Patent number: 10725131Abstract: A topologically-protected traveling-wave amplifier includes resonators arranged in a two-dimensional array defining a periphery including a first edge. An output line is coupled to an output resonator disposed along the first edge spaced from an input resonator coupled to an output line. A synthetic gauge field generator associated with the resonators provides a topologically-protected edge state corresponding to propagation along the periphery in a propagation direction from the input resonator along the first edge to the output resonator. A parametric driving element creates pairs of photons in the edge state and amplifies a signal propagating along the first edge in the propagation direction. A signal incident from the input line propagates in the propagation direction along the first edge while being amplified and is detected at the output line as an amplified signal. A signal incident from the output line is attenuated before emerging at the input resonator.Type: GrantFiled: September 6, 2017Date of Patent: July 28, 2020Assignees: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITY, FRIEDRICH-ALEXANDER-UNIVERSITAT ERLANGEN-NURNBERGInventors: Aashish Clerk, Martin Houde, Florian Marquardt, Vittorio Peano Cavasola

Patent number: 10716707Abstract: Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually undergoing treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.Type: GrantFiled: August 27, 2015Date of Patent: July 21, 2020Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: Robert F.

Patent number: 10690255Abstract: A major challenge for the general use of “lab-on-a-chip” (LOAC) systems and point-of-care (POC) devices has been the generally complex and need for sophisticated peripheral equipment, such that it is more difficult than anticipated to implement low cost, robust and portable LOAC/POC solutions. It would be beneficial for chemical, medical, healthcare, and environmental applications to provide designs for inexpensive LOAC/POC solutions compatible with miniaturization and mass production, and are potentially portable, using compact possibly hand-held instruments, using reusable or disposable detectors. Embodiments of the invention address improved circuit elements for self-powered self-regulating microfluidic circuits including programmable retention valves, programmable trigger valves, enhanced capillary pumps, and flow resonators.Type: GrantFiled: October 17, 2017Date of Patent: June 23, 2020Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: David Juncker, Hosseinali Safavieh

Publication number: 20200093912Abstract: An attenuated Salmonella enterica serovar Typhimurium strain (YS1646) is repurposed to produce a vaccine. Plasmid-based candidates expressing either the TcdA or TcdB RBD were screened. Different vaccine routes and schedules were tested to achieve detectable serum and mucosal antibody titers in C57BL/6J mice. When given in a multi-modality schedule over 1 week (day 0 IM+PO, days 2 and 4 PO), several candidates provided 100% protection against lethal challenge. Substantial protection (82%) was achieved with combined PO TcdA/TcdB vaccination alone (d0, 2 and 4). These data demonstrate the potential of the YS1646-based vaccines for C. difficile.Type: ApplicationFiled: September 19, 2019Publication date: March 26, 2020Applicant: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: Brian J.

Patent number: 10576447Abstract: InGaN offers a route to high efficiency overall water splitting under one-step photo-excitation. Further, the chemical stability of metal-nitrides supports their use as an alternative photocatalyst. However, the efficiency of overall water splitting using InGaN and other visible light responsive photocatalysts has remained extremely low despite prior art work addressing optical absorption through band gap engineering. Within this prior art the detrimental effects of unbalanced charge carrier extraction/collection on the efficiency of the four electron-hole water splitting reaction have remained largely unaddressed. To address this growth processes are presented that allow for controlled adjustment and establishment of the appropriate Fermi level and/or band bending in order to allow the photochemical water splitting to proceed at high rate and high efficiency. Beneficially, establishing such material surface charge properties also reduces photo-corrosion and instability under harsh photocatalysis conditions.Type: GrantFiled: July 31, 2015Date of Patent: March 3, 2020Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: Zetian Mi, Md Golam Kibria, Mohammad Faqrul Alam Chowdhury

Patent number: 10495568Abstract: An apparatus for analysing a sample of granular material, such as soil, is described. An elongated housing has a channel extending therethrough to define an optical path. A cavity is defined within the top of the housing to receive the sample, and a transparent sample-receiving surface is disposed within the cavity at a first elevation from the bottom of the housing. A lens assembly is positioned within the optical path at a second, lower, elevation. The lens assembly magnifies an image formed by light beams reflected by or transmitted through the sample. An image capturing device is disposed across the optical path at a third elevation that is lower than the second elevation. The image capturing device is thus lower than both the lens assembly and the transparent sample-receiving surface. A light source is mounted within the housing to emit light toward the sample-receiving surface.Type: GrantFiled: April 27, 2018Date of Patent: December 3, 2019Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: Viacheslav Adamchuk, Asim Biswas, Long Qi, Maxime Leclerc, Bharath Sudarsan, Wenjun Ji
