  • Patent number: 10816823
    Abstract: The invention relates to a contact lens for use in the treatment of ocular inflammatory pathologies. The contact lens comprises a soft porous material coupled, in certain embodiments, with detoxifying agents. Said material and/or agents contact and neutralize inflammatory mediators present in the tear fluid of ocular pathologies patients. The nature and architecture of the soft porous material allows a greater contact area between the material itself and/or detoxifying agents with inflammatory mediators, in view of the reversible compression of the soft material that allows greater lachrymal fluid turnover and fluid exchange within the contact lens upon e.g. blinking.

  • Patent number: 10702830
    Abstract: A thermal water purification system and a related method including distilling units consecutively flowed through by raw feed liquid, each having a boiling liquid section and a vapor section, and including a heat exchanger cavity adapted to transfer thermal energy to the raw feed liquid before entering the boiling liquid section of a first distilling unit. Heat exchanger tubes in fluidic communication with the heat exchanger cavity extend through the boiling liquid section of the first distilling unit to transfer thermal energy from a medium in the tubes to cause the raw feed liquid to boil. Preheating tubes extend through the vapor section of each distilling unit to heat the raw feed liquid before entering the boiling sections using thermal energy from vapor condensing against external surfaces of the preheating tubes, which produces the distillate liquid that flows through a discharge port and a conduit supplying a storage tank.

  • Patent number: 10593125
    Abstract: We disclose a method for synthesizing by computer an artwork where 2D and 3D contents are integrated within a same composition. Such an artwork creates plausible effects for the viewers by showing a different relationship between 2D and 3D at each viewing angle. Methods are proposed for ensuring the continuity between the 2D and the 3D parts in terms of mesh geometry and reflected colors. The user selects from a given scene a region of interest (ROI) to be reproduced in 3D. A flat rendering grid is created that matches the topology and tesselation of the ROI. The ROI is attached to the rendering grid. To enhance the continuity between the 2D and the 3D parts of a scene object, the 2D part of the object can be represented as bas-relief. Designers can create 2D-3D sculpture paintings for decoration, exhibitions, and homes.
