Hydraulic anti-roll bar link
ActiveUS12545072B2Interconnection systemsResilient suspensionsClassical mechanicsSuspension (vehicle)
An anti-roll bar link for a vehicle suspension may be positioned between an anti-roll bar and an articulating arm. The link selectively transfers movement of the arm to the bar, depending on a locked or unlocked state. The link includes a body interfacing a slidable shaft. A valve selectively controls flow of a damping fluid between an inner chamber of the body and a remote chamber. In the locked state, flow of the damping fluid is restricted at least in a direction from the inner chamber to the remote chamber, and movement of the arm is transferred through the link to the bar. In the unlocked state, flow of the damping fluid is permitted in this direction, and movement of the arm causes the shaft to translate with respect to the body such that at least a portion of the movement is not transferred to the bar.

Self-adjusting socket for lower limb prosthesis
The present disclosure describes self-adjusting sockets for lower limb prostheses in which each step transmits motion to a resilient resistive element coupled to an actuator configured to cycle between a rest position and an actuated position. The resistive element can transmit the motion to the actuator to cycle the actuator. Each cycle of the actuator acts through a mechanical linkage to tighten the socket around the residuum, until a desired threshold tightness on the residuum is reached. After the threshold tightness is reached, the resistive element yields and absorbs the motion rather than transmitting the motion, so that the actuator ceases to cycle on each step, preventing further tightening beyond the threshold.
