The invention relates to a method for regulating, by means of a computer, a resistive element arranged to deice and/or demist a support, the method comprising:

a) a loop for monitoring the temperature T and the moisture level H at the support;

b) a deicing and/or demisting sequence which, as long as the temperature T and the moisture level H monitored by the monitoring loop a) are indicative of an absence of frost or mist on the support, keeps the resistive element inactive and, in the contrary case, demands, in a step b2), the circulation of a current I in the resistive element so that the latter dissipates a thermal power P.sub.th, adjusted according to the temperature T and the moisture level H, and providing deicing or demisting of the support over a predetermined period D.sub.p.

One general aspect includes a system having one or more heat pads installed at a vehicle, the one or more heat pads configured to provide infrared energy transmissions to a vehicle component to defrost, defog, or both defrost and defog a surface of the vehicle component. The system may also carry out the following steps: (a) determining that ice or fog or both ice and fog has accumulated on the surface of the vehicle component; and (b) based on the determination made in step (a), activating the one or more heat pads to defrost, defog, or both defrost and defog a surface of the vehicle component.

A glass plate module (10) according to the present invention includes a glass plate (1), a conductive layer (2) laminated on the glass plate (1), at least one connection terminal (3) fixed to the conductive layer (2), and made of a conductive material, and an adhesive material (4) for fixing the connection terminal (3) to the conductive layer (2). The connection terminal (3) includes a connector connection portion (37) that is to be electrically connected to an external connector, one or more installation portions (31, 32) that are installed on the conductive layer (2), and electrically connect the connector connection portion (37) and the conductive layer (2), at least one easily deformable portion (34) that is provided between one of the installation portions (31, 32) and the connector connection portion (37), and is deformable due to an external force, and at least one protrusion (35) provided anywhere between the connector connection portion (37) and the easily deformable portion (34), and protruding in a direction in which the conductive layer (2) extends and that intersects a direction in which the connector connection portion (37) extends.

A system such as a vehicle may have windows with one or more conductive layers. The conductive layers may form part of an infrared-light-blocking layer or other layer. The infrared-light-blocking layer or other layer may be formed as a coating on a transparent structural window layer such as an outer or inner glass layer in a laminated window or may be embedded in a polymer layer between the outer and inner layers. Segmented terminals and elongated terminals that may extend past two or more segmented terminals may be coupled to the edges of the conductive layers. Using these terminals, control circuitry can apply localized ohmic heating currents and can make resistance measurements on the conductive layers to detect cracks.

The invention proposes a wiper blade (10) of a motor vehicle, comprising a heating electrical circuit (30) comprising at least one heating resistive element, which is connected to terminals (36) for supplying electric current, and a component for regulating the electric power supply current, which is a resettable fuse with a positive temperature coefficient (50), known as a PTC fuse. The PTC fuse (50) is, for example, a surface-mounted component, known as a CMS component, which is electrically connected to two belonging electrical connecting areas (44, 46).

The present disclosure relates to a vehicle glazing, comprising: a first glass substrate having surfaces S1 and S2 wherein S1 faces a vehicle exterior; a second glass substrate having surfaces S3 and S4 wherein S4 faces a vehicle interior; at least one polymer interlayer between the first glass substrate and the second glass substrate; and a coating on at least one surface of at least one of the first and second glass substrates, wherein at least one opening is formed in the coating, and the opening is filled with an electrically conductive material, wherein the electrically conductive material is attached to at least one electrical connector.

Laminated glazings with embedded wire circuits, have many uses. But, due to the higher cost of manufacture, they are not widely used. This invention provides a process to reduce the cost of production for embedded wire laminated glazing. Rather than embedding the wire one interlayer at a time, several circuits are produced on the same sheet, cut out and then inserted into the interlayer of each separate laminate during assembly, reducing the direct labor and capital investment required.

A composite pane is described. The composite pane has a first pane, at least one intermediate layer, a second pane, a transparent, electrically conductive first coating between the intermediate layer and the first pane and/or between the intermediate layer and the second pane, a first busbar and a second busbar, and a transparent, electrically conductive second coating.

The invention concerns a conductive pattern sheet for use in a glazing, comprising a substrate, a conductive pattern arranged on the substrate, wherein the conductive pattern comprises first and second busbars arranged at opposing edges of the conductive pattern for connecting a power supply thereto, a plurality of conductive lines each conductive line arranged between the first and second busbars, wherein at least a portion of the plurality of conductive lines is configured to have a transition region wherein a change from a first resistance per unit length (R1) at a first end of the transition region to a second resistance per unit length (R2) at a second end of the transition region occurs over a predetermined length (L) of the transition region wherein a rate of change of resistance per unit length (R1-R2)/L is from 1 to 16,000 ohms per centimetre squared and the substrate is a polymer sheet.

A system such as a vehicle may have windows with one or more conductive layers. The conductive layers may form part of an infrared-light-blocking layer or other layer. The infrared-light-blocking layer or other layer may be formed as a coating on a transparent structural window layer such as an outer or inner glass layer in a laminated window or may be embedded in a polymer layer between the outer and inner layers. Segmented terminals and elongated terminals that may extend past two or more segmented terminals may be coupled to the edges of the conductive layers. Using these terminals, control circuitry can apply localized ohmic heating currents and can make resistance measurements on the conductive layers to detect cracks.
