According to one embodiment of the invention, the descrambler IC comprises a local memory to store a unique key and a plurality of process blocks. An audio signal is received in a base domain and then transformed into a non-base domain, such as cepstrum domain or LP residue domain. Well structural data and well production data are combined therewith to generate a real-time display of down-hole well operation, including animated graphics of the pump operation, including pump movement, rod and tubing stretch, fluid movement, gas compression, system forces, and fluid pressures. When the windings are electrified, the stationary part generates a magnetic field which interacts with the permanent magnetic poles to reciprocate the movable part relative to the stationary part in a second direction perpendicular to the first direction. The electrolyte salt contains lithium salt A and lithium salt B.
