A vehicle window glass which is capable of preventing a film formed on a surface of a glass plate from peeling off to thereby improve the appearance quality of an edge portion of the glass plate. The system of the invention comprises the manufacturer of the device and an enrollment authority. The conditioned signal is up-converted and transmitted back to the automotive radar system to determine if the automotive radar provides accurate readings for distance, size and speed. By being detachable, the mechanical trigger may be transported and stored separate from the pyrotechnic igniter thereby improving the overall safety of the fire suppression system. The raised edge regions each form a lateral fastening portion for attachment to the upper strapping material.
