Abstract: Disclosed herein is a method for producing a multi-layer coating on a substrate including the steps of (i) forming a primer coat layer (P) on a substrate, (ii) forming a silver metal layer (S) onto the surface of the coating layer (P); and (iii) forming one or more clear top coat layers (T) onto the surface of the silver metal layer (S), where the primer coat layer contains one or more particulate components selected from the group consisting of matting agents and structuring agents and where the silver metal layer (S) is formed by reductive deposition from an aqueous alkaline ammoniac solution containing a soluble silver salt, by use of a reducing agent. Further disclosed herein are multi-layer coated substrates obtainable according to the above method.

Abstract: To monitor a degree of attentiveness for a driver of a vehicle, a period is determined on the basis of a speed of the vehicle. It is determined whether an eyelid closed time and/or an eyelid closing time of the driver exceeds the period.
