  • Publication number: 20130114684
    Abstract: An electronic device configured for selective run-level coding (SRLC) is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a block of transformed and quantized coefficients (TQCs). The electronic device also determines whether to skip run-level coding. The electronic device further level codes any remaining TQCs if it is determined to skip run-level coding. The electronic device additionally run-level codes one or more TQCs if it is determined not to skip run-level coding and level codes any remaining TQCs if it is determined not to skip run-level coding.

  • Publication number: 20130114687
    Abstract: An electronic device configured for fixed intra run-level mode is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a symbol, e.g. a run-lev pair. The electronic device determines whether a fixed intra run-level mode condition is met. If the condition is met, the electronic device uses fixed intra run-level mode to determine a ‘cn’ value for the symbol. If the condition is not met, the electronic device does not use the fixed intra run-level mode to determine the ‘cn’ value for the symbol. The electronic device run-level codes at least a portion of video data based on the determined ‘cn’ value.

  • Patent number: 8437020
    Abstract: A system and method are provided for selectively emulating printer job processes. The method comprises: receiving a print job from a source; determining a match between received print job commands and default print job commands; mapping non-matching received print job commands to default print job commands; and, printing the print job using an modified set of received print job commands. The job may be printed using a combination of mapped default and received print job commands. The match between received print job commands and default print job commands may be determined by identifying a source print driver identity. The source print driver can be identified in response to parsing PJL commands received with the print job. Then, the method selects a table in response to determining the source print driver identity and accesses the selected table for default print job commands that have been cross-referenced to received print job commands.

  • Patent number: 8437705
    Abstract: A User Equipment (UE) configured for allocating resources and encoding for Channel Quality Indicator (CQI) is described. The UE includes a processor and instructions stored in memory. The UE receives Radio Resource Control (RRC) signaling, receives a reference signal and determines a Channel Quality Indicator (CQI) based on the reference signal. The UE also determines a format for CQI transmission. If use of Format 3 is determined the UE determines cells for CQI reporting based on the RRC signaling and determines an encoding. The UE also encodes a feedback message based on the encoding and transmits the feedback message.

  • Publication number: 20130107164
    Abstract: A liquid crystal display includes a backlight that provides light and selectively modifies the transmission of light from the backlight to the front of the display. The backlight includes a plurality of spaced apart light waveguides and a plurality of selection elements associated with the light waveguides that change the characteristics of the material of the light waveguides to selectively direct the transmission of light toward the liquid crystal layer. The combination of the waveguides and the selection elements provide light to the front of the display in a non-uniform temporal manner and a non-uniform spatial manner during a frame.

  • Patent number: 8422380
    Abstract: The invention is directed to a dynamically reconfigurable network comprising a plurality of nodes having respective transmitters and receivers for transmitting and receiving respective signals to and from one another. In one embodiment, the network is adapted to determine whether a first maximum power can be found at which a first node can transmit a first signal that provides a minimum signal-to-noise ratio at a second node without exceeding a maximum signal-to-noise ratio that a third node requires to simultaneously receive a second signal from a fourth node. If the first maximum power cannot be found, the network is further adapted to cause the first, second, third, and fourth nodes to share a single sub-network. Alternatively, if the first maximum power can be found, the network is adapted to cause the first and second nodes to share a single sub-network that the third node is not permitted to share.
