摘要:
A method and installation (1) of inspecting a fragmentation pattern of a tempered glass panel (2) by deflectometry using the phase-shifting method, following a fragmentation test, the method comprising: (i) positioning the tempered glass panel (2) in contact with a support means (6,7); (ii) projecting thanks to a display device (3) a structured light pattern, such as a fringe pattern, on the surface of at least one portion of the tempered glass panel (2), (iii) capturing an image reflected by the surface of the first portion of the tempered glass panel (2) using an image capture device (4), and (vi) processing the images to determine the fragmentation pattern thanks to an image processing device (5).
摘要:
An electrically heatable glazing panel comprising a substrate and at least a first electrically heatable zone comprising: (i)a substantially transparent, electrically conductive coating layer, (ii) at least a first and a second spaced bus bars substantially parallel adapted to supply electrical voltage across the substantially transparent, electrically conductive coating layer, and (iii) a conductive pathway defined between the at least the first and the second busbars. The glazing panel according to the invention comprises a conductive pathway provided by a pattern of coated and decoated regions in the substantially transparent electrically conductive coating layer of electrically heatable zone to affect the electrical resistivity of the coating in the first electrically heatable coated zone.
