Abstract: Examples of mirroring a screen between two devices include establishing a communication link by a sink device with a source device to mirror a screen of the source device on the sink device. Upon determining a same orientation of the source device for a specific time period, a display OFF command is sent to the source device. The display OFF command is indicative of turning OFF a backlight of the screen of the source device. Further, an event notification may be received by the sink device upon occurrence of an event at the source device. The event includes an incoming communication or a change in the orientation of the source device. In addition, in response to the event notification, a switch command is sent to the source device to pause the signal stream and to turn ON the backlight of the screen of the source device.

Abstract: Example implementations relate to device management. In some examples, a system may include a computing device comprising executable instructions to authenticate the computing device to a first wireless network, implementing a first level of security, while in an active state. A system may include a computing device comprising executable instructions to disconnect from the first wireless network responsive to entering a sleep state. A system may include a computing device comprising executable instructions to provide, from a basic input/output system (BIOS) of the computing device, a wireless parameter for a second wireless network implementing a second level of security. A system may include a computing device comprising executable instructions to connect to the second wireless network while in the sleep state.

Abstract: Example implementations relate to transmission power adjustments. For example, a system for transmission power adjustments may comprise a processing resource and a memory resource storing readable instructions to cause the processing resource to determine a network type for a wireless connection from a plurality of network types, and alter a transmission power for a transmitter based on the network type for the wireless connection.

Abstract: In one example, a computing device is disclosed, which includes a storage unit, a communication interface, and an authentication unit. The storage unit may store communication information corresponding to a wireless device. The communication information may include information used to establish communication between the wireless device and a user device. Further, the communication interface may receive a request to establish communication with the wireless device from the user device via a short-range wireless communication. Furthermore, the authentication unit may authenticate an access credential associated with the user device to access the wireless device and enable the storage unit to transmit the communication information associated with the wireless device to the user device upon successful authentication. The communication information is set up on the user device to establish communication with the wireless device.

Abstract: In some examples, a non-transitory computer-readable medium stores machine-readable instructions which, when executed by a controller of an electronic device, cause the controller to perform an assistive depth of field analysis. Performing the assistive depth analysis causes the controller to receive images from an image sensor, determine, via artificial intelligence (AI) processing, a depth of field of the images, and generate a signal representing consecutive changes in the depth of field of the images with respect to a first of the images.

Abstract: Example implementations relate to virtual reality buffering. In some examples, a wireless system may include a wearable display and instructions executable by a processor. The instructions may be executable by a processor to assign a first portion of a total bandwidth, associated with wirelessly delivering a virtual reality (VR) video stream to the wearable display, to instantiate of an image of an active region of the VR video stream on the wearable display. The instructions may be executable by a processor to assign a second portion of the total bandwidth to buffering a peripheral region of the video stream.
