Aspects of the present disclosure are directed toward methods, systems and apparatuses that include a main printed circuit board with first-type sensor circuitry and another printed circuit board with second-type sensor circuitry. A remote monitoring system may track andor control activity at the plurality of player terminals. The lithium-nickel-manganese composite oxide is represented by the molecular formula LiLixNiyMnzO2-a where: 0<x <0. This may include selections of one or more characterizations of the same process by at least two members.
