Generation of few photons and photon pairs with engineered beams carrying angular momentum

Cylindrical vector beams (CVBs) are a class of non-conventional beams of laser light that exhibit spatially varying polarization properties and zero intensity along the propagation axis. CVBs have received significant interest due to their peculiar focusing properties when used in combination with high numerical aperture optics. CVBs are also especially important at the limit of few photons/photon pairs for applications in quantum information processing and quantum data storage.

Experimental Study on Vectorbloc Connection Used in Modular Construction

Modular construction has been gaining its popularity and momentum because it is a cheaper and faster way to build buildings and other structures. Vectorbloc Corp., located in Toronto has developed the concept of steel tubular modular construction using hollow structural steel (HSS) members. This modular construction will use various connectors and assemblies.

Design and implementation of wideband and low-side-lobe-level antenna array in LTCC technology for automotive millimeter-wave radar sensor applications

This project is a collaboration between MMSENSE Technologies and the Centre for Intelligent Antenna and Radio Systems (CIARS) at the University of Waterloo to research, investigate, and design an integrated radar module at millimeter-waves.

Investigation and Implementation of Integrated Electronic Scanning Automotive Radar Sensor front-end module at 77/79GHz band for Short and Long Range, High Angle and Range Resolution detection

The main objective of this project is to investigate, design, fabricate and characterize an integrated front end module for next generation of automotive radar sensors, which have the ability of pedestrian detection and detecting short-range and long-range objects
around the car. To meet such requirements and to reduce the size of the radar sensor, next generation of automotive radar sensors should be designed at millimeter wave (76-81 GHz) with sufficiently low production cost for mass market. This introduce several research
challenges in both transceiver and antenna array.

Towards the commercialization of a robotics-assisted rehabilitation platform for stroke therapy of upper limb

Stroke is the primary cause of physical disability resulting in motor dysfunction. Rehabilitation robots are employed to automate repetitive goal-oriented tasks, and strengthen neural pathways. The portable robot built by our team in collaboration with Quanser can be programmed to aid therapists, and assist upper-limb movements to deliver rehabilitation. In this project, various limitations that currently exist are overcome. First, movement assessment in rehabilitation is usually subjective, and lacks quantitative measures so adding proper sensing mechanisms bridges this gap.

3D object detection and pose estimation using RGBD cameras

3D object detection and pose estimation (ODPE) is an important area in computer vision, which has many real world applications such as robotics and augmented reality. Estimating an accurate pose from RGB cameras alone is challenging. Given the increased popularity of RGBD sensors, such as Microsoft Kinect, we propose a hybrid method for ODPE based on both RGB and depth (3D surface) information. The additional depth information is expected to provide significant improvements in both speed and accuracy of the resulting system.

Development of a slit die system for on-line rheological measurements of polymeric melts

Our industry partner, EHC GLOBAL, is a world leader in the design, manufacture and sale of escalator handrails products including recyclable handrail that features built-in antimicrobial properties and the ability to display custom graphics. They also deal in many other products such as escalator safety brushes, urethane rollers and engineered polymer products and are continuing to introduce new products in the market. However, escalator handrails continue to be one of their major product lines, which they consistently look at improving the performance of this product.

Development of lead-free solder alloys for electronic assembly Year Two

Recent environmental concerns and legislations over the use of lead are driving the microelectronics industry towards intensive search for lead free solder alloys in electronic packaging. Among many lead free solders, Sn-Cu-Ag system has been regarded as the most promising and attractive candidate alloy system for the conventional Sn-Pb solder alloys, owing to its wettability and mechanical properties.

Feasibility Study: Class E/F Amplifiers for driving therapeutic ultrasound transducers

The project involves the development of a power amplifier for driving therapeutic ultrasound transducers such as those used in treating cancer and inducing blood coagulation. In particular, the design will make use of a unconventional amplifier topology, class E/F, and advanced GaN FET technology in order to maximize amplifier efficiency. High efficiency amplifiers are important to reduce the number of fans and heat sinks needed in the ultrasound console, allowing the system to be cooler, lighter, lower cost and more portable.
