  • Patent number: 11400604
    Abstract: A vacuum gripper device including at least one suction cup including a fastener body from which there extends an elastically deformable skirt having a free annular edge for coming into contact with an object to be grasped. The suction cup includes at least one electrically conductive track secured at least to the skirt. The conductive track is made of a material that is electrically conductive and elastically deformable so as to deform together with the skirt. The device includes an electronic processor circuit that is connected electrically to two connection pads belonging to the conductive track and that is arranged to monitor an electrical property of the conductive track, which electrical property varies with the deformation of the conductive track, and to compare that property with reference data so as to anticipate a failure of the suction cup.

  • Patent number: 9421303
    Abstract: Applicants have disclosed a process for fusing a biocompatible glass to a metal substrate. In the preferred embodiment, the process comprises: grit blasting a metallic substrate (e.g., titanium) to remove a surface layer of the metal; after blasting, cleaning the abrasion residue off the surface layer; blending a solvent to use as a suspension agent; creating a suspension of biocompatible and bioactive glass-coating powders in the solvent solution; depositing the suspension onto the metallic substrate; drying thoroughly the suspension-coated metallic substrate; inserting the dried, coated substrate into a non-reactive chamber, purging the chamber with an inert gas, such as pure argon; and firing the metallic substrate, inside the furnace, in the inert gas. This process forms a robust fusion between the biocompatible glass and titanium, according to preliminary test results. This process can be used for various medical and dental devices, including implants and onplants.
