Patent number: 11251940Abstract: An approach is provided for deterring a tampering of content. Content is signed by using an asymmetric key cryptography. The signed content is stored in a distributed ledger which is accessible to a plurality of subscribers of the distributed ledger. The signing of the content using the asymmetric key cryptography together with the storing of the signed content in the distributed ledger provide a non-repudiable identification of an owner of the content and a non-repudiable proof of an ownership of the content.Type: GrantFiled: March 22, 2019Date of Patent: February 15, 2022Assignee: Kyndryl, Inc.Inventors: Michael C. Davis, Robert S. Milligan, Gordan G. Greenlee, Christopher L. Molloy, Steven A. Waite

Patent number: 11176209Abstract: A computer-implemented method, system and computer program product for improving query searches. After receiving a query from a user to conduct a content search, the query is analyzed for its semantic meaning and a categorized group of query tags and content tags in the central repository that is most semantically similar in meaning to the meaning of the query is identified. Furthermore, the content tags and query tags in the user's repository are analyzed to determine the interests of the user. The query may then be augmented to include one or more other terms of interest from the identified categorized group of query tags and content tags in the central repository that match the determined interests of the user within a threshold degree of relatedness, where these other terms of interest correspond to the content tags and query tags of the identified categorized group based on their assigned weight.Type: GrantFiled: August 6, 2019Date of Patent: November 16, 2021Assignee: International Business Machines CorporationInventors: Michael C. Davis, Robert S. Milligan, Gordan G. Greenlee, Jason LaScola, Christopher L. Molloy, Steven A. Waite

Patent number: 10859650Abstract: Methods are described for quantifying an amount of natural rubber in a plant from a sample of the plant by obtaining a NMR spectrum and analyzing the signal peaks for the natural rubber in the plant sample and a standard component tested in combination with the plant sample. The NMR testing is conducted on a liquid state sample of a solution containing dissolved plant sample and standard component. A pre-determined and known amount of standard component is present in the liquid state sample and provides a reference for calculating an estimated amount of natural rubber in the plant sample. The estimated amount of natural rubber in the sample can be used to quantify the amount of extractable rubber in the sampled plant.Type: GrantFiled: June 29, 2017Date of Patent: December 8, 2020Assignee: Bridgestone CorporationInventors: Michael C.

Patent number: 10578567Abstract: Methods are described for quantifying an amount of natural rubber in a plant from a sample of the plant by obtaining a T1 spin-lattice relaxation rate or T2 spin-spin relaxation rate from a NMR apparatus, such as a low-field NMR apparatus operating at a magnetic field strength of 2 T or less. The NMR relaxation rates obtained from the plant sample are compared to reference relaxation data or plots. The plots can represent the weight percent polyisoprene versus T1 spin-lattice relaxation rate or T2 spin-spin relaxation rate. The reference relaxation data or plots are generated from testing the same type of plant as the sample.Type: GrantFiled: December 29, 2015Date of Patent: March 3, 2020Assignee: Bridgestone CorporationInventors: Michael C. Davis, Yingyi Huang

Patent number: 10042014Abstract: An apparatus and method for testing and analyzing the molecular structure of a sample material in an NMR device are described. A sample is held in a pre-determined stretched state in an apparatus that includes the sample arranged between two body components that are secured together with one or more retaining members that fit around the bodies or portions thereof. The apparatus is inserted into an NMR device to obtain NMR spectrums for analyzing the molecular structure of the samples, for instance, identifying strain-induced crystallinity and quantifying the same at pre-determined stretch ratios of a sample material.Type: GrantFiled: April 19, 2016Date of Patent: August 7, 2018Assignees: Bridgestone Corporation, The University of AkronInventors: Toshikazu Miyoshi, Michael C.

Patent number: 9732808Abstract: A one-way clutch, including: an inner race including a first outer circumference with a first plurality of ramps and at least one wedge plate including: a first inner circumference with a second plurality of ramps; a second outer circumference; and a first plurality of slots: passing through material forming the at least one wedge plate in an axial direction; including respective first ends open to the second outer circumference; and including respective second ends radially outward of the first inner circumference and enclosed by the at least one wedge plate. The one-way clutch includes an outer race including a second inner circumference. The outer race is able to rotate with respect to the inner race in a first circumferential direction. Rotation of the outer race in a second circumferential direction, opposite the first circumferential direction, causes the rotation of the outer race to lock to rotation of the inner race.Type: GrantFiled: July 9, 2013Date of Patent: August 15, 2017Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 9046140Abstract: A one-way clutch, including an inner race and a wedge component with first and second tapered outer partially circumferential surfaces. The clutch includes first and second outer races including respective tapered inner partially circumferential surfaces. For rotation of the outer races, with respect to the inner race, in a first direction, the outer races are axially aligned and separated by a space in an axial direction, the first and second tapered outer partially circumferential surfaces and the respective tapered inner partially circumferential surfaces are at least partially aligned in radial and axial directions and are free of contact. For rotation of the outer races, with respect to the inner race, in a second direction, opposite the first direction, the first and second tapered outer partially circumferential surfaces contact the respective tapered inner partially circumferential surfaces and the first and second outer races are non-rotatably connected to the inner race.Type: GrantFiled: October 9, 2013Date of Patent: June 2, 2015Assignee: Schaeffler Technologies AG & Co.

Patent number: 9016451Abstract: A one-way clutch, including: a plurality of first ramps with respective first face surfaces orthogonal to an axis of rotation or forming a first acute angle with the first line. The clutch includes at least one wedge plate including a smooth second outer circumference and a first inner circumference with a plurality of second ramps with respective second face surfaces orthogonal to the axis of rotation in the radial direction or forming a second acute angle with the second line. The clutch includes an outer race including a second inner circumference. The outer race is rotatable with respect to the inner race in a circumferential direction. For relative rotation of the outer race in the direction, at least one, but not all, first face surfaces is in contact with second face surface. Rotation of the outer race in an opposite circumferential direction locks the inner and outer races.Type: GrantFiled: July 9, 2013Date of Patent: April 28, 2015Assignee: Schaeffler Technologies AG & Co.
