  • Patent number: 12116442
    Abstract: The invention provides a contact lens manufacturing method comprising a process for removing unprocessed molded silicone hydrogel contact lenses from mold halves in a relatively efficient and consistent manner. The method of the invention involves using a silicone fluid (or so-called silicone oil) as non-reactive diluent in SiHy lens formulation for making SiHy contact lenses. Resultant SiHy contact lenses cast-molded from such a SiHy lens formulation can have a significantly reduced adhesion force with the molding surfaces of a lens mold and consequently a higher efficiency and consistency in removing unprocessed molded SiHy contact lenses from mold halves can be achieved. This method of the invention can be easily implemented in a production environment for enhancing the production yield.

  • Patent number: 12077632
    Abstract: The present disclosure discloses a waterborne epoxy resin for an anti-corrosion coating, and a preparation method and use thereof. In the preparation method, a strongly-hydrophilic polyethylene glycol (PEG) branch is introduced into a molecular chain of epoxy resin to realize the self-emulsification function of epoxy resin. Moreover, due to the short molecular chain, a solid content can reach up to 66.7% under the action of PEG. In addition, the waterborne emulsion can be prepared without adding any additional alcohol-soluble solvents and other high-boiling-point organic solvents, and a production process and a product use process both are very environmentally friendly. The waterborne epoxy resin can be mixed with a waterborne ammonia curing agent to form a film for corrosion protection.

  • Publication number: 20240282118
    Abstract: In various examples, one or more object detectors may regress bounding polygons for detected objects in systems (e.g., autonomous or semi-autonomous driving systems and applications) that provide object awareness, object identification, object avoidance, and/or object localization. The object detector may determine regression data representing a regressed polygon associated with a given shape of a detected object represented by classification data determined from a scene. The object detector may determine regression data for different regressed angles between different pairs of successive vertices of the regressed polygon and regressed lengths of vectors from a regressed geometric center of the regressed polygon to vertices of the regressed polygon. The object detector may generate, based at least in part on the regression data, a bounding shape for a detected object in the scene. In some embodiments, the object detector may be trained by deforming a regressed polygon to match a ground truth polygon.
