A detector indicating ice formation on the wing of an aircraft or any planear surface, based on a thread-like or a tape-like transducer, through which a supersonic signal is transmitted at one end. The attenuation of the signal having passed through the thread is measured with a receiver at the opposite end while the thread is simultaenously being heated such that ice that may surround it melts again, the attenuation thus resuming its initial level.

Why it's free to use
- Filed September 8, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 8, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 8, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
