A system and method of configuring value cards which facilitates selection of personalized limits on value card use in transactions. Photons of ultraviolet light are absorbed by the titanium dioxide coating to form reactive hydroxyl radicals that attack and oxidize contaminants in the to water, carbon dioxide, and other substances. Recursive formulas of moment computations for coupled RC trees are derived taking into consideration of both self inductances and mutual inductances. The whisker detection modules can further be coupled with a whisker response system such as an alarm or insulating material dispersing system. Also, if the host application command is a read command, the router transfers data requested by the read command from the target physical location to the host application bypassing the controller. The main amplifier output signal is lower than the replica amplifiers by a factor of.
