    Abstract: A host device establishes a wireless communication link with a client device, and implements a wired communication standard on the link to transfer a first data stream. To increase data throughput while complying with the standard, the host device replaces synchronizing information in a packet to be sent during a first synchronizing frame with configuration information indicating that packet exchange data of a second data stream is to be sent or received during a second synchronizing frame. The host device sends or receives the packet exchange data of the second data stream to or from the client device during the second synchronizing frame via the wireless communication link. The host device may send or receive the packet exchange data of the second data stream during delays or idle periods between sending and/or receiving packets of the first data stream via the wireless communication link according to the wired communication standard.

    Abstract: A first device may communicate via a first wireless interface (WI) and a second WI, with the second WI operating at a relatively higher power level than the first WI. The first device may receive a scan notification corresponding to wireless scanning performed by a second device. The first device may subsequently perform wireless scanning using the second WI in response to the scan notification indicating that the first device is within effective communication range of a third device. The first device may receive the scan notification over a wireless connection established between the first device and the second device using the first WI. The first device may transmit filter information to the second device, the filter information indicating when, and for which scans the first device is to receive scan notifications. The first device may also activate the second WI and use the second WI to perform ranging and/or control operations associated with the third device.

    Abstract: A display may have an array of organic light-emitting diode display pixels. Each display pixel may include a drive transistor coupled in series with one or more emission transistors and a respective organic light-emitting diode (OLED). A semiconducting-oxide transistor may be coupled between a drain terminal and a gate terminal of the drive transistor to help reduce leakage during low-refresh-rate display operations. To compensate for variations in the threshold voltage of the semiconducting-oxide transistor, the magnitude of a high voltage level of a scan control signal provided to the gate terminal of the semiconducting-oxide transistor may be adjusted. Sensing circuitry may be used to sense a display current while displaying a calibration image. The sensed display current may be compared to an expected display current associated with the calibration image. Processing circuitry may update the high voltage level based on the actual display current compared to the expected display current.
