    摘要: The invention provides an optical multiplexing device comprising: a plurality of optical sources with integrated collimators (31-37) whose output beams are combined by mirrors (41-47) or other beam deflecting elements, which combine the beams into a single composite beam diverging from a common origin point (30). This is done by arranging the mirrors (41-47) staggered at different distances from the origin point, and at different angles to each other taking accourt of the dependence of the beam divergence in far field on the distance from the origin point.

    摘要: A risk engine device of an enterprise's authentication system is configured to apply a Bloom filter algorithm to a master authentication list from a database to generate the Bloom filtered authentication list. Once generated, the risk engine device stores the Bloom filtered authentication list as part of an associated cache memory. Because the Bloom filtered authentication list is smaller in size relative to the master authentication list, by utilizing the Bloom filtered authentication list, the risk engine device decouples the linear dependency between the master authentication list and cache memory consumption, thereby reducing the relatively excessive cache memory use found in conventional risk engines.
