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: In an example, a wireless client station detects a first signal emitted by a first wireless access point and a second signal emitted by a second wireless access point. The wireless client station extracts a first set of data indicative of the signal strength and network congestion of the first wireless access point and a second set of data indicative of the signal strength and network congestion of the second wireless access point. The wireless client station then computes a first performance metric of first wireless access point, based on the first set of data, and a second performance metric of the second wireless access point, based on the second set of data. The wireless client station determines that the first performance metric is greater than the second performance metric and initiates a connection to the first wireless access point in response.

Abstract: A technique includes identifying a cellular communication frequency band and a wireless local area network communication channel being used by a wireless station. Based on the identified cellular communication frequency band and wireless local area network communication channel, assignment of the wireless local area network communication channel is regulated to inhibit interference due to the concurrent use of the cellular communication frequency band and the wireless local area network communication channel. The regulation of the assignment includes using the wireless station to determine whether to reassign the wireless local area network communication channel.

Abstract: In one example, a sink device includes a display unit, a mirroring unit to mirror a first display screen of a first source device and a second display screen of a second source device at the display unit via a wireless network, a communication interface unit to receive a first input indicating a selection of the first display screen and interpret the first input as a control command to dynamically establish a peer-to-peer connection between the sink device and the first source device via a short-range wireless network, and a control unit to control media content associated with the first source device via the short-range wireless network based on a first human interface device (HID) command received at the sink device.

Abstract: In examples, a non-transitory computer-readable medium stores machine-readable instructions which, when executed by a processor of an electronic device, cause the processor to receive a packet, determine a priority level of the packet, calculate a delay time based on the priority level, and transmit the packet over a network upon an expiration of the delay time.

Abstract: In one example, an input pen to control an operation of a display is described, which may include a sensor to detect an input pen gesture, a communication interface to establish a connection with the display, and a controller to transmit a control signal corresponding to the detected input pen gesture to the display via the communication interface. The control signal may be used to retrieve a gesture command to manipulate data on the display.

Abstract: Screen casting on between two devices is described. In an example implementation, a communication link is established by a first device with a second device for casting a screen of the second device on the first device. Upon establishing the communication link, a command message is sent by the first device to the second device to set a backlight of the screen of the second device based on user backlight settings. When no user activity is detected on the second device for a specific time period, a request message is received by the first device from the second device, indicating switching the backlight of the screen of the second device to power-saving backlight settings. In response to the request message, a command message is sent by the first device to the second device to set the backlight of the screen of the second device based on the power-saving backlight settings.

Abstract: An example implementation relates to identifying a preferred transfer mode available for communicating with a target device, from among a plurality of priority-ordered transfer modes that includes a peer-to-peer mode, an FTP mode, and an HTTP mode. A data communication can be performed with the target device using the preferred transfer mode.

Abstract: Wireless charging of electronic devices is described. In an example implementation, electromagnetic current is induced in a first set of coils of an electronic device upon coupling of the first set of coils with a second set of coils of a charging base, and a rechargeable battery of the electronic device is wirelessly charged based on the induced electromagnetic current. A coil from amongst the first set is determined to send a message to the charging base to disable a coil of the second set which overlaps with the determined coil of the first set.
