A hybrid communications system implements different communication technologies to communicate data and information for particular communications directions in different portions of the system. In one embodiment, the rotor includes a plurality of curved directing walls disposed between first and second braking surfaces to define a plurality of flow channels. A non-flowable gel is provided in the cushioning pad. The socket is preferably compliant with AGP and VIP standards. Furthermore, the full color EPDs of the present invention are capable of displaying high contrast images of high color saturation. These surfaces are adapted to sealingly clamp therebetween the sealing area of the pipe, when the insert is mounted into the plug hole.
