Abstract: A blanking device generates a blanking signal to obscure signals on a license plate in response to a monitoring flash directed at the license plate. The device includes at least two sensors spaced apart to enable the device to differentiate between a monitoring flash from a device attempting to take an image of the license plate and other spurious signals.
Abstract: A license plate assembly includes a frame receiving a conventional license plate and at least one blanking flash generator arranged to generate a blanking flash at the license plate in response to a monitoring flash from an external monitoring device. The monitoring device is designed to take an image of the license plate and the blanking flash is obscuring the license plate to prevent or interfere with the taking of the image.
