The present invention provides methods and systems for an ion generator mounting device for application of bipolar ionization to airflow within a conduit, the device includes a housing for mounting to the conduit having an internal panel within the enclosure, and an arm extending from the housing for extension into the conduit and containing at least one opening. Encrypted management key is obtained using the key management information and index information. The outputs of the storage cylinders are connected through a plurality of differential air pressure valves to a fill station, to cause the storage cylinders to fill up individual air breathing tanks, in which the storage cylinders are depleted in a determined sequence, one at a time. In some embodiments, a flexible cable extends out from the headmount at an acute angle relative to a horizontal plane of the headmount, to optimize strain relief as the subject moves about while attached to any stimulation, monitoring andor recording equipment.
