Abstract:
The invention relates to a device for analysing the physico-chemical properties of a cutaneous surface comprising: a group of sensors which are assembled at an acquisition zone (4), opposite which the cutaneous surface to be analysed is positioned; and a processing unit (1) which is interfaced with the group of sensors, said unit being equipped with analysis means that can be used to determine certain physico-chemical properties of the cutaneous surface to be analysed using signals produced by said group of sensors.
Abstract:
Device allowing the end (4) of an optical fiber (3) to be positioned and held in place inside a substrate (1), wherein: the substrate (1) has a groove (2) intended to accommodate the end (4) of the optical fiber (3), said groove (2) possessing at least one plane wall (8) perpendicular to the principal plane (9) of the substrate (1); the groove (2) includes a moveable part (5), located on the face opposite the plane wall (8) and capable of moving toward said plane wall (8) between two positions, namely; a retracted position in which the end of the optical fiber (3) can penetrate freely into the groove (2); a locked position in which the moveable part (5) comes into contact with the optical fiber (3) in order to press it against said plane wall (8); it includes means (21, 24) allowing a force to be exerted on the moveable part (5) in order to cause it to move with respect to the plane wall (8)
Abstract:
An inductive component (1), especially intended to be incorporated into a radiofrequency circuit, comprising: a substrate layer (2); a flat inductor formed from a metal strip (3) wound in a spiral; wherein: the substrate layer (2) is made of quartz; the metal strip (3) is made of copper and has a thickness (E3) of greater than 10 microns.
Abstract:
A monolithic integrated circuit (1) incorporating an inductive component (2) and comprising: a semiconductor substrate layer (2); a passivation layer (4) covering the substrate layer (2); metal contact pads (5) connected to the substrate (2) and passing through the passivation layer (4) in order to be flush with the upper face (6) of the passivation layer (4); which circuit also includes a spiral winding (20) which forms an inductor and lies in a plane parallel to the upper face (6) of the passivation layer (4), said winding (20) consisting of copper turns (21-23, 27, 28) having a thickness of greater than 10 microns, the winding ends forming extensions (12) which extend below the plane of the winding (20) and are connected to the contact pads (5).
