Abstract: A magnetic gear arrangement is provided having a first gear member that generates a first magnetic field and a second gear member that generates a second magnetic field. A plurality of interpoles are disposed between the two gear members for coupling the first and second magnetic fields to control a gear ratio between the gear members. At least one interpole has wiring associated with it that can be activated to alter the magnetic flux at the interpole, so as to vary the coupling between the first and second magnetic fields. The wiring is electrically connected to an electronic filter, which modifies the current passing through the wiring, so as to modify the influence of the wiring on the magnetic flux at the interpole.

Abstract: Apparatus to control transmission of data, the apparatus comprising: a controller configured to: receive data from at least a first sensor within an azimuth thruster; control storage of the received data in memory; determine whether at least one criterion is satisfied, the at least one criterion varying with the relative positioning of a first antenna mounted on a lower housing of the azimuth thruster and a second antenna mounted on an upper housing of the azimuth thruster, the lower housing being configured to rotate relative to the upper housing; and control transmission of the stored data from the first antenna in response to determining that the at least one criterion is satisfied.
