Navigation logic and related methods are described for assisting a user in using a remote control device. An adsorption unit, located between the higher and lower temperature catalytic converters, adsorbs a portion of the ortho content of the feed stream. The user device generates, based on the user query, commands to be executed by each of the potential applications. Treatments include plasma treatment, irradiation and the application of acids. In some embodiments a threshold may be applied to the data in order to filter out false events.
