Abstract: A new titanium-based implant is disclosed, which is formed by a titanium coating manufactured with biomaterials with applications in osseous implantology. The nanotopographical characteristics of these implants inhibit bacterial adhesion and the formation of a bacterial biofilm on the surface, whilst simultaneously presenting suitable properties for the adhesion, stretching and proliferation of bone-forming cells. Moreover, the invention comprises a method for manufacturing the implant by means of oblique-incidence techniques and the use thereof in osseous implantology.

Abstract: The invention relates to a contactor-circuit breaker device (2, 102, 202), comprising: a switch (4) including two pairs of contacts (10, 12) each comprising a stationary contact (14, 16) and a moving contact (18, 20), the stationary contacts (14, 16) being connected in series to an electrical circuit (22), the switch (4) being capable of switching between a closed configuration of the electrical circuit (22) and an open configuration of the electrical circuit (22); a support member (24) for the moving contacts; a current cutoff module (6) able to switch the current from the electrical circuit (22) to the cutoff module (6); and a movement apparatus (26) for moving the support member (24) comprising a armature (44) capable of translating the armature such that the support member switches between the closed configuration and the open configuration through a translational and/or rotational movement.

Abstract: This device protects at least one electronic switching branch of an electrical conversion system against an overcurrent, each branch comprising two switching half-branches serially connected at an intermediate terminal, at least one half-branch including a switching member, each switching member comprising a first controllable switch and a diode connected in antiparallel to the first switch. The protection device includes, for each switching branch, at least one second controllable switch, each second switch being connected to the intermediate terminal or to an electrode of said diode in antiparallel to the first switch, each second switch being able to switch, under action of a controller, from an on state to an off state to protect said diode from the overcurrent, means for measuring a magnitude relative to a current able to circulate in each diode, and means for controlling each second switch, based on the measured magnitude.
