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:
According to one embodiment, a hazard detector may include a housing having a back plate and a front casing coupled therewith to define an interior space within which various components are contained. The components may include an alarm device and a hazard sensor that is configured to detect a potentially hazardous condition to trigger the alarm device. A cover plate may be coupled with the housing and may face an occupant of a room in which the hazard detector is positioned. The cover plate may include a relatively large population of relatively small openings that are positioned, configured, and dimensioned so that internal components are substantially hidden from view of the occupant while air is allowed to substantially freely flow through the cover plate. A collective area of the openings may be at least 30 % of the total area of the cover plate.
Abstract:
A wall-mountable programmable electronic thermostat for controlling an HVAC system is described. The thermostat includes a circular wall-mountable backplate with a central opening to allow for the passage of HVAC wires for electrical connection to the thermostat. The head unit body is also circular and is removeably mountable to the back plate. A plurality of wedge-shaped wiring terminals are mounted on the backplate for making a tool-free connection to HVAC wires. Each wiring terminal has button that a user can depress while a wire is inserted in a wire hole. The terminals are arranged along one or more circular arcs about the central opening of the backplate such that the wire holes face the central opening and the buttons are located close to the outer periphery of the backplate.

According to one embodiment, a smart home device includes a front casing that is coupleable with a back plate to define a housing having an interior region within which one or more components of the smart home device are contained. The smart home device also includes an occupancy sensor that is disposed within the interior region of the smart home device and a button cap component that is positioned axially in front of the occupancy sensor. The button cap component is pressable by a user to actuate a switch that is disposed axially behind the button cap component. The smart home device further includes a lighting component that is positioned axially behind the button cap component. The lighting component is configured to disperse light circumferentially around the button cap component so as to provide a visual halo effect around the button cap component.

Abstract:
A thermostat compatible with single-HVAC- and dual-HVAC-transformer systems may include a first power return wire connector, a second power return wire connector, and a user-moveable mechanical element that physically blocks wire insertion into the first wire connector when in a first position and physically allows wire insertion into the first wire connector when in a second position. The thermostat may also include a switching circuit that may be in a first configuration when the mechanical element is in the first position, and in a second configuration when the mechanical element is in the second position. The first wire connector may be electrically coupled to the second wire connector in the first configuration, and first wire connector may be electrically isolated from the second wire connector in the second configuration to promote foolproofing against undesired isolation of the first and second wire connectors.
Abstract:
According to one embodiment, a hazard detector may include a back plate and a front casing coupled to the back plate to define a housing having an interior region and an opening through which air flows into the interior region. A circuit board may be coupled to the back plate and have a plurality of components mounted thereon. A smoke chamber may be mid-mounted on the circuit board, mid-mounting being characterized in the smoke chamber extending through a hole formed in the circuit board such that a top surface of the smoke chamber is positioned above a top surface of the circuit board and a bottom surface of the smoke chamber is positioned below a bottom surface of the circuit board, whereby an interior region of the smoke chamber is accessible to smoke from both the top and bottom surfaces of the circuit board.
