Abstract From the Canadian patent

A system for sensing the load on a load supporting beam of a vehicle. The system comprises an elongate sensor beam and means for releasably securing a pair of opposite end sections of the sensor beam to a load supporting beam of a vehicle. The sensor beam is secured to the load supporting beam so that a longitudinal axis of the load sensor beam is aligned with a longitudinal axis of the load supporting beam. A plurality of strain gauges are attached to a central section of the load sensor beam. The strain gauges are connected so that each of them can transmit an output signal processor.

Why it's free to use

  • Filed October 30, 1992 and granted December 6, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 30, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 30, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
