Abstract: Exemplary communication system 1 includes game devices 10, communication terminals 20, and game support server 30. Game devices 10 enable users to perform a multi-play activity. Each of communication terminals 20 runs an application associated with corresponding game device 10. Game support server 30 divides communication terminals 20 into separate communication groups in accordance with a situation of the multi-play activity performed by game devices 10 so that communication terminals 20 belonging to a same communication group can communicate with each other.

Abstract: A thermoelectric conversion device that includes an element body including a plurality of stacked; and a meandering wire inside the element body and that has a stacked structure. The meandering wire includes a thermoelectric material that has an anomalous Nernst effect, and a thermal conductivity of the plurality of stacked substrates is lower than that of the thermoelectric material. A thermoelectric conversion device that includes a winding core; and a winding wire wound around the winding core. The winding wire consists only of a thermoelectric material that has an anomalous Nernst effect. A thermoelectric conversion device that includes a plurality of substrates and meandering wires on main surfaces of the respective substrates. The meandering wires include a thermoelectric material that has an anomalous Nernst effect, and the substrates adjacent to each other are arranged at an angle that is larger than 0 degrees and smaller than 180 degrees.

Abstract: An example of a server receives first event data from an information processing apparatus. The server stores therein event management data including event state information that indicates whether a second event has already occurred or has not yet occurred. When receiving a request from the information processing apparatus, the server transmits at least one piece of second event data to the information processing apparatus. The at least one piece of second event data includes second event data based on event management data in which the event state information indicates that the second event has already occurred and/or second event data to be transmitted when the second event data stored in the first storage area is insufficient. Upon receiving the third event data indicating that the second event has occurred, the server updates the event state information so as to indicate that the second event has already occurred.

Abstract: Communication system 1 includes communication terminal 20A and game support server 30. Communication terminal 20A runs a game support program associated with game device 10A, to send invitation information to invite user B of game device 10B to a room enabling user A of game device 10A to perform a multi-play activity. Game support server 30, on receiving the invitation information sent from communication terminal 20A, or an invitation acceptance notice sent from communication terminal 20B running a game support program associated with game device 10B, which terminal has received the invitation information, enables users A and B to perform a multi-play activity in the room.

Abstract: A non-limiting example game system includes a game apparatus which is stored with various kinds of application programs. When an application program for a specific service such as a television program guide (program guide program) is started, prior to an acquisition of a content (webpage), an authentication of the game apparatus is performed, and a white list which records a domain name accessible by the game apparatus (the program guide program) is acquired from a managing server which is controlled by a provider of the television program guide. In the program guide program, it is determined whether or not a domain name described in URL of the webpage appears in the white list when a request to send the webpage is to be sent. If not appeared in the white list, the program guide program is suspended, and a web browser is activated to send the request to send the webpage.
