Abstract: A harness for the wearing of at least one stage prop by a stage performer includes a frame with a backrest suitable for supporting the stage prop, and elements forming shoulder supports suitable for positioning and/or maintaining the harness in place on the artist's shoulders. The backrest and the elements forming the shoulder supports are rigid. The elements forming the shoulder supports are coupled to the backrest by a pair of elastic coupling elements.

Abstract: In order to change from antero-posterior examination to lateral examination with an osteodensimeter, the yoke carrying the X-ray tube and the radiation detector of this apparatus is moved laterally. Changeover of the entire assembly is enabled when this lateral translation comes into abutment. When changeover is complete, the return transverse translation is performed. Prior to performing lateral examination, the bed on which the patient to be examined is lying is itself raised. It is shown that this dynamic configuration makes it possible to keep the position of the X-ray tube relative to the detector fixed and as adjusted by construction.
