  • Publication number: 20140286407
    Abstract: A system and method for resilient signal encoding provide for encoding a data signal to reduce bandwidth required to transmit the encoded signal while mitigating the impact of frames lost or corrupted during transmission. A first frame of the data signal is encoded as an independently decodable frame and is assigned as a reference frame. Subsequent frames of the data signal are encoded as different frames relative to the reference frame. The independently decodable frame and the difference frames are transmitted to a receiver. The receiver decodes the frames and sends an acknowledgement for one or more successfully decoded difference frames. When an acknowledgment is received, a corresponding data signal frame is assigned as the reference frame. Subsequent difference frames are encoded relative to the newly assigned reference frame.

  • Publication number: 20140225915
    Abstract: A display system. A display device has viewports emitting expanded views of an image, an image receiving area receives the image, and optical conduits with exit pupil expanders expand the image through the viewports. A separate tracking projector has an image projector that projects an image along an axis, a marker search illuminator that projects light into a space including the axis, and an image capture component that captures target images that including at least three reflective marker images associated with the image receiving area. An image processor determines, based the marker images, a distance and an orientation of the image receiving area. A projection controller adjusts image data based upon the distance and the orientation to cause projected images to arrive squarely at the image receiving area.

  • Publication number: 20140225916
    Abstract: An augmented reality system with encoding light emitting beacons placed in a scene. Beacons placed at desired locations in a scene emit light modulated with multiple access encoding that conveys an identifier for its emitting beacon. The emitted light signals are also blanked for longer than a time between image capturing by an image augmenting device. Beacons viewed in captured images are identified by correlating an absence of a beacon in an image with an absence of a received identifier in received light signals. In a view of the scene presented to a user, augmenting images are obtained based upon the determined beacon identifier and are displayed at locations in the scene based upon the determined location of that beacon. Beacons that emit pulsed light signals encoded with the multiple access coding are also provided.

  • Publication number: 20140018069
    Abstract: A method for facilitating accelerated network selection on a wireless user equipment (UE) device includes storing information regarding power-off time and power-off location as the UE device is about to enter a power-off condition. Upon power-up, the method further includes computing an estimated distance that the UE device has traveled while in the power-off condition using the stored information and a current time, defining a boundary that lies the estimated distance from a location indicated by the power-off location, for a plurality of regions lying within the boundary, logically sequencing acquisition records that are associated with the regions in a system acquisition database structure based on the regions nearness to the boundary, and locating a network via scanning using scanning data obtained from the logically sequenced acquisition records.

  • Publication number: 20140015848
    Abstract: Displaying a map on a wireless communications device includes downloading map data from which the map is to be rendered, rendering portions of the map for which the map data has been fully downloaded, and then graphically overlaying on a portion of the map for which the map data has not yet been fully downloaded a graphical indication, such as hatching, crosshatching or shading, to indicate that further map data is being downloaded. This hatching, crosshatching, shading, or writing informs the user that further map data is being downloaded and that not all of the map features have been rendered yet.

  • Publication number: 20130223553
    Abstract: A method and apparatus are provided for reducing the number of pilot symbols within a MIMO-OFDM communication system, and for improving channel estimation within such a system. For each transmitting antenna in an OFDM transmitter, pilot symbols are encoded so as to be unique to the transmitting antenna. The encoded pilot symbols are then inserted into an OFDM frame to form a diamond lattice, the diamond lattices for the different transmitting antennae using the same frequencies but being offset from each other by a single symbol in the time domain. At the OFDM receiver, a channel response is estimated for a symbol central to each diamond of the diamond lattice using a two-dimensional interpolation. The estimated channel responses are smoothed in the frequency domain. The channel responses of remaining symbols are then estimated by interpolation in the frequency domain.

  • Publication number: 20130225114
    Abstract: A system and method of provisioning services for a mobile communication device are disclosed. A provisioning request including provisioning information and specifying a provisioning operation and a first communication service is prepared on the mobile communication device and sent to a provisioning system. Processing of the provisioning request is dependent upon whether or not a second communication service has been activated for the mobile communication device. If the mobile communication device is outside a coverage area of a wireless communication network when a provisioning request is prepared, the request is stored at the mobile communication device and sent to the provisioning system when the mobile communication device enters the coverage area. The provisioning system preferably manages service provisioning for multiple services, any of which may be hosted by different service providers.

    Abstract: An identity is communicated by a client device to a server without requiring the identity to be disclosed to eavesdroppers and without requiring the use of symmetric or asymmetric cryptography. In one example, the identity is an identity of the client device, where the identity has been assigned to the client device by the server through the provisioning of a unique subset of client-identifying keys. In another example, the identity is an identity of a group shared secret that has been provisioned by the server to the client device.
