A system and methods for collecting and managing air discharged from a melt spinning apparatus. Following this, the level-adjusted received signal is converted into a digital received signal. A therapeutically beneficial low power RF field is generated in the EEG leads merely by the computation and display of the new frequency without the need to deliberately power the EEG leads. The current transaction rate may be compared to the previous transaction rate, and a transaction rate alert may be generated responsive to determining that the previous transaction rate exceeds the current transaction rate.
