Methods of fluid handling are disclosed. According to one method a tip of a , nozzle is moved below a surface of the fluid to be handled. A pump fluidly associated with the nozzle is energized to move fluid into the nozzle. A pressure transducer fluidly associated with the nozzle is energized to monitor pressure within the nozzle. Pressure within the nozzle is substantially continuously monitored with the pressure transducer during operation of the pump. Based on the substantially continuously monitored pressure within the nozzle, it is determined whether movement of fluid into the nozzle is intended or unintended. Similar methods may be used to move fluid out to the nozzle.

Why it's free to use
- Filed December 4, 1996 and granted July 29, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 4, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 4, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
