Abstract

Wide bandgap semiconductors have drawn a lot of attention in power applications due to their superior material properties, such as withstand to high critical electric field so the breakdown voltage is a minimum of 10X higher and thus can be thinner devices because of the 100 times smaller on-resistance than Si. Their significantly smaller conduction and switching losses compared to Si devices enable high-frequency switching leading to size decrease of the overall system. Smart control of wide bandgap devices, by utilizing advanced digital processors, further benefits power application by enabling designs with low parts count, high power density and a low BOM cost. Also, by supporting variable frequency operation and control methodologies, low EMI/RFI and high efficiency can be achieved. Presented will be some benefits of wide bandgap semiconductors and their control with Solantro’s advanced digital power processor (SA4041) for Smart Power Supplies, and other applications.

After the presentation, a tour showing the Smart Grid project together with Solantro’s Power development, operation and testing labs will be conducted. Solantro engineers will be happy to answer questions during the tour.

GNSS
Antennas for Autonomous Vehicles:

What You Need to Know!

 

Precise
and reliable positioning recently became a critical property of autonomous
vehicles like drones, driverless cars and more. Tallysman Wireless will explain
why the GNSS antenna is the most important component for accurate positioning
and will present the challenges of selecting the appropriate GNSS antenna for
diverse types of autonomous vehicles. Multiple properties of a GNSS antenna
like its phase center variation, ability to reject interferences or multipath
and sensibility to its environment will be analysed and guide lines will be
proposed.

 

Refreshments will be served!

BIOGRAPHY:

Julien
Hautcoeur received the M.Sc. degree in radio communication systems and
electronics from the Ecole Polytechnique of the University of Nantes, Nantes,
France, in 2007 and the Ph.D. degree in signal processing and
telecommunications from the Institute of Electronics and Telecommunications of
Rennes 1, Rennes, France, in 2011. In 2011, he was involved in postdoctoral
training at the University of Quebec in Outaouais (UQO), Gatineau, QC, Canada.
His research field was optically transparent antenna systems for telecommunications.
Since 2014 he works at Tallysman Wireless in Ottawa, Canada and specialized in
the design of high performance GNSS antennas and associated electronics.

ABSTRACT:

Over 250 million people in the world are blind or visually impaired. But 75% of visual impairment can be treated or entirely prevented if detected early, monitored effectively, and treated promptly. Various retinal imaging instruments have been developed to assist the screening, diagnosing and monitoring of vision critical eye diseases. These instruments range from traditional ophthalmoscope to digital fundus camera; from ocular tomography (OCT) to laser scanning ophthalmoscope. In this presentation the speaker will attempt to explain the principle of retinal imaging; give an overview on the advances in retinal imaging; and discuss the opportunities for innovation in vision care and retinal imaging.

SPEAKER:

Dr Kexing Liu is the president and CEO of OcuXcel Corporation, a technology company based in Kanata, Ontario, dedicated to providing advanced technology solutions and developing new products from a global tech workforce for ophthalmology and vision health. Kexing received his Ph.D. degree from University of Manchester (UMIST), UK. One of his first professional and technology contribution was in pioneering the integration and qualification of GPS navigation technology into the on-board flight management systems for civil aviation as a project leader at CMC Electronique, Montreal. Later he joined a start-up called Cambrian Systems Corporation, Kanata, He was one of the the principal architects for the world’s first metro DWDM system product – OPTera (OM5K) at Cambrian. The company was later acquired by Nortel Networks. The OM5K as an extremely profitable line of product has generated over US$3 billion revenue for Nortel (now Ciena) since the acquisition. Later on, Kexing had an opportunity to serve as the principal of Mira Connections, a consulting business helping medical device companies on systems engineering and management issues. Most recently Kexing has architected multispectral digital ophthalmoscope for retinal health screening. Kexing has published more than 30 scientific papers on fiber optics and photonics. He is inventor/co-inventor for 17 granted patents ranging from photonics, optical communications systems, control systems engineering, and ophthalmology instruments. Kexing is a senior member of IEEE and is currently serving as the chair of an IEEE Canada committee responsible for outreach.

Abstract

Lightning is one of the primary causes of damage and malfunction of telecommunication and power networks and one of the leading causes of weather-related deaths and injuries.

Lightning is composed of numerous physical processes, of which only a few are visible to the naked eye.

This lecture presents various aspects of the lightning phenomenon, its main processes and the technologies that have been developed to assess the parameters that are important for engineering and scientific applications. These parameters include the channel-base current and its associated electromagnetic fields.

The measurement techniques for these parameters are intrinsically difficult due to the randomness of the phenomenon and to the harsh electromagnetic environment created by the lightning itself.

Besides the measurement of the lightning parameters, warning and insurance applications require the real-time detection and location of the lightning strike point. The main classical and emerging lightning detection and location techniques, including those used in currently available commercial lightning location systems will be described in the lecture. The newly proposed Electromagnetic Time Reversal technique, which has the potential to revolutionize lightning location will also be presented.
