    Abstract: In an electrically-heated glazing unit including a plurality of collector conductors configured to supply a plurality of heating conductors with an electric current used to heat up the heating conductors and the glazing unit, at least one partial region of the surface of the glazing unit includes an arrangement of parallel heating conductors in which the current flows in opposing directions. The arrangement of the heating conductors in the partial region of the surface is tuned to minimize by mutual compensation or eliminate the magnetic field acting locally within this partial region and perpendicularly to the plane of the glazing unit when the current flows. The operation of an apparatus sensitive to magnetic fields, for example a compass, in the immediate vicinity of the glazing unit thus becomes more reliable.

    Abstract: In a laminated glass sheet with a fixing device introduced into a through-hole for objects, particularly for antennas, the through-hole is made up of holes of different sizes in two rigid sheets of the lamination, and the fixing device includes at least two parts introduced into the through-hole, pressing against surfaces around the edge of the through-hole, which surfaces are situated one facing the other. The two parts of the fixing device press from both sides against the surfaces around the edge surrounding the smaller hole made in the sheet, in that region of the walls of a smaller hole that exhibits an edge compression stress that is increased by heat treatment by comparison with the remainder of the surface of the sheet.

    Abstract: An electrode is produced on a rigid or flexible support substrate, including a grid network of very fine electrically-conductive lines with nodes and links, to produce a diffraction pattern, as much as possible in an arc shape, in the light transmitted and that results in an absence of high-level optical impacts. The grid network may in addition be produced without preferential direction with a number of three lines joining up at each node and/or with conductive sections extending in the shape of an arc or in wave form between the nodes.
