A sealing assembly for extending around a rotating shaft for preventing the transmission of fluids along the shaft, in which a sealing element is biased towards the rotary sealing part; and a pusher sleeve extends between the sealing element and a housing. The method includes positioning an IR transmissive material in a reactor chamber of a parallel plate plasma reactor and thereafter depositing a hydrogenated amorphous germanium carbon film on a surface of the IR transmissive material. The module synchronizes its activation interval based on a coordinated time base signal. The low-profile, narrow single shoulder pass-through permits fluid communication for both inflation and deflation between the front and back chamber portions, but does not restrict the wearer’s neck or shoulder range of motion.
