Devices and methods are provided for reducing client node power consumption when monitoring first and second channels corresponding to first and second access nodes in a heterogeneous wireless-enabled communications environment. The socket is connected to the mounting member, which is pivotably secured to the housing and constructed to allow rotation of the socket, and thereby a lighting element engaged with the housing, relative to the housing. The map displays the neurons with their relevance identified by any of font type, color, transparency and font size. The support is divided into marked zones and mark-free zones. Etch away the exposed portions of the conductive metal layer below the C4 solder bump openings to form through holes in the conductive metal layer exposing C4 solder bump plating sites on the top surface of the base below the C4 solder bump openings with the conductive metal layer remaining intact on the periphery of the through holes at the C4 solder bump plating sites.
