  • Patent number: 9112875
    Abstract: A system and method for efficient and private peer-to-peer file sharing consists of ascribing a uniquely identified and anonymous link (an “edgelink”) to any file or set of files on a peer computer. The link is registered with a publishing server along with continuously updated connectivity information about the peer without registering any identifying information about the file. A peer recipient is able to access the link, receive connectivity information about the publishing peer from the server, and then receive the file from the publishing peer without file content passing through the server, mediating any intermediary NAT devices without requiring any manual or automatic device reconfiguration.

  • Patent number: 8945880
    Abstract: The thermal cycling system for performing a biological reaction at two or more different temperatures comprises: a) a heat source for setting at a fixed temperature; b) a reaction vessel containing material upon which the biological reaction is to be performed; c) mechanically-operable structure for altering the relative position of the heat source and the reaction vessel so that reaction vessel first achieves and maintains a desired first temperature in the reaction vessel for starting the carrying out of the biological reaction, and then for altering the relative position of the heat source and the reaction vessel so that the reaction vessel then achieves and maintains a second temperature for continuing the carrying out of the biological reaction on the biological material, and d) temperature-sensing structure operatively associated with the reaction vessel for controlling the altering of the relative position of the heat source and the reaction vessel so that the reaction vessel achieves and maintains the
