US Patent:

62023160, Mar 20, 2001

Filed:

Apr 14, 1998

Appl. No.:

9/059861

Inventors:

Timothy J. Swift - Gilbert AZ
John M. Hunter - Chandler AZ

International Classification:

G01B 5008

US Classification:

33503

Abstract:

A composite structure for use in a coordinate measuring machine (CMM) includes a metallic material joined to a non-metallic material, wherein each material possesses a coefficient of thermal expansion (CTE) less than or equal to 6. 1. times. 10. sup. -6 cm/cm/. degree. C. The metallic material may be INVAR, an alloy of iron and nickel, and the non-metallic material may be carbon fiber reinforced composite. Also, the metallic material may be in the shape of a space frame with the non-metallic material in the shape of stiffeners adhered to the space frame. The modulus of elasticity of the combined space frame and stiffeners is preferably greater than 140 GPa. The space frame may be a modified I-beam with reinforcing structures and mass-reducing cutouts. The stiffener may be a square tube, wherein one stiffener is adhered to each I-beam flange of the space frame. The stiffeners are ground and lapped to produce bearing tracks of high precision for air bearings to traverse.

A63C 11/16

Abstract:

A fluidic exoskeleton system. The system can include one or more fluidic actuator units that have: a joint; a first and second arm coupled to the joint; an inflatable bellows actuator extending between a first and second plate associated with the joint, the inflatable bellows actuator defining a bellows cavity, the inflatable bellows actuator configured to extend along a length of the bellows actuator when inflated by introducing fluid into the bellows cavity; and one or more constraint ribs extending from the joint and surrounding portions of the bellows actuator along the length of the bellows actuator.
