Abstract: An aircraft lifting assembly includes a jack, a load cell, and a jack adapter. The jack includes an extendable arm having a distal end portion for exerting a force to lift an object. The distal end portion defines a cavity. The jack adapter couples the extendable arm to the load cell and includes a base portion, a cradle portion, and a projection. The base portion defines a jack arm support surface and a load cell support surface. The jack arm support surface opposes the distal end portion of the extendable arm and the load cell support surface opposes the load cell. The cradle portion extends from the base portion to circumscribe a portion of the load cell to secure the jack adapter to the load cell. The projection extends from the base portion into the cavity to secure the jack adapter to the extendable arm of the jack.

Abstract: An information presentation system and process may create the impression in the mind of a person viewing a real scene that the real scene contains a feature that is not in the real scene at the time the real scene is being viewed by the person. The system may include a display configured to display visual images. The display may have a size that is viewable by a first eye of the person at close range without substantially blocking the view of the second eye of the person. The system may have a hooded magnifier that has an end coupled to the display and another end configured to rest against area around the first eye of the person without substantially blocking the view of the second eye of the person.
