  • Patent number: 8255973
    Abstract: Systems and techniques are provided for controlling requests for resources from remote computers. A remote computer's ability to access a resource is determined based upon the computer's operating environment. The computer or computers responsible for controlling access to a resource will interrogate the remote computer to ascertain its operating environment. The computer or computers responsible for controlling access to a resource may, for example, download one or more interrogator agents onto the remote computer to determine its operating environment. Based upon the interrogation results, the computer or computers responsible for controlling access to a resource will control the remote computer's access to the requested resource.

  • Patent number: 8255854
    Abstract: A method for reducing delay in an integrated circuit by compensating for differences in rise and fall delay times comprises creating a timing graph; computing minimum delay tuples for nodes in the timing graph; if there is not at least one feasible delay tuple, determining a longest path and computing minimum delay tuples for the longest path; changing polarities on the longest path to reduce delays; updating the timing graph by transferring new polarity and delay values; performing timing analysis to determine a new longest path if the new longest path is shorter than the prior longest path, accepting a resulting polarity selection and computing minimum delay tuples for the longest path; if the new longest path is not shorter than the prior longest path, accepting a resulting polarity selection and implementing changes in a user-program bitstream.

  • Patent number: 8235817
    Abstract: Embodiments of the present invention provide a library of video related to game play involving the use of particular objects. By observing game play of users in a game play environment, determinations may be made as to users who excel at the use of a particular object. Video of game play related to these users and a particular object may be created, cataloged, and stored for later use by users that lack proficiency with that object. By observing video of game players with particular skill as to an object, less skilled players may improve their game play thereby avoiding frustration with a game, which may lead to a loss of interest. Acquisition and proffering of video may be facilitated through the use of an analytics server or functional software module that observes game play and identifies players of particular skill or lack thereof.

  • Patent number: 8217843
    Abstract: A device for a wireless RF link to a remote receiving device can radiate at different radiation patterns in response to detecting a change in the device position. As the device is moved, displaced, or re-positioned, a position sensor in the device detects the change in position and provides position information to a processor. The processor receives the position information from the position sensor, selects an antenna configuration and physical data rate based on the position information, and provides an RF signal associated with the selected antenna configuration through the antenna elements of the selected antenna configuration.
