A method of reconstructing a damaged sequence of symbols where some symbols are missing is provided in which statistical parameters of the sequence are used with confidence windowing techniques to quickly and efficiently reconstruct the damaged sequence to its original form. The multi-size catheter comprises an outer diameter defined by a plurality of superimposed peelable layers. The method is based on changing thermodynamic state properties of ambient airborne wind passed through a convergent-divergent system. Accordingly, the evaporated fuel treating capability of the canister can be exerted higher than in the system in which the flow rate of evaporated fuel is not regulated. The system may be calibrated by using a laser or other sensor to mechanically measure the amount of movement. The align key may have a protrusion formed in a center thereof.
