An irrigant comprising either a hypochlorite compound or a chlorhexidine compound in combination with at least one surfactant and preferably two or more surfactants, including fluorosurfactants, ethoxylates, sulfonates, quaternary ammonium compounds, amine oxides, and combinations thereof, wherein each of the surfactants are capable of complexing with one another. High end position forces on the bevel discs in their end positions are limited, yet the entire control range of the bevel discs may be used. The synthesis tool is used to optimize the circuit, under the applied constraints, so that the circuit exhibits certain desirable timing properties, while at the same time minimizing hardware cost and various other properties. The method may further include performing a search of a database for information associated with the object, and receiving results of the search.
