A window including deliberate rupture zones. The window is obtained by a method whereby the glass is subjected to local overheating of the structure using a high-energy beam penetrating the glass, deliberate rupture zones are produced by sequentially guiding the beam in a predetermined path along the preferred path for the window to break along, and by sequentially focusing the beam both along the predetermined path and at various depths relative to the surface of the window. The sequential focusing at various penetration depths follows a line that is inclined and/or curved relative to the normal to the surface of the glass so that a weakened structure is created in the window to obtain rupture behavior of the window that differs according to the direction in which the influence leading to rupture acts.

Glazing comprising break lines

The subject of the invention is an electrically controllable device comprising at least one substrate provided with a functional stack of layers comprising at least two active layers separated by an electrolyte. The stack is placed between a lower electrode and an upper electrode. The device comprises n regions which are independently electrically controllable, using the lower electrode having a pattern A in one or two dimensions, the stack of layers, at least one of the active layers and the electrolyte of which having a pattern B in two dimensions, the upper electrode having a pattern C in two dimensions, so that the superposition of the patterns A, B and C, defines said n regions, with a physical discontinuity between two adjacent regions at least both at the level of the upper electrode and at the level of one of the active layers and of the electrolyte.
