  • Patent number: 12293511
    Abstract: A system for inspecting structural elements during their manufacturing capable of detecting anomalies in the automatic placement of composite materials through computer vision, comprising an image capture module that can be integrated into an ATL machine extracting data from the images, from which an artificial vision module obtains information on the anomalies detected with computer vision, information that a human-machine interface module automatically translates into a language understandable to humans. By avoiding the need to manually enter data for the inspection, human errors are avoided, and the information obtained for each inspection can be automatically saved for record storage. The system is designed to inspect large structural element compounds, such as aircraft wings.

  • Patent number: 12292262
    Abstract: A method for securing a geographical area encompassing a route. A map of the area is obtained. A weapon is associated with a firing modeling consisting of a probability model of hitting its target when shooting, as a function of the firing distance. Positions of potential shelters of threats on the map are determined by using a trained artificial intelligence device. The modeling is applied for each weapon and potential shelter while relating the shots to the route and summing all the probabilities of hitting its target on each portion of the route. The potential shelters most likely to constitute attack threats along the route are determined. A path is defined in order to address these potential shelters most likely to constitute attack threats.
