Publication number: 20230084796Abstract: The present invention provides a pressure-sensitive adhesive composition, including: an acrylic copolymer and a crosslinking agent. The acrylic copolymer is a reaction product of a mixture of the following monomers: a first alkyl (meth)acrylate, an alkyl group in the first alkyl (meth)acrylate having at least 6 carbon atoms; a second alkyl (meth)acrylate, an alkyl group in the second alkyl (meth)acrylate having 1 to 5 carbon atoms; and a vinyl carboxylic acid, the weight ratio of the vinyl carboxylic acid to the mixture being 4% to 5%. The crosslinking agent is an organometallic chelating agent. The weight ratio of the organometallic chelating agent to the mixture is 0.05% to 0.25%. The pressure-sensitive adhesive composition does not contain an effective amount of a tackifier. The present invention further provides a pressure-sensitive adhesive solution, a pressure-sensitive adhesive tape, and a method for preparing the same.Type: ApplicationFiled: January 18, 2021Publication date: March 16, 2023Inventors: Weina Wang, Lu Shen, Yunshu Zhang, Yu Che, Panpan Lin, Heng Liu, Xiaohai Sheng, Shupeng Wu, Xiangming Yang

Patent number: 10291696Abstract: A system is disclosed for managing large datasets. The system comprises a physical network. The physical network comprises a plurality of computing devices with a plurality of processors. The system further comprises a logical peer-to-peer (P2P) network with a plurality of nodes. The system further comprises a distributed file system for distributing data and jobs received by the system randomly across the plurality of nodes in the P2P network. The system duplicates the data to neighboring nodes of the plurality of nodes. The nodes monitor each other to reduce loss of data. The system further comprises a task scheduler. The task scheduler balances load across the plurality of nodes as tasks, derived from jobs, are distributed to various nodes. The task scheduler redistributes and forwards tasks to ensure the nodes processing the tasks are best suited to process those tasks.Type: GrantFiled: April 28, 2015Date of Patent: May 14, 2019Assignee: Arizona Board of Regents on Behalf of Arizona State UniversityInventors: Lei Ying, Weina Wang, Matthew Barnard
