Publication number: 20240084144Abstract: Disclosed are reactive dyes and preparation methods thereof. The reactive dye may be prepared using heterocyclic primary amine as a diazo component, 4,4?-diamino-2,2?-stilbenedisulfonic acid, s-triazine, or ethylenediamine as a bridging group, and a dimonochlortriazine group as an active group. The color-changing compound is covalently bonded into the fiber chemical structure by nucleophilic substitution reaction between monochlorotriazine and the hydroxyl group in a textile structure, and the size of the conjugated system and the range of electron delocalization of the dye are changed by a reversible isomerization reaction of the hydroxyl group adjacent to the diazo group and the diazo group under different pH regulations. Moreover, the dye has a double color changing structure, which improves the capability of the dye combined with —H/—OH. The pH value range that can cause color changes in the dye is effectively expanded to include weak alkali, weak acid or even neutral conditions.Type: ApplicationFiled: August 7, 2023Publication date: March 14, 2024Applicant: NANTONG UNIVERSITYInventors: Min LI, Wujun MA, Jialiang ZHOU, Wenlin QU, Ting DING, Lifen MAO, Shiyu LI

Patent number: 11468417Abstract: Disclosed are various embodiments of a file service. In some embodiments, a plurality of files are stored. Each of the files includes a corresponding file object identifier and a corresponding storage object identifier. A user interface comprises a single view that shows the plurality of files. A file object identifier of a particular file is mapped to a storage object identifier for the particular file. The storage object identifier specifies a network address where a storage object of the particular file is stored. Access is provided to the particular file based at least in part on the storage object identifier.Type: GrantFiled: September 24, 2018Date of Patent: October 11, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Piragash Velummylum, Johanna S.

Patent number: 11403262Abstract: Disclosed are various embodiments for a local networked storage that is linked to a remote networked storage system. In one embodiment, among others, a computing device obtains a request to read a file stored in a remote networked storage system in association with a user account, in which the request is obtained from a client computing device through a local network. The computing device also determines that the file is stored in a local cache and receives the latest file signature associated with the file from the remote networked storage system. The computing device can determine that the latest file signature corresponds to a file signature of the file stored in the local cache and can determine that the file stored in the local cache corresponds to the latest version of the file. The file can be sent through the local network.Type: GrantFiled: January 5, 2021Date of Patent: August 2, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Piragash Velummylum, Johanna S. Olson, Korwin J. Smith, James H. Wood, Christopher G. Emery, Wenlin Ma

Patent number: 10931754Abstract: Architectures and techniques are described to provide personal remote storage space for electronic content items acquired (e.g., purchased) by a user of a client device. In some cases, as part of a transaction to acquire the electronic content item, an individual may receive an option that is selectable to indicate a preference to send electronic content items acquired by the individual to a personal remote storage space of the individual. When the option to store the electronic content item in the personal remote storage space is not selected by the individual, the electronic content item may be provided directly to a designated computing device of the individual.Type: GrantFiled: July 8, 2015Date of Patent: February 23, 2021Assignee: Amazon Technologies, Inc.Inventors: James H.
