A muffler is integrally incorporated into the rear housing of a compressor. The device is supported at one end by a support structure and the other end is capable of being connected to the ship’s manifold. The transmission address modes use different bits to transmit the address information respectively. The second fluid sequentially intersects a series of targets along the channel wall as the second fluid flows through the channel. Methods of making and using the substantially non-reflective, low or non-fluorescing substrate are also disclosed.
