Abstract: Provided is a communication apparatus for making connection to a communication network, including: an optical network unit; and an external power supply input/output terminal, the communication apparatus being configured such that electrical power is fed to the optical network unit from an external terminal that is connected to the external power supply input/output terminal and functions as an auxiliary power supply.

Abstract: A power transaction control device for virtually performing a power transaction between a plurality of grids includes a data storage unit that stores order information about power trading between the plurality of grids, and a matching unit that establishes the power transaction between a first site of a first grid of the plurality of grids and a second site of a second grid of the plurality of grids when a pair of the first site and the second site each having an identical price for a selling order and a purchase order of power is established, and when existence of a site that interchanges balancing power identical to balancing power interchanged by the first site in the first grid and existence of a site that interchanges balancing power identical to balancing power interchanged by the second site in the second grid are detected in accordance with order information.

Abstract: A control apparatus that controls power consumption in a service providing system configured to provide a service using servers provided, respectively, in a plurality of bases placed in a geographically dispersed manner, the apparatus including: a target power setting unit configured to set target power values of the respective bases based on requests for increases/decreases in power consumption in the bases equipped with the servers; and a load balance setting unit configured to perform load transfer among a plurality of servers based on the target power values.

Abstract: Provided is a communication apparatus for making connection to a communication network, including: an optical network unit; and an external power supply input/output terminal, the communication apparatus being configured such that electrical power is fed to the optical network unit from an external terminal that is connected to the external power supply input/output terminal and functions as an auxiliary power supply.

Abstract: A guidance information processing device includes a first specifying unit that refers to a first storage unit storing position information of individual facilities, and specifies one or more of the facilities present on a route based on a designation of a user, and a second specifying unit that refers to a second storage unit storing, for each facility, information indicating a sensation capable of being experienced regarding the facility, and specifies a candidate for a sensation to be experienced by the user regarding the one or more of the facilities specified by the first specifying unit at a time of performing guidance on the route, thereby contributing to generation of guidance information suitable for the user.

Abstract: A helper selecting device for selecting a helper for a requester who requires help is provided with: a first storage unit for storing helper candidate information received from a helper candidate terminal; a second storage unit for storing support methods; a helper selecting unit which selects a helper for the requester from among helper candidates, on the basis at least of the distance between the requester and the helper candidates, with reference to the first storage unit, and determines a support method for the requester with reference to the second storage unit; and a notifying unit for notifying the support method for the requester to the helper candidate terminal of the helper candidate selected as the helper.

Abstract: A guidance text generation device that generates a guidance text for a user includes a route generation unit that generates a route including nodes from a point of departure to a destination, the nodes being represented by the point of departure, corners or/and ends at which a traveling direction changes and the destination and geographical information including types for classifying things located on a route connecting nodes, the types being classified into at least one of global brands, universal signs/facilities, objects peculiar to Japan, shops/facilities with alphanumeric notation, and shops, facilities and objects that do not fall under any of such categories and a guidance text generation unit that generates a guidance text for the generated route based on the generated route, the geographical information on the generated route, presentation priority of the geographical information associated with the type of the geographical information.
