Open the CIPO recordAbstract From the Canadian patent
The present invention comprises devices and methods that deliver electromagnetic radiation (EMR) from an emitter to a target and employ laser or sonar (a sensing method) to measure distance between target and the EMR emitter and automatically signal the emitter control circuitry to vary either the position or the power output of the emitter (as appropriate) in order to ensure that the effect of any change in distance on the energy incident to the target is compensated rapidly and automatically. In a preferred embodiment the device is a hand-held, non-contact heatbeam dolorimeter.

Why it's free to use
- Filed October 26, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 26, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 26, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
