GLASS EMERGENCY SYSTEM Russian patent published in 2019 - IPC G08B13/04 B32B17/06 

FIELD: glass.

SUBSTANCE: invention relates to emergency system (10, 10') of glasses. Glass system includes: at least one first glass (1) consisting of prestressed glass having outer surface (I) and inner surface (II), at least one transparent electroconductive coating (3), which is located on inner surface (II) of first glass (1), sensor unit (20) having capacitive sensor (21), which is connected by capacitive coupling to transparent electroconductive coating (3), wherein sensor unit (20) with deviation of measurement signal of capacitance sensor (21) from comparative value supplies an alarm signal, wherein capacitance sensor (21) comprises exactly one measuring electrode (21.1), or measuring electrode (21.1) and base electrode (21.2), or measuring electrode (21.1), basic electrode (21.2) and at least one compensating electrode (21.3) and at that measuring electrode (21.1) is galvanically separated from transparent electroconductive coating (3).

EFFECT: technical result consists in simplification of production of emergency glass system.
