Abstract: Described herein are techniques, devices, and systems for using a machine learning model(s) and/or artificial intelligence algorithm(s) to optimize testing of components of a system operated by a wireless carrier. For example, data generated as a result of executing a first test of a suite of tests may be provided as input to a trained machine learning model(s) to classify one or more tests of the suite of tests as having a particular characteristic. A to-be-executed test may be classified as likely to pass or likely to fail when executed, for example. An already-executed test may be classified as reliable or unreliable, as another example. Based on the classification of the test(s), the suite of tests may be modified to optimize testing of the wireless carrier's system.

Abstract: An automated wire insertion machine for inserting wires into grommet cavity locations of an electrical connector includes a controllable wire insertion robot and a processor to generate pre-generated plug maps based upon an original plug map of the grommet cavity locations and to control the wire insertion robot based upon one pre-generated plug map to insert the wires into the grommet cavity locations. The pre-generated plug maps are generated by defining a range of potential error of the grommet cavity locations that includes at least one of a potential rotational error and a potential translational error, defining an acceptable tolerance of the grommet cavity locations that includes at least one of an acceptable rotational tolerance and an acceptable translational tolerance, and calculating offset values of the grommet cavity locations based on the range of potential error and the acceptable tolerance, thereby generating the plurality of pre-generated plug maps.

Abstract: An embodiment includes a robotic welding system for generating a motion program, having a programmable robot controller of a robot having a computer processor and a computer memory. The programmable robot controller is configured to digitally record, in the computer memory, a plurality of spatial points along an operator path in a 3D space taken by a calibrated tool center point (TCP) of the robot as an operator manually moves a robot arm of the robot along the operator path from a start point to a destination point within the 3D space. The programmable robot controller is also configured to identify and eliminate extraneous spatial points from the plurality of spatial points as digitally recorded, leaving a subset of the plurality of spatial points as digitally recorded, where the extraneous spatial points are a result of extraneous movements of the robot arm by the operator.

Abstract: A method utilizes a funnel system and robotic end effector grippers to feed an unjacketed portion of a shielded cable through a sleeve. The funnel is designed with one or more thin extensions (hereinafter “prongs”) on which a sleeve is placed prior to a cable entering the funnel. Preferably two or more prongs are employed, although a single prong may be used if properly configured to both guide a cable and fit between the sleeve and cable. The prongs close off the uneven surface internal to a sleeve and provide a smooth surface for the cable to slide along and through the sleeve, preventing any damage to the exposed shielding. The sleeve is picked up and held on the prongs using a robotic end effector. If the sleeve is a solder sleeve, the robotic end effector has grippers designed to make contact with the portions of the solder sleeve that are between the insulating rings and the central solder ring.

Abstract: In a service mesh, back-pressure is applied and relieved as needed by a control mechanism which is applied between pairs of services to control the rate at which service requests are made from one of service to the other via monitoring hardware and/or software metrics. A proxy of one service is monitored to observe the rate at which it receives service requests from the other service. If it is observed that the monitored metrics have breached allowable limits, back-pressure is applied to reduce the rate at which the other proxy transmits these service requests. Through continued monitoring of the proxy, the back-pressure can be later relieved when appropriate by increasing the permitted request rate.

Abstract: A computer system hosting (micro)services that uses a service mesh to govern communication between the services. The services include consumer services and an event stream service, the latter directing an event stream from a producer service to the individual consumer services. The control plane of the service mesh has the role of creating and removing service instances. Based on a specified event capacity that is to be provided by the consumer services collectively, the control plane manages service provisioning by estimating the current event capacity of the system. This is done by measuring the event capacities of each consumer service instance and summing them, from which any shortfall or excess of the current event capacity in relation to the specified event capacity can be determined. Consumer service instances are then added in case of a shortfall or removed in case of an excess as needed to avoid over or under-provisioning.

Abstract: Methods and apparatus for temporarily holding one end of a wire on a harness form board during automated transfer from one robot to another robot. The apparatus includes a wire holding device which is designed to facilitate the transfer of a wire end from a first end effector of a first robot to a second end effector of a second robot. The wire holding devices have different structures, but share the common feature that opening of the wire holding device (to enable wire insertion) involves applying a contact force which overcomes a spring force that urges the wire holding device to be closed. The end effectors are designed and their movements are controlled in a manner such that the moving end effector applies the contact force necessary to overcome the closure-inducing spring force being exerted.

Abstract: Various embodiments comprise systems and methods to indicate when errors occur in a data pipeline. In some examples, data monitoring circuitry monitors the operations of a data pipeline. The data monitoring circuitry ingests an output data set generated by the pipeline, compares the output data set to an expected output, identifies differences between the output data set and the expected output, and determines when the magnitude of the difference exceeds an error threshold. When the error threshold is exceeded, the data monitoring circuitry generates a graphical representation of the output data set, a graphical representation of the expected pipeline output, and an animated transition from the graphical representation of the expected pipeline output to the graphical representation of the output data.

Abstract: Various embodiments comprise systems and methods to determine entropy in strings generated by a data pipeline. In some examples, data monitoring circuitry monitors a data pipeline that ingests input data, processes the input data, and responsively generates and transfers a data string that comprises character groups.

The data monitoring circuitry determines a probability distribution for the numbers, calculates entropy for the data string based on probability distribution, and generates an entropy histogram based on the entropy. The data monitoring circuitry compares the entropy histogram of the data string to another entropy histogram for another data string, determines a change in entropy, and reports the change in entropy.

Abstract: Various embodiments comprise systems and methods to monitor operations of a data pipeline. In some examples, a data pipeline receives data inputs, processes the data inputs, and responsively generates and transfers data outputs. Data monitoring circuitry monitors the operations of the data pipeline circuitry, identifies an input change between an initial one of the data inputs and a subsequent one of the data inputs, and identifies an output change between an initial one of the data outputs and a subsequent one of the data outputs. The data monitoring circuitry correlates the input change to the output change, determines a quality threshold for the output change based on the correlation, and determines when the output change falls below the quality threshold. When the output change falls below the quality threshold, the data monitoring circuitry generates and transfers an alert that indicates the input change and the output change.
