A device for dosing a substance, including at least one rotating element and at least one coding element associated with the rotating element, using which the rotational position of the rotating element can be identified, further including at least one reference element whereby a reference signal is generated at pre-set positions or changes in position, and a method for identifying the rotational position of a rotating element which serves to set a dose, wherein the rotational position of the rotating element is identified by a coding which is only read or evaluated when a reference signal is generated at pre-set rotational positions or positional transitions.

Device and method for dosing a substance

An ampoule for use with an administering device such as an injection or infusion apparatus, at least two recognition elements associated with the ampoule, each of which at least two recognition elements can be arranged in one of at least two predetermined positions relative to the ampoule, wherein the at least two predetermined positions are asymmetrically located relative to the ampoule, and an administering device such as an injection or infusion apparatus which can be coupled to the ampoule. In one embodiment, the administering device has at least two associated sensors at predetermined positions in order to recognize the arrangement of the at least two recognition elements associated with an ampoule and, in another embodiment, the administering device has at least one sensor which can be moved relative to an ampoule.

Ampoule recognition

The invention relates to a device for detecting the position of a rotor relative to a stator, wherein at least one electrode is arranged on the rotor and at least one electrode is arranged on the stator, such that the electrodes at least partially overlap in at least one rotational position of the rotor relative to the stator, and encompasses a method for measuring the rotational position of a rotor including at least one rotor electrode relative to a stator including at least one stator electrode, wherein the rotational position is detected using a capacitive coupling between the rotor electrode and the stator electrode.
