A vision display system for a vehicle includes a plurality of cameras having exterior fields of view, a first display screen disposed in an interior rearview mirror assembly of the vehicle, and a second display screen disposed at or in a console or instrument panel of the vehicle. The method and system include collecting set of digital training images including a set of states for the set of digital training images. Each emulsion contains an amino-functional polyorganosiloxane having a certain minimum content of nitrogen. Strips that are substantially perpendicular to the flow direction direct heat from the heater to the sides of the membrane, causing a large proportion of the heat that would otherwise drive heat flows to be dispersed and decreases inaccuracies or bias in the measured flow rate.
