein a distal end of each baffle interfaces with the particle trapping member.

Abstract:
Various arrangements of smart devices are presented. Such a smart device may include a case, a wireless interface, a light sensor that detects an ambient brightness level of an ambient environment of the smart device, a motion sensor that detects motion of a user in the ambient environment of the smart device, a light that is capable of outputting light into the ambient environment of the smart device, and a processing system. The processing system may cause the light to illuminate based on: the message indicating that the lighting feature has been activated; the ambient brightness level being below the threshold brightness value; and the user moving in the ambient environment of the smart device.
Abstract:
According to one embodiment, an access door for a hazard detector includes a release member that releasably secures the access door in a closed position over a battery compartment of the hazard detector. The release member allows the access door to be pivoted open and closed relative to the battery compartment and hazard detector. The access door also includes a first hinge member and a second hinge member. The first hinge member enables the access door to pivot along a first pivot path and by a first pivot amount and the second hinge member enables the access door to pivot along a second pivot path and by a second pivot amount. A cumulative total of the first pivot amount and the second pivot amount is substantially greater than either pivot amount alone.
Abstract:
An electrical connector that may include a socket body and that includes four lateral walls, a rear wall, a catch feature and a catch support. The lateral walls may adjoin one another and the rear wall. The catch support may adjoin two of the lateral walls along edges of the catch support to define a catch cavity and a plug cavity on opposing sides of the catch support. A first side of the rear wall may face the plug cavity and a second side bounds a rear surface of the socket body. The catch feature may couple with the catch support. Electrical pins may pass through the rear wall of the socket body such that one end of each of the pins is within the plug cavity, and an opposing end of each of the pins extends away from the rear surface of the socket body.
Abstract:
Various types of surface mount systems and associated methods are presented. A surface mount plate may be provided that includes a plate having attachment mounting points that allow fasteners to secure the surface mount plate to a surface such that the surface mount plate is mounted in a fixed position on the surface. The surface mount plate may include a circular lip extending around at least a portion of the plate, the circular lip having distributed lip gaps. A sensor housing may include multiple sliders that couple with the circular lip of the surface mount plate when the sliders are aligned and inserted into the plurality of distributed lip gaps of the circular lip and the sensor housing is rotated. The sliders may slide along the lip to allow the housing to be rotated while the sensor housing remains coupled with the surface mount plate.
