  • Publication number: 20230276303
    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.

  • Patent number: 11081053
    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.

  • Publication number: 20200351781
    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.

  • Publication number: 20180075511
    Abstract: A system for extracting attributes can analyze text from data sources, extract n-grams from the text as candidate attribute and service/product pairs, prompt a human operator to rate the suitability of the candidate attribute and service/product pairs, and, based on the ratings, add the candidate attribute and service/product pairs to an attribute dictionary. In embodiments, an attribute extraction system includes an n-gram extractor, an attribute selector interface, and a dictionary builder. Data sources may include product titles, category descriptions, product descriptions, and like data from one or more product databases. In embodiments, the attribute dictionary is analyzed to determine canonical names for products or services and name variants for the products or services.

  • Patent number: 7987304
    Abstract: 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.

  • Patent number: 7986739
    Abstract: 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.

  • Patent number: 7937514
    Abstract: 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.

  • Patent number: 7865642
    Abstract: 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.
