Abstract: An isolation chamber for an optical device can include an enclosure and an inlet port constructed to supply an isolation medium into the enclosure. An exit tube is constructed to direct a stream of the isolation medium out of the enclosure, the exit tube having a length and an inner diameter. The exit tube can extend into the enclosure, the length, the inner diameter and the distance from a lens of the optical device and the exit tube can establish a selected field of view and the exit velocity of the stream of the isolation medium passing through the exit tube at the forward of the end thereof.

Abstract: A controller may receive sensor data from one or more sensor devices of the drilling machine. The sensor data indicates a vertical position of a drilling assembly of the drilling machine. The drilling assembly includes a drill string connected to a drill bit. The controller may determine, based on the sensor data, that the vertical position of the drilling assembly corresponds to a deck wrench engaging position. The controller may cause a deck wrench, of the drilling machine, to engage an engagement portion of the drill string based on determining that the vertical position of the drilling assembly corresponds to the deck wrench engaging position. The engagement portion of the drill string is adjacent to an end of the drill string connected to the drill bit.

Abstract: A system and method for dust mitigation in an environment with high amounts of debris is disclosed. The system may include an optical device disposed within an interior volume of an enclosure. A positive flow of clean air may be maintained into an air input aperture of the enclosure, around the optical device, over a lens of the optical device, and out a lens aperture of the enclosure. The system may be affixed to a piece of equipment, machine, or similar structure via a positionable or pivotable mount.

Abstract: A drilling machine includes an inclination-based levelling system. The drilling machine includes a frame with front and rear portions, and a plurality of support jacks including a pair of rear jacks proximate the rear portion of the frame and a front jack proximate the front portion of the frame. Each jack is extendable and retractable. The drilling machine also includes a sensor configured to monitor and transmit sensor data, the sensor data including at least one of a roll of the drilling machine and a pressure. A controller operatively associated with the sensor, is configured to calculate a volume of debris to be produced during an operation of the drilling machine, to select a machine height setting based on the calculated volume of debris, and to extend and retract the plurality of support jacks according to the selected machine height setting.

Abstract: A method includes receiving a user input to conduct a coarse pivot movement of a drill mast. A locking-pin withdraw signal is sent to a locking pin actuator for a first period of time. Responsive to determining that a locking pin is engaged with a locking hole after the first period of time, the drill mast is repositioned from a current angle to an initial angle. A second locking-pin withdraw signal is sent to the locking pin actuator for a second period of time. Responsive to determining that the locking pin is engaged with the locking hole after the second period of time, the drill mast is repositioned between a minimum drill mast angle and a maximum drill mast angle and sending a third locking-pin withdraw signal to the locking pin actuator for a third period of time.

Abstract: Systems and methods are disclosed for detecting and indicating high-voltage presences on a machine. In one embodiment a high-voltage indication system is disclosed and may include a voltage detector configured to compare the voltage level associated with an element with a threshold voltage value, and provide an indication signal when the voltage level associated with the element is greater than the threshold voltage value. The system may also include an indicator powered by a separate power source independent from the voltage detector. The indicator may be configured to detect the indication signal provided by the voltage detector, and provide one or more warning signals in response to the indication signal.

Abstract: A wire harness testing system is disclosed. The wire harness testing system includes a voltage sensor configured to measure a voltage at a location associated with an electric load, wherein the electric load is connected with at least one wire harness. The wire harness testing system also includes a controller electrically coupled to the voltage sensor. The controller is configured to receive a wire harness test request.
