AUTONOMOUS is the capacity to make an informed, independent, uncoerced decisions.

FARLITES'^TM IoT Controller, a component of the UVPhasor, proactively reports its status, problems, actions taken, and records activity that is analyzed to project potential future problems and may adjust operating parameters to better provide its services.

FLUX describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance.

A: When we talk, shout, sing, cough, sneeze or simply breathe, we exhale small particles (“aerosols”) that are made of saliva or respiratory fluid (the liquid that wets the inside of your trachea, lungs etc.). These aerosols are the “carriers” of SARS-CoV-2 viruses, and can infect when they are inhaled.   https://tinyurl.com/FAQ-aerosols

A: While the size of an individual SARS-CoV-2 virus is very small (120 nm or 0.12 microns), the aerosol in which respiratory viruses are contained are larger, albeit still small enough to remain suspended in air for long periods. A widely held misconception is that the virus is naked in the air, perhaps with some water. This has been propagated by graphics in major medical journals such as JAMA. Our best guess is that the most common aerosol size is a few microns. Aerosol size has major implications for the ability of masks and filters to remove it from the air, how deeply it will penetrate the lungs, and determines the loss rate due to gravitational settling in indoor spaces.

A:  Second-hand smoke (or vaping) is the best analogy. We are all used to seeing, and smelling, other peoples exhaled smoke, and know that smoke does not fall to the ground quickly.  It is most concentrated right in front of the smoker, and then it is mixed by air currents. In a room with low ventilation, it can build up.  In most indoor environments, a small fraction, e.g., less than 10%, will deposit on indoor materials and the remainder will stay airborne until exhausted to outdoor air.

Now, the virus-containing respiratory aerosols are not visible, because there are far fewer of them than for smoke. But they behave in the air in the same way because they have the same sizes. So you can imagine that others are exhaling smoke, and you want to breathe in as little smoke as possible, especially without a mask. That is how you can reduce your chance of infection.

A: Catching a whiff of exhaled breath here or there is very unlikely to lead to infection. The amount of time you spend in close proximity or in a shared room with an infected person affects how much virus you actually inhale, which will dictate your risk of becoming infected. There is no clear amount of time as far as we know, but it would seem to be in the order of minutes.
