Each micro electrode of a high-density micro electrode array is connected to the same conducting wire. The radar detects a distance from the automobile to the front object, and the camera takes an image of the object. The liquid flow rates and a total combined flow rate of the fluid mixture\u2014determined based on a differential pressure of the fluid mixture through a given area\u2014enable resolving a gas flow rate. The system also has a fiber remover which removes fibers deposited along the exterior surface of the datum. with hydroxide at a maximum reaction temperature of about T65 C. The corresponding method for scouring released vaporous Hg housed within a container includes providing a source of carbon carrying between about 5% and 15% sulfur, basis carbon weight, reacted with between about 0.
