Patent number: 11930117Abstract: Participants as requestors using a requesting network element request one or more tokenization processors to generate tokens that represent a sanitized version of data such that the resultant tokens are amenable to comparison across participants. As circumstances warrant, one or more such tokens can be submitted to the tokenization processor(s) to privately retrieve the original data. Role-based access control scope parameters and tokenization processor-specific tokenization processor secrets can be embedded into reversible tokens that remain invariant under updating of the tokenization processor secrets across tokenization processors.Type: GrantFiled: July 31, 2023Date of Patent: March 12, 2024Assignee: Springcoin, Inc.Inventors: David William Kravitz, Michael Young, Mollie Zechlin Halverson, Matthew Benjamin Smith

Publication number: 20240076769Abstract: Red rust staining of Al/Zn coated steel strip in “acid rain” or “polluted” environments can be minimised by forming the coating as an Al—Zn—Si—Mg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in “acid rain” or “polluted” environments and corrosion at cut edges in marine environments can be minimised in Al—Zn—Si—Mg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg2Si phase particles of a particular morphology in interdendritic channels.Type: ApplicationFiled: August 8, 2023Publication date: March 7, 2024Applicant: Bluescope Steel LimitedInventors: Ross McDowall SMITH, Qiyang LIU, Bryan Andrew SHEDDEN, Aaron Kiffer NEUFELD, Joe WILLIAMS, David James NOLAN, Wayne RENSHAW

Patent number: 9020358Abstract: An optical transmission network comprises a multi-wavelength source (7) shared between multiple sets of client side equipment for manipulating electrical signals. A first wavelength selective routing element (5) is connected to the multi-wavelength source (7). Each set of client-side equipment (1) comprises an optical modulator (3) connected to the first wavelength selective routing element (5) and an optical receiver (2). A second wavelength selective routing element (6) is connected to the optical receiver (2) and is operative to direct incoming signals from one or more remote locations to the optical receiver (2). The network provides a WDM architecture solution for networks whereby the cost of implementing and running client side equipment (1) is reduced by not having the WDM source (7) within the client side equipment (1).Type: GrantFiled: October 26, 2009Date of Patent: April 28, 2015Assignee: The Centre For Integrated Photonics LimitedInventor: David William Smith
