Abstract: A socket to interface a lower limb which has undergone amputation and a modular element, includes a proximal portion allowing the lower limb that has undergone amputation to be inserted; a distal portion allowing the modular element to be fastened; an internal deformable layer made of silicone rubber, designed to be in contact with the lower limb that has undergone amputation; an external deformable layer made of silicone rubber; a structure made of rigid material arranged between the internal layer and the external layer, comprising at least two posts, each post extending substantially axially from a base on the distal side towards an end on the proximal side, the ends of the various posts being not linked, so as to separate from or approach each other due to the effect of deformation of the internal layer and of the external layer.

Abstract: An electronic bracelet for displaying an interactive digital content to be projected onto a zone of an arm, includes an emitter of a light beam in a non-visible frequency band forming a light sheet designed to cover a first zone of an arm; a projector projecting an image over a second zone, the first zone substantially overlapping with the second zone; a first detector acquiring an image of the second zone; a computer determining at least one position of at least one interaction point of the light beam by analysing a trace of the image acquired by the first detector.
