Mobile node, access gateway, location management device, and mobile packet communication system
When a mobile station 1 transmits a packet to a mobile station 2, the mobile station 1 selects an MAG 1 based on a primer flag of the MAG in a default router list, and transmits the packet to the MAG 1 as a default router. The MAG 1 receives the packet and resolves an LMA by finding that a destination of the packet is not a mobile station associated with the MAG 1 from a location information management table. Then the MAG 1 transfers the packet to the LMA. A transfer unit sets a transfer source as the MAG1 and a transfer destination as the LMA, and transfers the packet by a transfer technique using encapsulation, a transfer technique such as GRE tunneling, or MPLS. The LMA searches the location information management table based on the mobile station 2 as the destination of the packet, acquires an MAG 3 whose primer flag is ON, and then transfers the packet to the MAG 3. This allows each of the mobile stations to establish multiple communication paths via multiple communication networks, and to select an optimal path to deliver a packet in a mobile communication system complying with the Edge Mobility and provided with mobile stations, access gateways, and a location management device. |

Pole shifting generator
An apparatus and method generate electric current within a specified frequency range from a rotor operating within a broad range of rotational speeds by reducing the number of poles of the generator at higher rotational speeds. At higher rotational speeds, the generator circuit is altered so that a flow of current through half of a plurality of windings is reversed and the polarity in the said half of the windings is reversed. Two adjacent windings with the same polarity create a single pseudo pole, which effectively reduces the number of poles in the generator by half, and reduces the frequency of the electric current produced by the generator. Thus, the generator is operable to produce current within a specified frequency range from a rotor operating within a broad range of rotational speeds. |

Oil-dispersible composite of metallic nanoparticle and method for synthesizing same
The present invention provides an oil-dispersible composite of metallic nanoparticles and a method for synthesizing the same. The composite primarily includes metallic nanoparticles and an oily polymeric polymer such as polyurethane (PU). The oily polymeric polymer serves as a carrier of the metallic nanoparticles by chelating therewith so that the metallic nanoparticles are dispersed uniformly. In the method of the present invention, the metallic ions are first chelated by the oily polymeric polymer and then reduced into nanoparticles. The composite of the present invention is about 5 to 100 nm in particle size. |
