Abstract:
1. A system for detecting coatings on at least one transparent or semi-transparent medium, comprising: at least one conductive sensor for detecting a conductive coating without being in contact with the medium, the conductive sensor being configured: to direct an electric field E toward the medium, and depending on whether a signal is detected, to determine whether the coating is made of a conductive material; and at least one light reflection sensor for detecting: i) a non-conductive coating and, ii) a location of one or more coatings on one or more surfaces of the medium, the light reflection sensor being configured: to provide reflection energy magnitude characteristics resulting from one or more surfaces of the medium; the reflection energy magnitude characteristics being compared to reflection characteristics of at least one of: clear glass, transparent material and composite materials; the conductive sensor and the reflection sensor configured to determine a presence of a coating, and if present, determining: the coating location, the coating conductivity, and the type of coating.
