A method and an apparatus for automatically connecting a wireless Local Area Network (LAN) between digital devices and executing an application program based on the wireless LAN, and more particularly, an apparatus and a method for generating device information indicating attributes in a digital device and obtaining attributes of a peripheral device by analyzing device information of the peripheral device. The apparatus includes a device information generation part configured to generate device information including information about attributes by analyzing the attributes of the digital device. The apparatus also includes a device recognition part configured, when receiving device information of a peripheral device, to obtain attribute information of a device corresponding to the received device information. The apparatus further includes a controller configured to control to transmit the device information generated by the device information generation part, to the peripheral device.

A location tracking system and method are provided. The location tracking system includes a plurality of tags which receive a read signal and which output tag signals, a reader which transmits the read signal to the tags, receives the tag signals, and identifies tag IDs from the tag signals, and a data processing system which stores location information of the tags and determines the location of the reader by using the tag IDs received from the reader based on the location information.

An optical switching network has: N input couplers each having a cell input port and a recursive input port, N output couplers each having a cell output port and a recursive output port, N/2 switch couplers connected between the input couplers and the output couplers, and a controller having a routing table, for generating control signals for the respective input, output, and switch couplers upon input of cells. The optical switching network has a single-stage optical recursive loop in which an x-numbered recursive output port is connected to a 2x-numbered recursive input port if 0&lE;x<N/2, and the x-numbered recursive output port is connected to a (2x&minus;N&plus;1)-numbered recursive input port if N/2&lE;x<N. The N input couplers receive the cells via the cell input ports upon input of the cells, the N/2 switch couplers recursively switch the cells log,N-times by connecting the recursive output ports to the corresponding recursive input ports during circulations, and the N output couplers output the cells via the cell output ports at the termination of switching.

A credit inquiry service system for inquiring about the credit standing of a check or credit card uses subscriber lines of a public communication network. The system includes credit inquiry terminals connected to the subscriber lines for generating and transmitting an inquiry request message requesting information regarding the credit standing of the check or credit card. The credit inquiry terminals also receive an inquiry result message corresponding to the inquiry request message via the subscriber lines. The system further includes a line multiplex device for one by one serially selecting the subscriber lines connected to the credit inquiry terminals, receiving the inquiry request message from one of the credit inquiry terminals connected to a selected subscriber line, and transmitting the inquiry result message corresponding to the inquiry request message to the corresponding credit inquiry terminal. A multiplexer is connected to a distributor of the public communication network to facilitate access of the subscriber lines, and to connect a selected subscriber line to the line multiplex device. A computer center receives the inquiry request message from the line multiplex device and transmits the inquiry request message to a card company's computer. The computer center then receives the inquiry result message indicating the credit standing of the check or credit card, and transmits the inquiry result message to the line multiplex device. The line multiplex device then transmits the inquiry result message back to the respective credit inquiry terminal via its corresponding subscriber line.
