  • Patent number: 7953893
    Abstract: Disclosed herein is a method and system, in which a network entity determines that an HTTP response destined to a client station contains a markup document that references at least one object but that the HTTP response does not contain the object. In response, in addition to sending the HTTP response to the client station, the network entity will send to the client station a supplemental HTTP response that contains the object, without the client station sending a request for the object. By avoiding the need for the client station to send a request for the object, the extent of HTTP communication by the client station is reduced. In the situation where the client station is a wireless handset or other wireless communication device, the method is particularly advantageous, as the method can reduce the number of air interface communications and can thus help to conserve valuable air interface resources.

  • Patent number: 7941550
    Abstract: A method, system, and computer readable media are provided for managing multiple HTTP cookies that are present in a wireless communication system. When a secure or non-secure HTTP cookie is formed, a time of creation for that HTTP cookie is also created as part of the cookie header. Therefore, when a wireless device makes a subsequent communication to a web based server, the gateway compares the creation time for multiple HTTP cookies that are present, and only forwards the most recently created HTTP cookie to the web based server. This avoids invalidating a session as a result of receiving multiple conflicting HTTP cookies from the same wireless device.

  • Patent number: 7930421
    Abstract: Media, methods and systems are provided for coordinating changes of network sources for media streams in a telecommunications network. The streams communicate instances of media content via packets to devices. A first network source streams packets of an instance of media content to a device. Each packet includes information regarding the temporal ordering of that packet within the instance and information regarding the sequencing of the packet within the stream. It is determined that a second network source should stream the instance of media content. A point in the temporal ordering within the instance is identified and communicated at which the second network source will provide the instance of media content. The second network source streams to the mobile device the instance of media content from the identified point, without requiring adjustment of the information regarding the sequencing of the packets within the stream.

  • Patent number: 7526342
    Abstract: Apparatus and surgical methods establish temporary suction attachment to a target site on the surface of a beating heart for analyzing electrical signals or hemodynamic responses to applied signals at the target sites for enhancing the accuracy of placement of cardiac electrodes at selected sites and for enhancing accurate placement of a surgical instrument maintained in alignment with the suction attachment. A suction port on the distal end of a supporting cannula carries surface-contacting electrodes and provides suction attachment to facilitate temporary positioning of the electrodes in contact with tissue at the target site, and a clamping and release mechanism to facilitate anchoring a cardiac electrode on the moving surface of a beating heart at a selected site. Analyses of sensed signals or responses to applied signals at target sites promote epicardial mapping of a patient's heart for determining optimum sites at which to attach cardiac electrodes.

  • Patent number: 7497865
    Abstract: A ring for use in anastomosis. Preferably, the ring is integrally formed from metal, and includes a ring portion and tines and docking members that extend from the ring portion. The ring portion and tines are malleable, and preferably also the docking members are malleable. The ring portion and tines are malleable in the sense that once deformed from a first shape into a second shape, they will not relax back into the first shape from the second. To install the ring in a vessel with the ring portion extending around an incision or other orifice, the tines pierce the tissue around the orifice and are curled against an anvil. The action of curling the tines inverts the tissue near the orifice edges to expose the inside surface of the vessel or organ.
