Abstract:
Various arrangements for using multiple wavelengths of electromagnetic radiation to detect smoke by a smoke detector are present. Multiple modes of the smoke detector may be used in which a first wavelength of electromagnetic radiation is emitted into a smoke chamber while a second electromagnetic radiation emitter is disabled, a period of time is waited, and a second wavelength of electromagnetic radiation is emitted into the smoke chamber while the first emitter is disabled. Depending on the mode of the smoke detector, the period of wait time may be varied.
Abstract:
A method for establishing a pairing between a smart-home device and an online account may include instantiating an application on a computing device and receiving a first code from a central server. The application may receive a second code from printed material associated with the smart-home device. The smart-home device may broadcast a first communication protocol, and the application may join the first mutation protocol. The application can be authenticated by the smart-home device using the second code, and the application can receive an identity of a second communication protocol from a user. The application can then transmit the identity of the second communication protocol to the smart-home device. The smart-home device can use the second mutation protocol to access the Internet and transmit the first code to the central server, where the central server can use the first code in completing the pairing process.
Abstract:
This application is directed to a physical assembly including a magnet mount for physically receiving a physical module that includes a housing having a rear surface of a first shape. The magnet mount includes a first surface, a second surface and a magnetic material. The first surface is configured to attach to a mounting surface. The second surface has a second shape that is substantially complementary to the first shape, and is configured to engage the rear surface of the housing of the physical module. The magnetic material is disposed between the first and second surfaces and configured to magnetically couple to a magnetic material of the physical module. When the physical module is magnetically coupled to the magnet mount, an adjustable union between the magnet mount and the physical module is formed permitting adjustment of an angle of orientation of the physical module with respect to the magnet mount.

Abstract:
A hazard detector includes a chassis configured to house components of the hazard detector. The chassis includes a front defining a central aperture. The front has a domed contour such that an outer edge of an inner portion extends beyond an outer periphery of the front. The inner surface tapers from the outer edge toward the inner portion. The detector includes a mesh formed to the contour of the front so the mesh is flat against the front. The mesh defines an aperture corresponding to the central aperture. The detector includes a grille secured to the chassis that defines an aperture corresponding to the central aperture and defines openings positioned along the grille. An inner surface of the grille includes a contour corresponding to the contour of the front so the mesh is flat against the inner surface. The mesh is positioned between the grille and the chassis.

Abstract:
Various embodiments of a smoke chamber for a smoke detector are presented. Such a smoke chamber may include a housing, having a first portion and a second portion. The first portion may be through which an electromagnetic sensor and two or more electromagnetic emitters interact with an airspace within the housing. The second portion may have an airflow surface that at least partially defines a curved airflow path between the airspace within the housing and an external environment. The curved airflow path may curve radially outward.
