Patent Issued for Integrated system for real-time anti-fouling and biofouling monitoring (USPTO 11679423).

The anti-biofouling system according to claim 1, wherein the optical sensor is configured to sense UV radiation reflected by the UV radiation exit window, and wherein the anti-biofouling system is configured to increase an intensity of said UV radiation when the optical sensor senses a reduction in the reflected UV radiation. The anti-biofouling system according to claim 1, wherein the light source is configured to provide at least part of said UV radiation within a total internal reflection critical angle with said radiation exit window, wherein the optical sensor is configured to sense scattered UV radiation from the downstream window side of the radiation exit window, and wherein the anti-biofouling system is configured to increase an intensity of said UV radiation when the optical sensor senses an increase in the scattered UV radiation. An anti-biofouling system comprising: an UV-emitting element, a light source, and an optical sensor, wherein the UV-emitting element comprises: a UV radiation exit window, wherein the UV-emitting element at least partly encloses the light source configured to provide UV radiation, wherein the UV radiation exit window is configured to transmit at least part of the UV radiation of the light source, wherein the UV radiation exit window comprises an upstream window side and a downstream window side, wherein the UV-emitting element also at least partly encloses the optical sensor configured to sense radiation emanating from the downstream window side and generated by the light source, and configured to provide a corresponding optical sensor signal, wherein the anti-biofouling system is further configured to provide said UV radiation in dependence of said optical sensor signal.
