Abstract
Abstract A folded remote center compliance device including first and second structures serially connected between a mounting member and an operator member for enabling translational motion and rotational motion of the operator member about a remote center at, near, or beyond the end of the operator member; one of the structures including at least two stages connected in series, each stage including flexure means disposed along radii of a focus, the first of the stages being connected with the other of the structures and a second of the stages being connected with one of the members, the other of the members being connected with the other of the structures, and an intermediate section for interconnecting flexure means in adjacent stages.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
A folded remote center compliance device including first and second structures serially connected between a mounting member and an operator member for enabling translational motion and rotational motion of said operator member about a remote center at, near or beyond the end of said operator member; one of said structures including at least two stages connected in series, each stage including flexure means disposed along radii from a focus, a first of said stages being connected with the other of said structures and a second of said stages being connected with one of said members, the other of said members being connected with the other of said structures, and an intermediate section for interconnecting flexure means in adjacent stages.
Claim 2
Dependent Claim
119 words
A folded remote center compliance device including first and second structures serially connected between a mounting member and an operator member for enabling translational motion and rotational motion of said operator member about a remote center at, near or beyond the end of said operator member; one of said structures including at least two stages connected in series, each stage including flexure means disposed along radii from a focus, a first of said stages being connected with the other of said structures and a second of said stages being connected with one of said members, the other of said members being connected with the other of said structures, and an intermediate section for interconnecting flexure means in adjacent stages.
Claim 3
Dependent Claim
20 words
The device of claim 1 in which said flexure means in each stage includes at least three discrete flexure elements.
Claim 4
Dependent Claim
16 words
The device of claim 1 in which said flexure means in each stage is flexible throughout.
Claim 5
Dependent Claim
18 words
The device of claim 1 in which said flexure means in each stage is flexible at specific portions.
Claim 6
Dependent Claim
21 words
The device of claim 1 in which said flexure means in each stage is disposed along radii from the same focus.
Claim 7
Dependent Claim
20 words
The device of claim 1 in which said flexure means in each stage is disposed along radii from different foci.
Claim 8
Dependent Claim
15 words
The device of claim 5 in which said focus is coincident with said remote center.
Claim 9
Dependent Claim
17 words
The device of claim 6 in which one of said foci is coincident with said remote center.
Claim 10
Dependent Claim
33 words
The device of claim 1 in which said stages are formed of a pleated member in which one part of each pleat includes a flexure means and the other part an intermediate section.
