In an oscillator circuit (VCOS) that contains an oscillator crystal having characteristic information (ki) individually associated to the oscillator crystal, the crystal signals or digital clock signals (ts) are conducted to an output (A). A memory that stores the individual characteristic information (ki) of the oscillator crystal is fashioned in the oscillator circuit (VCOS) such that the individual characteristic information (ki) of the oscillator crystals are moved to at least one output (A AM) of, the oscillator circuit (VCOS) as analog digital, coded digital or, modulated signals (msp).

Why it's free to use
- Filed January 27, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 27, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 27, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
