An improved apparatus and method are disclosed, for pumping fluids, such as water andor hydrocarbons, from a subterranean formation or reservoir, through use of a cranked rod pumping apparatus for imparting reciprocating substantially vertical motion to a rod of a sucker-rod pump having a pump stroke. The server management system includes a plurality of motherboards, a baseboard, a bus, a first and a second sensor. At the lower level, individual vision and audio trackers can be designed to generate effective proposals for the fuser. The determinator is based on the first absolute maximum mask signal, the first absolute summation carrier signal, the second absolute maximum mask signal and the second absolute summation carrier signal to accordingly determine that the carrier mode is of a multi- or single-carrier mode.
