A computer-implemented method for identifying a route that is configured to travel through multiple points of interest includes receiving a query that includes an origin location, a destination location, and at least a first point of interest and a second point of interest. The dispensing element is dimensioned and arranged to cooperate with the plunger head to permit engagement and advancing movement of the dispensing element during corresponding movement of the plunger head without effecting a coupling relationship with the plunger head whereby the plunger is movable toward the retracted position without causing corresponding movement of the dispensing element. The front surface of the substrate comprises at least two device regions separated by at least one dicing lane. The circuit can also achieve a 50% power savings over two-rail versions. The arranging section is made in the inside surface of a single wall of the housing.
