Biological gas detection apparatus and biological gas detection method

A disclosed molecular communication system includes a molecular transmitter configured to transmit an information molecule in which prescribed information is encoded, a molecular receiver configured to receive the information molecule, and a molecular capsule configured to carry the information molecule from the molecular transmitter to the molecular receiver. Each of the molecular transmitter, the molecular receiver, and the molecular capsule has an artificial cell membrane in which at least one kind of molecular switch is embedded, the molecular switch being responsive to an external input signal so as to control association and separation between the molecular transmitter and the molecular capsule, and association and separation between the molecular capsule and the molecular receiver, upon application of the external input signal.

System and method for molecular communication

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.

A molecular communication system includes a molecular transmitter () configured to transmit an information molecules () onto which prescribed information is encoded; a molecular receiver () configured to receive the information molecule, a molecule propagation channel () extending from the molecular transmitter to the molecular receiver, and a molecular capsule () configured to encapsulate the information molecules to be transmitted from the molecular transmitter to the molecular receiver, wherein the surfaces of the molecular transmitter, the molecular receiver, and the molecular capsule have lipid bilayer membrane structure, and wherein the system further includes encapsulation means for applying a first chemical substance to the molecular transmitter, or to the molecular transmitter and the molecular capsule to encapsulate the information molecules into the molecular capsule, and decapsulation means for applying a second chemical substance to the molecular capsule and the molecular receiver to take the information molecules out of the molecular capsule and take them into the molecular receiver.

Molecular communication system and molecular communication method

A molecule transfer and delivery system includes a loading zone () for loading a targeted cargo molecule () on a carrier molecule () making use of a hybridization nature of nucleotides, and an unloading zone () 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 () with the first length are bound to the carrier molecule, and the second single-stranded nucleotides () with the second length longer than the first length are bound to the targeted cargo molecule. The third single-stranded nucleotides () with the same length as the second single-stranded nucleotides are bound to the unloading zone.

Molecule transfer/delivery system

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.

Mobile communication system, mobile terminal, and mobile communication method

A mobile terminal includes; a first wireless interface configured to perform communication through a public mobile communication network; a second wireless interface configured to perform direct communication with another mobile terminal; an update information transmitter unit configured to transmit update information including identification information and communication state information of the mobile terminal, to a control device in the public mobile communication network through the first wireless interface at a predetermined timing; a route maintaining unit configured to receive a packet transfer route generated by the control device of the public mobile communication network based on the update information through the first wireless interface, and to maintain the packet transfer route; and a packet transmitter unit configured to transmit a packet to another mobile terminal through the second wireless interface based on the packet transfer route.
