The present invention provides a system andor method that facilitates expanding keywords within an existing computer programming language by employing a whitespace keyword containing embedded whitespace. Signal response features similar to those used in pulsed eddy current techniques are applied to conventional eddy current methods. The facility identifies in the received text sequence a reference to a distinguished product. The method further performs one or more tests to evaluate the feasibility of the current line profile and each of the target line profiles, and then transitions the state to operate the DSL line in the highest feasible profile available. A method for applying the illuminator to an object is also disclosed.
