A switchable laminated glazing with improved bus bar that solves the problem of inhomogeneities and reduce the cost of its fabrication by providing a laminated glazing that comprise a switchable layer (14) that has an active material sandwiched between two conductive coated plastic layers (8), at least two bus bars (20) in electrical contact with the respective conductive coated plastic layer (8), and at least two pliable conductive media (12), each of them between the respective coated plastic layer (8) and bus bar (20). The area covered by pliable conductive medias (12) is substantially less than the area covered by bus bars (20).

A system for detecting damage to a glass surface particularly vehicle glazing panels such as vehicle windscreens. The system uses a sensor unit disposed proximate the surface and a processor in communication with the sensor unit. The processor is configured to analyse data received from the sensor unit in order to determine the integrity of the surface and a communication unit is configured to output a signal in response to the processor determining that the surface has been damaged. For vehicle glass the system is preferably integrated into the vehicle management and control systems such that the system is active when the vehicle is active or moving. The management and or control system may monitor for instances or situations when changes, such as above threshold changes, occur in order to produce an output warning signal.
