  • Patent number: 8315807
    Abstract: There is provided a molecular communication system capable of transmitting an information molecule in which predetermined information is encoded to a target destination under good controllability. The molecular communication system includes a molecular transmitter for transmitting the information molecule with prescribed information encoded, a molecular receiver for receiving the information molecule, and a molecule transmission channel extending between the molecular transmitter and the molecular receiver. The molecule transmission channel defines a transmission path formed of macromolecular (or polymer) materials, along which carrier molecules are circulating in a prescribed direction. The information molecule output from the molecular transmitter is loaded on the carrier molecule and carried to the molecular receiver.

  • Patent number: 7981638
    Abstract: A molecule transfer and delivery system includes a loading zone (50) for loading a targeted cargo molecule (30) on a carrier molecule (20) making use of a hybridization nature of nucleotides, and an unloading zone (40) for unloading the targeted cargo molecule from the carrier molecule making use of the strand exchange nature of the nucleotides. Towing nucleotide chains including the first single-stranded nucleotides (21) with the first length are bound to the carrier molecule, and the second single-stranded nucleotides (31) with the second length longer than the first length are bound to the targeted cargo molecule. The third single-stranded nucleotides (41) with the same length as the second single-stranded nucleotides are bound to the unloading zone.

  • Patent number: 7400601
    Abstract: It is an object of the present invention to provide a mobile communication system capable of shortening a delay time preceding the reception of a multicast packet at a radio base station which has been reached by a movement of a mobile terminal. The mobile communication system includes a multicast router, a data layer link switch, a radio base station, and a mobile terminal. In cases where the mobile terminal detects switching of the radio base station but does not detect switching of the multicast router, a path establishing request, a withdrawal request, and another path establishing request are sequentially output. When the switching of the radio base station and the switching of the multicast router is detected, a path establishing request is transmitted to the new multicast router, and a withdrawal request is transmitted to the previous multicast router thereafter.
