Abstract: A communication apparatus including a reception unit that receives a measurement value related to an amount of electric power, which is periodically transmitted to a first destination through a first pathway from an electric power meter through a second pathway that is different from the first pathway, and a transfer unit that transfers the received measurement value to a second destination that is different from the first destination, through a third pathway that is different from the second pathway.

Abstract: A multi-dimensional order making and receiving business matching system for matching a want-to-buy business and a want-to-sell business selected among from a number of want-to-sell businesses in the Internet is described. The matching system comprising a multi-dimensional space as defined with a plurality of variables in order to identify the work content of the want-to-sell business to be matched, and a database which is configured to be accessed in correspondence with the respective points of the multi-dimensional space. The work information of a want-to-sell business is registered in the multi-dimensional order making and receiving business matching system by registering the work information in correspondence with one of the respective points of the multi-dimensional space. The work information of the want-to-sell business to be matched is accessed by searching the database with values which are given to the respective variables of the multi-dimensional space.

Abstract: A new and improved stored program controlled electronic exchange system for a common channel signaling system through separate data links has been found. The control facility of said electronic exchange is shared by a common signal controller and a stored program type computer. The controller processes signals in said data links relating mainly to the transmission of signals such as serial-parallel conversion error control etc., while the computer processes signals relating to the copy of the transmitted signals. A common clock generator is provided for all data links for driving a plurality of MODEM's in said common signal controller and sending a signal in each data link in the same phase.Further, a pair of common signal controllers may be provided on a dual mode operation basis to increase the operational reliability.
