Abstract: A prosthesis may include a first component, a second component, and a coupling member. The first component may include a first body extending from a first end to a second end, which may define a first opening that extends inwardly toward the first end. The first opening may include a first portion having a first diameter and a second portion having a second diameter. The second component may include a second body extending from a first end to a second end. The second body may define a second opening that extends through the second body. The coupling member may be configured to couple the first component and the second component by compressing the first component and the second component. The coupling member may include a shaft portion and a head portion. The shaft portion may be sized and configured to be received in the first opening and the second opening.

Abstract: A system and method for configuring an electronic device is disclosed. A location identifier module comprising a location identifier is positioned at a location, and the electronic device is positioned at the location. The electronic device is configured based on the location identifier.

Abstract: A method and apparatus for determining an axial relationship by viewing a target with an image inverter and determining the relationship of the optical axis of the image inverter relative to the position of the target by comparing the inverted view against another view. The image inverter can act as level by comparing the inverted image with a direct view of the target, or can measure an angle defined by the first target, the image inverter and a second target offset along a second axis. A mirror associated with the image inverter can provide a reflection of the second target along the reflective axis of the mirror, thus providing a measurement of the angle defined by the intersection of the reflective axis and the optical axis. Each target can comprise a bar, which can divide two contrasting portions to clarify the comparison of the inverted image and the direct or reflected image. The bar can be oriented horizontally or vertically, or at any appropriate orientation to support survey of angles or lines.
