Abstract: A technique is disclosed for establishing a secure communication link between a first computer and a second computer over a computer network. Initially, a secure communication mode of communication is enabled at a first computer without a user entering any cryptographic information for establishing the secure communication mode of communication. Then, a secure communication link is established between the first computer and a second computer over a computer network based on the enabled secure communication mode of communication. The secure communication link is a virtual private network communication link over the computer network in which one or more data values that vary according to a pseudo-random sequence are inserted into each data packet.

Abstract: Systems and methods for automatically configuring a distributed antenna system are provided. A configuration sub-system of the distributed antenna system can identify signal parameters for downlink signals received from one or more base stations via inputs of a unit in the distributed antenna system. The configuration sub-system can automatically determine a configuration plan for the distributed antenna system based on the automatically identified signal parameters. The configuration plan specifies how to combine subsets of the downlink signals for routing to remote antenna units of the distributed antenna system.

Abstract: A window assembly comprising a window frame and a window sash is disclosed. The sash is supported on the window frame for pivotal movement between an open position and a closed position. The sash supports an insulated glass unit with an internal blind and includes a primary operator connected to the blind so that linear movement of the primary operator causes movement of said blind. When the sash is closed, a secondary operator supported in the window frame engages the primary operator so that linear movement of the secondary operator causes a corresponding linear movement of the primary operator.

Abstract: Systems and methods are provided for establishing a secure communication link between a first client and a second client. One exemplary computer-implemented method for establishing a secure communication link between a first client and a second client includes accessing, from a storage, identification information of a user of the first client. The method further includes receiving a Domain Name Service (DNS) request from the first client requesting a secure network address corresponding to a secure domain name associated with the second client. The method further includes authenticating the user based on the user identification information. The method also includes transmitting the secure computer network address in response to the DNS request based on a determination that the user has been authenticated. A secure communication link between the first client and the second client is established based on the secure computer network address.
