Abstract: In certain embodiments, a mine personnel carrier includes an integrated information display and one or more processing units. The processing units may access life support data from devices associated with a life support subsystem of a mine personnel carrier. The life support subsystem provides breathable air to passengers of the mine personnel carrier, and the life support data indicates a remaining level of air available via at least a portion of the life support subsystem. The processing units access guidance data from guidance devices associated with a guidance subsystem of the mine personnel carrier. Each guidance device can detect entities within a detection range of the guidance device. The processing units initiate display in the integrated information display of at least a portion of the life support data and the guidance data. The integrated information display comprises a unified electronic display of the mine personnel carrier.

Abstract: A method for the emplacement of a sensor in soil for sensing seismic activity comprising in one embodiment the steps of creating a borepath in the soil, the borepath having opposing ends and a diameter, inserting a longitudinal housing and a grout pipe into the borepath extending from one of said opposing ends to the other, the longitudinal housing having the sensor encapsulated within, the grout pipe having one end and a grouting end, pulling the grout pipe longitudinally within the borepath by the one end to position the grouting end between the opposing ends within the borepath, and conducting a grout through the grout pipe into the borepath at the grouting end to encase the longitudinal housing within the borepath thereby facilitating emplacement of a sensor in soil for sensing seismic activity. The grout preferably selected so to acoustically match the longitudinal housing to the soil.
