  • Patent number: 11253869
    Abstract: The invention relates to a magneto-centrifugal flotation cell for ore concentration which reduces water consumption. A disadvantage of conventional flotation cells is the use of a large amount of water, some flotation cells requiring at least 60% water. The present invention uses ore pulp with increased density and viscosity, owing to the application of an axial magnetic field, wherein the Lorentz force, which is the force exerted by an electromagnetic field that receives a charged particle or an electrical current, can be used. The solution is a cell which, in addition to the forces that usually act on conventional flotation cells, uses external forces which, in principle, produce synergy in the separation of ore particles that have different gravitational and magnetic properties.

  • Patent number: 11181523
    Abstract: The invention is an ex vivo method for early detection of acute kidney injury in critical patients, which includes the measurements of fibroblast growth factor 23 (FGF23), klotho (KL) and erythropoietin (EPO) as biomarkers. These measurements are obtained from a venous blood sample or urine, and allow the determination of the following indicators: 1=([FGF23]p×[EPO]p); 2=([FGF23]p/[Klotho]p); 3=([EPO]p)/[Klotho]p); 4=([FGF23]p×[EPO]p)/[Klotho]p); where [X]p is defined as the plasma level of a specific molecule (X) which includes fibroblast growth factor 23 (FGF23), klotho (KL) or erythropoietin (EPO). If the value of the indicator 1, 2, 3, 4 or two or more thereof, is equal or higher than a cut-off point (10 U), the indicator and/or indicators allow the identification of patients with high risk of developing AKI, with a high sensitivity/specificity.

  • Patent number: 10996309
    Abstract: This patent concerns a compact and portable system for real-time detection and location of electromagnetic emissions in the spectrum used by mobile devices (cell phones and Wi-Fi/Bluetooth devices). The principle of detection and location is based on phased array technology, which enables the synthesis of a directional radiation beam that can be electrically controlled in terms of both its shape and direction. This technology is used primarily in military and astronomical applications. The device also includes localization and control algorithms. This device will allow for detecting and locating electromagnetic emissions by means of an antenna beam scan within a field of view of 80×80 degrees. Once the detection and location have been established, the results are overlaid to a visual image captured by a video camera.
