  • Desktop sharing method and system
    Patent number: 8887063
    Abstract: In a distributed computer network where displayed information is shared between at least two computers, a method of enabling remote control of a host computer having a display region that is to be shared with at least one client computer. The method includes tracking time lapsed since a local user input event has occurred while the host computer is under local control and in the event that the time lapsed exceeds a threshold, enabling remote control of the host computer by a client computer.

  • PLUG-AND-PLAY DEVICE AND METHOD OF USING THE SAME
    Publication number: 20100115145
    Abstract: A plug-and-play device comprises a first plug-and-play interface for establishing a connection with a first computing device and a second plug-and-play interface for establishing a connection with a second computing device. Storage stores code that is automatically executed by the second computing device when the plug-and-play device is connected to the second computing device via the second plug-and-play interface. The code when executed by the second computing device initiates a screen display data exchange between the first and second computing devices through the plug-and-play device. A controller controls the first plug-and-play interface, the second plug-and-play interface and the storage.
