US 11,641,108 B2 · Systems, apparatus, and methods for power management

Abstract

Systems, apparatus, and methods for controlling power modes in electronic devices are provided. A system may include an electronic device and an input device that sends power mode selection information via a network to a power mode selection receiving component in the electronic device. The electronic device includes a first power component that powers a first component, and a switching component that controls the first power component. The electronic device may include a second power component that powers a second component. The switching component may control the second power component. The power mode selection receiving component and the switching component may be powered independently of the first and the second component. If the power mode selection information indicates an off mode, the electronic device may provide power to the power mode selection receiving component and the switching component and not to the first and the second component.

Dependent claims

An electronic device comprising:

power supply circuitry to connect to an external alternating current (AC) power supply and to generate therefrom direct current (DC) power;
processing circuitry to provide at least one of audio or video information for output by the electronic device, in a power-on mode, dependent on the DC power, wherein processing circuitry comprises first circuitry and second circuitry;
power control circuitry to selectively depower the first circuitry in a power-off mode as well as in a low-power mode, and to selectively depower the second circuitry in the power-off mode but not the low-power mode;
and
receiver circuitry to receive an external input;
wherein the electronic device is to transition from a first one of the power-on mode, the low-power mode and the power-off mode, to a second one of the power-on mode, the low-power mode and the power-off mode, in response to receipt of the external input.

3 more elements

A method of operation in an electronic device having power supply circuitry, processing circuitry, power control circuitry and receiver circuitry, the method comprising:

receiving power from an external alternating current (AC) power supply and generating therefrom direct current (DC) power;
with the processing circuitry, providing at least one of audio or video information for output by the electronic device, in a power-on mode, dependent on the DC power, wherein processing circuitry comprises first circuitry and second circuitry;
controlling the power control circuitry so as to selectively depower each of the first circuitry and the second circuitry;
and
receiving an external input with the receiver circuitry;
wherein the method further comprises causing the electronic device to transition from a first one of the power-on mode, the low-power mode and the power-off mode, to a second one of the power-on mode, the low-power mode and the power-off mode, in response to the receiving of the external input.
