A weldable component is described. The method and apparatus detects variations in the voltage and frequency of the grid. The lift mechanism is operated by a pneumatic cylinder which is powered by an on-board compressed air tank. The compounds are drugs or intermediates to drugs. In a non-limiting exemplary scenario, the first memory module and the second memory module may be communicatively coupled to the decoder module with independent respective data andor address buses. If a contaminant induced electrical fault occurs in the selectively protected electrical system, the electrical fault is more likely to occur in the un-encapsulated controller, such that the selectively protected electrical system is disabled.
