Various examples described herein provide for causing operation of a cooling system of a computing device to be adjusted (e.g., reduced or disabled) during at least a portion of a backup operation, where data is copied from volatile memory of the computing device to non-volatile memory of the computing device. Some examples can be implemented with respect to a type 10 (T10) non-volatile dynamic inline memory module (NVDIMM) configuration.

Disclosed are techniques for saving power in a Universal Serial Bus (USB) repeater/re-timer between a USB host and a peripheral device by intercepting packets received from the host to predict the direction of data traffic to selectively turn off/on circuitry of a peripheral port used to receive packets from the peripheral device. If a host port determines that the host is sending a start-of-frame (SOF) packet, the direction of data flow is from the host to the peripheral device, and the repeater may turn off the peripheral port such as squelch circuitry. If the host port determines that the host is sending a non-SOF packet, such as an address token that precedes a host-to-peripheral-device data transfer or a peripheral-device-to-host data transfer, the direction of data flow is anticipated to be from the peripheral device to the host, and the repeater may re-enable the deactivated circuitry of the peripheral port.

A system includes a fingerprint sensor, an application processor, and an auxiliary processor. The application processor is operable to arm the fingerprint sensor prior to the application processor entering a low power or sleep mode. The auxiliary processor is to receive a state output from the fingerprint sensor. The state output is to cause activation of one or more functions of the auxiliary processor upon fingerprint authentication while leaving the application processor in the low power or sleep mode.

Systems and methods are provided for optimizing battery life in an electronic device. The device is configured to make periodic assessments of battery capacity by measuring the DC resistance value of the battery cell during the execution of a power-consuming operation. If the measured DC resistance value reaches a threshold level, the device can initiate a power-saving mode in which an operating parameter of the device is adjusted to decrease power consumption.

Various systems and methods for adapting a computer based on user attentiveness are described herein. A system for attention-based gesture recognition includes processing circuitry to: access an image of a user, the user proximate to a computing device; determine, based on the image, whether user is attentive to the computing device; and selectively enable or disable a function of the computing device depending on whether the user is attentive.

The disclosure describes artificial reality (AR) systems and techniques that enable hierarchical power management of multiple devices within a multi-device AR system. For example, a multi-device AR system includes a device comprising one of a peripheral device configured to generate artificial reality content for display or a head-mounted display unit (HMD) configured to output artificial reality content. The device comprises a System on a Chip (SoC) that includes a host subsystem and plurality of subsystems. Each subsystem includes a child energy processing unit configured to manage power states for the subsystem. The host subsystem includes a parent energy processing unit configured to direct power management of each of the child energy processing units of the plurality of subsystems.

A wireless peripheral mode is provided by a host system that communicates to a WiFi infrastructure and, utilizing the same WiFi RF subsystem, also communicates to peripherals. The host system may employ additional RF channels for communicating with high bandwidth peripherals, such as display devices, where high levels of QoS may be managed locally. The host system may be a conventional desktop computer system, a notebook computer system, a multi-media access point, a cell phone, a game machine, a portable game machine, a Personal Digital Assistant (PDA), a smart phone or any other type of device that benefits from accessing both a WiFi infrastructure and local peripherals.

An electronic device includes a hinge structure; a first housing; second housing foldably connected to the hinge structure and configured to be foldable with respect to the first housing; a first display disposed from at least a part of a first surface to at least a part of a third surface; a second display; a first sensor configured to collect sensor data related to movement of the first housing; a second sensor configured to collect sensor data related to movement of the second housing; and a processor operatively connected with the first display, the second display, the first sensor, and the second sensor. The processor is configured to: identify a folding angle between the first housing and the second housing by using the first sensor and the second sensor, select the second display based on the folding angle between the first housing and the second housing being in a first range, determine a display direction of a content, based on the sensor data obtained by the second sensor, and control the second display to display the content, based on the display direction of the content.

A technique for dynamically adjusting power use of an input/output (I/O) interface of an electronic device is provided. The electronic device includes an input/output (I/O) interface that facilitates electronic communications with a receiving electronic device, at a particular transmission rate that is dynamically changeable by the electronic device. Transmission power and transmission rate adjustment circuitry determines whether a step-down in a transmission power used for signal transmission at the particular transmission rate is desirable. When desirable, the transmission power is dynamically adjusted down one step, such that less power is used by the I/O interface during the electronic communications.

A computer system displays a respective user interface corresponding to a restricted state. Displaying a first user interface that corresponds to the restricted state when a current time is outside a first preset time period, and displaying a second user interface that corresponds to the restricted state when the current time is within the first preset time period. While displaying the respective user interface, detecting a first input. In response to detecting the first input that meets first criteria, directed to the first user interface, replacing display of the first user interface with a third user interface different from the first and second user interfaces. In response to detecting the first input that meets second criteria different from the first criteria, directed to the second user interface, replacing display of the second user interface with display of the first user interface.
