  • Publication number: 20080077426
    Abstract: The present invention discloses a method for implementing a prepaid common account, where a user initiates an account resource use request to a service control function management module through a service control function module; the service control function management module determines whether to accept the request, and if the request is accepted, then allocates an account resource to the user depending upon an account resource allocation schema, and returns an allocation result to the service control function module; the user uses the account resource dependent upon the account resource allocation result returned from the service control function module. If the request is not accepted, then a resource allocation failure result is returned to the user, and the process completes. With the inventive solution, a common account based upon the VPN service cannot be enabled for the prepaid user.

  • Patent number: 7265262
    Abstract: This disclosure provides a system for creating cloned cells and embryos that are genetically modified. Cells are treated to increase expression of telomerase and potentially extend replicative capacity. One or more genetic modifications is made to inactivate a gene or confer desirable features, growing and selecting the cells as needed. The modified nucleus can then be transferred to a suitable recipient cell, which can then be used to grow an embryo with the conferred attributes. This technology makes it possible to create embryos, animals and embryonic cell lines with multiple genetic modifications, including homozygously inactivated genes and gene substitutions.

  • Publication number: 20070192160
    Abstract: Systems and methods for supply chain management and identification of feasible plans. Identification of feasible plans includes simultaneous breadth and depth satisfaction of demands. Demands are satisfied using multiple sources of supply, consideration of substitute items, generation of supply, and/or reallocation of supply previously pegged for satisfaction of a lower priority demand. Reallocation optionally includes consideration of items and demands associated with multiple level codes.

  • Publication number: 20050129000
    Abstract: A node selecting method is characterized by comprising a first step of reserving a communication band on a route by seeking a communication route from a source node to a destination node through intermediate nodes by use of an ad-hoc on-demand distance vector (AODV) algorithm in a mobile ad-hoc network; a second step of storing information on communication bandwidth of a link route connecting each pair of neighboring intermediate nodes on the communication route in the intermediate nodes; and a third step of collecting information on available communication bandwidth of the communication route and transmitting it to the source node when a route reply is made from the destination node on the communication route toward the source node.

  • Patent number: 6790931
    Abstract: A novel non-aggressive sulfonating process for aromatic polymers is described. The process encompasses: a). dissolving the aromatic polymer in a substantially anhydrous acid selected from the group consisting of concentrated sulfuric acid, chlorosulfonic acid, and oleum, b) adding an organic solvent which is inert under the conditions of the reaction, c) adding a carboxylic anhydride, d) adding a sulfonating agent, and e) carrying out the sulfonation at a temperature below 25° C. and for a time sufficient to achieve the desired degree of sulfonation.

  • Patent number: 6759441
    Abstract: The present invention relates to polymer blends and polymer blend membranes which consist of a polymeric sulfonic acid and of a polymer which contains primary, secondary or tertiary amino groups, which are prepared via mixing of a salt of the polymeric sulfonic acid with the polymer which contains primary, secondary or tertiary amino groups. The invention further relates to the use of polymer blend membranes in membrane fuel cells, polymer electrolyte membrane fuel cells (PEM fuel cells) or direct methanol fuel cells (DMFC), in membrane electrolysis, in aqueous or non-aqueous electrodialysis, in diffusion dialysis, in the perstractive separation of alkenes from alkene/alkane mixtures (here the membranes are in the SO3Ag form, where the Ag+ forms a reversible complex with the alkene (→facilitated transport)), in pervaporative separation of water from water/organics mixtures, or in gas separation.

  • Patent number: 6525280
    Abstract: Within electronic devices in many cases there exists a need for a manual individual actuation of several switching elements for performing an adjustment of different parameters by a single switch, especially for a pleasure appearance of a front panel and for saving place on the panel. It is an object to provide a switch for this purpose ensuring among others low costs, small size, high reliability, convenient actuation and having good properties for being mounted on a printed circuit board. The actuation means for several switching elements includes an actuating plate being pivotably mounted in a housing on two perpendicular axes and a push-button located within a central opening of said plate.

  • Patent number: 6300381
    Abstract: The present invention provides a process for the preparation of ion-exchange membranes for use in electromembrane processes and ion-exchange membranes obtained from the process. The membranes are prepared from a solution, in a dipolar-aprotic solvent, containing (a) a polymeric sulfonic acid or a polymeric sulfonate salt of formula Polymer-SO3X, where X is H or a monovalent cation, and (b) a basic polymer containing primary, secondary or tertiary basic nitrogen. The dissolved polymer blend is spread in a thin layer onto a support, and the solvent is evaporated to form a polymeric film. The films produced by the process are particularly useful as ion-exchange membranes due to improved properties relative to the component polymers with regard to ionic conductivity, swelling permselectivity, and thermal resistance.
