Abstract: A broadcast message may be initiated or received at a peer node. The node obtains an uplink bandwidth available for broadcasting the message over the network and a number of copies that can be broadcast based on the available bandwidth. The node determines a range of key values for finger nodes that should receive copies of the broadcast message from a finger table. The finger table entries include references to finger nodes and key values associated with the finger nodes. The node determines which other nodes should receive copies of the broadcast message from range of key values and the number of copies. The node also determines an End ID for each recipient node. A copy of the broadcast message and corresponding End ID is sent to a finger node if the finger node's key value is within a range of key values specified by the End ID.

Abstract: A community establishing site is connected to an information terminal via a network. When the user enters a search keyword into the information terminal, an entered-information acquiring unit acquires the search keyword through a web server, and registers it together with user information in a user information master. A community establishing unit extracts users who have entered the same search keyword, from the plurality of users registered in the user information master, and records them in a community information master, thereby establishing a community. An information extracting unit transmits the user information of other users who belong to the same community to the information terminal through the web server.

Abstract: It is made possible for a user to set whether to download data used by a program without waiting for the acceptance of a download permission or download the data in response to the acceptance of the download permission via a screen that allows for making the setting for a plurality of programs. An input/output control section (90) accepts, from the user, a setting as to whether to select an automatic download state or a manual download state via a screen that allows for doing so for a plurality of programs. If the setting of selecting the automatic download state is accepted, an item management section (96) downloads the data from a server without waiting for the acceptance of the download permission from the user when a predetermined condition is satisfied. If the setting of selecting the manual download state is accepted, the item management section (96) downloads the data from the server in response to the acceptance of the download permission from the user when the predetermined condition is satisfied.

Abstract: A timing at which communication is to be attempted subsequently is set such that a timing when an information processing apparatus is incommunicatable with a communication counterpart and communication is not carried out is later than a timing when a condition different from the condition that the information apparatus is incommunicatable with a communication counterpart is satisfied and communication is not carried out. When a communication timing comes, if communication with a server is impossible, a timing is set later by a time period than the communication timing as a new communication timing but sets, if a predetermined condition different from a condition that communication with the server is impossible is satisfied, a timing later by a time period, which is shorter than the time period, than the communication timing as a new communication timing.

Abstract: A game device includes an input position acquiring unit and a first game control unit. The input position acquiring unit acquires a position of an entry provided by a player to a touch panel, which can concurrently detect entries at multiple points. The first game control unit displays objects and a sequence in which the objects should be erased on a screen image, and, in case that a position of an entry acquired is at a position corresponding to a position where an object to be erased next is displayed, erases the object from the screen image. The first game control unit includes: a single tap input control unit that, when an input on one object is acknowledged, erases the object; and a multiple-graphic-symbol-tap input control unit that, when inputs on multiple objects are acknowledged concurrently, erases those objects.

Abstract: A driving unit successively selects one drive line from among a plurality of drive lines of a touch inputting device and applies a driving voltage to the selected drive line. A voltage detection unit successively selects one sensing line from among a plurality of sensing lines and detects an output voltage of the selected sensing line. An arithmetic operation unit determines a resistance value of a pressure-sensitive resistive element provided at the location at which the selected drive line and the selected sensing line cross with each other based on the driving voltage and the output voltage. The driving unit applies 0 volts or a bias voltage equal to or lower than the driving voltage to the other drive lines than the selected drive line.
