Abstract: The invention concerns a device (1) for the chromatic confocal measurement of a local height and/or orientation of a surface (S) of a sample comprising—a light source (2) configured to generate a polychromatic light beam (9)—a projection lens (4) comprising a lens (4) with axial chromatism configured to apply the light beam (9) to the surface (S) of the sample, —an optical sensor, configured to receive a light beam (9) reflected by the surface (S) of the sample and measure a total energy of the reflected light beam (9) received during an integration interval, —a scanning system (10), coupled to the projection lens (4) and configured to move the propagation axis of the light beam (9) relative to the projection lens (4), such that the total energy measured by the optical sensor corresponds to a dynamic spatial average of the total energy of the light beam (9) reflected by the surface (S) of the sample.

Abstract: The present invention relates to a device mounted on a wheel set that comprises: a rocker beam 14 connected firstly to a tiltable frame 10 by means of a shock absorber 17 and secondly to two oscillating arms 7, 8 via two connecting rods 13, 15; and blocking means 27 having a first anchor point on said rocker beam 14. Furthermore, the device comprises decoupling means constituted by a horizontal lever 21 and a vertical lever 22 that are connected together by a connection point 24 about which they are capable of pivoting, the free ends of said levers being connected respectively to said frame and to said rocker beam, the second anchor point of said blocking means 27 being on said decoupling means. The invention also provides a vehicle, in particular a quadricycle, provided with the device.

Abstract: The invention relates to a device that comprises: a box 100; a tilting frame 200; and a passive joint 300 that enables tilting of the frame relative to the box; and joint locking means 400. The device further comprises: an accelerometer (500) for measuring the transverse acceleration to which said tilting frame (200) is subjected; and a control circuit for activating the locking means if the transverse acceleration exceeds a predetermined threshold. The invention also relates to a vehicle, in particular a tricycle, provided with said device.
