  • Publication number: 20220110423
    Abstract: A soft-side container is sized to fit inside larger luggage such as a suitcase. It has a peripheral zipper that aids in compressing the contents of the container when it is loaded, such as with clothing, thereby tending to take less space in the suitcase. It also has a suspension system permitting the container to be hung from a hanger rod, or from another container of the same type, in a cascade of shelves. To aid in this function, the container has an expanding side wall, and also a form-preserving spreader that tends to cause the container to hold itself in a generally planar configuration to function more effectively as a shelf.

  • Patent number: 7257634
    Abstract: A content-aware flow switch intercepts a client content request in an IP network, and transparently directs the content request to a best-fit server. The best-fit server is chosen based on the type of content requested, the quality of service requirements implied by the content request, the degree of load on available servers, network congestion information, and the proximity of the client to available servers. The flow switch detects client-server flows based on the arrival of TCP SYNs and/or HTTP GETs from the client. The flow switch implicitly deduces the quality of service requirements of a flow based on the content of the flow. The flow switch also provides the functionality of multiple physical web servers on a single web server in a way that is transparent to the client, through the use of virtual web hosts and flow pipes.

  • Patent number: 3993934
    Abstract: A method for determining whether an integrated circuit chip containing a plurality of separable circuits is operable when one or more of the separable circuits is not functional.A chip including a plurality of discrete or separable circuits, each of which include means for selectively receiving and distributing a voltage level necessary to render the particular circuit operable, the chip further including a region of one type conductivity at said voltage level common to all of the discrete circuits is tested by a method which will insure that short-circuits between a particular circuit found not to be functional and therefore not to be rendered operable and the common region will not inadvertently apply the voltage level from the common region to voltage receiving and distribution means in the non-functional circuit.All the discrete circuits are first tested to determine which are functional.
