A source roll having a first layer of liner paper and a second roll of two-sided adhesive is fed through a pair of rollers having six aligned rotary die cutters sized to cut through only the adhesive layer. In one embodiment, a method includes sensing a signal indicative of cardiac pressure, measuring a height of the sensed signal at a peak amplitude of the sensed signal, and measuring a duration of the sensed signal. In certain embodiments, the resulting accuracy and CPU time reduction are a result of a Green’s function approach with the correct quasi-static limit, a modified discrete complex image approximation to the Green’s function, and a continuous dipole expansion to evaluate the magnetic vector potential at the distances relevant to VLSI interconnects and intentional inductors. In certain embodiments, query views may be based upon associations present within the business layer, rather than upon database-level entities that are typically relied upon in conventional query creation. The one or more support member may be laterally displaced relative to the rotation axis of the rotatable selector.
