  • Patent number: 7272397
    Abstract: Some embodiments provide a system for authorization and authentication of an unlicensed mobile access (UMA) subscriber. The system includes an UMA network controller (UNC) which is communicatively coupled to a licensed wireless communication system. The system also includes an access point (AP) that serves a wireless local area network (WLAN). The system further includes a mobile station (MS) that is communicatively coupled to the AP and the licensed wireless communication system. The system also includes an authentication server that is communicatively coupled to the UNC. The authentication server authenticates a UMA subscriber for accessing an unlicensed mobile access network (UMAN) that includes the UNC and the AP. [Some embodiments define an interface between the UNC and the authentication server uses Remote Access Dial-In User Service (RADIUS) protocol. In some embodiments, the authentication server is an Authorization, Authentication, and Accounting (AAA) server.

  • Publication number: 20070157342
    Abstract: The present invention provides methods and compositions for making and using transgenic plants that exhibit increased nitrogen storage capacity compared to wild-type plants. Methods of the invention comprise inducing overexpression of monocot-derived vegetative storage proteins (VSPs) in plants, particularly in monocots. In some embodiments, at least one nucleotide construct comprising a nucleotide sequence encoding the ZmLox6 protein or a biologically active fragment or variant thereof is introduced into a plant. Depending upon the objective, the nucleotide construct may optionally comprise an operably linked coding sequence for a vacuolar sorting signal or plastid transit peptide in order to direct storage of the ZmLox6 protein or biologically active fragment or variant thereof into the vacuolar compartment or plastid compartment, respectively, of the cells in which the VSP is expressed.

  • Publication number: 20060277594
    Abstract: The present invention allows a user (e.g., a policy implementer) to be identified and delegated responsibility for implementing a policy. This can occur, implicitly, semi-implicitly or explicitly. In a typical embodiment, a policy provided (e.g., by a policy owner) is automatically parsed to determine a minimum set of access rights needed to implement the policy. For example, the policy might indicate that an implementing user only needs simple read privileges. Alternatively, the policy might require read/write privileges. In any event, a list (e.g., an access control list) will be analyzed to identify a set (e.g., one or more) of users of a computerized resource subject to the policy that meets the minimum set of access rights. Once this set of users has been identified, a hierarchy can be optionally analyzed to determine who among the set of users is permitted to implement the policy.

  • Publication number: 20060209799
    Abstract: Some embodiments provide a system for handling communications between an unlicensed mobile access (UMA) network controller (UNC) and a licensed wireless communication system. The systems of these embodiments include a serving general packet radio service support node (SGSN) or a mobile switching center (MSC) that is communicatively coupled to the UNC. In such systems the UNC and the SGSN communicate utilizing a subset of a protocol standard message set. The protocol standard message set includes messages for handing discovery and registration, circuit switching domain and packet switching domain signaling, and circuit switching based data and packet switching based data. The subset for the SGSN is for handling packet switched domain signals and packet switching based data. The subset for the MSC is for handling circuit switched domain signals and circuit switching based data.

  • Publication number: 20060107585
    Abstract: The process generates energy from organic material utilizing microwaves. The waste from food item is dried and further heated under temperature control to convert it into a renewable source of energy. Enclosed in a glass chamber (2) it is then exposed to microwave energy. Apparatus comprises a microwave oven (1), a heat exchanger (3) and energy extraction systems (5) and (6). The microwave absorption creates an ionized hot air atmosphere of high-energy Plasma. This new process for hot plasma generates heat, pressure and electromotive energy, which can be converted by a heat exchanger; a microwave ignited internal-combustion engine or a Magneto-Hydrodynamic (MHD) system, to the useful form of mechanical or electrical energy. The process incorporates a method for plasma confinement to harness its energy. Suitable feedback-control (7) makes the process self-sustaining with net gain in the output energy. Energy efficiency of the process measures the nutritional value of food item used.

  • Patent number: 7035846
    Abstract: A framework for answering Lightweight Directory Access Protocol (LDAP) queries from previously cached queries includes a proxy server configured to receive client directory queries. The proxy server maintains a cache of data (entries) and semantic information associated with a query. In response to a query received from client, the proxy invokes a query containment procedure which uses the semantics of the incoming and stored queries to determine whether the query can be answered from cached queries. The proxy answers queries from the local cache when possible, and for other queries it sends the request to a directory server. The semantics of the new query and the resulting data (entries) are added to the cache. The method and apparatus can be used for positive conjunctive queries for answering equality, range and substring queries.

  • Publication number: 20050272449
    Abstract: Techniques for performing messaging between mobile stations (MSs) and UMA network controllers (UNCs) in an unlicensed mobile access network (UMAN). URR (UMA radio resource) messages are exchanged between an MS and one or more UNCs to perform various operations associated with UMAN. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.
