Abstract: An eye alignment monitor and method are described for the detection of variability of the relative alignment of the two eyes with each other, thereby detecting deficits of binocular function, for use as a screening device for these abnormalities especially in infants and young children. Each embodiment includes means for tracking of the positions of a subject's two eyes simultaneously, and furthermore includes repetitive calculation of the relative positions of the two eyes with respect to each other. The embodiments do not require fixation by either eye on a specific point. Typically, a movie on a video display is used for viewing by the subject. Variability of relative alignment of the two eyes with each other is typically determined by variability of the relative positions of images of the pupils of the eyes with respect to each other over time.

Abstract: Method and arrangement for adjusting nitrogen and oxygen concentrations within regions of an aircraft. The method includes separating nitrogen from ambient air onboard an aircraft thereby establishing a high-concentration nitrogen supply and then dispensing high-concentration nitrogen from the supply to a fire-susceptible, non-habitable region of the aircraft where the high-concentration nitrogen is reservoired thereby decreasing the capability for the atmosphere therein to support combustion. Oxygen is also separated from the ambient air thereby establishing a high-concentration oxygen supply that is dispensed to an occupant cabin of the aircraft thereby increasing the level of oxygen concentration within the cabin to a level greater than the naturally occurring concentration of oxygen at the experienced internal cabin pressure.
