Abstract: The present disclosure presents systems, apparatuses, and methods of evaluating air quality sensor data. In this regard, a method comprises receiving air quality sensor data from a plurality of portable smart air quality measurement system (SAQMS) communication devices from a plurality of citizens in a geographic location; receiving air quality sensor data from an air quality measurement and calibration (AQMC) station in the geographic location; determining a level of resolution for one or more sensors of a portable SAQMS communication device at a central evaluation and measurement service; correcting air quality data received from the portable SAQMS communication device to compensate for the determined level of resolution at the central evaluation and measurement service; and generating a map of air quality data based on at least the corrected air quality data of the portable SAQMS communication device and a plurality of other portable SAQMS communication devices.

Abstract: The current invention pertains to methods of clearing mucus from airways of patients using devices for applying high frequency oscillations to the air passing through the airways of the patients. The devices can comprise a mouthpiece and a high frequency oscillator operably connected to the mouthpiece. The devices create turbulence throughout the airways of the patient from the mouth to the alveoli when the patient breathes through the mouthpiece, thereby clearing the mucus from the airways and helping the patient breathe easily. In certain embodiments, the device is a portable device. In further embodiments, the device is battery operated. In further embodiments, mucus cleared from the airways of patients and/or exhaled breath samples from the patients are collected for analysis and diagnosis during and/or following application of high frequency oscillations.
