A leafing leather cover of cellular phone and a smart phone using the same are described. An oxygen sensor includes an outer connection terminal having an outer fitting portion, an extension portion extending inwardly from an axially intermediate point of the outer fitting portion and pulling prevention portions and formed on rear end parts of the outer fitting portion at positions adjacent to the extension portion. A combined image is displayed of a superposition of the data sets, and a determination is made as to whether the combined image indicates an adequate registration between them based upon the extracorneal eye feature data in the two data sets. Preferably, a stencil having a decorative cut-out pattern is also inserted into the chamber between the cosmetic pad and the amount of cosmetic powder whereby, upon the application of pressure within the chamber, an amount of cosmetic powder is drawn through the stencil and embedded into the cosmetic pad. The die may have features to facilitate placement of the interconnects such as dogleg cuts, grooves, notches, enlarged contact pads, tapered side edges and stepped vias.
