Patent number: 11946878Abstract: A device for unidirectional propagation of microwaves comprises a resonant microwave structure arranged to transmit microwaves between two ports and a magnetic source arranged to provide a generally static magnetic field and to have a resonant frequency distinct from that of the microwave structure, which is disposed adjacent the microwave structure so as to be located in presence of electromagnetic fields emanating from the transmitted microwaves such that the magnetic field interacts with the electromagnetic fields of the microwaves so as to form a set of hybridized resonant frequencies at which zero intrinsic damping exists, one of the set of hybridized resonant frequencies being a real eigenvalue providing the unidirectional propagation from one of the first and second ports to the other. A related method comprises arranging the magnetic source at a prescribed position where the real eigenvalue matches the frequency of an input signal applied at a selected port.Type: GrantFiled: December 10, 2020Date of Patent: April 2, 2024Assignee: University of ManitobaInventors: Can-Ming Hu, Yi-Pu Wang, Yongsheng Gui, Mun Kim

Patent number: 11746030Abstract: Aerobic granular sludge (AGS) is an energy efficient and compact biological wastewater treatment process. There is only one commercially available AGS technology which utilizes sequencing batch reactors (SBR). Many existing wastewater treatment facilities consist of long, continuous flow reactors that would not be readily suitable for retrofit to SBR. Therefore, a continuous flow process is preferred for municipalities that cannot economically invest in the only commercially available SBR technology (i.e., Nere-da®). Lab- and pilot-scale experimentation has demonstrated that stable granulation can be achieved in a continuous flow configuration GT suitable for retrofit into existing infrastructure. An anoxic/anaerobic/aerobic configuration can be designed and stably operated for conversion of flocculent biomass to AGS Preliminary pilot-scale results on primary effluent from a municipal wastewater treatment facility indicated that granules of 0.2-0.Type: GrantFiled: March 28, 2019Date of Patent: September 5, 2023Assignee: University of ManitobaInventors: Tanner R.

Patent number: 11692972Abstract: An ultrasonic sensing technique and a signal interpretation method based on a spectral element multiphase poromechanical approach overcomes critical gaps in permafrost, frozen soil, and saturated soil characterization. Ultrasonic sensing produces high-quality response signals that are sensitive to the soil properties. A transfer function denoting a ratio of induced displacement and applied force in the frequency domain, is independent of the distribution of the stress force applied by the transducer to the sample, and allows interpretation of the measured electrical signal using a theoretical transfer function relation to efficiently determine the most probable properties from response signals using an inverse spectral element multiphase poromechanical approach. This ultrasonic sensing technique enables rapid characterization of soil samples in terms of both physical and mechanical properties.Type: GrantFiled: July 9, 2021Date of Patent: July 4, 2023Assignee: University of ManitobaInventors: Pooneh Maghoul, Hongwei Liu, Ahmed Shalaby

Patent number: 11513056Abstract: A dual light source lens-free dielectrophoresis (DEP) flow cytometer for massively parallel single cell analysis. Each cells dielectric is inferred from measuring their altitude and subsequently velocity change due to DEP actuation in a microfluidic channel. Dual LED sources facilitate velocity measurement by producing two shadows for each cell passing through the channel. These shadows are detected using a linear optical array detector. Massively parallel analysis is possible as each pixel of the detector can independently analyze the passing cells. The DEP cytometer is composed of simple modular components and has the potential to be scaled to achieve a significantly high throughput label-free single-cell analyzer.Type: GrantFiled: October 2, 2020Date of Patent: November 29, 2022Assignee: University of ManitobaInventors: Douglas Thomson, Gregory Bridges, Elham Salimi, Azita Fazelkhah, Samaneh Afshar Delkhah, Nicholas Durham

Patent number: 11513052Abstract: Determination of transport phenomena properties in porous media is one major objective of core analysis studies in petrophysics, reservoir engineering, and groundwater hydrology. Porosity measurement may be considered as a key factor to identify the hydraulic performance of a low permeable porous medium (e.g. rock or concrete). Additionally, the rate of absorption under pressure depends on the permeability, which is related to the connectivity between the existing pores within the porous structure. An alternative Gas Expansion Induced Water Intrusion Porosimetry (GEIWIP) method and apparatus is useful to measure the total porosity and pore size distribution, using a gas/water intrusion apparatus for water tight materials.Type: GrantFiled: October 24, 2019Date of Patent: November 29, 2022Assignee: University of ManitobaInventors: Hartmut Michael Hollander, Miad Jarrahi, Douglas W.

Patent number: 11304958Abstract: Described herein is the development of synthetic routes to produce a wide variety of substituted phenanthridines, specifically, multidentate phenanthridine-containing ligand frameworks capable of anchoring to Pt via more than one binding site and with the phenanthridinyl moiety co-planar to the coordination plane of Pt. The multidentate chelation is designed to attenuate the reactivity of the platinum complex in vivo, and ultimately help mitigate side effects. In addition, the geometry of phenanthridine binding to the metal centre is altered compared to in phenanthriplatin, thanks to the constraints of the ligand geometry. By enforcing coplanar binding with the metal's square planar coordination plane, these compounds exhibit altered modes of activity, and should hence enhance/change the spectrum of activity of our prodrug candidates compared with phenanthriplatin.Type: GrantFiled: May 24, 2019Date of Patent: April 19, 2022Assignee: University of ManitobaInventors: David E. Herbert, Issiah B. Lozada, Bin Huang, Yaorong Zheng, Zihan Qiu
