International Classification:

H01Q 132

US Classification:

343713

Abstract:

The present invention provides a transparent antenna including a transparent dielectric substrate, an electroconductive antenna element positioned along a major surface of the substrate, an electroconductive patch capacitively or directly connected to the antenna element, and a connector secured to the patch to permit transfer of signals generated by the antenna element to an electromagnetic energy transmitting and/or receiving device. The patch, is configured to have a visibility coefficient (i. e. a ratio of the non-opaque area to the total area) between 0 and 1. In one particular embodiment of the invention, the antenna element includes one or more transparent, electroconductive coatings positioned between first and second glass plies of a windshield for a motor vehicle and the electroconductive patch is applied to an exposed major surface of the windshield such that it overlays at least a portion of the antenna element and is capacitively coupled to the antenna element. The patch is may be formed from an opaque electroconductive ceramic IR, UV, thermoplastic or thermoset paint.

International Classification:

B23K 31/02
B60L 1/02

US Classification:

228121, 2281221, 219203

Abstract:

The invention relates to using the heat generated during thermal treatment of one or more glass sheets to melt solder. In one nonlimiting embodiment, a lead providing external access to an electrical conductive arrangement, e. g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e. g. a lead soldered to each of the bus bars during thermal processing of the sheets, e. g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks. Soldering the leads during the annealing or laminating process eliminated possible thermal damage to the sheet by having the sheet heated during the soldering operation instead of only a small surface portion of the sheet at and eliminates the cost of a separated soldering operation.

B60L 1/02

US Classification:

219203, 219522, 219543, 428630, 428632

Abstract:

An electrically heatable transparency has at least one substrate, a first bus bar spaced from a second bus bar, and a conductive coating formed over at least a portion of the substrate. The first and second bus bars are in electrical contact with the coating. At least one of the bus bars has an end region in electrical contact with the coating. The end region is tapered such that the coating is of substantially uniform thickness on the end region.

Abstract:

A low temperature solder including indium in the range of 62-65 weight percent and tin in the range of 31-33 weight percent uses the heat generated during thermal treatment of one or more glass sheets to melt the solder. In one non-limiting embodiment, a lead providing external access to an electrical conductive arrangement, e. g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e. g. a lead soldered to each of the bus bars during thermal processing of the sheets, e. g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks.

Inventors:

John Winter - Pittsburgh PA, US

International Classification:

B60L 1/02

US Classification:

219203000

Abstract:

An electrically conductive, minuscule size particle containing liquid solution or particle free liquid solution is applied, e.g. by ink jet printing technique to a surface, e.g. the surface of a glass sheet and drying the applied liquid in any convenient manner, e.g. during the heat treatment, or shaping, of the sheet to dry the liquid which results in the metal solute of the liquid solution to dry and adhere together to provide a solid electrically conductive strip on the glass surface. In one non-limiting embodiments of the invention, the solid conductive strips are a plurality of spaced conductive strips having a width no greater than 0.20 millimeters in the vision area of an automotive windshield.
