Abstract: In a communication system having a client and a server capable of communicating with each other via a network, the server can transmit a command to the client in response to a command request transmitted from the client to the server. The server may include a replying unit that transmits replaying data in response to the command received from the client in such a manner that (a) if there is a command to be transmitted to the client, replying data including the command is transmitted to the client, and (b) if there is not a command to be transmitted to the client, replying data, which does not include a command is transmitted to the client. Further, the replying unit may transmit the replying data without a command to the client when a no-command status lasts a predetermined standby period after receipt of the command request.

Abstract: A service providing system is provided including a service providing device adapted to provide a service through a network and a device adapted to receive the service from the service providing device. The device includes a service request unit that requests the service providing device for a service, and a service implementation unit that implements a function of the device after receiving the service from the service providing device that is requested. The service providing device includes a service provision executing unit that provides the service to the device when the service providing device receives the request from the service request unit, and a function judging unit that judges whether the device is equipped with a function to receive the service provided by the service provision executing unit based on equipped function information that indicates functions for which the device is equipped.

Abstract: A parameter setting system includes a setting device and setting target devices. The setting device includes a protocol inquiry mechanism that inquires the setting target device about a communication protocol acceptable to the setting target device; and a setting command mechanism that commands the setting target device to set the function parameter necessary to perform a communication function according to a communication protocol notified in response to an inquiry by the protocol inquiry mechanism. The setting target device includes a protocol response mechanism that notifies the protocol inquiry mechanism of information with respect to a protocol acceptable to the setting target device in response to the inquiry received from the protocol inquiry mechanism; and a commanded setting execution mechanism that sets the function parameter commanded to be set by the setting command mechanism.

Abstract: A communication apparatus as one of first communication apparatuses belonging to a first communication network, for communicating with another of the first communication apparatuses via the first communication network, and with one or more second communication apparatuses via a second communication network, the communication apparatus as the one first communication apparatus including a communication portion which communicates with the different first communication apparatus via the first communication network, and with the one or more second communication apparatuses via the second communication network, and a control portion which controls the communication portion to communicate with the different first communication apparatus via the first communication network, in a first control manner, and controls the communication portion to communicate with the one or more second communication apparatuses via the second communication network, in a second control manner different from the first control manner.

Abstract: A wireless LAN system in which data communication between a wireless station whose connection method as a method for wireless connection can be set to one of a plurality of connection methods and a wireless access point whose connection method has been preset to one of the connection methods is made possible by setting the connection method of the wireless station to a method identical with the connection method of the wireless access point.

Abstract: A network device management system includes a computer that is connected to a network and at least one network device that is connected to the network and is capable of communicating with the computer via the network. Each network device includes a network device controller that provides the computer with network device information about settings and conditions of each network device of the at least one network device, via the network. The network device information includes connection type information that indicates whether each network device is a wired connection type or a wireless connection type. The computer includes a computer controller that obtains the network device information from each network device via the network and outputs a part or all of contents of the network device information including at least the connection type information, based on the obtained network device information.

Abstract: A moving picture data compression device 1 is provided with a controller 20 for inputting a realtime/non-realtime switch signal to switchers 30 and 40 when a realtime/non-realtime switch interrupt is received from a personal computer 3 in order to control a compressor 60 to compress either realtime data recorded on a video tape 5 or non-realtime data recorded on a video file 7 according to a user's desire. When compressing non-realtime data, the controller 20 sends a synchronization signal to the compressor 60, after outputting one field worth of video signal to a buffer 50, in order to instruct the compressor 60 to read data. When the controller 20 receives a one-field read end interrupt, indicative of the end of the reading operation, from the compressor 60, the controller 20 outputs the next field data to the buffer 50.

Abstract: An MPF (Multi Function Peripheral) obtains a BD address and a device name from a communication partner search response when it receives the communication partner search response from a cellular phone. When the MFP successfully obtains the BD address and the BD address is stored in a device management database in a RAM of the MFP, the MFP obtains a user name corresponding to the BD address from the device management database. The MFP obtains settings associated with the user name from an environment database in the RAM of the MFP and stores the same in an environment storage area in the RAM. A display process, etc. in the MFP are performed according to the settings stored in the environment storage area.

Abstract: Disclosed herein is a magnetic tape unit having a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is traveled in contact with the magnetic head during a read/write operation of the magnetic head. During a rest period where the read/write operation of the magnetic head is not performed, a reciprocating motion of the magnetic tape by a small distance is performed with a predetermined period. A temperature in the vicinity of the magnetic head is detected by a temperature sensor. The predetermined period is changed according to the temperature detected by the temperature sensor. Accordingly, the adhesion of the magnetic tape to the magnetic head can be well prevented irrespective of the temperature inside the tape unit.

Abstract: A magnetic tape unit with a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is kept in constant contact with the magnetic head, and a reel motor travels the magnetic tape kept in contact with the magnetic head. Adhesion of the magnetic tape to the magnetic head is prevented by slowly driving the reel motor to travel the magnetic tape at a speed lower than a normal traveling speed for a read/write operation of the magnetic head, during a rest period when the read/write operation of the magnetic head is not performed.
