Abstract From the Canadian patent

An apparatus (10) for analyzing lubricant oils and functional fluids includes an optical emission spectrometer (OES) (26) having a substantially continuously valued wavelength versus intensity output (140). The OES (26) analyzes light captured from a spark emission stand (58) through which the fluid sample is flowed. An expert system (160-172) operates according to a set of Rules, and generates diagnostic text (174) for an operator based on the information about the fluid sample provided by the OES (26) and other measurement devices. The apparatus (10) is reduced in size weight and cost.

Why it's free to use

  • Filed August 12, 1999 and granted October 25, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 12, 2019.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 12, 2021.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
