The invention discloses methods of making and uses for wide spectrum disinfectants including as components an alcohol, O-phenylphenol, chlorhexidine gluconate, nonoxynol-9, benzalkonium chloride, and deionised double distilled water wherein on a weightvolume ratio the alcohol comprises from 50 to 80%, the O-phenylphenol comprises from 0. Further, provided is an electrochemical device using the proton conductor such as a fuel cell or the like. for detecting slow and rapid earth deformation, by making use of a recursive filter having the filter characteristic adapted to a detected type of motion. This apparatus and method is also applicable for antenna selection in the case of a single cell with a plural number of geographically separated antennas. The second conductor is formed in a manner to be in electrical communication with the first conductor.
