A electrical connector system comprising a plug assembly and a socket assembly. The ESD protection circuit includes a plurality of active devices formed in the semiconductor substrate, the active devices being formed by a process including a plurality of steps carried out to form, at the same time, a plurality of active devices having a function other than ESD protection. At least one channel is established comprised primarily of free-electrons which provide a path of least resistance for the transmission of energy therethrough. In alternative embodiments, the retainers remain with the buttress material after being stapled to tissue. The resilient can also be arranged as required by the type of exercise and for convenience.
