Abstract: An actuator position sensing system for sensing a position of an actuator. The actuator position sensing system includes a first sensor for detecting a position of a first moveable portion of the actuator; a plurality of second sensors each being configured for detecting a position of a second moveable portion of the actuator; and a controller connected to the first sensor and the plurality of second sensors. The controller is configured to calculate a difference between (i) a position of the second movable portion as calculated based upon the data transmitted from the first sensor, and (ii) a position of the second movable portion as calculated based upon the data transmitted from one or more of the plurality of second sensors. A motor is connected to the first movable portion and the controller, and the motor is configured to move the first moveable portion based upon the calculated difference.

Abstract: The invention relates to a dose control system configured for an injectable drug delivery device. The device comprises a disk-shaped diametral single-dipole magnet (9) attachable to a rotatable dose wheel, a housing removably attachable to the proximal extremity of the drug delivery body and comprising at least a first and a second magnetic field measurement means (8). An integrated control unit (2) is connected to the magnetic field measurement means and is configured to process information received therefrom. The magnetic field measurement means are located in the housing in a displaced axial relationship relative to the longitudinal axis of the drug delivery body and the magnet. The magnet is configured to co-rotate with the dose setting wheel and the integrated control unit is configured to provide a normalized vector with regard to the displaced axial relationship of the magnetic field measurement means, said normalized vector being derived from the measured magnetic field generated by the rotation of the magnet and measured by the magnetic field measurement means. A dose setting is calculated from said normalized vector.
