Abstract: A module connection system is configured by connecting a plurality of modules by means of connectors. The modules include a base module, a first module and a second module, and the connectors include a first connector and a second connector. The base module transmits power and signals provided from a driving source, the first module is electrically/mechanically connected to the base module by means of the first connector, and the second module is electrically/mechanically connected to the first module by means of the second connector. The first connector includes a larger number of connection terminals in comparison to the second connector in order to transmit power and signals from the base module to the second module and simultaneously supply power and signals required for the first module.

Abstract: An information classification method includes many steps. In one step a search destination for information stored in an information source is selected, and a classification field with respect to the information is set. In another step the search destination information is searched and judged whether there is a classification field in the information. Another step automatically classifies the searched information based on the classification field. Another step stores the classified information into the database of the user. The present invention thereby automatically classifies the information stored in an information source, stores the classified information into the database of a user and effectively searches and analyzes information using a database system which stores the classified information and displays and outputs the information in various forms.
