A video transmitting system including a plurality of video cameras, a plurality of video monitoring apparatuses, a plurality of local storage devices, a data transmission subsystem, at least one video data collecting and transmitting apparatus, at least one collecting storage device, and at least one interface apparatus is presented. At this time, a retinal reflex is caused and the luminance in the pupil region becomes high if the eye is a living eye. The stripe height direction is perpendicular to the ABS. The associated subsystem is linked to the storage subsystem via a communication link. In some implementations, the methods include assembling the components while either heated or cooled, taking advantage of thermal expansion and contraction, such that there is a strong interference fit between the components at room temperature. Such a double-plate combiner can especially be applied to a head-up visor mounted in the cockpit of an aircraft, preferably of the airplane type.
