Abstract: A lens tinted and/or shaded according to a particular and predefined shape having at least first and second colour zones and/or a third shaded zone according to a gradient of transition from the first to the second colours, the second colour zone and/or third shaded zone according to a gradient obtained by subjecting a colour lens to a process having the following steps: positioning lenses on at least one frame, arranging the frame above a colouring tank or bath, the frame being vertically movable along first and second vertical axes z1, z2, respectively, the z1 stroke being greater than that of z2, the frame being rotatable about an axis of rotation, perpendicular to axes z1 and z2, and parallel to the free surface of the bath; the shape on the lens obtained by a combination of movement according to axis z1, axis z2, and/or rotary axis or rotation direction.

Abstract: The present invention relates to a system (1000) for cleaning and/or disinfecting a tool (600) for dental or surgical use, comprising a steam generator (100) and a compressed air source (200), the cleaning and/or disinfecting system (1000) further comprising a flow regulating device (400) designed to inject wet steam (1) and compressed air (2) into at least one channel of the tool (600) for dental or surgical use that is to be treated.

Abstract: Portable human-machine interface device intended to be removably connected to a controller (2) of at least one surgical or dental instrument (4), the controller (2) being installed in a power and control unit (6) or a table top equipment (8), the interface device (1) including hardware and software means allowing a user to enter an instruction or data into the interface device (1) to control, via the controller (2), the operation of the surgical or dental instrument (4).
