Patent number: 12213876Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.Type: GrantFiled: September 27, 2019Date of Patent: February 4, 2025Assignee: AMO Groningen B.V.Inventors: Carmen Canovas Vidal, Aixa Alarcon Heredia, Patricia Ann Piers, Hendrik A.

Patent number: 12172928Abstract: A method for manufacturing a concrete article is disclosed. The method comprises coating a mould or formwork with a release agent; spraying a mortar onto the mould or formwork, thereby forming a layer of mortar; casting concrete into the mould or formwork and onto the layer of mortar; and allowing the concrete to hydrate and harden in the mould or formwork, whereby a concrete article having a mortar skin layer is provided. The invention also provides concrete articles made by the described methods, and concrete structures which comprise the concrete articles. Concrete articles having the mortar skins can be made to have a relatively uniform outward appearance, even if the concrete cast behind the mortar skins may be different, in composition or appearance. Pigments or colorants and other expensive admixtures can be used in the mortar skin composition to greater visual effect, since the use of the mortar skin is less in overall volume compared to the concrete articles as a whole.Type: GrantFiled: June 12, 2018Date of Patent: December 24, 2024Assignee: GCP APPLIED TECHNOLOGIES INC.Inventors: Dany Vincent, Klaus-Alexander Rieder, Stephen P.
