  • Patent number: 9118731
    Abstract: An Ad Hoc social networking environment enables information and device access management between social networking groups and social networking members with or without access restrictions and anonymity. Contact and access information can be exchanged and updated on the fly without requiring users to notify other contacts or contacting devices and can support underlying contact information changes, enable extemporaneous termination or modification of contact access, enable temporary access, and the like. Ad Hoc social networking can utilize unique identifiers, proxy elements, or the like to support various levels of membership anonymity and Ad Hoc social networking. Proxy elements enable SNET tear down or dissolution by retracting the proxy service from a member. Storing social group contact information in shared databases can enable sharing and updating of contact information without the need to inform affected contacts. Some social networks can include various specialized devices and related services.

  • Patent number: 9118217
    Abstract: A core module for a portable computing device includes a wireless power receiver module, a battery power module, a power supply module, a processing module, and an RF link interface. The wireless power receiver module, when operable, receives a wireless power transmit signal and converts it into a supply voltage. The battery power module, when operable, outputs a battery voltage. The power supply module, when operable, converts the supply voltage or the battery voltage into one or more power supply voltages. The processing module is operable to select one of the battery voltage, the supply voltage, and one of the one or more power supply voltages to produce a selected voltage. The RF link interface outputs the selected voltage on to an RF link of the portable computing device for providing power to one or more multi mode RF units within the portable computing device.

  • Patent number: 9118444
    Abstract: Embodiments include systems and methods for enabling a physical layer (PHY) link signaling channel between a network termination modem and a cable modem in a cable network. The PHY link signaling channel is embedded within the same multi-carrier channel as the data and enables PHY link up between the network termination modem and cable modem without involvement of higher layers (e.g., MAC). The PHY link signaling channel can be implemented in the downstream (from the network termination modem to the cable modem(s)) or in the upstream from a cable modem to the network termination modem. Embodiments are applicable to any known cable network, and particularly to cable networks implementing the DOCSIS and EPoC standards.

  • Publication number: 20150235701
    Abstract: A pre-computation based TCAM configured to reduce the number of match lines being pre-charged during a search operation to save power is disclosed. The pre-computation based TCAM stores additional information in a secondary TCAM that can be used to determine which match lines in a primary TCAM storing data words to be searched need not be pre-charged because they are associated with data words guaranteed to riot match. The additional information stored in secondary TCAM can include a pre-computation word that represents a range inclusive of a lower and upper bound of a number of ones or zeroes possible in a corresponding data word stored in the primary TCAM.

  • Publication number: 20150237350
    Abstract: In a video processing system, a method and system for generating a transform size syntax element for video decoding are provided. For high profile mode video decoding operations, the transform sizes may be selected based on the prediction macroblock type and the contents of the macroblock. A set of rules may be utilized to select from a 4×4 or an 8×8 transform size during the encoding operation. Dynamic selection of transform size may be performed on intra-predicted macroblocks, inter-predicted macroblocks, and/or direct mode inter-predicted macroblocks. The encoding operation may generate a transform size syntax element to indicate the transform size that may be used in reconstructing the encoded macroblock. The transform size syntax element may be transmitted to a decoder as part of the encoded video information bit stream.

  • Publication number: 20150237584
    Abstract: Embodiments of the present invention provide systems and methods for NFC secure application support when an NFC device is executing in a battery-off or battery-low mode. In such a case, the NFC device may have enough power to execute some applications (e.g., read-only applications) but not enough power to execute others (e.g., applications that require data to be written). Embodiments of the present invention enable these lower-power applications to be executed by the NFC device even when a host communications device has no battery power.

  • Publication number: 20150237676
    Abstract: Dual band wireless local area network (WLAN) transceiver. A wireless communication device includes at least two different transceivers (or radios) therein to effectuate communications with other wireless communication devices using at least two respective frequency bands. Each of these two transceivers may have different respective circuitry (e.g., each may have a different respective power amplifier (PA) and/or other circuitry components). Coordination is made regarding when certain components of one transceiver turn on and operate when another transceiver may be transmitting or receiving communications. For example, the turn on of a PA and/or other circuitry components (e.g., such as components using or requiring high current) within one transceiver can be coordinated as to minimize deleterious effects regarding the operation of another transceiver. Moreover, latency existent within each of the respective transceiver chains within the wireless communication device (e.g.

  • Publication number: 20150237608
    Abstract: A wireless mobile communication (WMC) device may discover available networks, and available local and/or remote resources. The WMC device may configure routes utilizing one or more of discovered resources and one or more available networks. The routes may be utilized to performed operations requested via the WMC device. A standardized language and/or protocol may be utilized in discovering and/or communicating with available resources and/or networks. The standardized language and/or protocol may enable commonality among the discovered networks and/or resources, and encryption of data communicated through the established routes. The standardized language and/or protocol may be updated and/or modified to incorporate new resources either by direct interactions between the new resources and the WMC device, or via existing available resources and/or networks. The discovery of resources and/or establishment of routes may be user-triggered, or it may be based on user preference information.

  • Publication number: 20150237354
    Abstract: Methods are disclosed for performing improved deblocking filtering across edges between macroblocks, with particular application to cases where one macroblock is field coded and its neighbors are frame coded. A method for filtering across horizontal edges comprises determining which macroblocks are considered to be vertically adjacent to each other. The method also determines which macroblocks are considered to be sampled at a same time. Finally, filtering is performed between vertically adjacent macroblocks that are considered to be sampled at a same time. Another method for filtering across vertical edges comprises determining which macroblocks are considered to be horizontally adjacent to each other. The method effectively re-arranges a vertical ordering of horizontal lines of at least a subset of the horizontally adjacent macroblocks. Finally, filtering is performed between the horizontally adjacent macroblocks after the re-arranging.
