Open the CIPO recordAbstract From the Canadian patent
A vehicle engine throttle valve control device (10;121) is applied intermediate the vehicle operator's accelerator pedal (14) and the engine's throttle body (12) to selectively override or modify the operator's ability to control vehicle/engine speed and to assert independent control thereof as a function of various input parameters (49,50,52,54). Linkages (26,28) interconnect opposed ends of a lever (18;136) respectively, with accelerator and throttle. The lever rotates upon a pivot (20:126) which is selectively displaceable to effectively shorten or lengthen the linkage in response to an operator independent signal from a control circuit (42).

Why it's free to use
- Filed June 26, 1990 and granted December 15, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 26, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 26, 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.
