Open the CIPO recordAbstract From the Canadian patent
A man-machine interface is dis-, closed which provides force and texture information to sensing body parts. The interface is comprised of a force actuating device (900) that produces a force which is transmitted to force applying device (902). The force applying device applies the generated force to a pressure sensing body part. A force sensor (909) on the force applying , device measures the actual force applied to the pressure sensing body part, while angle sensors (911) measure the angles of relevant joint body parts. A computing device (911), uses the,joint body part position information a determine a desired force value to be applied to pressure sensing body part. The computing device …

Why it's free to use
- Filed January 30, 1991 and granted July 24, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 30, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 30, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
