20150247888 | SPARK TESTING APPARATUS - The invention provides a method and apparatus for electronically testing the safety of sources of energy such as electrical circuits, in explosive atmospheres such as high risk mining situations, using an electronic spark tester (EST) in place of the known mechanical spark test apparatus (STA). The EST typically uses an analogue subsystem ( | 09-03-2015 |
20140000967 | FLUID DRILLING HEAD WITH SLIDING GAUGING RING | 01-02-2014 |
20130319773 | FLUID DRILLING HEAD NOZZLE DESIGN - A fluid cutting head of the type having a plurality of nozzles in a rotatable nozzle assembly for cutting a bore hole in rock. The cutting head has nozzles arranged to be supplied with high pressure drilling fluid, forming jets positioned to cut adjacent rock. The nozzles include one or more generally axially facing pilot nozzles, and one or more generally radially facing reaming nozzles. At least the pilot nozzles include a non-tapering outlet section such that the jet issuing therefrom is of substantially constant cross-section in a zone immediately adjacent the outlet section. The pilot nozzles are located in a leading part of the rotatable nozzle assembly, and have a minimized diameter. The reaming nozzles are located in the following part of the rotatable nozzle assembly. The following part of the rotatable nozzle assembly is formed in a step-wise fashion to keep the reaming nozzles close to the rock face. | 12-05-2013 |
20130231855 | COLLISION AVOIDANCE SYSTEM AND METHOD FOR HUMAN COMMANDED SYSTEMS - A method of implementing an optimal avoidance filter for interposing between a human operator issued movement commands and a corresponding machine control system of a movable machine, for the avoidance of collisions with objects. The method: includes inputting a detailed representation of objects in the vicinity of the movable machine; and formulating a hierarchical set of bounding boxes around the objects. The hierarchical set including refinement details depending on the current positional state of the movable machine, with objects closer to the machine having higher levels of refinement details. The method further includes utilizing the resultant hierarchical set as a set of constraints for a mixed integer optimisation problem to determine any alterations to the issued movement commands so as to avoid collisions with any objects. | 09-05-2013 |
20120074931 | FLOW TRACKING IN BLOCK CAVING MINING - The invention provides a method and system for monitoring the flow of ore in block cave mining operations by inserting an active magnetic beacon | 03-29-2012 |

20100145217 | SCALP POTENTIAL MEASURING METHOD AND APPARATUS - An apparatus for measuring scalp potential is disclosed, which comprises a plurality of sensors and a pre-amplifier coupled to these sensors. The sensors are adapted to measure a raw scalp potential measurement though a hair and air interface, and may be considered as a difference, reference or common measurement. The interface presents a high and variable source impedance coupling to the scalp. The pre-amplifier is adapted to have an input impedance significantly higher than that presented by the source interface, and receives the raw scalp potential measurement to produce a pre-amplified scalp potential measurement. | 06-10-2010 |
20100036645 | COLLISION AVOIDANCE FOR ELECTRIC MINING SHOVELS - Systems and methods for reducing the probability of a collision between a first object, whose trajectory is substantially controlled by an operator input command, and a second object. In one embodiment such a method includes receiving an operator input command indicative of first control data; generating model data indicative of a virtual construct of the physical environment proximal to the first object; processing the first control data to predict future dynamics of the first object in the environment; determining whether, on the basis of the predicted dynamics and the model data, the first object is predicted to collide with a second object in the environment; defining second control data for which the first object is not predicted to collide with the second object in the environment; and providing the second control data to a controller coupled to the first object such that the first object is controlled in accordance with the second control data for substantially avoiding the collision of the first object with the second object. | 02-11-2010 |
