A surface functional electro-textile fabric incorporates energy-active, electrically conductive or optically conductive fibers and nonconductive fibers in a woven or knitted textile fabric. The brush element includes a high-conduction member extending in the longitudinal direction and a low-conduction member bonded to a side of the high-conduction member. In one embodiment of the present invention, certain photocell, are compared to certain photocell, in order to derive a Radial Focus Error signal, by observing radial spot size. The controllers send messages to one or more actuators which effect the change in behavior of the application. The pre-scripted interrogation of the dispatch protocol facilitates uniform and consistent gathering of symptom information relating to a pandemic outbreak.
