  • Patent number: 8219646
    Abstract: Systems and methods for dynamic intelligent mirror selection are presented. Dynamic intelligent mirror selection may include evaluating available mirrors at a client to determine an optimum mirror from which to download a portion of data. For each portion of data downloaded, reevaluation of the available mirrors may be provided such that dynamic selection of the mirrors may reflect changes in network conditions. The mirror selection may be based at least partially on observed characteristics of mirrors observed while downloading from a mirror, such that no synthetic work load is needed to benchmark mirror performance. The observed characteristics may include transfer speed, error counts, latency, and mirror load. Furthermore, a random bonus and usage bonus may be provided to help in facilitating the evaluation of available mirrors.
    Type: Grant

  • Patent number: 6823619
    Abstract: A sign system is disclosed for use with a parking lot which includes a plurality of parking spaces. The sign system comprises at least first and second monuments, a plurality of signs, and at least first and second cable segments suspended between the first and second monuments in a spaced relationship to each other. Each of the plurality signs is disposed adjacent to and bearing indicia identifying a corresponding one of the plurality of parking spaces and is affixed to both of the first and second cable segments in a steadying relationship. The first monument includes first and second weights, each of which is coupled respectively to a corresponding one of the first and second cable segments, whereby tension is applied to each of the first and second cable segments.
