The present invention discloses a blends of an aromatic polyimide polymer and a polymer containing aromatic sulfonic acid groups that can be converted into polybenzoxazole membranes for gas, vapor, and liquid separations. In particular aspects, the atomization means communicates with a remote particle filter member configured and positioned to provide for particle size filtering. A channel decoder is coupled to the inner receiver, decoding the equalizer output to generate a data sequence.
