Grammars for interactive voice response systems using natural language understanding can be created using information which is available on websites. The methods and apparatuses may be further implemented to determine whether the mobile device is located in at least one of the two or more regions based, at least in part, on a comparison of the two or more determined variations. The interference filter includes a plurality of high and low refractive index layers, both of which alternately stacked. This tab area is cleared of active material and reinforced with a reinforcing material and a conductive tab is welded to the thus treated area resulting in an electrode plate having a strong integrated tab assembly. The present invention allows the user to simultaneously select the scale while moving the range over different portions of the data field.
