Abstract
Various embodiments of an apparatus and method for lifting an imaging head are disclosed.
Claims28
An apparatus comprising:
- a base;
- a mount movably coupled to the base and configured to carry an imaging head;
- and
- an elevator configured to lift the mount and to permit lifting of the mount out of engagement with the elevator, wherein the mount includes a first surface and wherein the elevator includes a second surface beneath the first surface and configured to be lifted while in engagement with the first surface to lift the mount relative to the base;
- and
- a sensor configured to sense the proximity of the first surface and the second surface.

An apparatus comprising:
- a base;
- a mount movably coupled to the base and configured to carry an imaging head;
- an elevator configured to lift the mount and to permit lifting of the mount out of engagement with the elevator, wherein the mount includes a first surface and wherein the elevator includes a second surface beneath the first surface and configured to be lifted while in engagement with the first surface to lift the mount relative to the base;
- a third surface coupled to the base;
- a fourth surface coupled to the mount, wherein the third surface engages the fourth surface to limit movement of the mount relative to the base;
- and
- a dampener operably coupled between the mount and the base and configured to dampen movement of the mount in a first direction to a greater degree than in a second direction.
