Publication number: 20240123120Abstract: A corneal implant with adhesion-increase treatment is associated with a method for increasing the adhesion of the artificial corneal implant by an epoxy-amine ring-opening reaction of the polyamino high-molecular polymer and glycidyl methacrylate to obtain a methacrylate modified polyamino polymer. The method improves the adhesion and biocompatibility of the artificial corneal endothelial sheet by photo-initiated free radical polymerization reaction, and has a high oxygen permeability and a high adhesion. It can be used for treating patients with corneal endothelial decompensation, playing a barrier role to block aqueous humor, eliminating corneal edema, and reducing the risk of corneal graft detachment after surgery.Type: ApplicationFiled: July 13, 2022Publication date: April 18, 2024Inventors: Weiyun SHI, Ting WANG, Qingjun ZHOU, Xiaoyu ZHANG, Hongwei WANG

Publication number: 20230102802Abstract: The present technology provides systems, methods, and devices that can update aspects of a map as an autonomous vehicle navigates a route, and therefore avoids the need for dispatching a special purpose mapping vehicle for these updates. As the autonomous vehicle navigates the route, data captured by at least one sensor of an autonomous vehicle can indicate an inconsistency between pre-mapped from a high-resolution sensor system describing a location on a map, and current data describing a new feature of the location. The current data can be clustered together based on a threshold spatial closeness, where the clustering describes the new feature, and semantic labels of the pre-mapped data from the high-resolution sensor system can be updated based on the new feature described by the clustered current data.Type: ApplicationFiled: December 6, 2022Publication date: March 30, 2023Inventors: Juan Fasola, Harman Kumar, Yu-Cheng Lin, Xiaoyu Zhou
