Patent number: 11201857Abstract: A domain transcendent file cryptology network includes a first data cryptology node in a first data domain having a first security protocol. A hardware processor of the first data cryptology node executes a first instantiation of a software code to receive a request to transfer a data file from the first data domain to a second data domain having a second, different, security protocol, obtain one or more characteristics of the data file, and generate an authentication tag for the data file based on the characteristic(s). The first instantiation of the software code also encrypts the data file and transmits the encrypted data file, the authentication tag, and a decryption key to a second data cryptology node in the second data domain. The decryption key and the authentication tag enable decryption of the encrypted data file by a second instantiation of the software code on the second data cryptology node.Type: GrantFiled: December 9, 2019Date of Patent: December 14, 2021Assignee: Disney Enterprises, Inc.Inventors: Thomas C.

Patent number: 11198741Abstract: The object of the present invention relates to the new and surprising use of sulfated hyaluronic acid (HAS) as regulator agent of the cytokine activity (pro- and anti-inflammatory) and consequently the use of HAS for the preparation of a new medicine for topic use in the prevention and treatment of pathologies associated with the activation and/or deficiency of cytokines of a pro- and anti-inflammatory nature. The Applicant has in fact discovered the exclusive capacity of HAS in modulating the activity of these particular proteins, it has studied the action mechanism and demonstrated the substantial difference between the different sulfated types known in the state of the art, but above all it has demonstrated an unexpectedly high activity of HAS vs different types and strains of Herpes virus, Cytomegalovirus and the virus of vesicular stomatitis. Finally, a further object of the present invention is the use of HAS as a skin absorption promoter of drugs of an anti-inflammatory nature.Type: GrantFiled: August 26, 2019Date of Patent: December 14, 2021Assignee: FIDIA FARMACEUTICI S.p.A.Inventors: Matteo D'Este, Giovanni Gennari

Patent number: 10080568Abstract: Devices are described relating to the retaining of surgical tools within the chuck of a reciprocating surgical instrument, such as a reciprocating saw. A securing chuck is disclosed for securing a surgical tool to a reciprocating surgical instrument that comprises a shaft and a securing member. The shaft defines an axis and has a cylindrical bore extending along the axis. The bore is shaped to receive a substantially rounded tool shank. A pair of transverse slots extends into the shaft along a plane passing through the axis for receiving a substantially flattened tool shank. The transverse slots intersect with the cylindrical bore. The securing member is carried by the shaft and is radially movable relative to the bore both inwardly and outwardly to secure the surgical tool in the chuck.Type: GrantFiled: May 9, 2016Date of Patent: September 25, 2018Assignee: Medtronic Xomed, Inc.Inventor: Larry D.

Patent number: 9409173Abstract: Provided herein are devices and methods for generating microfluidic gradients, including an array of unique microfluidic gradients within an array of microchannels. Fluids within conduits are mixed in an intersection region to generate a mixed flow stream in a source reservoir channel that provides a gradient that varies with axial distance from the intersection region. Microchannels having an inlet connected to the source reservoir channel are configured to provide a microfluidic gradient in the microchannel. An outlet end of the microchannel is connected to a sink reservoir channel. By varying the ratio of fluid flow rates from the fluid conduits, the microchannel gradients are tuned. In this manner, a large number of unique gradients or array of microfluidic gradients is provided, wherein the gradient can be any number of physical or chemical parameters, including concentrations and physical fluid properties.Type: GrantFiled: November 27, 2013Date of Patent: August 9, 2016Assignee: The Arizona Board of Regents on Behalf of The University of ArizonaInventors: Matthew D Estes, Cedric M Hurth, Frederic Zenhausern
