A reversible ratchet wrench includes a handle from which a head extends. The master controlling device securely controls an operation executed by the microprocessor, core or processing unit through the private network to the additional private network connection via the secure control bus. Each alternatorinverter section provides a 120 VAC output, and a 240 VAC output is formed between the two alternatorinverters sections. The soft bits are generated by a combination of a first modulation of voltage on a current word line WLn and a second modulation of voltage on an adjacent word line WLn+1, as in a reading scheme known as \u201cDirect-Lookahead \u201d.
