Patent number: 10732651Abstract: 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 an 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.Type: GrantFiled: December 26, 2017Date of Patent: August 4, 2020Assignee: Google LLCInventors: Andrea Mucignat, Oliver Steele, Senthilvasan Supramaniam, Osborne Hardison, Richard J.

Patent number: 10444836Abstract: A simplified UI mode is provided for computing devices, where complex user interface elements are replaced with simpler ones. In one embodiment, content, functions, and/or other selectable items on the home screen or panel(s) of the device are assembled into a one-dimensional list. In some cases, the simplified UI mode can be configured to receive a parsing gesture (e.g., downward drag gesture or a three-finger tap) that causes an item of the list to be aurally presented to the user, and a selection gesture (e.g., release of the drag gesture or a two-finger tap) to select the last aurally presented item. The simplified UI mode may be used in conjunction with a screen protector configured with tactile aid(s) configured to facilitate use of the device by a vision-impaired user. In one case, one of the tactile aids of the screen protector indicates how to activate the simplified user interface mode.Type: GrantFiled: June 7, 2013Date of Patent: October 15, 2019Assignee: Nook Digital, LLCInventor: Ian C.

Patent number: 10191727Abstract: A thermostat is described that includes a rechargeable battery, a graphical user interface and a wireless network communication capabilities. During installation, in cases where the rechargeable battery is below a first threshold, the installation procedure is limited so as to avoid energy intensive installation steps which may not be supported by the low battery level. An example of an installation step that is avoided due to low battery level is set up of wireless communication. According to some embodiments, if the battery level is very low during initial installation, the installation process is halted while the battery is charged. An indication such as a flashing LED may be displayed so as to indicate to the user that the battery is being charged.Type: GrantFiled: October 8, 2015Date of Patent: January 29, 2019Assignee: Google LLCInventors: Daniel Adam Warren, Hugo Fiennes, Jonathan Alan Dutra, David Bell, Anthony Michael Fadell, Matthew Lee Rogers, Ian C.

Patent number: 9851699Abstract: Systems and methods for interfacing a hazard detection device with a control panel system via a dongle are provided. The dongle may be configured to alternate between drawing first and second amounts of power from the control panel system in response to the hazard detection device alternating between operating in a normal mode when no hazard is detected and an alarm mode when a hazard is detected. The hazard detection device may operate independently of any characteristics of the control panel system. For example, the hazard detection device may operate without drawing any power from the control panel system. Therefore, the dongle may allow for various types of hazard detection devices to interface with a common two-line power control system.Type: GrantFiled: July 17, 2014Date of Patent: December 26, 2017Assignee: GOOGLE LLCInventors: Anthony Michael Fadell, Scott Mullins, Brian Jonathan Conner, Ian C.
