Abstract: An apparatus obtains connection status information of each of terminal devices coupled to a first wireless network via an access point, from the access point. The apparatus detects a disconnected device which is a terminal device whose communication with the access point is disconnected, with reference to the connection status information, and notifies, by using a second wireless network, the disconnected device of a reconnection instruction for instructing the disconnected device to reconnect to the first wireless network by accessing the access point.

Abstract: An apparatus obtains, from an access point, connection status information of each of terminal devices that are coupled to a first wireless network via the access point, and detects a first terminal device which is a terminal device whose communication with the access point is disconnected, with reference to the connection status information. The apparatus notifies, via the first wireless network, a second terminal device coupled to the access point, of an instruction for causing the second terminal device to transmit display information displayed on the second terminal device to the first terminal device by using the second wireless network.

Abstract: A connection processing method includes receiving, by a first processor included in a communication device, first information that specifies a user of the communication device, executing an inquiry for a connection to one or more other communication devices, selecting a target communication device that has transmitted a response including information indicating that the target communication device has second information that specifies the user and has been acquired when the target communication device communicated with another communication device, from among the one or more other communication devices, and transmitting the first information to the target communication device, and receiving, by a second processor included in the target communication device, the first information from the communication device, executing connection processing without executing authentication processing of the user with the communication device, when the received first information matches with the second information, and executi

Abstract: A wearable device stores data therein. The wearable device transmits the data to a master device registered as a transmission destination of the data when communication is possible with the master device. Then, the wearable device transmits, to the master device, a request to cancel registration of the master device registered as the transmission destination of the data. Thereafter, having received a permission to cancel the registration from the master device, the wearable device cancels the registration of the master device and waits for registration of a device with which communication is possible.

Abstract: An electronic device includes a storage, a communication device and a controller. The storage stores information identifying the electronic device. The controller, when starting connection of the electronic device with a first other electronic device, sends the information identifying the electronic device to a second other electronic device when the first other electronic device is connected to the second other electronic device, and connects the electronic device to the first other electronic device when a request for connection with the first other electronic device is received, the first other electronic device receiving the information identifying the electronic device from the other second electronic device.

Abstract: A data communication apparatus 1 has a processing section (CPU) 10 that executes at least a part of communication processing of a communication controller 2 and that executes processing other than the communication processing, wherein The data communication apparatus 1 has an interrupt request blocking section 20 that blocks, during execution of a processing relevant to information exchange concerning a communication condition for the communication controller 2 to carry out a communication processing, an interrupt request to the processing section 10 with priority over the processing relevant to information exchange. With this arrangement, even when additional operation is carried out to execute an interrupt processing during execution of a processing concerning a communication condition such as a modulation system of a modem and a communication speed, the processing can be executed securely and a stable connection of a communication line can be maintained.

Abstract: In a notebook type personal computer, the operation mode of this personal computer is switched into a low power consumption mode even while a screen saver function is actuated. A display apparatus used in such a notebook type personal computer is arranged by a display screen for displaying thereon image data sent from a main apparatus; memory means for storing thereinto screen protecting image data; and display control means for displaying the screen protecting image data stored in the memory means on the display screen under such a condition that the main apparatus is not actually operated for a predetermined time period.

Abstract: A communication method for enjoying service from a service providing system that provides predetermined service to a user after user authentication via a communication line and disconnects the communication line when the user authentication is not completed within a predetermined time is provided. The communication method includes the steps of: (a) activating operations of monitoring a communication state of the communication line and re-setting a communication parameter relating to communication when the communication state is degraded; and (b) suspending, during a predetermined time after the communication line is connected, at least one of the operations of monitoring the communication state and re-setting the communication parameter relating to the communication when the communication state is degraded.
