This invention discloses a modular system having a base module, a mid-section control module, and a display module for preparing and administering a gas-enriched bodily fluid via an extracorporeal circuit. An indication that an external data is to be incorporated into the web page from an external source, such as another web page, is received via an editing interface. The gateway support node can therefore address this network element for connection, and requires reduced own storage capacity. The guitar may include a novel multi-signal guitar pickup that generates some of the analog audio signals. The patterning exposing regions of the substrate between the ICs in which the substrate is plasma etched to singulate the IC and the water soluble material layer washed off.
