A chassis venting apparatus includes a chassis defining a chassis enclosure, the chassis enclosure including a first wall, and a chassis vent structure extending from the first wall and into the chassis enclosure, the chassis vent structure defining a chassis venting passageway in the chassis enclosure. The connection conductor has a tip portion which protrudes from a surface of the second insulation layer and which has a tapered side surface tapering toward an end of the tip portion. In a particularly preferred embodiment of the invention, the neck-protective member of the invention comprises a generally conical neck portion, which fits around the wearer’s neck, and a skirt portion, which fits over the wearer’s shoulders, under the wetsuit. The reconstructed data packets are injected back into the single communication session, and the presence of the original headers in the reconstructed data packets may thereby maintain the endpoint-to-endpoint authentication protocols.
