Abstract: Systems and methods for displaying a teleconference session are described. Teleconference data including display streams is transmitted to a number of client computers. Each of the streams may include at least a video and an audio component. A user interface includes a first display area rendering a first stream and a second display area rendering a second stream. An event may occur that removes a video component from the first stream. In response to the event, the rendering of the first stream may be removed from the first display area, and one or more streams of the plurality of streams may be displayed in at least a portion of the first display area. Such techniques for modifying user interface displays based on the actions of select users that have transitioned to an audio-only mode can optimize the use of a display area.

Abstract: In an optical display system that includes a waveguide with multiple diffractive optical elements (DOEs), an in-coupling DOE couples light into the waveguide, an intermediate DOE provides exit pupil expansion in a first direction, and an out-coupling DOE provides pupil expansion in a second direction and couples light out of the waveguide. The intermediate DOE is configured with a crossed grating which is a three-dimensional microstructure that is periodic in two directions. The crossed grating provides multiple optical paths to a given point in the DOE in which differences in optical path lengths are larger than the coherence length. The crossed grating in the intermediate DOE may provide increased display uniformity in the optical display system by reducing the “banding” resulting from optical interference that is manifested as dark stripes in the display. The crossed grating can further enable the optical display system to be more tolerant to manufacturing variations.

Abstract: Methods and systems are provided for generating personalized greetings for presentation by a personal digital assistant on a client device. An indication is received from the client device associated with the user that the personal digital assistant has been launched on the client device. User-specific information and contextual information is retrieved by querying a user profile database and one or more services. A personalized greeting engine utilizes the user-specific information, such as user inferences and interests, and the contextual information to generate the personalized greetings for presentation by the digital assistant on the client device.

Abstract: Techniques are described for providing and accessing network services via a peer-to-peer wireless network connection which is established between a first computing device and a second computing device. The first computing device has an additional network connection that allows it to access network services via external networks (e.g., the internet). The second computing device is only connected to the peer-to-peer wireless network connection and has no Internet access. A primary data channel is established between the first and second computing devices over the peer-to-peer wireless network connection (e.g., for streaming audio and/or video content). A secondary data channel is negotiated between the first computing device and the second computing device. The secondary data channel is used by the second computing device to access the network services via the first computing device which performs relay and/or proxy operations for the second computing device.

Abstract: Embodiments are disclosed that relate to touch input detection in a touch sensor. One example provides a method comprising establishing a first reference sequence, starting with a first set of candidate reference sequences each differing from the first reference sequence, reducing the first set of candidate reference sequences by applying a rule set to the first set to derive a relatively smaller second set of candidate reference sequences, for each candidate reference sequence in the second set of candidate reference sequences, calculating a touch detection performance score of a combined reference sequence, and configuring at least a portion of a receive circuit to correlate signals to at least one of the touch detection conditions by using the first reference sequence in a combined correlation operation with at least a selected candidate reference sequence from the second set of candidate reference sequences.

Abstract: Polynucleotide sequencing generates multiple reads of a polynucleotide molecule. Many or all of the reads may contain errors. Trace reconstruction takes multiple reads generated by a polynucleotide sequencer and uses those multiple reads to reconstruct accurately the nucleotide sequence. The types of errors are substitutions, deletions, and insertions. The location of an error in a read is identified by comparing the sequence of the read to the other reads. The type of error is determined by comparing both the base call of the read at the error location and base calls of the read and other reads in a look-ahead window that includes base calls adjacent to the error location. A consensus output sequence is developed from the sequences of the multiple reads and identification of the error types for errors in the reads.

Abstract: Methods for predicting future spectrum utilization are disclosed. Monitoring of spectrum signatures in a first system during a first time period may indicate that a particular frequency spectrum is being used by at least one device or second system for at least one type of application based on monitored spectrum usage. Knowledge of the monitored spectrum usage may be used to determine a prediction of how the frequency spectrum will be used in a second time period by the at least one device or second system, and the prediction may be utilized for selecting portions of the frequency spectrum for use in the first system during the second time period. The knowledge of the monitored spectrum usage may be combined with information in a database when determining the prediction of use.

Abstract: A computing device initiates a linked capture session to enable automatic image sharing by multiple users and devices. The linked capture session is a group of devices that automatically share captured images during the linked capture session. The linked capture session may be initiated based on a location, a group of people, and/or a time duration. The images captured by devices that are connected in the linked capture session are automatically communicated to a remote storage system that allows all users to access the images through devices connected to the linked capture session.

Abstract: The disclosure generally relates to identifying a Bluetooth Low Energy (BTLE) enabled Wi-Fi network receiver and automatically connecting to the BTLE-enabled network receiver via a Wi-Fi signal without using a Wi-Fi scanning operation. In some aspects, an initial connection may be established between the network receiver and a BTLE-enabled device during which the Wi-Fi scanning operation of the device is disabled. Thereafter, the device may automatically detect the BTLE-enabled network receiver via BTLE signal and automatically connect to the network receiving using a Wi-Fi signal without using the Wi-Fi scanning operation. In this way, the battery life of the device may be conserved by disabling the Wi-Fi scanning operation. Although the electronic device may be within the Wi-Fi range of the network receiver, the device may not search for or connect to the network receiver if it is outside of the BTLE range of the network receiver.

Abstract: A system comprises an aerial imaging platform configured to rise to a height above ground. An apparatus allows an entity to move the aerial platform in a desired direction. The aerial platform includes a camera positioned to capture images of the ground. The camera includes a position sensor. A user/entity may move the aerial platform over a region to be imaged. The system includes a device that may be carried by the user/entity. The device receives information about a region to be imaged and a field of vision of the camera, determines a first path, and provides information on the first path to the user/entity. As the user/entity moves the aerial platform along the first path, the device receives data from the camera position sensor and determines a second path. The user/entity may then move the aerial platform along the second path to capture unimaged areas of the region.
