In the construction of a P-well area formed with a pair of CMOS inverters and a N-well area that constitute a multi-port SRAM cell, the P-well area is divided into two P-well areas. This includes both the primary reference signal, and a plurality of redundant duplicate signals, substantially identical in all respects to the primary reference signal except in relation to magnitude and phase, for the purpose of unfolding, or opening the audio signal content into layers that result in an omni-directional acoustic signal, representing the sound as it would behave in nature. This lens system device that can be placed into an in situ cataract provides for a much simpler surgical technique and reduces related pre and post operative procedures and potential complications. A first sealing device serves to seal lapped edges of the tubular film so as to form a lengthwise sealed portion.
