Abstract: A method for the production of a diagnostic device comprising the steps of: obtaining a blank from a plastic material sheet; the blank comprising one or more support bands provided with electrical tracks; providing one or more sensitive elements, in particular detection pads, for each band, being configured to generate signals, in particular pressure signals and being connected to the electrical tracks for the transmission of signals; applying a first electrically conductive coating on the blank in the area of the sensitive elements; creating a main structure from the blank, in particular by rolling the blank, keeping the first electrically conductive coating radially on the inside of the main structure; and creating an auxiliary matrix which wraps the main structure and fills the gaps between the support bands, so as to obtain a tubular body.

Abstract: A motor-vehicle wheel support unit includes a first base body provided with attachments for connection to arms of a motor-vehicle suspension, and a second body for rotatably supporting a wheel hub, which is separate with respect to the first base body and is secured to the first base body in one of two different selectable mounting positions, which correspond to two different vertical positions, with reference to a condition of use, of an axis of the wheel hub with respect to the first base body. In this manner, a height of the vehicle from the ground can be modified by simply mounting said second body on the first body in one or the other of the two mounting positions. In each of the two mounting positions, the second body is rotated by 180° around an axis parallel to the wheel hub axis with respect to the other mounting position.
