Abstract: A first server in a system includes confirmation requesting unit 110 that receives an authentication request from a predetermined apparatus 400 coupled through a public line and that sends a user confirmation request to a second server in the case where user authentication is successful. A second server includes a user facility identifying unit 210 that receives the user confirmation request from the first server and identifies location information of the user facility of the user and a confirmation result notifying unit 211 that receives a utilization request from a measuring apparatus linked through a dedicated line and identifies disposition location information of the measuring apparatus and that sends a notification of success of user confirmation including the identification information of the user to the first server 100 if the disposition location information of the measuring apparatus is identical to the user facility location information.

Abstract: A wireless device according to the present invention minimizes the need for changing a communication route in an ad hoc network including wireless devices used for base stations, fixed stations, and mobile stations that are turned on/off or moved, wherein, when wireless devices cannot directly send or receive radio waves, data can be transmitted between them by relaying data via other wireless devices that can directly send or receive radio waves (multi-hopping). In selecting a communication route, a communication route that includes wireless devices that are turned off or moved least frequently is selected.

Abstract: An appliance located states accumulating method includes the steps of, receiving state information indicating operating state changes of the appliances constituted of a distributed computer through a network, calculating an occurrence time difference from the state changes occurred in the appliances in accordance with occurrence time information indicative of occurrence times of the state changes included in the state information, and calculating the positional relation of the positions, where the appliances occur the state changes, from the calculated occurrence time difference, thereby accumulating the positional relation of the installed appliances.

Abstract: A command processing device includes: a command reception section for receiving command data formed by a plurality of element data by successively receiving the element data; a state transition pattern storage section for storing a processing state transition pattern in the interpretation process of the command data; a state transition section for processing the element data one by one in the interpretation process of the command data and changing the processing state in the interpretation process according to the state transition pattern each time one element data is processed; and a control section for executing control according to the state finally decided by the state transition section.

Abstract: In a distributed processing system including a plurality of intelligent devices such as an optical sensor and a processing machine connected via a network to each other, when a first optical sensor is moved from a first section to a second section, if an identifier indicative of the second section is set, then the first optical sensor transmits a retrieve message containing this identifier via the network so as to seek a second optical sensor which is set to the same second section. Then, the first optical sensor acquires a setting parameter from the second optical sensor, and executes an operation in cooperation with the second optical sensor set in the same second section. As a result, in such a distributed processing system including a plurality of computers (intelligent devices) whose processing contents are different from each other, depending upon setting places thereof, workloads for changing the setting values of these computers can be reduced.

Abstract: In servers that distribute mobile agents, controlling the traveling time of distributed agents is difficult. Also, maintenance management is difficult when there are large numbers of frequently updated mobile agent traveling destinations.

Abstract: A gas/vapor electromagnetic induction machine comprises an annular coil container including two coaxial electrically insulating cylinders connected at lower ends to an annular bottom plate and coaxially disposed around an iron core within an enclosed tank charged with a non-condensable electrically insulating gas and a condensable cooling gas. A dripping pan receives a condensate of the cooling gas located on the lower portion of the tank through the operation of a pump and drops the condensate into the annular coil container and onto the iron core assembly located within the annular coil container. Thus a coil is always partially or entirely immersed in the condensate collected in the annular coil container.
