  • Publication number: 20210005990
    Abstract: A multichannel connector assembly includes a plug connector comprising an insulation body, a plurality of conductive terminals, and a shield housing enclosing outside the insulation body, and a socket connector comprising an insulation base, a plurality of docking terminals housed in the insulation base, and a shell enclosing outside the insulation base. The shell includes an inter-buckling portion elastically deformable and provided with an inter-buckling protruding portion and an inter-contacting protruding portion. The inter-buckling protruding portion is capable of engaging with an opposite connector, and the inter-contacting protruding portion is capable of forming a grounded potential connection to the opposite connector by elastically deforming. A ring side portion provided by the shield housing, the base portion and the side end portions provided by the insolation body encircle to form a cut-off region where the conductive terminal soldering portion is arranged.

  • Publication number: 20200019693
    Abstract: A system and method are described for performing authentication on a computing device using a mobile device connected over an audio channel to the computing device, in scenarios where smart card authentication may have been traditionally used. An application executing on the computing device receives a request from a user, which request requires authentication of the user before being allowed by the application. An audio transmission containing encoded data including information authenticating the user is received at the computing device from the user's mobile device via a microphone. The audio transmission is decoded and the information authenticating the user is extracted. The information authenticating the user is verified and the request is allowed in the application.

  • Patent number: 10447656
    Abstract: A VPN tunnel policy is defined on a per-application basis. The VPN tunnel policy may specify that a particular application is permitted to transmit data on a specific VPN tunnel. Subsequently, the specified application is delivered to one or more virtual machines and an application tunnel manager creates a new virtual network interface card (NIC) on the VM, corresponding to the delivered application. The newly created virtual NIC is attached to a specified subnet. The subnet may be a VPN transition network with a connection to a VPN gateway device. The subnet may have been previously defined or generated at the time of assigning the application to the VPN tunnel. Once the virtual NIC has been created on the VM, an OS script is executed to force the delivered application to use the newly created virtual NIC and to prevent users from changing the application and virtual NIC linkage.

  • Publication number: 20190230188
    Abstract: Embodiments of the present disclosure relate to techniques for providing a remoted application to a client device over a network. Certain embodiments involve receiving, by a web server and from the client device, a request for the remoted application. The request may comprise a tag which identifies one or more attributes of the remoted application. Embodiments further involve launching, by the web server and based on the tag, the remoted application. Embodiments further involve providing, by the web server and to the client device, a video stream of the remoted application. The video stream of the remoted application may comprise one or more images rendered based on raw data of the remoted application. Embodiments further involve receiving, by the web server and from the client device, user input and providing, by the web server and based on the user input, application input to the remoted application.

  • Publication number: 20190222559
    Abstract: One or more VPN tunnels are established in a site-to-site configuration. A VPN transition subnet is defined and associated with each VPN tunnel. Once the VPN tunnel(s) and the LAN(s) have been configured, a per-application VPN policy can be specified for any applications that require site-to-site VPN access. Whenever a new application is launched, a container is created for executing the VM. The VPN management system reads the VPN policy to determine whether the application is permitted to access any VPN tunnels. If the application is permitted to access a VPN tunnel, a vNIC is generated on the VM for the container of the application and/or a new IP address on the vNIC is assigned to the container. The new IP address and/or the new vNIC are then added to the VPN transition subnet associated with the VPN tunnel to enable the application to access the VPN tunnel.

  • Publication number: 20080006934
    Abstract: A flip chip package generally includes a substrate, a flip chip die, and a heat spreader. The flip chip die is coupled to the substrate. The heat spreader is coupled to the flip chip die. The heat spreader can include one or more walls. Generally, the one or more walls at least partially laterally surround the flip chip die and/or the substrate. The walls can completely laterally surround the flip chip die to define a cavity in the heat spreader. The flip chip package can further include an encapsulate. For example, the encapsulate can be injected between the one or more walls of the heat spreader and the flip chip die and/or other components of the flip chip package. The encapsulate and/or the one or more walls of the heat spreader can protect one or more components of the flip chip package against moisture, corrosives, heat, or radiation, to provide some examples.

  • Publication number: 20060065972
    Abstract: A cavity or die down ball grid array package includes an interposer substrate structure attached to the die. In an example, the interposer substrate reduces the interconnect length from a board to which the package mounts to power and ground pads on a top layer of the semiconductor or integrated circuit (IC) die. In this example, the interposer substrate also removes the requirement that power and ground pads be located on a periphery of the die. Power and ground pads can be located in an interior region on a top metal layer where they can be interconnected to the interposer substrate using electrically conductive bumps or wire bond(s).
