An air-treatment system includes a cooling circuit, a first heat exchanger in thermal communication with the cooling circuit, and a secondary circuit in thermal communication with the first heat exchanger. A received optical signal is converted to an electrical signal. The through hole of the case has an internal diameter size smaller than the external diameter size of the general portion of the inflator near the connection portion of the inflator. The library section is adapted to present depictions of the plurality of template configuration objects to a user via the user interface. A technique is also described for use by an external programmer for pre-calculating comparison matrices so as to reduce the processing burden within the implanted device during posture detection. Communications from terminal station p to each other terminal station in the first direction are assigned one of N1 wavelengths such that no two wavelengths on a given optical fiber are associated with communications between terminal stations in the same direction.
