  • Patent number: 8150470
    Abstract: A system and method for improved data transmission on a wireless link to a remote receiving node includes a communication device for converting packets to RF at a physical data rate, an antenna apparatus having a plurality of antenna configurations for transmitting the RF, and a processor for selecting the antenna configuration and the physical data rate based on whether the remote receiving node indicated reception of the data transmission. The processor may determine a table of success ratios for each antenna configuration and may rank each antenna configuration by the success ratio. The processor may transmit with an unused antenna configuration to probe the unused antenna configuration and update the table of success ratios. Similarly, the processor may maintain a table of effective user data rates, rank each physical data rate by the effective user data rate and probe unused physical data rates to update the table.

  • Patent number: 8142289
    Abstract: Client position in a multi-client game is determined using dead reckoning. Clients send information to a server over a network. The server distributes this information to other clients. A client uses this information and dead reckoning to determine a character's position. The server may calculate the client's position using dead reckoning and send updates to clients when errors between actual and calculated positions exceed a threshold. Clients may calculate their position according to dead reckoning, and when an error between actual and calculated position exceeds a threshold, send updated information to other clients. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

  • Patent number: 8140405
    Abstract: The subject invention relates to electronic buying and selling systems and methods. In particular, the invention concerns relations among distinct price curves, price curve attributes (i.e., factors of the offer that can affect the price curves) and buyers or potential buyers. For instance, a price offered to a system user can vary based on total volume of all people aggregating in private environments, cumulative total order by user, ship date, optimal time, as well as terms and conditions associated with the offer (e.g., no cancellation of order, cancellation possible, payment method . . . ).

  • Patent number: 8140402
    Abstract: Mechanisms are provided to facilitate buying and selling products utilizing social pricing. Sellers initiate sale of a product with volume discounts for a limited time. In other words, the more people that buy a product, the lower the price for the group. Buyers have a real incentive to become prosumers that not only purchase a product but also promote purchase by others. A social pricing system brokers interaction between sellers and buyer groups, and provisions mechanisms to aid promotion of products by consumers utilizing social networks and other online activities.

  • Patent number: 8136143
    Abstract: A scalable access filter that is used together with others like it in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Each access filter use a local copy of an access control database to determine whether an access request made by a user. Changes made by administrators in the local copies are propagated to all of the other local copies. Each user belongs to one or more user groups and each information resource belongs to one or more information sets. Access is permitted or denied according to of access policies which define access in terms of the user groups and information sets. Access is further permitted only if the trust levels of a mode of identification of the user and of the path in the network by which the access is made are sufficient for the sensitivity level of the information resource.

  • Patent number: 8131802
    Abstract: Systems and methods of the present invention for maintaining network data distribution are provided. Network data may be distributed in such as manner as to allow a network session to weather interrupted communications between host and clients without significant loss of data. Embodiments of the present invention provide for one or more clients to serve as backup host(s) for the network session. When the other clients transmit data to the host, they may also transmit the data to one or more backup hosts if there are any indications of interrupted communication.

  • Patent number: 8125975
    Abstract: An access point of a communications network is configured to receive a multicast or broadcast packet from a source. The access point converts the multicast or broadcast packet into a unicast packet addressed to a station associated with the access point. The access point then transmits the unicast packet over the communications network from the access point to the station. The access point further may determine a minimum data rate by which the access point may transmit the multicast or broadcast packet to the station and determines an effective unicast rate for transmitting the unicast packet to the station. If the effective unicast rate does not exceed the minimum data rate, the access point does not transmit the unicast packet to the station and transmits the multicast or broadcast packet.

  • Patent number: 8117645
    Abstract: A new approach to network security includes manipulating an access point such that an initial communication from an external device is passed to a restricted subset of a computing network including a gatekeeper. The gatekeeper is configured to enforce a security policy against the external device before granting access to a less-restricted subset of the computing network. If requirements of the security policy are satisfied, then the gatekeeper reconfigures the access point such that further communication from the external device may be received by elements of the less-restricted subset. Enforcement of the security policy optionally includes performing a security audit of the external device.
