Open the CIPO recordAbstract From the Canadian patent
A spectroscopy instrument that uses spectra produced from random binary sequence modulated data. Statistical estimation techniques are used to achieve resolution enhancement, while properly accounting for the Poisson noise distribution and other artifacts introduced by a modular or "chopper" or other system components. Indeed, a resolution similar to that of modern spectrometers can be achieved with a dramatic performance advantage over conventional, serial detection analyzers. Both static and dynamic behaviors are theoretically or measured experimentally accounted for in the model as determined. In one embodiment, the finite penetration of the field beyond the plane of the chopper …

Why it's free to use
- Filed June 7, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 7, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
