  • Patent number: 7736394
    Abstract: The actuated leg prosthesis comprises a knee member, a socket connector provided over the knee member, an elongated trans-tibial member having a bottom end under which is connected an artificial foot, and a linear actuator. A first pivot assembly allows to operatively connect the trans-tibial member to the knee member. A second pivot assembly allows to operatively connect an upper end of the actuator to the knee member. A third pivot assembly allows to operatively connect a bottom end of the actuator to the bottom end of the trans-tibial member. The prosthesis can be provided as either a front actuator configuration or a rear actuator configuration.

  • Patent number: 7597017
    Abstract: The present invention discloses locomotion simulator comprising a base having a surface movable along a base axis, a post mounted to the base a pelvic structure and a hip-thigh mechanism wherein coordinated displacement of the pelvic structure and pivoting of the thigh segment assembly simulates patterns of locomotion. The pelvic structure includes a first support movably mounted to the post, the first support allowing a displacement of the pelvic structure along a first pelvic axis generally perpendicular to the base axis and a second support movably mounted to the first support, the second support allowing a displacement of the pelvic structure along a second pelvic axis generally parallel to the base axis.

  • Publication number: 20060201757
    Abstract: The braking device is provided a set of shape memory alloy activators positioned, in an agonistic-antagonistic configuration on each side of a brake lever. Braking and releasing phases are dictated by the austenitic transformation of the shape memory alloy activators. During brake activation, shrinking of the braking activator brings the friction pad in contact with a rotating drum creating a braking friction torque. Once the brake has been activated, deformation of a flexible fiberglass component prevents brake releasing by applying sufficient normal force between the drum and the friction pad. Conversely, upon heating of the releasing activator, the pad looses its grip and the drum is free to rotate.

  • Patent number: 5047147
    Abstract: Artificial kidney of the single-needle type, incorporating an extracorporeal blood circuit provided with a haemodialyser (13) or haemofilter (31) positioned between two blood circulation pumps (12, 19). This circuit is also provided with a bubble trap (18) and a safety clamp (26) and means for perfusing quantities of liquid which are capable of being relatively large. The perfusing means comprise a reservoir (23) and a perfusion pump (24) the motion of which is under the control of the sequential motion of one of the two blood circulation pumps (12, 19) and also comprise a conduit connecting the reservoir (23) to the extracorporeal blood circuit by way of the perfusion pump (24).
