According to an aspect of the present invention, medical devices are provided which comprise: a substrate and bioerodable polymeric layer over the substrate that contains one or more biodegradable polymers, one or more therapeutic agents, and one or more plasticizers. SIM identification information is acquired from each SIM card utilizing corresponding SIM clock signals. The core is moved toward the carcass cord arrangement so that a center axis and an equatorial plane of the core are matched with a center axis and an axial center plane of the imaginary column, respectively. Non-uniformities in a viewer’s perceived intensity distribution from a display surface are corrected by appropriately scaling pixel values prior to transmission to display devices. A stopper is dimensioned to seal the opening.
