The invention relates to a signal processing method which optimizes the bit error rate under pragmatic conditions. The modifying agent is a halogen-free compound hydrolyzable to an oxide selected from the group consisting of silica, alumina, titania, zirconia, niobia, and mixtures thereof; or a sol selected from the group consisting of silica, alumina, titania, zirconia, niobia, and mixtures thereof. An implant delivery system can include a distal guidewire port for receiving the proximal end of the guidewire. The measurement device associated with the automated inspection station is configured to examine the different medications and generate a measured medication value for the different medications. A second end of the electrical wiring terminates at an electrical plug adapted for connection to an electricity source.
