Patent number: 10822528Abstract: A protective layer for use on a sensor during a manufacturing process avoids damage to the sensor and keeps the sensor surface clean during lens fabrication. The protective layer includes a non-cross-linked, water-soluble polymer layer and an anhydrous, cross-linkable, methacrylate-based formulation layer, temporarily applied to a surface of the sensor. The protective layer may be used to protect the sensor during a manufacturing process by applying the non-cross-linked, water-soluble polymer layer and the anhydrous, cross-linkable, methacrylate-based formulation layer consecutively onto the surface of the sensor to form the protective layer; affixing the sensor to a substrate; fabricating a device that includes the substrate; and subsequently removing the protective layer from the surface of the sensor.Type: GrantFiled: August 28, 2018Date of Patent: November 3, 2020Assignee: Verily Life Sciences LLCInventors: Parissa Heshmati, Jeffrey G. Linhardt, Brian Alvarez, Hojr Pisheh

Patent number: 9060847Abstract: A method for modifying the refractive index of an optical, hydrogel polymeric material. The method comprises irradiating predetermined regions of an optical, polymeric material with a laser to form refractive structures. To facilitate the formation of the refractive structures the optical, hydrogel polymeric material comprises a photosensitizer. The presence of the photosensitizer permits one to set a scan rate to a value that is at least fifty times greater than a scan rate without the photosensitizer in the material, yet provides similar refractive structures in terms of the observed change in refractive index. Alternatively, the photosensitizer in the polymeric material permits one to set an average laser power to a value that is at least two times less than an average laser power without the photosensitizer in the material, yet provide similar refractive structures.Type: GrantFiled: March 4, 2009Date of Patent: June 23, 2015Assignees: University of Rochester, Rochester Institute of TechnologyInventors: Thomas Smith, Wayne H.
