  • Patent number: 9104703
    Abstract: A converged personal area network service system uses information provided by personal network elements (PNEs) to generate an event report file to store along with a data file to commemorate an event. When the data file is created, such as taking a picture, an event recording device sends requests to PNEs, sensors and other devices within the network to provide information corresponding to a timestamp based on the event. The information, if available, is sent to the event recording device, where it is aggregated. The event recording device generates an event report file that includes fields storing the information pertaining to the data file. The event report file is stored along with the data file for retrieval or use at a later time.

  • Patent number: 9098833
    Abstract: This paper proposes a new method and architecture for populating, updating and managing the NAB. It also proposes user's Contact Information Discovery (CID). In context of populating the NAB; since the NAB of each individual subscriber will be stored in the network in future, the paper proposes CI to flow from one NAB to another NAB within the core network, instead of CI flowing from Device to Network. Thus with the user authorization, his CI would shoot from one NAB to another NAB within the core network instead of from LAB to NAB through air interface. It would reduce huge amount of data traffic on the air that otherwise would be generated in updating and populating the NAB by all the NAB users. In context of CID, the paper proposes a query-response mechanism and introduces a NAB Manager. The new architecture will provide several benefits for example it will eliminate the need of “Number Portability,” “United States National Do Not Call Registry” and “411 Directory Assistance.

  • Patent number: 9100874
    Abstract: One or more system and/or method of dynamically setting values of Channel Access Parameters employing a Load Supervision Manager entity, a Quality of Service Parameters Manager entity, and an Access Point. The entities work with the Access Point and continuously monitors network loading conditions and setting Channel Access Parameters values in response to network loading conditions. The Load Supervision Manager is a controlling and/or supervisory entity that sits at a network level receives information from the QoS Parameters Manager which sits at a subnet level, and judges prevailing loading conditions. The prevailing loading conditions include such factors as the number of Mobile Nodes and the applications or ACs they are running on in each subnet. The QoS Parameters Manager assesses the possible near future loading condition in each subnet including monitoring the hand-off Mobile Nodes and issues directives to QoS Parameters Managers.

  • Patent number: 8981924
    Abstract: In some embodiments, a personal possession management system using a short range Internet Protocol (IP) based Personal Area Network (PAN) comprises a master device MD to be worn or held by a user, and an IP based RFID electronic tag ET to be attached to or contained within a personal possession desired to be managed. The electronic tag ET has communicability with the master device. The master device MD is configured to allot an IP address to the electronic tag ET in a registration mode using IEEE 802.11 protocols and sends probes to the electronic tag ET. The electronic tag ET is configured to receive messages from the master device MD and respond accordingly. The master device MD alerts a user when the communicability between the master device MD and the electronic tag Er is disrupted in a monitoring mode.

  • Patent number: 8908540
    Abstract: A single burst method is used to determine the available bandwidth in a network environment. A sending node transmits test packets to a receiving node. The size of the test packets is dynamically determining based on network parameters within the network environment. The sending node then receives test receipt packets that have the same sequence numbers as the corresponding test packets. Packet clusters are formed from the test receipt packets. The available bandwidth is determined based on the packet clusters along with values set by the single burst method or inputted by a user.

  • Patent number: 8868791
    Abstract: This present application relates to, among other things, novel techniques to evaluate and qualify multiple networking options. A device contains multiple network connectivity options, including but not limited to various wireless and wired technologies such as Wi-Fi, 3G, WiMAX, LTE, Ethernet, Bluetooth, UWB, WHDMI, etc. Each connectivity option can be evaluation and pre-qualified prior to the user selecting that mode of communication. This evaluation process takes into account both lower-layer information such as signal strength, bit error rates, SNR, interference, etc. but also network-layer information such as IP connectivity, and end-to-end path performance.

  • Patent number: 8817990
    Abstract: A media-independent handover key management architecture is disclosed that uses Kerberos for secure key distribution among a server, an authenticator, and a mobile node. In the preferred embodiments, signaling for key distribution is based on re-keying and is decoupled from re-authentication that requires EAP (Extensible Authentication Protocol) and AAA (Authentication, Authorization and Accounting) signaling similar to initial network access authentication. In this framework, the mobile node is able to obtain master session keys required for dynamically establishing the security associations with a set of authenticators without communicating with them before handover. By separating re-key operation from re-authentication, the proposed architecture is more optimized for a proactive mode of operation. It can also be optimized for reactive mode of operation by reversing the key distribution roles between the mobile node and the target access node.

  • Patent number: 8716805
    Abstract: A complementary metal oxide semiconductor (CMOS) circuit having integrated functional devices such as nanowires, carbon nanotubes, magnetic memory cells, phase change memory cells, ferroelectric memory cells or the like. The functional devices are integrated with the CMOS circuit. The functional devices are bonded (e.g. by direct bonding, anodic bonding, or diffusion bonding) to a top surface of the CMOS circuit. The functional devices are fabricated and processed on a carrier wafer, and an attachment layer (e.g. SiO2) is deposited over the functional devices. Then, the CMOS circuit and attachment layer are bonded. The carrier wafer is removed (e.g. by etching). The functional devices remain attached to the CMOS circuit via the attachment layer. Apertures are etched through the attachment layer to provide a path for electrical connections between the CMOS circuit and the functional devices.

  • Patent number: 8706035
    Abstract: A system and method for allowing mobile devices to simultaneously access a Subscriber Identity Module (SIM) are disclosed. The SIM contains a wireless transceiver, and the SIM may be located within a mobile phone, or it may be a stand-alone device. The mobile devices use a wireless protocol, such as Bluetooth, to retrieve identification information from the SIM. The devices then use this identification information to connect to a wireless communications network, such as a wireless local area network. Through this network the devices will be able to access the Internet. The SIM will never need to be removed and inserted from one device to another, and multiple devices can use the SIM simultaneously. Thus, the mobile phone will work regardless of whether other devices are also using the SIM.
