Patent number: 8957243Abstract: The present invention provides phosphonium ionic liquids (11) and coatings made therefrom. Highly fluorinated phosphonium ionic liquids based on (11) having been produced exhibiting high thermal stabilities, low melting points and temperature dependent solvent miscibilities. These salts and derivatives of (11) have also been employed in the preparation of superhydrophobic surfaces, indicating that ionic liquids are not only new alternative solvents, but also viable functional materials. All derivatives of (11) form biphasic systems with common laboratory solvents of ranging polarity at room temperature. Based on the solvent miscibility experiments with water and the high fluorine loading, the PILs showed obvious evidence of being hydrophobic. Coatings made with these phosphonium ionic liquids (11), salts and derivatives thereof were superhydrophobic with water contact angles were measured and all of the surfaces were determined to be superhydrophobic with contact angles >150°.Type: GrantFiled: January 28, 2009Date of Patent: February 17, 2015Assignee: The University of Western OntarioInventors: Paul J.

Patent number: 8900840Abstract: The present invention provides a system that has been devised to overcome the two most important limitations for sustained biological hydrogen production, namely contamination of the microbial hydrogen-producing cultures with methane-producing cultures necessitating frequent re-start-up and/or other methanogenic bacteria inactivation techniques, and the low bacterial yield of hydrogen-producers culminating in microbial washout from the system and failure. The system includes a continuously stirred bioreactor (CSTR) for biological hydrogen production, followed by a gravity settler positioned downstream of the CSTR, which combination forms a biohydrogenator. The biomass concentration in the hydrogen reactor is kept at the desired range through biomass recirculation from the bottom of the gravity settler and/or biomass wastage from the gravity settler's underflow.Type: GrantFiled: February 1, 2010Date of Patent: December 2, 2014Assignee: The University of Western OntarioInventors: Hisham Mohamed Hafez, Mohamed Hesham El Naggar, George F.

Patent number: 8870576Abstract: The present invention provides surgical training aids formed from hydrogels and adapted to exhibit realistic mechanical properties mimicking those of real organs. Surgical training aids are preferably fabricated by subjecting a concentration of polyvinyl alcohol to freeze-thaw cycles in a mold designed to approximate the shape of an organ, and process parameters are selected to tailor the mechanical properties of the formed hydrogel to those of the organ simulated by the surgical aid. The mechanical properties of the hydrogel forming the surgical training aid may be tailored by incorporating bacterial cellulose and by applying strain during hydrogel formation, thereby producing controlled anisotropy.Type: GrantFiled: September 22, 2010Date of Patent: October 28, 2014Assignee: The University of Western OntarioInventors: Leonardo Millon, Wankei Wan, Mackenzie Quantz

Patent number: 8839683Abstract: The present invention provides a microscale pressure sensor that exhibits high sensitivity in a small form factor. The sensor is a bridged device in which a photonic crystal waveguide, surrounded by a photonic crystal slab, is suspended over a dielectric substrate. Under applied pressure, the photonic crystal waveguide is deflected toward the substrate, causing a decrease in optical transmission across the waveguide due to the coupling of the evanescent field of the guided mode to the dielectric substrate. In a preferred embodiment, the waveguide is coupled to a photonic crystal microcavity, which increases evanescent coupling.Type: GrantFiled: May 3, 2010Date of Patent: September 23, 2014Assignee: The University of Western OntarioInventors: Jayshri Sabarinathan, Aref Bakhtazad, Xuan Huo, Jeff Hutter

Publication number: 20140177753Abstract: Systems, methods, and devices relating to short range wireless communications. A host device wirelessly communicates with a user device. The transceiver on the host device is of a greater complexity than the transceiver on the user device. The host device performs a number of signal processing steps on data to be exchanged with the user device such that the complexity of the processing to be done by the user device is significantly reduced. This approach thereby reduces the complexity of the transceiver on the user device. The host device processing includes pre-channel equalization and pre-synchronization.Type: ApplicationFiled: December 20, 2013Publication date: June 26, 2014Applicant: The University of Western OntarioInventors: Xianbin WANG, Ahmed Rafaey HUSSEIN
