Abstract: An example communication system, including: a plurality of devices that form a mesh-type network, each of the plurality of devices performing communication from a source device to a destination device, directly or by relaying via one or more other devices, and at least one of the plurality of devices including a selecting unit, that selects a communication route from the source device to the destination device according to a first restriction with regard to a relay value indicative of the number of communication routes that each device is able to relay.

Abstract: In an input device, a controller for controlling an input portion and acquiring data is connected to a bus. The bus can be connected with an external expansion device via an expansion connector. The connection of the bus from the expansion connector to the controller is switched on and off by a switcher. Data acquired from a sensor having a function equivalent to that of the external expansion device is transmitted to the controller via the bus by a sensor controller which is connected to each of a side of the controller and a side of the expansion connector of the bus without interposing the switcher. The sensor controller switches the connection of the switcher off when an access to itself is made from the controller.

Abstract: An expanding operating device has a first connector, a second connector and a sensor. The first connector has a first shape physically and electrically connectable with a connector provided with an operating device. Thus, by connecting the first connector to the connector of the operating device, the expanding operating device can be used with the operating device as a single unit, which eventually adds the sensor to the operating device. On the other hand, the second connector has a second shape connectable with a connector with the first shape. This allows a connector conventionally connected to the connector of another operating device to be also connected with the second connector. Accordingly, if the connector of another device is connected to the second connector in a state that the first connector is connected to the connector of the operating device, the another device is eventually connected to the operating device via the expanding operating device.

Abstract: An input device comprises a first storage section for storing game data, a first communication section for communicating with a game apparatus, a first reception control section for receiving game data from the game apparatus, a first write control section for storing the game data received from the first reception control section into the first storage section, and a first transmission control section for transmitting the game data stored in the first storage section to the game apparatus. The game apparatus comprises a second storage section for storing game data, a second communication section for communicating with the input device, a second transmission control section for transmitting the game data stored in the second storage section, a second reception control section for receiving game data from the input device, and a game process control section for executing a predetermined game process using the game data received by the second reception control section.
