  • Patent number: 12578684
    Abstract: A device for fluid display comprising a fluid, wherein the fluid is displaced by an electrowetting process. The device is filled with at least 2 immiscible fluids, whereas one fluid is located within the electrical field generated by a reference electrode and a control electrode and partially within the electrical field generated by the same reference electrode and at least one second control electrode so that the electric activation of the second control electrode generates a deformation or movement of the fluid in the direction of the second control electrode. Also provided is a method of switching the control electrodes of the device above-mentioned device in a sequence so that a portion of the fluid is displaced within the device.

  • Publication number: 20250357835
    Abstract: Disclosed is an electric generator device (20) including at least one rotor (22), at least one coil (26), and a magnetic or ferromagnetic bridge (24a, 24b). The rotor has an axis of rotation (22c) with magnetic elements (22b) disposed around said axis of rotation. The magnetic elements define pole pairs to create an alternating magnetic field when rotated around the axis of rotation. The coil is away from a direct influence of the alternating magnetic field. The bridge includes a first and second bridge elements joining the rotor to the coil. The bridge elements include teeth (24c) around the magnetic elements so that a voltage within the coil is induced due to the alternating magnetic field within the bridge caused by the rotation of the magnetic elements. The teeth are interdigitated between both bridge halves and their total number correspond to double the number of pole pairs of the magnetic elements.
