Abstract: A laminated glazing for a vehicle windscreen comprising first and second sheets of glazing material joined by a sheet of adhesive interlayer material is described. The laminated glazing has an outer facing surface and an inner facing surface comprising a first treated region that has been subjected to a roughening process such that before the roughening process the first treated region has a first surface roughness and after the roughening process the first treated region has a second surface roughness. The first treated region having the second surface roughness helps the laminated glazing break when subject to an impact on the outer facing surface. Use of a roughened region to reduce the time taken for a laminated glazing to break upon being impacted by an impactor is also described.

Abstract: Methods of making a laminated glazing having reduced optical distortion when installed in a vehicle are described. The laminated glazing has first and second sheets of glazing material each separately shaped between a pair of shaping members that are then laminated together. The position for bending the first sheet of glazing material may be deliberately offset from the position for bending the second sheet of glazing material. During the lamination step, the first sheet of glazing material may be displaced relative to the second sheet of glazing material by a lateral and/or longitudinal positional displacement. The first and/or second sheet of glazing material may have been cut such that after lamination at least a portion of the peripheral edges thereof are aligned. Apparatus for shaping a sheet of glazing material for carrying out the aforementioned methods is also described, as is a resulting laminated glazing.

Abstract: The invention relates to a heatable glazing comprising an electrically conductive coating and a data transmission window. The data transmission window comprises a plurality of grids made by ablations in the electrically conductive coating and at least one break line between adjacent grids. At least one of a width “a” of the grids and a distance “b” between adjacent grids is selected to maximise transmission of a predetermined frequency of electromagnetic radiation and to reduce the formation of hot spots. Preferred embodiments conform to a standard size of an ERTICO window and a frequency range from 5 GHz to 6 GHz.

Abstract: Laminated vehicle glazing with a conductive panel defining slot antennas between the conductive panel and the metal surround of the vehicle with connecting leads, and a camera or other device in an area where the device and the antenna do not overlap. Locating the device in a different position to the slot antenna reduces the electromagnetic interference that the slot antenna experiences and prevents malfunction of the device where the slot antenna is used to transmit radio signals.
