Abstract: Methods and systems for reducing communication during video processing utilizing merge buffering are disclosed and may include storing data in a merge buffer in the virtual machine layer in a wireless communication device comprising a virtual machine user layer, a native user layer, a kernel, and a video processor. The data may then be communicated to the kernel via the native user layer. The data may include function calls, and/or kernel remote procedure calls. The data may be communicated via an application programming interface. Video data may be processed in the video processor based on the communicated data. The virtual machine user layer may include a Java environment. The data may be communicated to the kernel via the native user layer when the merge buffer is full or filled to a predetermined level.

Abstract: A wireless communication system includes an access point and first and second stations. The first station transmits a first message that includes an address of a second station as a destination address and an address of the first station as a source address. The access point forwards the message including the address of the second station address as the destination address and the address of the first station as the source address. The second station receives the message from the first station during a first time interval and receives the first message from the access point during a second time interval. The second station processes the duplicate received message to produce inbound data.

Abstract: A GNSS enabled handset receives signals from different resources comprising GNSS satellites and/or from a wireless network. The GNSS enabled handset acquires location information comprising various positioning resource data comprising GPS data and/or WiFi data from the received signals. The GNSS enabled handset calculates a plurality of possible position fixes based on the acquired location information using various positioning approaches. A current position fix associated with the GNSS enabled handset is determined based on the plurality of calculated possible position fixes via running a location-based service (LBS) client on the GNSS enabled handset. The LBS client determines the plurality of possible position fixes using various positioning approaches in a particular or determined order. Confidence levels for each of the calculated plurality of possible positions are determined and used to refine the current position fix.

Abstract: A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. An operator may touch, or be sufficiently proximate to, an antenna module of the NFC device to operate and/or control the NFC device. The antenna module includes antenna components that are characterized by a corresponding characteristic impedance. The touch, or sufficient proximity, of the operator changes the corresponding characteristic impedance of antenna components. The NFC device may determine a location of the touch, or proximity, of the operator based upon this change. The NFC device may interpret the location of the touch, or proximity, of the operator as information from the operator to operate and/or control the NFC device.
Abstract: A wireless device (11) checks channel quality on a second data link between itself and a network access point (20). If the device (11) receives a message from a first node (10) to the network access point (20) indicating that the first node (10) is terminating (202) a first data link with the network access point (20), the device (11) conditions its own termination of the second data link on a re-assessment (208) of the channel quality (e.g. delay and throughput) after the first data link is terminated.
Abstract: Gateway based and centric network management and coordination. Coordination and management of delivery of a source sequence, that has possibly undergone adaptive bit rate (ABR) encoding upstream to generate a number of respective fragments that may have different respective bit rates associated therewith, to one or more downstream, user, or client devices is achieved via appropriate communication network management and coordination performed by one or more communication devices within the system. In one instance, a home gateway communication device operates to perform such coordination management of a convergent network or convergent digital home network (CDHN). Consideration of any one or more local and/or remote conditions, parameters, etc. may be employed by such an application to ensure effective delivery of a source sequence to one or more client devices.

A method of secure key handling and cryptographic processing of data, comprising receiving a request from an entity to cryptographically process a block of data, the request including a key handle, wherein the key handle includes an authentication tag and an index; authenticating the requesting entity using the authentication tag; and referencing a plaintext key from a plurality of plaintext keys using the index if the requesting entity is authenticated successfully.
Abstract: A communication device includes a communication interface and a processor configured to generate, transmit, receive, and process signals. The communication device generates orthogonal frequency division multiplexing (OFDM) frame(s) that include a two-dimensional (2D) start burst marker (BM), a data payload, and a 2D stop BM, and transmits the OFDM frame(s) to another communication device. Alternatively, the communication device receives OFDM frame(s) that include a 2D start BM and a 2D stop BM, and then identifies a data payload within those OFDM frame(s) based on the 2D start burst marker and a 2D stop BM. The 2D start and stop BMs are based on predetermined sequences having particular formats based on corresponding 2D sub-carrier and OFDM/A frame based structure. A receiver communication device then detects the 2D start BM and 2D stop BM within the received OFDM frame(s) based on knowledge of these predetermined sequences and particular formats.

Abstract: Aspects of a method and system for customized full ephemeris compatible with standard AGPS network devices allows a GPS enabled handset to receive real-time full ephemeris from an AGPS server for calculating a position fix. The real-time full ephemeris may be generated at the AGPS server in response to one or more request for real-time full ephemeris from the GPS enabled handset. The AGPS server may be configured to provide fresh full ephemeris generated at smaller intervals such as every 10-15 minutes as approximated real-time full ephemeris. The generated real-time full ephemeris or fresh full ephemeris may be communicated to the GPS enabled handset periodically or aperiodically. Various predicted real-time full ephemeris or predicted fresh full ephemeris compatible with various standards may be generated via Short Term Orbits (STO) technology.

Abstract: Downclocking and/or adaptive sub-carriers for single user, multiple user, multiple access, and/or MIMO wireless communications. Communication device operation within a wireless local area network (WLAN/WiFi) is effectuated in the frequency spectra typically associated with television broadcast channels. Operation is made on a secondary non-interfering basis to such television broadcast channels. Any desired channel bandwidth (e.g., 6 MHz, 7 MHz, 8 MHz, etc.) may be employed. Adaptation with respect to the number of data sub-carriers within different respective packets may be made in accordance with two or more respective operational modes. For example, modification of the number of data sub-carriers in different respective packets may be made to increase the signal bandwidth from a first band was to a second bandwidth.
