  • Patent number: 10645002
    Abstract: A network sensor that features a data store and a packet processing engine. In communication with the data store, the packet processing engine comprises (1) a cache management logic and (2) deduplication logic. The cache management logic is configured to analyze packets to determine whether (a) a packet under analysis include duplicated data and (b) content of the packet is targeted for storage in a same continuous logical storage area as the duplicated data. The deduplication logic, when activated by the cache management logic, is configured to generate a deduplication reference for insertion into the packet prior to storage.

  • Patent number: 10521358
    Abstract: A network sensor that features a data store and a packet processing engine. Communicatively coupled to the data store, the packet processing engine is configured to (i) generate a retention priority for at least a first flow within a first storage region of a plurality of storage regions and (ii) identify, in response to an eviction request, the priority of each of the plurality of storage regions. The priority of the first storage region is partially based on the retention priority associated with the first flow while the priority of a second storage region is based on retention priorities associated with flows stored within the second storage region. The packet processing engine also is configured to identify, through use of the retention priorities of the stored flows within the first storage region, which flows are to be retained and which flows are to be evicted.

  • Patent number: 10509032
    Abstract: An assay method and device can perform at least one (e.g., at least two) assays on a single aliquot of a sample liquid. The device can mix a sample liquid with assay reagents including magnetically susceptible particles. The device is configured to create a sample liquid-air interface with the sample liquid. The magnetically susceptible particles can be located (via an applied magnetic field) at the liquid-air interface when a second liquid contacts the interface to form a liquid-liquid interface. The magnetic particles travel across the liquid-liquid interface to the second liquid. The magnetically susceptible particles are configured to trans-port an analyte across the interface into the second liquid. An assay for the analyte is performed in the second liquid. An assay for another analyte can also be performed in the sample liquid.
