  • Patent number: 8433795
    Abstract: An example embodiment of the present invention provides a process that uses IP flow information to selectively notify users of an application server of the server's unavailability. In the example embodiment, the process, which might run on a system comprising a router, monitors IP flow records as to dropped packets and learns that an application server has become unavailable. The process then uses the IP flow records to identify active users of the application server, for example, by passing a source IP address to a presence service. Once the process has identified an active user, the process determines a means of notification for the user, which might be through the presence service, and transmits a notification to the user as to the unavailability of the application server. In the example embodiment, the process transmits a later notification as to the availability of the application server, using reverse camp-on functionality.

  • Publication number: 20120059214
    Abstract: An active hydraulic ventricular attachable support system includes a net cover for surrounding a ventricle and is formed by hollow tubes. All the hollow tubes can completely communicate with each other or form a plurality of independent areas, and the interior of each independent area is intercommunicating, while the independent areas are not communicating with each other. The system as a whole is positioned on the surface of the heart. The hollow tubular structure can be filled with various kinds of liquid of different physical characteristics, and then the corresponding reaction pressure generated can be applied to the ventricle and the surfaces of the heart. The system also can be incorporated with local administration.
