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

FIELD: signaling devices.

SUBSTANCE: present invention relates to window system (10, 10 ') with emergency signaling. Window glass system includes at least first plate (1), which consists of prestressed glass, with surface (I) of outer side and surface (II) of inner side, at least one transparent electrically conductive coating (3) which is arranged on the surface (II) of the inner side of first plate (1), and sensor unit (20) with inductive sensor (21) which is inductively coupled to the transparent electrically conductive coating (3), wherein sensor unit (20) in response to mismatch of measurement signal from inductive sensor (21) with control value generates an alarm signal, wherein inductive sensor (21) comprises exactly one measuring coil (21.1), preferably measuring coil (21.1) with ferrite core (21.2).

EFFECT: simplified system.
