Abstract: One of the problems is the reduction in interior areas and surfaces where various types of devices can be mounted. To address this issue more and more of these devices are being integrated with the glazing. Laminated glazing is especially suitable for thin devices. Today, laminated glazing is produced with heating elements, antennas, lighting, touch sensors, RFID, electronic blinds and other types of devices integrated as a permanent part of the glazing. The invention comprises an automotive laminate with a thin integrated electroacoustic transducer integrated in the glazing.

Abstract: Functional layers do not have a good performance at lower temperatures. This limitation is overcoming by combining the functional layers with a resistive heating circuit. The heating circuit uses minimal power to maintain the glazing at or above the temperature required for acceptable operation.
