(2000 – 2005)
Ontario Hydro Technologies (OHT), 800 Kipling Avenue, Toronto (Dr. S. Peralta, Electrical Systems Technology): A long-term relationship with OHT on depth profilometric evaluation of laser processed steels ended in 1997 with Hydro’s restructuring. (1990’s)
Imperial Oil, Sarnia, Ontario (Dr. Terrence Ashe, Sr. Research Chemist): A novel pyroelectric thermal-wave resonator cavity was introduced and tested successfully with Imperial’s gasolines to ascertain its suitability as an on-site sensor of quality control at the pump level. (1990’s)
Union Carbide, Washougal, WA (Dr. Milan Kokta, Crystal Growth Div.): Photopyroelectric spectroscopic methods developed at the Unviersity of Toronto were used to monitor the quality of Union Carbide’s Ti:Sapphire laser rod surface polishes. (1992-95)

Edison Welding Institute, Columbus, OH (Dr. Bahram Farahbakhsh, NDE Group Leader): Thermal-wave NDE characterization of thermal-barrier coatings was tested successfully. (1998- 2000).
Sputtek, Inc., Etobicoke, ON (Dr. Lee Segal, President): We have developed an optical thermometer based on laser thermoreflectance and thin-film interferometry principles for remote, non-comtact monitoring of sputtered TiN coating temperatures and film growth in reactor chambers under vacuum. This technology is now at the Market Readiness phase under full development for industrial use by Sputtek and other coating companies, funded by Materials and Manufacturing Ontario. (2000 – 2006).
Metex, Inc., Etobicoke, ON (Mr. S. Bawa, President): A case-depth steel hardness monitoring instrument has been developed for fast, real-time control of the hardening process in industrial steel screws heat-treated by the Company, to replace slow and time-consuming indenter hardness measurements. The technology is the outcome of several years of fundamental thermal-wave depth-profilometric inverse-problem studies. (2007 – 2009).
Four Cell Consulting, Toronto, ON (Dr. Stephen Abrams, DDS): A combined laser-based photothermal radiometric and modulated luminescence technology has been developed for monitoring early sub-surface carious lesions in teeth (enamel or dentin) occlusally or interproximally. The technology has exhibited sensitivity better than dental x-rays and superior lesion contrast without the risk of ionizing radiation. This technology has resulted in a Mandelis-Abrams partnership and the establishment of Quantum Dental Technologies,Inc., in Toronto. It markets the CanaryTM early caries detection system (see entry # 14 below).
Stackpole International, Mississauga, ON (Roger Lawcock, Director of Technology): A laser photothermal technqiue for monitoring cracks in “green” and sintered automotive parts and sprockets was developed. The technique was proven to be able to detect cracks at inner corners and on flat surfaces of Stackpole’s green (pre-sintered) parts, unlike other NDT techniques. A systematic study of the photothermal signal behavior on the nature of these cracks was completed in 2009. That study led to a new collaboration for developing a crack imaging system for the Company based on the thermal-wave radar imager introduced in the CADIPT in 2010.
Ultrasonix Medical Corp., Richmond, British Columbia, Canada: Development of a photoacoustic laser-based imager using a transducer phased array and co-registration of ultrasonic and photoacoustic images.

Quantum Dental Technologies (QDT) Inc., Toronto, ON. As a UofT spin-off company, QDT is a natural industrial collaborating partner with the CADIPT (Dr. Mandelis is the CTO of the Company). Primary contact person: Dr. Stephen Abrams, CEO. QDT, Inc., has supported several funded projects as an industrial partner with both in-kind and cash contributions. (2007 – )
MDS Coating Technologies, St. Laurent, Quebec. A preliminary (pilot) project on MDS multi-layered thermal barrier coating thermophysical property measurements was completed (2011).
Avio S.p.A., Torino, Italy. Avio is Italy’s largest aerospace company. A collaboration with the CADIPT to develop steel microhardness non-destructive thermal-wave inspection techniques for large case depths in aerospace gears has produced very promising preliminary results using the thermal-wave pulse-compression radar pioneered in the CADIPT. (2010 – )
Pratt and Whitney Canada, Toronto, ON. A collaboration with PWC was developed in 2013-14 for dynamic non-destructive thermographic imaging of nanocoating flaws for aerospace components. The research is currently branching out into a new laser ultrasonic (photoacoustic) method for monitoring the stress state in PWC components coated with these nanocoatings which are used to extend fatigue life of crucial aerospace engine components (2013 -).
Alcohol Countermeasure Systems, Toronto, ON. A joint project is being pursued to develop an ethyl alcohol sensor for use in alcohol offenders’ vehicles, as well as for equipping the cars of the general public in order to make factual decisions on whether or not to drive after drinking.
