Abstract: The present invention relates to a method for detecting changes in the ore grade of a rock face in near real time. The method includes the step of providing a scanning system having at least a hyperspectral imager, a position system, a LiDAR or range determination unit and computational resources. Further, the method involves determining a precise location of the scanning system utilising the position system. The rock face is scanned with the range determination unit to determine rock face position information. The method involves scanning the rock face with the hyperspectral imager to produce a corresponding rock face hyperspectral image. Further the method involves utilising the computational resources to fuse together the rock face position information and the corresponding rock face hyperspectral image to produce a rock face position and content information map of the rock face.

Abstract: The present invention relates to a geological system. The system includes an apparatus for use when scanning an uneven geological surface and that need not contact the geological surface. The apparatus includes a light source for providing light. A reflector is provided for reflecting incident light onto the geological surface, and for reflecting reflected light from the geological surface. The apparatus also includes optical fibre means for receiving the reflected light from the reflector. The system includes moving means for moving the apparatus along the uneven geological surface during scanning. Advantageously, the apparatus does not require physical sampling of material along a hole, and may instead move along the hole at very fast speeds (typically up to between 2 to 4 m/s) whilst obtaining hyperspectral radiometric data. The apparatus may be low cost, and may include no radioactive materials, so that there is little concern or business interruption if it is lost down a hole.

Abstract: A method for processing network data, comprising receiving a data packet at a first processor having a non-transient data memory, storing the data packet in the non-transient data memory, accessing one or more first data fields of the data packet in the data memory, determining whether a device is bandwidth limited as a function of the first data fields being associated with an application, transmitting the data packet to a second processor over a network if it is determined that the device is not bandwidth limited, determining whether the device has reached a limit if it is determined that the device is bandwidth limited, transmitting the data packet to the second processor over the network if it is determined that the limit has not been reached and deleting the data packet without transmitting the data packet if it is determined that the limit has been reached.

Abstract: A tarpaulin support assembly includes a trailer that has a first lateral wall and a second lateral wall. A tarpaulin deploying unit is movably coupled to the trailer, and the tarpaulin deploying unit includes a pair of arms that are each pivotally positioned on a respective one of the first lateral side and the second lateral side of the trailer. Each of the arms is urgeable into a selected angular orientation on the trailer to deploy and retract a tarpaulin over the trailer. A pair of support units is provided and each of the support units is coupled to the trailer. Each of the support unit has a respective one of the arms is pivotally coupled thereto. Moreover, each of the support units is retainable at a selected angular position with respect to the trailer such that each of the arms is supported at the selected angular position. Each of the support units transfers the weight of the tarpaulin into the trailer thereby inhibiting the arms from being damaged.
