An automotive glazing system, comprising: at least one glass layer (2); a plurality of light emitters (10) injecting light into at least a portion of at least one edge of the glazing; a plurality of light detectors (20) measuring simultaneously the intensity of light emitted by each of said plurality of light emitters from at least a portion of at least one edge of the glazing; and at least one processing unit (15) communicably coupled to the automotive glazing, the plurality of light emitters and the plurality of light detectors to: scan periodically the intensity of light received by said plurality of light detectors; store the scanned data; compare new scans with historical data; estimate the presence of contaminants by a drop in intensity at some detectors without an increase at some detectors; and estimate the safety status of the glazing by identifying permanent damage by an increase in intensity at some detectors.
An automotive glazing system, comprising:
The automotive system glazing of any one of the preceding claims wherein said plurality of light emitters is comprised of at least two arrays of light emitters along two adjacent edges of the automotive glazing.
The automotive glazing system of any one of the preceding claims wherein said plurality of light detectors is comprised of two arrays of light detectors along two adjacent edges of the automotive glazing.
The automotive glazing system of any one of the preceding claims wherein said plurality of light emitters is selected from the group of:
The automotive glazing system of any one of the preceding claims wherein the light from said plurality of light emitters is emitted using a sequential scan mode.
The automotive glazing system of any one of the preceding claims wherein said plurality of light detectors is read and the light is measured in a sequential scan mode.
The automotive glazing system of any one of the preceding claims wherein said at least one processing unit is also configured to issue a suggestion to clean the automotive glazing.
The automotive glazing system of any one of the preceding claims wherein said at least one processing unit is also configured to issue a suggestion to repair the automotive glazing.
The automotive glazing system of any one of the preceding claims wherein said at least one processing unit is also configured to optionally trigger a washing mechanism.
The automotive glazing system of any one of the preceding claims wherein the light from said plurality of light emitters is white.
The automotive glazing system of any one of the preceding claims wherein said plurality of light emitters emits light in multiple wavelengths.
The automotive glazing system of any one of preceding claims wherein the glazing is a windshield.
A method for detecting permanent damage to the surface of an automotive glazing system comprising the following steps:
