  • Patent number: 11469090
    Abstract: The invention generally relates to apparatuses for focusing ions at or above ambient pressure and methods of use thereof. In certain embodiments, the invention provides an apparatus for focusing ions that includes an electrode having a cavity, at least one inlet within the electrode configured to operatively couple with an ionization source, such that discharge generated by the ionization source is injected into the cavity of the electrode, and an outlet. The cavity in the electrode is shaped such that upon application of voltage to the electrode, ions within the cavity are focused and directed to the outlet, which is positioned such that a proximal end of the outlet receives the focused ions and a distal end of the outlet is open to ambient pressure.

  • Publication number: 20220291451
    Abstract: Optical fiber connections and their applications in downhole assemblies are described herein. The downhole assembly includes a well completion element with an end that couples with a corresponding well completion element. An optical fiber extends along at least a portion of the well completion element and transmits an optical signal using a first mode. The well completion element includes an optical fiber connector that is coupled to the optical fiber. The connector also includes a mode converter that receives the optical signal from the optical fiber and converts the optical signal from the first mode to a second larger mode. This second larger mode may be more robustly communicated to a corresponding optical fiber connector affixed to the corresponding well completion element.

  • Patent number: 11444838
    Abstract: Techniques are disclosed for query processing system that can, when queried, generate a result related to one or more connectivity paths and/or one or more network security rules. Network security rules and connectivity paths may be stored in corresponding data structures (e.g., sets of attributes) that may be utilized with a number of set operations. The user may issue a query requesting the system to apply a rule to a path, a set of rules to a set of paths, to identify if one set of rule(s) are equivalent to another set of rule(s), and the like. Utilizing this query processing system can enable a user to identify effects of one or more network rules with respect to traffic being allowed or restricted along particular connectivity paths between components of the system.

  • Patent number: 11444837
    Abstract: Techniques are disclosed for network policy verification system that can obtain a set of connectivity paths of a containerized environment that individually indicate connections between pairs of containers. Identify a first container and a second container of a pair based at least in part on a connectivity path. Determine a network policy corresponding to the connectivity path that indicates an expected result of that particular connection. A connection can be initiated between the two containers. The result may be presented at a user device based at least in part on identifying that the result is different from the expected result indicated by the network policy corresponding to the connectivity path.

  • Publication number: 20220263835
    Abstract: A computer system may receive one or more requests for access to one or more cloud services and may store the one or more requests in a request log. The computer system may receive one or more access rules applicable to cloud service access rights. The computer system may aggregate the one or more requests of the request log to determine access requirements for a container, the container being configured to store one or more applications. The computer system may generate and store container access policies that define access of a container and the one or more cloud services, the container access policies based at least in part on the aggregated one or more requests and the one or more access rules. The computer system may send the container access policies to a request forwarder of a compute instance in a production environment.
