Methods and systems for image clustering are described, and include first receiving a plurality of images from a video of a game. Next, determining a first feature vector of a first player from the plurality of images by inputting the plurality of images to an artificial intelligence (AI)-based process. Next, dividing the plurality of images into a first subset of images and a second subset of images based on the first feature vector. Next, receiving a first identifier tagging the first player in a first image of the first subset. Finally, identifying a second player in a second image in the second subset by propagating the first identifier of the first subset, based on a distance measure associated with the first feature vector from the artificial intelligence (AI)-based process. Running on a mobile computing device, the method allows multiplayer tagging to be easily performed in almost any environment.

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.

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.

Accessibility aids for users of electronic devices

A method may include operating a switching circuit in an on state and an off state to actuate a flow of electrical power through a load when switched to the on state; monitoring an electrical property associated with the switching circuit; receiving an enable signal from a processor to power the load; providing a drive signal to the switching circuit to switch to the on state and power the load; determining if an electrical anomaly is present based on the monitored electrical properties; causing the switching circuit to switch to the off state if an electrical anomaly is detected; providing a fault signal to the processor; determining while the switching circuit is off, if the electrical anomaly has been corrected; and after the anomaly has been corrected, causing the switching circuit to switch to the on state.

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.
