Abstract
An apparatus to control displacement of a body spaced-apart from a surface includes a flexure system having a first flexure member defining a first axis of rotation and a second flexure member defining a second axis of rotation. A body is coupled to the flexure system to move about a plurality of axes. An actuation system is coupled to the flexure system to selectively constrain movement of the body along a subset of the plurality of axes.

16. An apparatus to control displacement of a body spaced-apart from a surface, said apparatus comprising:
-
a flexure system having first flexure and second flexure members;
a body; and
an actuation system coupled to said flexure system with said body being coupled to said flexure system to move with respect to a plurality of axes with said actuation system being configured to selectively constrain movement of said body along a subset of said plurality of axes. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 26)

27. An apparatus to control displacement of a body spaced-apart from a surface, said apparatus comprising:
-
a flexure system;
a body; and
an actuation system coupled to said flexure system with said body being coupled to said flexure system to move with respect to a plurality of axes with said actuation system being configured to selectively constrain translational displacement of said body with respect to a subset of said plurality of axes and to constrain rotational displacement of said body with respect to a subgroup of said plurality of axes. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)

37. An apparatus to control displacement of a body spaced-apart from a surface, said apparatus comprising:
-
a flexure system having first and second flexure members with said first and second flexure members each including a mount, a pair of spaced-apart braces, a first flexure arm pivotally connected between said mount and one of said pair of spaced-apart braces, and a second flexure arm pivotally connected between said mount and one of said pair of spaced-apart braces disposed opposite to said first flexure arm;
a body; and
an actuation system coupled to said flexure system with said body being coupled to said flexure system to move about a plurality of axes with said actuation system being configured to selectively constrain translational displacement of said body with respect to a subset of said plurality of axes and to constrain rotational displacement of said body with respect to a subgroup of said plurality of axes with said subset of axes including two substantially orthogonal axes and said subgroup including an additional axis extending substantially orthogonally to said two substantially orthogonal axes. - View Dependent Claims (38, 39, 40, 41, 42, 43)
