Abstract: A method of operating a cable handling system of a longwall mining machine having a shearer movable along a pan line to mine material along a mine face, the cable handling system including: i) a service line configured to carry one or more supply lines to the shearer for facilitating shearer operation, ii) a plurality of interconnected trays to accommodate the service line, iii) a plurality of sensor nodes distributed along a length of the service line, and iv) a plurality of transceivers distributed along a length of the pan line, the method comprising: a) sensing orientation, acceleration and/or position data of the service line using the plurality of sensor nodes, b) using the plurality of transceivers to receive the orientation, acceleration and/or position data from the plurality of sensor nodes and to transmit the orientation, acceleration and/or position data to a controller, and c) detecting, by the controller, an actual or imminent failure mode of the service line using analysis of the orientatio

Abstract: A method for removing haziness in a digital image is provided. The method includes receiving an input digital image having some haze content from an image capturing device. The input digital image is downscaled to obtain a low-resolution image. Further, a minimum intensity dark channel is determined for each local patch of the low-resolution image to obtain a dark channel image corresponding to the low-resolution image. Furthermore, a transmission map of the low-resolution image is determined based on the dark channel image. Moreover, an atmospheric light value associated with the low-resolution image is also determined. The method further includes applying the determined transmission map and the atmospheric light value associated with the low-resolution image to the input digital image to generate a de-hazed output image and displaying the generated de-hazed output image on a display unit.
