Certain embodiments of the present invention provide a cable manager. In a pre-conditioning step, high voltage discharges and optionally with highly ionizable gas injections are applied to a system of borehole electrodes, causing the formation to fracture with disintegration in multiple directions but confined between the locations of electrode pairs of opposite polarity. An envelope may be detected with respect to each of the sensors, and signals within each envelope may be separated. The electronic devices includes transistors, resistors, capacitors, among other types of devices. The at least one connector is arranged to permit translational movement of the container from the first position to the second position more slowly than from the second position to the first position.
