Abstract: An information processing system includes a host module and a plurality of function modules. The host module includes an interface selector, an interface information notification module, an interface information confirmer and a communication control information storage. The interface selector is configured to select one of the plurality of function modules. The interface information notification module is configured to notify interface information of the selected one function module to at least the one function module which the interface selector has selected. The interface information confirmer is configured to receive a first identifier of the selected one function module from the one function module which the interface selector has selected. The communication control information storage is configured to store the first identifier associated with the interface information. Each of the plurality of function modules includes an interface information obtainer and an interface information response module.

Abstract: According to one embodiment, a communication device includes a single communication module and a controller. The single communication module operates in a first mode or a second mode. The first mode corresponds to near-field wireless communication. The second mode corresponds to wireless communication performed in a longer communication distance than a communication distance at which the near-field wireless communication is performed.

Abstract: According to one embodiment, an electronic device transmits a probe request frame to a wireless LAN access point through a first channel in a first frequency band, extracts additional information about a second frequency band higher than the first frequency band from a probe response frame received from the wireless LAN access point, changes a channel to be used by a wireless LAN device to a second channel in the second frequency band indicated by the additional information, and executes a sequence for connecting the electronic device to the wireless LAN access point by using a first service set ID indicated by the additional information and corresponding to the second channel.

Abstract: According to one embodiment, an electronic apparatus includes a display process unit and a data transmission process unit. The display process unit is configured to display connection confirmation information, which is known to a user and is transmitted from a device via a network during a connection establishing process for establishing connection between the device and an electronic apparatus, on a display screen of the electronic apparatus. The data transmission process unit is configured to start a process of transmitting the data that is to be kept secret to the device via the network in response to a predetermined user operation which indicates that the user has confirmed that the connection confirmation information displayed on the display screen is correct.

Abstract: The present invention comprises a communicating means to communicate with external device providing content, a storage medium retaining the content capable of recording and reading the content, recording and reproducing means which record the content obtained by means of the communicating means in the storage medium and which read and reproduce the content recorded in the storage medium, a recording operation means to execute a recording operation, control means which judge the recording and reproducing process conditions when the recording operation means is operated, and if the content is reproduced, after stopping the reproduction, while if the content is not reproduced, immediately, control the content received by means of the communicating means so as to be recorded in the storage medium.

Abstract: A wireless communication device for wirelessly transmitting data from a plurality of data sources to a different device. The wireless communication device includes: an authentication unit that authenticates the different device; an encryption unit that encrypts the data from the data source using a cipher key; a communication unit that transmits the data encrypted by the encryption unit to the different device authenticated by the authentication unit; a switch unit that switches the data source for supplying the data transmitted to the different device; and a cipher key update unit that updates the cipher key used by the encryption unit when the switch unit switches the data source.

Abstract: After an encryption key creating unit creates/updates an encryption key, an encryption key update timing control unit monitors whether or not the elapsed time since this time has reached the shortest holding time or longest holding time. If the shortest holding time has elapsed, the encryption key update timing control unit monitors whether or not wireless communication is being executed by a wireless unit. If a state wherein no wireless communication is being executed is detected, the encryption key creating unit is caused to create/update an encryption key at this timing. When the longest holding time has elapsed while this state is not detected, the encryption key update timing control unit gives a wireless unit an instruction to temporarily interrupt the wireless communication, and causes the encryption key creating unit to create/update an encryption key during interruption of wireless communication.

Abstract: An electronic apparatus includes a main body and a communication device which is removably attached to the main body. The communication device includes an antenna, a communication unit which executes communication with another electronic apparatus via the antenna, a memory which stores an authentication code, and an authenticating unit which reads the authentication code stored in the memory and executes an authentication process using the authentication code when the communication with the another electronic apparatus is executed by the communication unit.

Abstract: A card includes a memory configured to rewritably store data, a communication unit configured to transmit/receive data via a wireless communication, an interface connectable to an external device, and a controller configured to execute direct access control to the memory via the communication unit. The controller is set in a direct access mode by a command supplied via the interface (or by an operation of a switch).

Abstract: A method for manufacturing a vacuum interrupter including, a vacuum enclosure composed of an insulating tube sealed by metal flanges, a pair of electrodes in the vacuum enclosure which are able to make and break contact, and a pair of conducting shafts.
