Open the CIPO recordAbstract From the Canadian patent
Several MEMS-based methods and architectures which utilize vibrating micromechanical resonators in circuits to implement filtering mixing, frequency reference and amplifying functions are provided. Apparatus is provided for selecting at least one desired passband or channel in an RF transmitter subsystem utilizing a bank of vibrating micromechanical devices. One of the primary benefits of the use of such architectures is a savings in power consumption by trading power for high selectivity (i.e high Q). , Consequently, the present invention relies on the use of a large number of micromechanical links in SSI networks to implement signal processing functions with basically zero DC power …

Why it's free to use
- Filed April 20, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 20, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 20, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
