| 20100192720 | Parallel Kinematic Structure - A parallel kinematic structure comprises at least two kinematic chains being functionally arranged in parallel. Each of the two kinematic chains has, at a moveable end thereof, at least one degree of freedom, and comprising a passive anti-planar joint arrangement having a translational degree of freedom and two rotational degrees of freedom. Each anti-planar joint arrangement has an input section and an output section. At least one of the kinematic chains comprises a planar joint arrangement having at least one of at least one translational degree of freedom and a rotational degree of freedom, the planar joint arrangement having an output section. Further, the planar joint arrangement is adapted for active movements in at least one of its degrees of freedom. The input section of the anti-planar joint arrangement and the output section of the respective planar joint arrangement are coupled. The parallel kinematic structure further comprises a moveable end-effector section coupled with the output sections of the anti-planar joint arrangements. | 08-05-2010 |
| 20100032255 | Force-feedback device and method - A force-feedback device comprising a first member; a first kinematics bond being coupled with said first member; said first kinematics bond being constructed to provide at least one degree of freedom for movements of said first member; said first kinematics bond comprising a braking device being constructed to constrain movements of the said first member in at least one of said at least one degree of freedom; and a energy storing/release device being constructed to store energy in response to a movement of said first member in at least one of said at least one degree of freedom constrained by said braking device. A method of providing force-feedback including constraining a movement of a member of a haptic device in at least one degree of freedom; moving the member, by an externally applied force, in at least one of the at least one constraint degree of freedom; storing energy generated by the moving of the member; determining a force required to move the member in at least one of the at least one constraint degree of freedom; releasing at least a portion of the stored energy to generate at least a portion of the required force and transmitting the at least a portion of the required force to the member. | 02-11-2010 |
