Open the CIPO recordAbstract From the Canadian patent
A gimballed vibrating wheel gyroscope (10) for detecting rotational rates in inertial space. The gyroscope (10) includes a support (20) oriented in a first plane and a wheel assembly (12) disposed over the support (20) parallel to the first plane. The wheel assembly (12) is adapted for vibrating rotationally at a predetermined frequency in the first plane and is responsive to rotational rates about a coplanar input axis (32) for providing an output torque about a coplanar output axis (34). The gyroscope (10) also includes a post assembly (18a, 18b) extending between the support (20) and the wheel assembly (12) for supporting the wheel assembly (12). The wheel assembly (12) has an …

Why it's free to use
- Filed May 8, 1996 and granted August 7, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 8, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 8, 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.
