  • Patent number: 11086356
    Abstract: Embodiments of the present application provide a foldable support device, including: a driving component and a support component connected with the driving component; and a rotating gear and a rack intermeshing with each other and connected with the driving component and the support component. The driving component and the support component are disposed on a non-display surface of a flexible display panel; and the flexible display panel is folded or unfolded with intermeshing rotating and relative moving of the rotating gear and the rack. By setting the rotating gear and the rack, when the flexible display panel is folding, the rotating gear rotates along the rack and drives the support component to move away from the driving component. Sufficient storage space is generated for the flexible display panel while folding to effectively prevent the display failure caused by folding of the flexible display panel.

  • Patent number: 8799515
    Abstract: A network device implements an SSL VPN gateway for client devices. The network device may receive a script destined for a client device. The script may include at least one later binding uniform resource locator (URL)-based link entity. The network device may rewrite the script to include additional script associated with the later binding URL-based link entity. The additional script is configured to execute at the client device to rewrite the later binding URL-based link entity with substitute links that refer to the network device. In this manner, the network device allows the external client devices to access back-end servers in a proprietary network without requiring the installation of custom software on the client devices.

  • Patent number: 8201238
    Abstract: In general, techniques are described of enabling a client-based web browser application to browse a directory structure provided by a server on a private network via a secure gateway. In particular, an intermediate gateway device is positioned on a network path between the client device and a server device. The gateway device communicates with the client device via a secure network connection (e.g., a Secure Sockets Layer connection). When the gateway device receives a resource identifier that identifies a directory structure from either the client device or the server device, the gateway device alters the resource identifier. In particular, the gateway device alters the resource identifier in such a way that when the client device transmits a request to view the directory structure identified by the resource identifier, the client device transmits a request to view the directory structure in a networking protocol that the gateway device permits to pass through the gateway device.

  • Patent number: 8132242
    Abstract: In general, the invention is directed to techniques of automated authentication of network-enabled software applications launched by a web browser. For example, an intermediate device, such as a Virtual Private Network (VPN) gateway, intercepts communications between a client device and a server. The gateway device automatically issues a temporary token to the client device when the web browser requests a resource that will result in the launch of an additional software application external to the web browser. This temporary token is only valid for a limited time and a limited number of uses. Subsequently, the gateway device uses the temporary token to authenticate the second software application, thereby avoiding passing user credentials from the web browser to the second application on the client device via an insecure persistent cookie.
