Abstract: A path selection unit selects a network communication path from a plurality of available network communication paths for transmitting data from a hybrid network device to a destination network device. A packet transmit unit determines path connection characteristics associated with the selected network communication path. The packet transmit unit generates a hybrid network packet for transmitting the data to the destination network device based, at least in part, on the path connection characteristics associated with the selected network communication path. The packet transmit unit transmits the hybrid network packet to the destination network device via the selected network communication path.

Abstract: Soft decision sections (503, 506) provisionally decide each modulated signal (502, 505) separated using an inverse matrix calculation of a channel fluctuation matrix at separation section (501). Signal point reduction sections (508, 510, 514, 516) reduce candidate signal points of a multiplexed modulated signal using the provisional decision results (504, 507). Soft decision sections (512, 518) make a correct decision using the reduced candidate signal points and obtain received data (RA, RB) of each modulated signal. This allows received data RA, RB with a good error rate characteristic to be obtained with a relatively small number of calculations without reducing data transmission efficiency.

Abstract: A method and system are disclosed that can be applied to achieve high-throughput in a WLAN. Central to the present invention is the use of an SDMA compatible multi-beam antenna system by a WLAN access point. A system based on two types of antennas-dynamic beam forming and fixed beam antennas—is described. A mechanism and protocol are described that implement simultaneous transmissions with respect to an SDMA compatible access point and thereby improve spectral efficiency, and by extension achieve higher throughput. Based on the recognition that current WLAN MAC has major limitations in throughput, certain MAC extensions (that can be applied independently of SDMA) are described. Also disclosed are power-saving and power control techniques that improve battery performance and contribute to a reduction in station size, and a means of reducing channel interference. The present invention also deals with the problem of backward compatibility with conventional devices that implement the protocol that is a subset covered by the present invention.

Abstract: Systems and methods provide a discovery protocol allowing nodes that are interested in knowing a network topology to discover other nodes in the network topology. The discovery protocol includes two message types, topology discovery messages and topology query messages. A node issues topology discovery messages upon powering up, at periodic intervals, or upon detecting a change in network topology. The topology discovery messages are broadcast to all nodes on a network and identify the issuing node to the network. A topology query message is sent to a particular node and requests a response from the receiving node regarding the neighboring nodes of the receiving node. The querying node can use the response data to discover other nodes and to send the discovered nodes query messages such that the node can determine a network topology to a desired level of depth within the network.

Abstract: A method of playing an interactive baseball-related card game, comprising the steps of: dealing each of nine outcome cards to each of the players, wherein each of the outcome cards is based upon the likelihood of a particular event occurring during a plate appearance by a batter; arranging, by each player, each of the outcome cards based upon a predicted outcome of the plate appearance of the batter by that player to create an outcome card lineup, wherein the outcome cards are arranged such that a most likely outcome of the plate appearance of the batter, as predicted by that particular player, is placed at the top of all of the outcome cards in that particular player's outcome card lineup; monitoring the plate appearance of the batter; determining an actual outcome of the plate appearance of the batter; reviewing each of the player's outcome card lineups to determine which player is the winning player for the plate appearance by the batter by determining which player has a correct outcome card that corresponds to the actual outcome and which of the players with the correct outcome card has the correct outcome card located closest to the top of all of the outcome cards in that particular player's outcome card lineup; determining how many outcome cards the winning player discards based upon the actual outcome of the plate appearance; and determining a winner of the interactive baseball-related card game.
