  • Magnetic actuation method
    Patent number: 8779637
    Abstract: The present invention relates to a magnetic actuation method according to which a magnetized mobile (4) is directed by means of at least one magnetic element (2, 2a, 2b) placed opposite said magnetized mobile, characterized in that the preferred direction (or easy axis) of magnetization is made to turn at every point of said element by applying at least one mechanical constraint to said magnetic element(s) (2, 2, 2b), causing anisotropy within said element and thus moving the magnetized mobile in a preferred linear direction or causing the same to rotate.
    Type: Grant
    Filed: October 23, 2009
    Date of Patent: July 15, 2014
    Assignees: Institut Polytechnique de Grenoble, Centre National de la Recherche Scientifique
    Inventors: Daniel O'Brien, Jérôme Delamare, Orphée Cugat, Olivier Geoffroy
  • MAGNETIC ACTUATION METHOD AND DEVICE
    Publication number: 20110248581
    Abstract: The present invention relates to a magnetic actuation method according to which a magnetised mobile (4) is directed by means of at least one magnetic element (2, 2a, 2b) placed opposite said magnetised mobile, characterised in that the preferred direction (or easy axis) of magnetisation is made to turn at every point of said element by applying at least one mechanical constraint to said magnetic element(s) (2, 2, 2b), causing anisotropy within said element and thus moving the magnetised mobile in a preferred linear direction or causing the same to rotate.

  • Device for propelling ships
    Patent number: 4102293
    Abstract: The invention concerns a device for propelling ships comprising at least one surface which freely oscillates within a casing under the action of at least one shaft. The surface includes a main blade actuated by the shaft and a smaller leading blade connected to the main blade while providing a free space between the two blades.
