Open the CIPO recordAbstract From the Canadian patent
A signal and noise processor and method for signal and noise processing that employs a D Scale, which assigns the results of arithmetic operations to a set of values of controlled density and value. The signal processor that employs repetitive mapping calculations based on a D Arithmetic has two components. The first is its set of mappings from each pair of points in a D Scale into a point in a D Scale. Thus, the processor generates a set of predetermined arithmetic operation mappings, stored in a computer database or its equivalent. The second component is a map of measured values into D Scale , points. The minimum resolution of resolution of a D Arithmetic is determined by the …

Why it's free to use
- Filed October 17, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 17, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 17, 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.
