Abstract: A method for automated control of a drilling operation of a blast hole drilling machine using a down-the-hole drill bit mounted on a drill string is disclosed. The method may include: receiving input data from a user input including information of the drill bit, drill string weight, and desired hole settings; receiving a command from the user to initiate an automatic down-the-hole operation; identifying a location of the down-the-hole drill bit; and using the received input data and based on the location of the down-the-hole drill bit, automatically initiating the steps of: collaring a hole; drilling the hole; and retracting the drill when the hole is drilled.

Abstract: The present disclosure provides systems, methods, and computer-readable media for orchestrating and managing configuration data of network devices and services. In one aspect, a device includes one or more processors and memory. The memory is configured to store computer-readable instructions, which when executed by the one or more processors, cause the one or more processors to obtain configuration parameters of services and devices of a network infrastructure, the configuration parameters having a tree representation, create a copy of the tree representation of the configuration parameters and generate a template having a plurality of matched pattern instances based on the copy of the tree presentation of the configuration parameters, each of the plurality of matched pattern instances being a single representation of configuration parameters for at least two different services or devices of the network infrastructure.

Abstract: An implement system for a machine includes a boom housing a drive mechanism for a cutting implement, and having a plurality of oil outlet ports formed therein. A control mechanism is configured to receive data indicative of an expected change in location of the outlet ports relative to an oil fill line within the boom, and vary a pattern of incoming oil flow to limit entrainment of air in the oil.

A positioning system of the machine includes a control device configured to prevent miscoordination of the gathering head and cutting implement by controlling a position of the gathering head based upon a state of progress of the cutting implement in a cutting cycle.

Abstract: A site positioning system for an underground machine includes a first prism coupled with the underground machine, a second prism operatively coupled with the underground machine, a primary total station, and a reference prism may be in communication with the primary total station. A positioning controller is configured to control, responsive to receiving a High Accuracy Machine Position mode, the primary total station to monitor the first prism and the second prism and transmit a first prism position and a second prism position, respectively, to the positioning controller; control, responsive to receiving a Low Accuracy Machine Position mode, the primary total station to monitor the first prism and transmit the first prism position to the positioning controller; determine, responsive to receiving a Reference Prism Measurement mode, whether a reference prism measurement has been completed, and present positioning information for the machine based on one or more of the prism positions.

Abstract: A control system for a material gathering mechanism includes a gathering head configured to gather material from aground surface, a plurality of gathering members configured to transport the material gathered by the gathering head towards a material conveying apparatus, and a jam detection device for detecting a jam condition in movement of one or more of the plurality of gathering members and generate signals indicative of the jam condition. The control system further includes a controller communicably coupled to the plurality of gathering members and the jam detection member. The controller receives signals indicative of the jam condition from the jam detection device. The controller initiates a sequence of stopping, delaying, and restarting the gathering member on receiving the signals indicative of the jam condition.

Abstract: A control system may be provided for a machine having a swivel chair, a positioning member attached to the swivel chair, a wrist attached to the positioning member, and a cutting head. The control system may include at least one actuator capable of extending and swinging the swivel chair. The control system may also include a lift actuator capable of pivoting the positioning member, a gear mechanism capable of rotating the wrist, and a controller in communication with the swivel chair actuator, the lift actuator, and the wrist actuator. The controller may be capable of determining an excavation pass having a trajectory made from sequential vector paths, and directing the swivel chair actuator, the lift actuator, and the wrist actuator to selectively move the cutting head such that a rotation axis of the cutting head follows the trajectory through each vector path of the excavation pass to form a structure.

Abstract: A control system may be provided for operating a machine having a rotary cutting head. The control system may include a wrist capable of rotating about a wrist axis, a gear mechanism capable of driving rotation of the wrist. A cutting head may be attached to the wrist and capable of rotating about a cutter axis that is substantially perpendicular to the wrist axis. The control system may also include primary and redundant angular sensors capable of generating signals indicative of angular orientations of the wrist. The control system may additionally include a controller, capable of controlling operation of the wrist and the cutting head, comparing an actual angular orientation of the wrist to a target angular orientation, as indicated by the primary and secondary signals, and selectively inhibiting the cutting head from operating when the actual angular orientation differs from the target angular orientation by an operation threshold.

Abstract: An electrical multiple stage switch assembly includes an assembly casing, a first component carrier, and at least one multiple stage switch including a first disc contact, at least one second disc contact, and an actuator. The first and second disc contacts are positioned with their centers substantially aligned, and the first and second disc contact are adapted to flex into an electrical connection when the actuator is pressed and to flex back into a non-electrical connection when the actuator is released. A controlling member includes a controlling part for each switch, and the controlling part includes a spacing member adapted to limit the smallest possible distance between adjacent component carriers.

Abstract: Uncommanded steering detection in a machine can be performed by comparing commanded and actual steering positions of an electro-hydraulic steering cylinder along with a velocity of movement of the cylinder to understand a steering error and whether the actual steering position is moving toward the commanded steering position. A steering error, when above a predetermined threshold, may be cumulatively summed and, if the cumulative sum exceeds a predetermined limit, an alarm may be triggered and the machine may be forced to a safe state (slowed or stopped). The steering error for the actual steering position may be increased if the velocity of movement is not toward the commanded steering position so that the alarm will be triggered sooner. In either case, the response of the machine to steering uncommanded motion will be swifter when the uncommanded motion is more severe (greater error and/or steering in the wrong direction).
