  • Patent number: 8102929
    Abstract: Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.

    Abstract: The described apparatus and methods include a wireless local area network (WLAN) access point having a wireless wide area network (WWAN) backhaul connection to provide a gateway between a LAN and a WAN. In one example, the access point may be a cellular telephone. Here, a processor in the access point is configured to generate a plurality of master keys, such that a plurality of access terminals may each utilize a respective one of the master keys to access the LAN. Further, the processor is configured to enable control of an allocation of resources to at least one of the access terminals.

  • Publication number: 20110145879
    Abstract: This disclosure describes techniques that can improve the generation of a decomposed multi-stream (DMS) by a host device of a video display system and the display of a DMS by a client device of the video display system. The techniques may apply different frame rates to different streams within a DMS, and the frame rates may depend on the content. For example, one stream within a DMS may comprise a sequence of full-motion video information, which may be rendered at a relatively high frame rate. However, another stream within the DMS may be associated with a background of the display, various graphic user interface control windows or elements, or a display window that includes non-video content (such as e-mail or a document). The second stream in the DMS may be rendered at a much slower frame rate than that used for the sequence of full-motion video information.

  • Publication number: 20110090144
    Abstract: A method sends a signal to render visual information on a display, and receives a user response to the rendered visual information. The user response includes a first delay. The method also queries an electronic system for data indicating a second delay. The second delay is a portion of the first delay and attributable to the electronic system. The method further using the data indicating the second delay to compensate for electronic system delay during interactions with a user.

  • Publication number: 20110026591
    Abstract: A method of compressing video content is disclosed and may include receiving an image frame of a video signal having multiple components, generating an edge-map for the image frame, generating a bitstream base layer for each component of the video signal, generating a first bitstream enhancement layer for each component of the video signal, and generating successive bitstream enhancement layers for each component of the video signal. As the successive bitstream enhancement layers are generated, the method of compressing video content goes from lossy to lossless.

  • Publication number: 20110013644
    Abstract: Systems and methods identify a multi-hop network data path with sufficient available resources at each node along the data path to facilitate desired end-to-end data flow. Embodiments operate to identify resource constraints for meeting QoS or other communication requirements at each node of a multi-hop data path and propagate the resource constraint information within the network for use in identifying data paths suitable for supporting a desired end-to-end data flow. A resource allocation algorithm operable to allocate resources to achieve an end-to-end data flow meeting the communication requirements is implemented according to embodiments. A resource allocation algorithm of embodiments operates to ensure efficient use of the available resources so that desired conditions are satisfied when the resource requirements are met at each intermediate node for the upstream and downstream links and also both links simultaneously.
