Abstract: A passive haptic interface includes a first element which is rotatably movable about an axis or translatably movable along an axis, the first movable element rotating or moving opposite a second fixed element. The first movable element has a first plurality of magnetic poles spaced periodically at a pole pitch Ps and in the direction of movement, and the second fixed element has a second plurality of magnetic poles periodically spaced at a pole pitch Pr and in the direction of movement, where Ps and Pr are different numbers. A periodic stress is created by the magnetic interaction between the first movable element and the second fixed element in a period Pt. The pole pitches Ps and Pr are chosen such that Pt is strictly less than the smallest of the pitches Ps and Pr.

Abstract: An adjustable force device comprises a member that is mechanically guided for allowing a displacement according to a predetermined trajectory, and means for magnetically indexing the displacement by the magnetic interaction between a first ferromagnetic structure and a second ferromagnetic structure integral with a magnet, wherein the magnet is at least partially surrounded by an electric coil that modifies the magnetization of the permanent magnet according to the direction and the amplitude of the electric current flowing in the coil.
