  • Publication number: 20220224157
    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.

  • Patent number: 11314313
    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.

  • Patent number: 11228955
    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.

  • Publication number: 20210216405
    Abstract: Examples associated with networking component repair are described. One example includes detecting an error associated with a networking component of a device. The networking component may be disabled and enabled to attempt to remedy the error associated with the networking component. When the disabling and enabling actions fail to remedy the error and the error is associated with a driver for controlling the networking device, a setting associated with the networking component may be repaired. The networking component may be controlled to connect to a known available network using historical connection settings.

  • Patent number: 10901679
    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.

  • Patent number: 10693320
    Abstract: 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.

  • Patent number: 10694390
    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.
