A standby power controller (SPC) supplies power to an appliance such as a television, and cuts power to the appliance if the appliance is going unused. The SPC includes first and second sensors, each detecting a type of user activity (such as user presence and remote control usage), and a switch which controls power to the appliance in dependence on the detection status of the first and second sensors, and also preferably in dependence on the prior detection status of at least one of the sensors at one or more points of time in the past.

A display apparatus includes a body; a display provided in the body; a processor provided in the body and configured to control the display to display an image; and a power supply including an adapter configured to be detachable from the body, and a power assembly configured to receive power from the adapter in a non-contact manner and supply the power to at least one of the display and the processor.

The first time a display device is turned on, is turned on after it has been factory reset, or is factory reset, the display device displays a message indicating that in a default and current power mode of the display device, a hardware component of the display device different than display hardware is powered off when the display device enters a low-power state. A user is permitted to have the hardware component remain powered on when the display device enters the low-power state.

A display apparatus with a power supply circuit is provided. The power supply circuit is connected with a light emitting diode (LED) drive circuit, a filter circuit and a feedback circuit in the display apparatus. The power supply circuit includes a fixed-voltage power supply element and a variable-voltage power supply element, and the fixed-voltage power supply element is superposed on the variable-voltage power supply element and configured to supply power to the LED drive circuit in a stepped manner; and a controller is configured to control a voltage of the variable-voltage power supply element according to a variation of the output voltage feedback from the feedback circuit.

Dynamic transcode throttling methods and devices for processing resource management and thermal mitigation in electronic devices such as eyewear devices. An electronic device monitors its temperature and, responsive to the temperature, configures a transcoding service to operate at different rates. A frame delay module is configured to add a delay between read frames prior to the transcoding service. This enables the electronic device to consume less power when temperatures are too high in order to provide thermal mitigation and can be performed without powering down the electronic device.

In general, the present disclosure is directed to an artificial window system that can simulate the user experience of a traditional window in environments where exterior walls are unavailable or other constraints make traditional windows impractical. In an embodiment, an artificial window consistent with the present disclosure includes a window panel, a panel driver, and a camera device. The camera device captures a plurality of image frames representative of an outdoor environment and provides the same to the panel driver. A controller of the panel driver sends the image frames as a video signal to cause the window panel to visually output the same. The window panel may further include light panels, and the controller may extract light characteristics from the captured plurality of image frames to send signals to the light panels to cause the light panels to mimic outdoor lighting conditions.
