Abstract: A portable rotary tubing straightener apparatus comprises a mobile console with spool mounting assembly. A motor is supported on the console and drives a shaft which mounts a drive roller. An adjustable tensioner assembly has a tension roller positionable opposite the drive roller. The drive and tension rollers are engageable at opposed locations of a continuous tubing. A rotary straightener assembly is disposed on the console. A motor carried by the console is activatable to rotate the rotary straightener assembly. A spool with metal tubing is mounted to the spool mounting assembly and passes tubing through the rotary assembly and between the rollers. Upon activating the motors, the tubing unwinds from the spool and exits in a continuous straightened condition from the drive and tension rollers. A rotary handle is employed for adjusting the tension in the tension roller.

Abstract: A projector (20) projects a structured light pattern (46) along a first optical axis (44) onto a surface (80). A viewer (50) attached to the projector (20) receives a reflection of the structured light pattern (46) from the surface (80) along a second optical axis (54), and digitizes a two-dimensional snapshot. The optical axes (44, 54) are non-parallel, and they meet within a common field of view of the projector (20) and the viewer (50). A computer (61) interfaced to the viewer (50) receives the digitized snapshot, and analyzes it to mathematically model the surface for display and inspection. The projector and attached viewer are designed as a hand-held unit with a hand grip (66) and a trigger button (68) to trigger a snapshot. A guide tip (70) on the unit extends beside the two optical axes (44, 54) to the common field of view to position the hand-held unit.
