Abstract
An apparatus comprises a movable member, first and second rigid members positioned on opposite sides of the movable member, a first suspension assembly connected between a base and the first and second rigid members, a second suspension assembly connected between the first and second rigid members and the movable member, first and second actuators coupled to the first and second rigid members along a first central axis, and third and fourth actuators coupled to the movable member along a second central axis.
Claims20
An apparatus comprising:
- a movable member;
- first and second rigid members positioned on opposite sides of the movable member;
- a first suspension assembly connected between a base and the first and second rigid members;
- a second suspension assembly connected between the first and second rigid members and the movable member;
- first and second actuators coupled to the first and second rigid members along a first central axis;
- and
- third and fourth actuators connected to first and second protrusions on the movable member along a second central axis.
An apparatus comprising:
- a movable member;
- first and second rigid members positioned on opposite sides of the movable member;
- a first suspension assembly connected between a base and the first and second rigid members;
- a second suspension assembly connected between the first and second rigid members and the movable member;
- first and second actuators coupled to the first and second rigid members along a first central axis;
- and
- third and fourth actuators coupled to the movable member along a second central axis, wherein each of the first and second suspension assemblies includes a plurality of springs each having a first thickness in the first direction and a second thickness in a direction substantially perpendicular to the first direction, wherein the second thickness is larger than the first thickness.
An apparatus comprising:
- a movable member;
- first and second rigid members positioned on opposite sides of the movable member;
- a first suspension assembly connected between a base and the first and second rigid members;
- a second suspension assembly connected between the first and second rigid members and the movable member;
- first and second actuators coupled to the first and second rigid members along a first central axis;
- and
- third and fourth actuators coupled to the movable member along a second central axis;
- wherein the first suspension assembly includes first and second spring assemblies, the second suspension assembly includes third and fourth spring assemblies, each of the third and fourth spring assemblies includes a first spring connected between the movable member and one of the rigid members, and a second spring connected between the movable member and one of the rigid members, and
- wherein each of the first and second springs is a folded spring.
