An inline pipe filter and an air conditioner including the same. The outer flowpath section surrounds at least a portion of the inner flowpath section and is spaced apart therefrom to define a passageway having an air inlet. In other forms the present invention provides recursive filtering for joint iterative decoding in a variety of systems and functions such as linear multiple access channel decoders, iterative equalisation, iterative joint channel estimation and detectiondecoding, iterative space-time processing, iterative multi user interference cancellation and iterative demodulation. The network device connects the incoming call from the calling device to the particular mobile device when the categorization of the incoming call is important. In another embodiment, internal regulation signals are shared with other devices via TSVs. The method comprises providing a template-containing molecular sieve, heating the molecular sieve under conditions effective to remove a portion of the template from the molecular sieve, and cooling the heated molecular sieve to leave an amount of template effective to cover catalytic sites within the molecular sieve.
