Abstract
A permanent magnet actuation mechanism may include a first permanent magnet magnetized along a first axis and rotatable about a first rotational axis perpendicular to the first axis, a second permanent magnet magnetized along a second axis and rotatable about a second rotational axis perpendicular to the second axis. The first rotational axis is parallel with the second rotational axis. The mechanism further comprises a mounting structure configured to position the first permanent magnet at a first distance from the second permanent magnet along a main axis perpendicular to the first rotational axis and the second rotational axis.

A permanent magnet actuation mechanism, comprising:
- a first permanent magnet magnetized along a first axis, the first permanent magnet rotatable about a first rotational axis perpendicular to the first axis, the first permanent magnet rotatable between a first primary position and a first secondary position, the first secondary position corresponding to a position of the first permanent magnet rotated by 180° about the first rotational axis, with respect to the first primary position;
- a second permanent magnet magnetized along a second axis, the second permanent magnet rotatable about a second rotational axis perpendicular to the second axis, the second permanent magnet rotatable between a second primary position and a second secondary position, the second rotational axis parallel with the first rotational axis, the second secondary position corresponding to a position of the second permanent magnet rotated by 180° about the second rotational axis, with respect to the second primary position;
- a mounting structure configured to position the first permanent magnet at a first distance from the second permanent magnet along a main axis perpendicular to the first rotational axis and the second rotational axis,
- wherein the first permanent magnet and the second permanent magnet are magnetized along the main axis, the first permanent magnet and the second permanent magnet configured to face each other with opposite poles in the corresponding first initial position and the second initial position,
- wherein rotation of the first permanent magnet about the first rotational axis from the first primary position to the first secondary position in a first direction actuates a rotation of the second permanent magnet about the second rotational axis from the second primary position to the second secondary position in a second direction, the second direction opposite the first direction.
A permanent magnet actuation mechanism, comprising:
- a master permanent magnet rotatable about a first rotational axis, the master permanent magnet magnetized along a main axis, the main axis perpendicular to the first rotational axis;
- a rotary motor coupled with the master permanent magnet, the rotary motor configured to drive a rotational movement of the master permanent magnet about the first rotational axis;
- and
- a first plurality of slave magnets mounted on a first side of the master permanent magnet along the main axis, each slave permanent magnet of the first plurality of slave permanent magnets magnetized along the main axis, each slave permanent magnet of the first plurality of slave permanent magnets rotatable about a respective rotational axis parallel with the first rotational axis, a distance between each pair of slave permanent magnets of the first plurality of salve permanent magnets consecutively increasing by a predetermined increment along the main axis moving away from the master permanent magnet.
