Abstract: A laminated pane arrangement has a functional element based on liquid crystals, wherein the optical properties of the functional element and an electrical resistance heater of at least one flat electrode are controlled by two different AC voltages. In accordance with a first aspect, the functional element is contacted on two opposite sides by the AC voltages. The AC voltages differ in maximum amplitude, but have the same frequency. In accordance with a second aspect, the functional element is controlled by an AC voltage. At least one flat electrode is heated by an additional AC voltage of greater frequency. A fault in the control of the optical properties of the functional element is prevented by high-pass filters.

Abstract: An alarm pane assembly is presented. The alarm pane assembly includes a pane made of tempered glass, a transparent, electrically conductive coating that is arranged on a surface of the pane, a sensor unit, and an antenna. According to one aspect, the sensor unit includes a transmitting unit and an evaluation unit. During operation, the transmitting unit forwards a high-frequency voltage signal with a frequency f in a range of 0.1 GHz to 6 GHz to the antenna, the antenna emits electromagnetic radiation of the frequency f, and the evaluation unit measures the impedance matching of the transmitting unit to the antenna. According to another aspect, the antenna is electromagnetically coupled to the conductive coating, and the sensor unit outputs an alarm signal when the measured impedance matching deviates from a reference value.

Abstract: A pane arrangement directed to a heatable composite pane having a capacitive switching region, including a substrate and a cover pane is disclosed. At least one intermediate layer is arranged between the substrate and the cover pane. A carrier film having an electrically conductive layer is arranged between the substrate and the intermediate layer or between the cover pane and the first intermediate layer. The electrically conductive layer forms a capacitive switching region having a contact region, a supply line region, and a connection region. The supply line region electrically connects the contact region to the connection region that can be electrically connected to a sensor electronics system. A heating wire and at least two busbars are arranged between the substrate and the cover pane, wherein one end of the heating wire is electrically connected to one of the busbars. A capacitive sensor electronics system is electrically connected to the connection region via a first input and to the heating wire or to the busbars via a second input.

Abstract: A composite pane with a capacitive switching zone includes a substrate, a first intermediate layer areally bonded to the substrate, a second intermediate layer areally bonded to the first intermediate layer, and a cover pane areally bonded to the second intermediate layer. A carrier film with an electrically conductive layer is arranged between the first and second intermediate layers. A capacitive switching zone is electrically isolated from the electrically conductive layer by a coating-free separating line, the capacitive switching zone has a contact zone, a supply line zone, and a connection zone; the supply line zone electrically connects the contact zone to the connection zone, and the connection zone is electrically connectable to sensor electronics. The surface capacitance between the contact zone and the outside surface of the substrate is greater than the surface capacitance between the contact zone and the outside surface of the cover pane.
