A driver IC and EML array are electrically coupled to one another via a flexible PCB. The pharmaceutical compositions are topically applied on a patient, and may be provided in a transdermal patch. At the range search step, intermediate patterns are obtained by adding characters in order, one by one, from the last character of the pattern to the first, and a range is determined for a suffix array, which corresponds to the target character string, wherein the first character of each of the intermediate patterns is present. The camera shutter module is used to control the time of the exposure process of the capsule form digital camera. The bottom electrode, the dielectric layer, and the top electrode comprise a cell capacitor.
