A gaming network is disclosed which includes point to point cabling infrastructure connectable to at least one first gaming machine and connectable to at least one second gaming machine. In certain embodiments of the invention, coded probes comprising a probe molecule attached to one or more nano-barcodes may be allowed to bind to one or more target molecules. The front wall varies in thickness and has a bulging area of increased thickness on its inner surface. The method involves using a differential signal splitting followed by a common mode voltage normalization stage, then a controlled gain transimpedance amplification, and then amplification using one or two rail to rail amplification stages that are symmetrical and balanced in nature. Properties for the return types are identified and key fields are identified for indexing.
