Kanstad Teknologi is a family-owned R&D company, where I develop new technologies, do my science and hold my patents.

The company's main technology is in infrared gas sensing, based on patents
on incandescent infrared radiation sources. This started in the early 1980's with the development of infrared gas sensors for the Norwegian off-shore oil industry. The patents and sensors were licensed to another Norwegian company, as Kanstad Teknologi does not itself manufacture any
"My" radiation-cooled infrared radiation sources are now used in many -
and maybe most - non-laser infrared gas sensors in the world.
Later in the 1980's I invented and - through a daugther company - developed a secure method and accompanying equipment to
discriminate between genuine and counterfeit banknotes, on a project
with the money-printing Bank of Norway. This development relied on a
combination of laser and infrared technology. That technology is now
used not only for all Norwegian banknotes made since 1984; from the 1990's
most bank notes in the western world including US banknotes use this
technology for making counterfeit-secure banknotes and to discriminate
From the year 2000 we have operated a subsidiary in Canada by the name
of Comag IR Technology Inc., located in Winnipeg, Manitoba. Comag has
developed new and leading infrared gas sensors, mostly for carbon dioxide gas. Those sensors have been installed in numerous universities and schools across Canada, saving large amounts of energy (and millions of dollars) by demand-controlled-ventilation, i.e. ventilate only when required by room occupancy as indicated by the concentration of carbon dioxide gas. That is probably the most effective
energy-savings measure for North-American buildings; Comag has been in the lead for promoting this approach.
Based on a new Canadian patent for more advanced infrared gas sensing,
we are now considering where to apply this new sensor technology.
