Abstract From the Canadian patent

A synchronized drive for a slide with a slip clutch which dissipates excess energy in an overload or crash situation to prevent damage to the mechanism. The slip clutch is coupled between a servo motor and a gear reducer to dissipate excessive force during a crash or an overload condition. A position feedback transducer is coupled to the gear reducer downstream of the clutch to maintain synchronization even after a crash, or overload condition without requiring any re-homing sequence.

Why it's free to use

  • Filed March 13, 1992 and granted January 4, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 13, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 13, 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.
