Patent ID: 7902725

Claim:
A device for fixing a first piece of equipment (E 1 ) relative to a second piece of equipment (E 2 ), comprising: (i) a structure comprising a rigid central body (CC) and two approximately identical terminal bodies (CTi), prolonging two opposite ends of said central body (CC), and each comprising a neck defining a flexible intermediate part (PDi) that is symmetric relative to a symmetry element, having a first extension relative to this symmetry element, situated in a central position and prolonged by a rigid internal part (PIi) that is symmetric relative to said symmetry element, having a second extension relative to said symmetry element greater than the first and joined to one of said ends of the central body (CC), and by a rigid external part (PEi) that is symmetric relative to said symmetry element, having a third extension relative to said symmetry element greater than the first, spaced from said internal part (PIi) and intended to be joined to said first (E 1 ) or second (E 2 ) piece of equipment; (ii) at least two piezoelectric transducers (Tij) respectively housed in free spaces (Si) defined between the internal (PIi) and external (PEi) parts of the two terminal bodies (CTi) and each set up to convert either an axial dimensional change into a measurement current representing the amplitude of said change, or a control current into a corresponding axial dimensional change; and (iii) control means (MC) set up to determine at least one axial dimensional change for at least one of said transducers (Tij) so as to locate said first piece of equipment (E 1 ) in a chosen position relative to said second piece of equipment (E 2 ).
