Embodiments of the present invention provide methods and systems for a mobile client device to discover and obtain the parameters of a heterogeneous wireless network via a fuzzy logic operation, within a plurality of heterogeneous wireless networks. The suspension system allows for some axial motion to account for varying system loads. Spatial location information of the transmitter and receiver is collected and associated with each echo sounding. The blade is ultrasonically vibrated to transect and seal the blood vessel. A gas outlet is positioned to receive spent gas from the housing and an ash outlet is positioned remotely from the mixing zone to receive the ash.
