57)Abstract, A variable length cache system (58 60) keeps track, of the amount of available space on an output device (10). The capacity of the cache system (60) is continuously increased so long as it is less than the available output space on the output unit (10). Once the size of the cache system exceeds the available output space on the output unit (10) which is less than the total space available on the output unit (10) by a predetermined amount, the contents of the cache memory (60) are flushed or written to the output device (10) and the size of the cache memory (60) is reduced to zero.

Why it's free to use
- Filed July 13, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 13, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 13, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
