A system that includes a memory, a memory card, a processor, and a power supply is provided. The cutting insert includes an insert body having a bottom surface extending in a first plane, and a body axis extending substantially in parallel with the first plane. The local ring couples one or more of the ADNs and transmits optical signals to and from the ADNs. The exemplary BPR can be use at either constant pressure or to generate pressure programs where the pressure is varied versus time. The organic material layer is etched and patterned by using a layer of the photoresist patterns which are shrinking as an etching mask, thereby shrunk mask patterns are formed which have mask sizes smaller than those of the photoresist patterns before being shrunk. In one arrangement, an optical connector housing holds the optical interface in an optical interface location of the optical connector housing, and a film positioning assembly selectively positions windowed and non-windowed sections of film over the optical interface location in order to selectively expose and protect the optical interface.
