Detector For Faster Than Nyquist Transmitted Data Symbols

Overview The invention relates to a data transmission technology, known as faster-than-Nyquist (FTN) signaling. When data pulses are transmitted at FTN signaling rate, inter-symbol interference (ISI) must be removed at the receiver using a detector to prevent an increase in bit errors. This allows for increasing the number of transmit bits within the same bandwidth and using the same transmission power of conventional Nyquist signaling. The inventors developed a FTN signaling detector for ultra-high-order quadrature-amplitude modulation (QAM). Simulation results show that this detector achieves excellent performance for ISI removal and reconstruction of the transmitted data symbols, at a very low computational effort, compared to the existing detectors.

Independent Control of a Reflected Electromagnetic Wave’s Magnitude and Phase

Overview Systems and methods relating to independent control of a reflected electromagnetic wave’s phase and magnitude.  A reflective unit cell with independently controllable resistance and capacitance allows for control of the magnitude and phase of the reflected wave.  In one implementation, the unit cell uses coupled resonators, with each resonator having independently controllable parameters.  The coupled resonators may be a dipole ring resonator nested with a split ring resonator.  The dipole ring resonator is loaded with a tunable resistive element while the split ring resonator is loaded with a tunable capacitor.  By independently adjusting the resistance and the capacitance of the resonators, the magnitude and phase of the reflected wave can be controlled.

Aptamers as a Therapeutic Tool to Prevent Protein Aggregation In Neurodegenerative Disease

Overview We have discovered DNA aptamer sequences that bind to different alpha-synuclein morphologies. Notably, we have found one sequence that binds to alpha-synuclein monomers and inhibits the formation of larger oligomers and fibrils when tested in vitro. We have packaged this aptamer in a vehicle that was capable of crossing the blood brain barrier and tested its binding to alpha synuclein in a mouse model of Parkinson’s disease. Using immunofluorescence, we were able to confirm both the delivery of the fluorescently labelled aptamer and that the aptamer co-localizes with an antibody specific for phosphorylated alpha synuclein monomer.

Root Exudate-Activated System for Agrochemical Delivery

Overview A system for delivering fertilizer to the roots of a plant includes coated fertilizer particles. The coating can include a cellulose derivative, a fatty acid, and a component, such as an aptamer, which binds specifically to a material, such as serine, which is released by the roots of the plant when the plant is actively taking up nutrients from the soil. The permeability of the coating increases when the coated particles are exposed to the material released by the roots of the plant. Thus, nutrient release from the coated fertilizer particles is synchronized with uptake of the nutrients by the plant during active growth. Advantages of the system may include one or more of improved nitrogen use efficiency by the plant, improved crop productivity, and/or reduced leaching of fertilizer from the soil.

A Method for Prevention of Ingress of Hydrogen Isotopes and Their Removal from Components Made from Hydride Forming Metals and Alloys
Overview Hydrogen in metals is sometimes a problem because of embrittlement, and methods are sought to reduce the concentration and ingress of hydrogen. Specifically, by way of an example that is not meant to be limiting, a method is disclosed to reduce the rate of ingress of hydrogen isotopes and their subsequent concentrations in zirconium alloy pressure tubes in a CANDU reactor where they are joined to the stainless-steel end-fitting, by the addition of a hydrogen getter to the outboard portion of the end fitting. The hydrogen getter can be any material that has a lower chemical potential for hydrogen than zirconium and can be attached to the end fitting so that a free path for hydrogen movement between the zirconium, steel, and getter is produced. Suitable candidate getter materials include zirconium, titanium, niobium, hafnium, vanadium, or yttrium, as metal, metal alloys or metal composites.

Passive Haptic Feedback Input Device
Overview HaptoBend is an original device for providing general passive haptic feedback (PHF) in virtual reality (VR). HaptoBend has a number of hinged panels that allow the device to be bent into a physical shape representative of a virtual object. Sensors associated with each of the hinges provide information indicative of the rotational configuration of the hinges and so, the passive haptic feedback device. The hinged panels allow it to provide PHF for a variety of virtual objects by transitioning between 2D, plane-like shapes, and multi-surface 3D shapes. Through its shape-changing capabilities, HaptoBend avoids the size, complexity, and cost of general purpose haptic systems. HaptoBend is simple, yet diverse by leveraging the dominance of human vision over other senses to provide realistic PHF with physical approximations of virtual objects. HaptoBend’s ability to bend also means bending interactions can be applied to normally rigid objects in VR while maintaining realistic PHF.

High-Precision Road Users Detection using WIFI and Bluetooth Signals
Overview A user of a computing device may be detected, and their location determined, based on radio frequency signals transmitted by the computing device.  The RF signals may be for example Bluetooth or Wi-Fi signals that are received by a localization device.  The localization device comprises a plurality of RF receivers for receiving the transmitted RF signals.  The RF receivers are synchronized by a single local master clock signal, allowing the localization device to determine the computing device’s location based on a time difference of arrival of the transmitted signal at the receivers.
