Patent number: 11081053Abstract: 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.Type: GrantFiled: February 22, 2019Date of Patent: August 3, 2021Assignee: Apple Inc.Inventors: Jiayi Jin, David A.

Publication number: 20200351781Abstract: 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.Type: ApplicationFiled: May 19, 2020Publication date: November 5, 2020Inventors: Sriram Hariharan, Venkatesh Rajendran, Alon Paycher, Michael Jason Giles

Patent number: 7987304Abstract: Certified Wireless USB 1.0 (CWUSB) defines two different types of association: cable association and numeric association. In the numeric association, the CWUSB host and device use a specific protocol to exchange the security information. At final stage of this information exchange, both host and device need to display a number asking user's feedback. Once this is done, both host and device will be able to generate the connection key as the shared secret for the following secured communication. One problem of this numeric association method is that device needs to be able to display the numbers. For certain class of device that has capability to display an image, there is a natural way to add this function to them. A method for this class of devices is described. Another kind of association, which is not defined in the CWUSB 1.0, is manual association. User needs only to manually type in the Connection Key coming from the CWUSB device.Type: GrantFiled: November 12, 2008Date of Patent: July 26, 2011Assignee: Realtek Semiconductor Corp.Inventors: Turgut Aytur, Frederic Battaglia, Saurabh Garg, Batuhan Okur, Ping-Wen Ong, Venkatesh Rajendran

Patent number: 7986739Abstract: A method and system for detecting the presence of narrowband transmitters utilizing frequencies also utilized by wider band communication systems. In some embodiments an ultrawideband transceiver detects signals at specific frequencies within a spectrum of frequencies, and analyzes the signals to determine if the signals indicate transmissions by a narrowband transmitter in a narrowband communication system. In further embodiments transmission circuitry reduces signal components at frequencies occupied by the narrowband transmitters.Type: GrantFiled: February 25, 2008Date of Patent: July 26, 2011Assignee: Realtek Semiconductor Corp.Inventors: Turgut Aytur, Stephan ten Brink, Ravishankar H.

Patent number: 7937514Abstract: Universal Serial Bus (USB) is a Master/Salve or Host/Device system in which there is only one host and one or more devices connected by cables to the host. To connect a USB device to a different host controller (say another PC), the user unplugs the USB cable and establishes the connection physically by plugging the cable into the new host controller interface. Certified Wireless USB (CWUSB), a logical extension to the USB, preserves the USB connection model, except that the link between the host and the device is now using a wireless technology. A wireless device is usually connected to only one wireless host at a given point of time, even though several wireless hosts may be co-located in the same physical neighborhood. The connection between the wireless host and device is initiated by the device. A device usually selects a wireless host from a stored set of known hosts that have established a trusted relationship with the device.Type: GrantFiled: November 12, 2008Date of Patent: May 3, 2011Assignee: Realtek Semiconductor Corp.Inventors: Turgut Aytur, Frederic Battaglia, Saurabh Garg, Batuhan Okur, Ping-Wen Ong, Venkatesh Rajendran

Patent number: 7865642Abstract: Certified Wireless USB 1.0 defines two different types of association: cable association and numeric association. In order to implementation these two association methods, the CWUSB device needs to have either upstream USB connector (for cable association) or display capability (for numeric association). These extra requirements make the CWUSB device bulkier (one more USB connector) and/or more expensive (extra display components). For cheap and simple CWUSB devices, we need a simpler association method that is easy and cheap to implement. In a pre-packaged total solution, which includes a host and one or more device(s), we can use pre-association to smooth the user experience. The host and device(s) are pre-associated. When an end user starts to use this solution, they do not need to worry about the association at all.Type: GrantFiled: November 17, 2008Date of Patent: January 4, 2011Assignee: Realtek Semiconductor Corp.Inventors: Turgut Aytur, Fred Battaglia, Saurabh Garg, Batuhan Okur, Ping-Wen Ong, Venkatesh Rajendran, Ran-Hong Yan
