Embodiment Construction

[0031] A glazing consisting of a 0.76 mm dark gray interlayer laminated between two outer clear glass layers of 2.1 mm thickness was used for initial testing.

[0032] The tests were performed using a solid-state pulsed laser. Such lasers are used to decoat glass, such as disclosed in US2003 / 0075531, and typically operate at 532nm with nanosecond pulse times. Adjust spot size, laser power, and pulse frequency according to the nature of the sample being processed.

[0033] The sample is processed by scanning an area of ​​the glass window with a laser beam. The laminated glazing can be held in a fixed position and the laser moved, the laser held in a fixed position and the glazing moved, or both, to achieve this scanning. The key point is to set the laser to move relative to the laminated glass window in a carefully controlled manner. Make several parallel movements of the laser relative to the laminated glazing. This results in the formation of corresponding parallel tracks...

Abstract

A laser can be used to modify a glazing (100, 300) so as to improve its suitability for use with a signal-receiving device (350) or a signal-transmitting device (350). This is done by using the laser to provide a region of reduced opacity (110, 202, 340) to the signal within the glazing. Preferably, the laser is be used to reduce the opacity of a selected region (340) of a tinted interlayer in situ. The glazing may be for a vehicle, especially an automotive vehicle.

Description

technical field [0001] The present invention relates to a glazing, in particular to a glazing suitable for use with signal detection or signal transmission devices. Background technique [0002] Signal detection devices and signal transmission devices are known and are currently increasingly used in combination with glazing. This is especially true for glazing used in advanced high-value products, such as those used in automobiles. These devices are mounted on glass windows inside vehicles and are used to send or receive signals through the glass windows. [0003] The signal detection means may be, for example, for detecting events or conditions occurring outside the vehicle. The signal may be, for example, used to assess or detect changes in weather conditions (e.g., temperature, pressure, sunlight, rain, fog, smog, mist, snow, ice), noise level, vibration level, sound level, motion, etc. . Commonly used sensors in cars include rain sensors (to activate windshield wiper...
