Abstract: A base unit suitable to improve easy exchangeability of a function unit in a dual wiring system is provided. The base unit is mounted in a wall surface of a structure, and connected to both of an electric power line and an information line previously installed in the structure. The base unit has a module port, which is detachably connected to a module connector of the function unit to simultaneously establish both of supplying the electric power from the base unit to the function unit, and making a signal transmission between the base unit and the function unit, thereby enabling the function unit to provide at least one of functions for supplying electric power from the electric power line, outputting information from the information line and inputting information into the information line when connected with the base unit.

Abstract: A dual wiring system which has improved easy exchangeability and function expandability of function unit, and is capable of constructing a higher-order system by controlling plural function units in a coordinated fashion. A plurality of base units are mounted in wall surfaces of a building structure, and connected to both of an electric power line and an information line installed in the building structure. A function unit is detachably connected to each of the base units, and provides at least one of functions for supplying electric power from the electric power line, outputting information from the information line, and inputting information into the information line. A control unit is detachably connected to the function unit or the base unit, and controls at least two of the function units connected to the electric power line and the information line through the base unit(s) in a coordinated fashion.

Abstract: A document server system is described that comprises a plurality of electronic documents, plurality of messages relating to the electronic documents and an interface server for providing a client user interface. The client user interface provides a front user interface configured to display an electronic document to collaborators of the document. The front user interface includes a front switching input. Activation of the front switching input causes the client user interface to switch from the front user interface to a back user interface. The client user interface provides the back user interface configured to display one or more of the plurality of messages for each individual user that is related to the document on the front user interface. The back user interface includes a back switching input. Activation of the back switching input causes the client user interface to switch from the back user interface to the front user interface.
