Abstract:
1. An apparatus for providing support between a first structure and a second structure, comprising: a first section having a first group of at least one magnetic frame member, the first section being coupled to the first structure; and a second section having a second group of at least one magnetic frame member, the second section being coupled w the second structure, wherein the first and second sections present magnetic force therebetween, wherein the second group of at least one magnetic frame member is provided within the first group of at least one magnetic frame member, wherein the first group of at least one magnetic frame member has a first direction of magnetic poles, the second group of at least one magnetic frame member has a second direction of magnetic poles, and the first direction is opposite to the second direction, wherein the first section includes a first number of at least one magnetic frame member, the second section includes a second number of at least one magnetic frame member, and a difference between the first number and the second number is no more than 1, and wherein the first number is more than 1, the second number is more than 1, a first pitch of the magnetic frame members included in the first group is smaller than a second pitch of the magnetic frame members included in the second group.
