Abstract: Described herein are rapid breath testing devices, systems and methods. The device may include a mouthpiece operable to receive air flow from a breath; and a cassette comprising a biosensor and a cassette conduit, the cassette removably connected to the mouthpiece such that at least a sample of the air flow passes through the cassette conduit and over the biosensor. The biosensor may include a plurality of graphene-based sensors and may be operable to detect at least one volatile organic compound in the air flow sample.

Abstract: A multi-dimensional analysis method for operation of a data server to isolate Quality of Service issues to constituents within major or minor Key Performance Indicators.

Abstract: A computer display device is configured to present a plurality of Quality of Service Ratings and link to selectable displays of the component data supporting said Quality of Service Rating. Each Quality of Service Rating is determined by comparing a total combined Quality of Service Score with at least one threshold for a type of service. A method for determining a total combined Quality of Service Score comprises adjusting by an aggregate numerical value for minor Key Performance Indicators from a gross score established among selected major Key Performance Indicators. In an embodiment a ceiling is determined by the lowest rating among the major Key Performance Indicators. A plurality of dimensions and limits determines subsets of wireless communications apparatus. Changes of Quality of Service between subsets are correlated with changes in the data recorded according to a collection profile at each wireless communication apparatus categorized into a subset.
