  • Patent number: 11340200
    Abstract: A spray-capillary device is configured to process ultra low-volume samples. The spray-capillary device includes a spray capillary that includes an inlet end and a discharge end. The spray capillary includes a porous section at the discharge end. A downstream connector provides an interface between the porous section of the spray capillary, a conductive fluid, and a high voltage electrical source. The application of voltage to the downstream connector causes electrospray ionization, which can be used to draw ultra law volume samples into the inlet end. A gas injection assembly can be used to increase the pressure on the inlet end of the spray capillary to encourage movement of the sample through the spray capillary. The spray-capillary device is well suited for providing ultra low samples to a mass spectrometer detection device.

  • Patent number: 11303647
    Abstract: The technology disclosed describes a computer-implemented method. The computer-implemented method includes disambiguating a bypassed login event that caused a client to access a cloud application but bypassed a network security system configured to intermediate traffic between the client and the cloud application. The network security system receives from the client an incoming request to access a resource on the cloud application over an application session. The bypassed login event preceded the incoming request. The network security system analyzes the incoming request and detects absence of instance metadata required to determine whether the bypassed login event emanated from a controlled account or an uncontrolled account. The network security system holds the incoming request, generates a synthetic request, and injects the synthetic request into the application session and transmits the synthetic request to the cloud application.

  • Patent number: 11271972
    Abstract: The technology disclosed describes a system. The system comprises data flow logic configured to inject an incoming request directed to a cloud application in a processing path of a particular network security system. The particular network security system is configured to use an application-specific parser to inspect certain fields and variables in the incoming request for metadata, determine that the metadata is missing, and use an application-specific template to construct a synthetic request. The data flow logic is further configured to inject the synthetic request and its corresponding response in the processing path of the particular network security system. The particular network security system is further configured to use the application-specific parser to extract the missing metadata from the corresponding response.

  • Publication number: 20220014593
    Abstract: A discovery system to discover Internet of Things (IoT) resources for a user includes a user client and a server apparatus. The server apparatus determines the user context and establishes a user requirement specification based on the user context and, if provided, on user requirements articulated by the user via the user client. The server apparatus identifies one or more categories of IoT object that match the user requirement specification and interrogates an IoT-object platform to identify IoT resources that correspond to the identified categories. The server apparatus sends the user client information identifying the IoT resource(s) identified by the IoT-object-platform interface. The disclosure also describes a corresponding discovery method, a server apparatus, a method implemented by the server apparatus, a computer program for execution to implement the user client and a computer-implemented method for implementation in a user device to implement the user client.

  • Patent number: 11184403
    Abstract: The technology disclosed describes a system. The system comprises an edge network of a plurality of points of presence of a network security system. Points of presence in the plurality of points of presence are configured to intermediate traffic between clients and cloud applications and to use metadata to apply policies on the intermediated traffic. There are redundancies in metadata synchronization between the points of presence due to metadata migration to a second point of presence from a first point of presence handing off intermediation to the second point of presence within an application session. Each of the points of presence is configured with inline metadata generation logic. The inline metadata generation logic is configured to issue synthetic requests to provide the metadata to the second point of presence without requiring the metadata migration to the second point of presence.

  • Patent number: 10831721
    Abstract: Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. The virtual storage arrays overcomes bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client in the near future. Virtual storage arrays determine the association between requested storage blocks and corresponding high-level data structure entities to predict additional high-level data structure entities that are likely to be accessed. From this, the virtual storage array identifies the additional storage blocks for prefetching.
