Patent ID: 8409202

Claim:
A device comprising: a control element; a drive element coupled to the control element; wherein the control element is operable to rotate the drive element about a first axis, and wherein the control element is further operable to angularly reposition the drive element between at least a first position and a second position about a second axis that is substantially orthogonal to the first axis; a housing that supports the drive element, wherein the housing is configured to prevent translational movement of the drive element; and a driven article coupled to the drive element such that when the drive element is in the first position, rotation of the drive element causes the driven article to move translationally in a first direction, and when the drive element is in the second position, rotation of the drive element causes the driven article to move translationally in a second direction, wherein the driven article comprises a socket member having a contact surface coupled to the drive element, and the socket member and the housing are rotatably joined.
