Patent number: 11440838Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition. In certain embodiments, the device includes a counter electrode having an anodically coloring electrochromic material in combination with an additive.Type: GrantFiled: April 27, 2020Date of Patent: September 13, 2022Assignee: View, Inc.Inventors: Anshu A. Pradhan, Robert T. Rozbicki, Dane Gillaspie, Sridhar K. Kailasam

Patent number: 11409142Abstract: Metallic and dielectric domains in phase change materials (PCM) provide spatially localized changes in the local dielectric environment, enabling launching, reflection, and transmission of hyperbolic polaritons (HPs) at the PCM domain boundaries, and tuning the wavelength of HPs propagating in hyperbolic materials over these domains, providing a methodology for realizing planar, sub-diffractive refractive optics. This approach offers reconfigurable control of in-plane HP propagation to provide design optical functionality because the phase change material can be manipulated by changing the local structure, for example, to manipulate polaritons in the adjacent hyperbolic material, thus tuning the wave propagation properties of the polaritons in the hyperbolic material.Type: GrantFiled: March 7, 2019Date of Patent: August 9, 2022Assignees: Vanderbilt University, University of Georgia Research Foundation, Inc.Inventors: Joshua D.

Patent number: 11391968Abstract: A spectacle lens including a prism prescription that has an eyeball-side optical surface. When one side is the same side as a prism base direction (nose side) and the other side is an opposite side of the prism base direction with a direction orthogonal to the prism base direction passing through a prism measurement reference point as a boundary, a minimum value of a curvature of the eyeball-side optical surface is on the same side as the prism base direction (nose side). Since a mean curvature becomes smaller in the prism base direction than a mean curvature of the prism measurement reference point and becomes larger in the opposite direction than the mean curvature of the prism measurement reference point across the prism measurement reference point, deviation in line of sight between right and left eyes is resolved.Type: GrantFiled: June 6, 2017Date of Patent: July 19, 2022Assignee: HOYA LENS THAILAND LTD.Inventors: Takashi Hatanaka, Tomohiro Odaira
