Abstract: Systems and methods are disclosed for mapping search nodes to a search head in a data intake and query system based on a tenant identifier in order to execute a query received by the data intake and query system. The mapping may allow same or similar search nodes to be used to execute queries that are associated with a particular tenant identifier, in order to take advantage of caching and local data stored with those search nodes. In some cases, search nodes can be mapped based on the tenant identifier using a hashing algorithm, such as a consistent hashing algorithm.

Abstract: Systems and methods are disclosed for annotating a metadata catalog in a data intake and query system based on a query received by the data intake and query system. The metadata catalog can store information about datasets associated with the data intake and query system, including dataset configuration records of the datasets, which can be used to process queries for execution by the data intake and query system. The data intake and query system can receive a query identifying a set of data to be processed and a manner of processing the set of data. The data intake and query system can parse the query to identify datasets and/or data fields associated with the query. Based on the identified datasets and/or fields, the data intake and query system can generate one or more annotations, and use the annotations to update the metadata catalog.

Abstract: Systems and methods for multi-thread processing of messages. An example method comprises: receiving, by a first processing thread, a plurality of network packets from a server; processing the plurality of network packets to produce a message; writing the message to a message queue; retrieving, by a second processing thread, the message from the message queue; producing a memory data structure based on the message; placing the memory data structure into a result queue; and responsive to determining that a total size of messages in the message queue exceeds a certain threshold, causing the first processing thread to suspend receiving network packets.

Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. The data intake and query system receives a query identifying a set of data to be processed and a manner of processing the set of data.

The identified configuration parameters are communicated to a query processing component of the data intake and query system for use in executing the query.

Abstract: A surgical console has a receptacle for receiving a surgical fluidics cassette. The receptacle has a light source that transmits light to light pipes in the surgical fluidics cassette. The light pipes transmit light to a light transmissive optical interface surrounded by an opaque frame in the surgical fluidics cassette. The opaque frame is located at a fluid level detection system in the cassette. The system illuminates fluidic connectors on the surgical fluidics cassette without interfering with the fluid level detection system of a surgical console.

Abstract: Systems and methods are disclosed for dynamically assigning a search head or search nodes in a data intake and query system for a query received by the data intake and query system. Existing search heads and search nodes can periodically report their status to the data intake and query system, which can use that information to help determine the need to provision additional search heads and search nodes. The data intake and query system can receive a query identifying a set of data to be processed and a manner of processing the set of data. The data intake and query system can use the status information for existing search heads and search nodes to dynamically assign a search head and search nodes for the query. Dynamically assigning the search head and search nodes in this manner may provide many benefits, including improved load balancing and resource utilization.

Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. The data intake and query system receives a first query identifying a set of data to be processed and a manner of processing the set of data. The data intake and query system parses the first query and uses a dataset association records of a metadata catalog to dynamically identify one or more datasets associated with the query and generate a second query. The data intake and query system executes the second query.

Abstract: An ophthalmic surgical system includes a robotic arm disposed above a patient's eye. A positioning camera is disposed on the robotic arm and positioned to visualize the patient's eye. A processor is electrically coupled to the positioning camera. The processor is configured to receive an indication of a position of the robotic arm relative to a fixed datum, determine a focal length between the positioning camera and the patient's eye, compare the focal length to the position of the robotic arm, and determine a patient eye level relative to the fixed datum.

Abstract: Systems and methods are disclosed for processing and executing queries in a data intake and query system. The query identifies a set of data to be processed and a manner of processing the set of data. The data intake and query system dynamically identifies a plurality of containerized search nodes instantiated on one or more computing devices in a containerized environment to execute the query. The data intake and query system executes the query using the containerized search nodes.

Abstract: Ophthalmic surgical systems and methods for displaying graphical user interfaces in ophthalmic surgical systems are disclosed. An example ophthalmic surgical system has alternative setup conditions, and a host computer is configured to detect the setup condition and to display on a display screen a graphical user interface corresponding to the detected setup condition. The alternative setup conditions may be based upon a configuration of an ophthalmic surgical console and/or based upon which type of fluidics cassette is installed on the ophthalmic surgical console. In some embodiments, the host computer is configured to display on the display screen a graphical user interface that graphically indicates the instrument ports that are available and/or that are not available for instrument connections in the detected setup condition.

Abstract: Systems and methods are disclosed for interfacing with one or more components of a data intake and query system.

Abstract: Disclosed are a joint manipulation device and system for increasing the range of motion of a joint of a user, and monitoring the compliance of the user's operation of the joint manipulation device to standards or guidelines set by a monitoring entity. Certain sensors associated with the joint manipulation device may cause an indicator to transmit an alert to the user based on whether or not the device is sufficiently engaged with a limb or joint of the user to be considered in compliance. Additionally, progress data associated with the range of motion of the user's joint may be obtained by a sensor assembly and transmitted to one or more systems associated with the device system. Progress data obtained during a period of non-compliant use of the device may be excluded from the transmitted data, thereby generating a set of compliant progress data for accurate analysis of device effectiveness.
