Abstract: The present invention relates to an injection device comprising an optically-based sensor for determining the position or setting of a dose setting member arranged to set a dose to be injected from the injection device. In particular, the present invention relates to an injection device comprising a rotatably mounted member having a plurality of optically coded paths arranged on an outer surface thereof. The rotatably mounted member is operatively connected to the dose setting member and is adapted to rotate with the dose setting member.

Abstract: The present Invention relates to an injection device capable of emitting a flashing light signal indicating the time elapsed since last ejection and/or the size of the last ejected dosage and/or a return signal indicating the operable state of the device and/or a time out signal indicating when the pen can be removed after ejecting of a dosage. The injection device comprises an electronic control circuit comprising: a sensor unit arranged to detect the occurrence of an ejection of a drug from the injection device; a timer for determining an approximate time elapsed since last ejection; a signal emitting device being able to emit a signal, the signal emitting device being controllable by the electric control circuit, so as to emit a time signal that varies with the time elapsed since last ejection.

Abstract: The present invention relates to a medication delivery device for expelling set doses of medicament, the medication delivery device comprising a position determining arrangement for detecting absolute positions of a movably mounted member, such as a dose indicator barrel, relative to a housing of the medication delivery device. The position determining arrangement comprises a plurality of electrically conducting electrodes arranged on an outer surface of the movably mounted member, and a plurality of contacts members fixedly arranged relative to the housing of the medication delivery device. A first and a second contact member are arranged to follow a first path across the electrically conducting electrodes upon movement of the movably mounted member relative to the housing, whereas a third and a fourth contact member are arranged to follow a second path across the electrically conducting electrodes upon movement of the movably mounted member relative to the housing.
