Abstract: This electronic control device comprises a first priority information table which is provided for each of a plurality of area electronic devices and to which priorities of the area electronic devices from which information is to be acquired are set, and a control unit which refers to the first priority information table when the control unit has determined, from an outside situation of a vehicle, that a state of the vehicle is to change, determines the area electronic device the priority of which is to be changed according to the state of the vehicle to change, instructs the determined area electronic device to change the priority, and acquires, from the area electronic device to which the change in priority is instructed, information the priority of which has been changed so as to have a higher priority.

Abstract: A communication system and so forth that can improve the throughput are provided. The communication system includes a server 1A (first server), another server 1B (second server), and a client 2. The server 1B transmits server information (second server information) indicative of an address of the server 1B to the client 2 through a non-IP communication channel. The client 2 includes a service registry 114C (registry) into which the server information transmitted from the server 1B is stored. The client 2 acquires the server information from the service registry 114C and requests the server 1B corresponding to the address indicated by the server information for a service to be provided by the server 1B.

Abstract: The object of the invention is to provide a functional thin tube device in which a pump and a liquid drawing device are constituted to be not separate without a sophisticated channel design and to correspond to various applications. A functional thin tube device includes a hollow tubular body, a plurality of vibrating ring bodies mounted as being kept in contact with the tubular body spaced an interval along an axial direction on an outer circumference of the tubular body, and an energy supply means of energy for vibrating the vibrating ring bodies. The energy supply means is constituted to supply energy such that the displacement caused by vibrations is mutually different among the vibrating ring bodies.
