Open the CIPO recordAbstract From the Canadian patent
So as to shape the spatial amplification characteristic of an acoustical to electrical converter arrangement at least two sub-arrangements (I II) of , converters are provided, generating different spatial amplification characteristics. Frequency domain converted signals (S1) which are proportional to the output signals of the sub-arrangement are compared in a unit (39) on respective spectral frequencies (fs) and there is generated at the output of the comparing unit (39) a binary spectral comparison result signal (A39). Signals (S2) which are as well proportional to the output signals of the sub-arrangements (I, II) are fed to a switching unit (41). For each spectral frequency (fs) …

Why it's free to use
- Filed March 3, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 3, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 3, 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.
