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.

Screen casting

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.

Selection of wireless access points based on signal strength and network congestion

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.

Media content control of source devices on sink devices

An example electronic device includes a first housing including, a first display, a first antenna, a second antenna, and a first rotational motion sensor. The electronic device also includes a hinge including a bend sensor. The electronic device further includes a second housing rotatable coupled to the first housing via the hinge. The second housing includes a second display, a third antenna, a fourth antenna, and a second rotational motion sensor. The electronic device further includes a communication device to select two of the first antenna, the second antenna, the third antenna, and the fourth antenna based on the first rotational motion sensor, the second rotational motion sensor, and the bend sensor. The communication device is also to transmit and receive data via each of the two selected antennas.

Antennas selection based on sensors

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.

Mirroring of screens

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.

Regulating assignment of a wireless local area network communication channel

Examples of wireless charging of a computing system are described herein. In an example, a charging notification from a power transmit unit (PTU) in a power transfer field of the computing system may be received. In response to receiving the charging notification, it may be ascertained whether a near field communication (NFC) component of the computing system is in an active state for data communication. When the NFC component is in the active state, an input may be provided to switch the active state of the NFC component to an inactive state for disabling data communication through the NFC component.

Wireless charging

Example systems relate to wireless head-mounted devices. A wireless head-mounted device may include high-throughput performance miming at millimeter wave band receiving hardware to receive a transmission from corresponding high-powered transmitting hardware included in a computing device. The transmission may include audio, visual, or video data. The wireless head-mounted device may further include a plurality of sensors to collect sensor data. The wireless head-mounted device may further include low-powered transmitting hardware to transmit at least the sensor data collected by the sensors to corresponding low-powered receiving software included in the computing device.

Wireless head-mounted device

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.

Input pen gesture-based display control

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.

Data communication using a preferred transfer mode

In one implementation, radio power mode switching includes comparing a time zone associated with a current location of a client device with a country code associated with a current location of an access point, where the client device is connected to the access point, and switching a first radio power mode of the client device to a second radio power mode of the client device based on the comparison of the time zone and the country code.
