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:
Methods and systems facilitate network communications between a wireless network-connected thermostat and a cloud-based management server in a manner that promotes reduced power usage and extended service life of a energy-storage device of the thermostat, while at the same time accomplishing timely data transfer between the thermostat and the cloud-based management server for suitable and time-appropriate control of an HVAC system. The thermostat further comprises powering circuitry configured to: extract electrical power from one or more HVAC control wires in a manner that does not require a “common” wire; supply electrical power for thermostat operation; recharge the energy-storage device (if needed) using any surplus extracted power; and discharge the energy-storage device to assist in supplying electrical power for thermostat operation during intervals in which the extracted power alone is insufficient for thermostat operation.
Abstract:
Various embodiments of hazard detectors are presented. A hazard sensor may be present that detects the presence of a hazardous condition. A light sensor may be present that detects an ambient brightness level. A motion sensor may be present that detects motion of a user. A light may be present that is capable of outputting light. A processing system may receive an indication of the ambient brightness level in the ambient environment of the hazard detector from the light sensor. The processing system may determine that the ambient brightness level is less than a threshold brightness. The processing system may receive information indicative of the user moving in the ambient environment of the hazard detector. The processing system may cause the light to illuminate based on the ambient brightness level being below the threshold brightness and the user moving in the ambient environment of the hazard detector.
Abstract:
According to one embodiment, a casing of a hazard detector includes a body portion and a button portion. The button portion is coupled with the body portion via a plurality of arms. The arms allow the button portion to be axially movable relative to the body portion and also couple the button portion with the body portion so that tabs that extend radially outward from the button portion are positioned under and contact an inwardly facing surface of the body portion. The arms bias the button portion axially outward relative to the body portion so as maintain contact between the tabs and the inwardly facing surface. In this configuration, when the button portion is pressed at a position off-axis from a central axis of the button portion, the button portion pivots about one or more contact points between one or more tabs and the inwardly facing surface.
Abstract:
An occupancy sensing electronic thermostat is described that includes a thermostat body, an electronic display that is viewable by a user in front of the thermostat, a passive infrared sensor for measuring infrared energy and an infrared energy directing element formed integrally with a front surface of the thermostat body. The passive infrared sensor may be positioned behind the infrared energy directing element such that infrared energy is directed thereonto by the infrared energy directing element. The thermostat may also include a temperature sensor and a microprocessor programmed to detect occupancy based on measurements from the passive infrared sensor.
Abstract:
A system including a thermostat user interface for a network-connected thermostat is described. The system includes a thermostat including a frustum-shaped shell body having a circular cross-section and a circular rotatable ring, which is user rotatable for adjusting a setting of the thermostat. The system further includes a client application that is operable on a touch-screen device separate from the thermostat, that displays a graphical representation of a circular dial, that detects a user-input motion proximate the graphical representation, that determines a user-selected setpoint temperature value based on the user-input motion, that displays a numerical representation of the user-selected setpoint temperature value, and that wirelessly transmits to the thermostat data representative of the user-selected setpoint temperature.

In various embodiments, a hazard detector is presented. The hazard detector may include a hazard detection sensor that detects a presence of a type of hazard. The hazard detector may include a light and a light sensor that senses a brightness level in an ambient environment of the hazard detector. The hazard detector may include a processing system configured to receive an indication of the brightness level in the ambient environment of the hazard detector from the light sensor. The processing system may determine the brightness level in the ambient environment of the hazard detector has reached a threshold value. A status check of one or more components of the hazard detector may be performed. The processing system may cause the light to illuminate using a selected illumination state in response to the determining the brightness level in the ambient environment of the hazard detector has reached the threshold value.
Abstract:
A system configured to control a heating, ventilation, or air conditioning (HVAC) system may include an electronic device having a user input interface configured to receive a guest input from a guest user, the guest input including identifying information relating to the guest user. The electronic device may also include a processor configured to determine a level of access of the guest user based on the identifying information and on an input from a primary user. The level of access of the guest user may determine the guest user's ability to adjust a setting of the HVAC system via the electronic device. The processor is also configured to initiate a guest mode of operation where the guest user is able to make a setting adjustment to the HVAC system via the electronic device in place of an established setting adjustment schedule of the primary user in accordance with the determined level of access.
Abstract:
A method for establishing a pairing between a hazard detector and an online account may include instantiating an application on a mobile computing device and receiving a first code from a central server. The application may receive a second code from printed material associated with the hazard detector. The hazard detector may broadcast a Wi-Fi access point, and the application may join the Wi-Fi access point. The application can be authenticated by the hazard detector using the second code, and the application can receive an identity of a home Wi-Fi network from a user. The application can then transmit the identity of the home Wi-Fi network to the hazard detector. The hazard detector can use the home Wi-Fi network 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.
