Publication number: 20230160851Abstract: In one general aspect, an electrophoretic measurement method is disclosed that includes providing a vessel that holds a dispersant, providing a first electrode immersed in the dispersant, and providing a second electrode immersed in the dispersant. A sample is placed at a location within the dispersant between the first and second electrodes with the sample being separated from the electrodes, an alternating electric field is applied across the electrodes, and the sample is illuminated with temporally coherent light. A frequency shift is detected in light from the step of illuminating that has interacted with the sample during the step of applying an alternating electric field, and a property of the sample is derived based on results of the step of detecting.Type: ApplicationFiled: May 11, 2020Publication date: May 25, 2023Applicant: Malvern Panalytical LimitedInventors: Jason Cecil William Corbett, Malcolm Connah, Kevin Mattison

Patent number: 10776888Abstract: A datastore that includes property listings (e.g., for rental properties) may be accessed by a computing resource configured to execute a thumb printing algorithm to generate summary data values (e.g., thumbprint values, hash values) of digital data included one or more images of a property listing. The summary data values along with listing attributes (e.g., address, zip code, geolocation, brand, number of bedrooms/bathrooms/sleeps, amenities) of the property listing may be compared with summary data values and listing attributes of other property listings to determine if the summary data values of one or more images match and if one or more listing attributes match. A threshold number of image matches and listing attribute matches may indicate that the property listings are duplicate property listings, which may be merged, removed or replaced with links/pointers by the computer resource to increase data storage space and/or reduce data search latency times of the datastore.Type: GrantFiled: December 22, 2017Date of Patent: September 15, 2020Assignee: HomeAway.com, Inc.Inventors: Ronald William Corbett, Bryon Kristen Jacob, David Petty

Patent number: 10592476Abstract: Various embodiments relate generally to a system, a device and a method provide for enabling clients to expose secured files via virtual hosts. A request may be received from a user device such that the request is associated with a content item. The request may include a file path and a content identifier. A host name of the file path may be determined from the request. Data representing a physical location of the content item within a file storage system may then be determined based on a mapped bucket associated with the host name and the content identifier. The content item may be retrieved based on the data representing the physical location within the file storage system and provided to the user device responsive to the request.Type: GrantFiled: October 19, 2015Date of Patent: March 17, 2020Assignee: HOMEAWAY.COM, INC.Inventors: Bryon Kristen Jacob, Ronald William Corbett

Patent number: 10566296Abstract: In the invention described, magnetic field characteristics of randomly placed magnetized particles are exploited by using the magnetic field fluctuations produced by the particles as measured by a sensor. The magnetized particles generate a complex magnetic field near the surface of an integrated circuit chip on a bank card or identification card that can be used as a “fingerprint.” The positioning and orientation of the magnetized particles is an uncontrolled process, and thus the interaction between the sensor and the particles is complex. The randomness of the magnetic field magnitude and direction near the surface of the material containing the magnetic particles can be used to obtain a unique identifier for an item such as an integrated circuit chip on a bank card or identification card carrying the PUF.Type: GrantFiled: November 10, 2017Date of Patent: February 18, 2020Assignee: Lexmark International, Inc.Inventors: Roger Steven Cannon, William Corbett, Gary A. Denton, James Paul Drummond, Kelly Ann Killeen, Carl E. Sullivan
