  • Publication number: 20230158555
    Abstract: A debris collection and metrology system for collecting and analyzing debris from a tip used in nanomachining processes, the system including an irradiation source, an irradiation detector, an actuator, and a controller. The irradiation source is operable to direct incident irradiation onto the tip, and the irradiation detector is operable to receive a sample irradiation from the tip, the sample irradiation being generated as a result of the direct incident irradiation being applied onto the tip. The controller is operatively coupled to an actuator system and the irradiation detector, and the controller is operable to receive a first signal based on a first response of the irradiation detector to the sample irradiation, and the controller is operable to effect relative motion between the tip and at least one of the irradiation source and the irradiation detector based on the first signal.

  • Publication number: 20220392017
    Abstract: Systems and methods are disclosed to manipulate or normalize image of animals to a reference size and shape. Synthetically normalizing the image data to a reference size and shape allows machine learning models to automatically identify subject behaviors in a manner that is robust to changes in the size and shape of the subject. The systems and methods of the invention can be applied to drug or gene therapy classification, drug or gene therapy screening, disease study including early detection of the onset of a disease, toxicology research, side-effect study, learning and memory process study, anxiety study, and analysis in consumer behavior.

  • Publication number: 20220355904
    Abstract: A push pole attachment for use in manipulation of personal watercraft. The attachment includes a threaded aperture for engagement and attachment to a standard available telescoping handle. An angled element with optional gripping profile can engage a surface of a boat from another surface, or can engage for example the edge of a dock from within a boat—to push and manipulate a boat in the water in relation to nearby objects. A cable hook loop on a rearward surface of the angled element permits a user to hook a cleat on a dock or on the boat surface to pull the boat in as well.

  • Publication number: 20220329531
    Abstract: A packet processing system comprises a packet processing graph comprising classifier nodes including a root classifier node and leaf classifier nodes. The root classifier node is connected to each of the classifier nodes through a respective packet processing path in the graph. Each classifier node stores node match data indicative of at least one match to be applied by the respective classifier node. The classifier nodes comprise first and second classifier nodes arranged in a first packet processing path of said plurality of packet processing paths. The first classifier node stores node match data indicative of a match corresponding to content from a plurality of packet header field types, including first and second, different packet header field types. The second classifier node stores node match data indicative of a match corresponding to content from at least one packet header field type, including the first packet header field type.

  • Publication number: 20220318033
    Abstract: The present disclosure provides techniques for management of user interface elements based on historical configuration data. Use of historical configuration data to render user interface elements improves usability of graphical user interfaces by maintaining a consistent user experience. The states of user interface objects in a hosting environment are retained as historical configuration data and linked to a hosting environment profile. When the same or similar hosting environment is detected, the user interface elements are rendered based on the historical configuration data. For example, the last positions of windows in a particular monitor topology are stored as historical configuration data linked to that monitor topology. The windows are returned to their previous positions when a computing device is next configured with the same or similar monitor topology.

  • Patent number: 11423084
    Abstract: A graph data structure for a packet processing system is generated. The structure comprises graph data objects representing classifier nodes of a packet processing graph. The classifier nodes include a root node and leaf nodes. The root node is connected to each of the leaf nodes through respective corresponding packet processing paths through the graph. Each graph data object includes node match data indicative of at least one match to be applied by the respective classifier node. One or more n-type match graph data objects are identified, which include node match data indicative of an n-type match corresponding to content from n header field types. One or more (n+m)-type match graph data objects are identified, which include node match data indicative of an (n+m)-type match corresponding to a combination of content from a (n+m) different header field types. n and m are integer values of 1 or more.

  • Publication number: 20220261283
    Abstract: The techniques disclosed herein improve existing systems by receiving a packet to process and determining an associated packet processing graph for the packet. In response to determining that the associated packet processing graph contains an action comprising a set of rules for modifying the packet processing graph, a table to modify in the packet processing graph is accessed based on a table identifier in the action. The accessed table is modified by inserting one or more table rows into the packet processing graph and for each inserted table row, inserting a set of template actions containing prepopulated fields. The modified table is used to process subsequent packets.

  • Publication number: 20210274003
    Abstract: Measures for providing timer services in a network including a cluster of nodes responsible for providing timer services to clients. At a given node in the cluster, a request to provide a timer is received from a client. Configuration of a primary replica of the requested timer on a first node in the cluster to pop after a first time has elapsed is initiated. A first timer replication message is transmitted to a second node in the cluster, the first timer replication message indicating that the second node should configure a first backup replica of the requested timer. A second timer replication message is transmitted to a third node in the cluster, the second timer replication message indicating that the third node should configure a second backup replica of the requested timer. Popping of the primary, first backup or second backup timer replicas includes initiating callback of a given client.
