The present invention relates to a blister pack device for storing and dispensing a dosage unit, including a container having an opening for receiving a blister pack. Functions that may be implemented by a candidate structured cell are identified. The sensor chips may be arranged such that the pinned layers of the different chips are mutually anti-parallel to each other in order to form a push-pull bridge structure. The optically transparent layer is made of resilient material. An electric machine can be connected positively and operatively to one of the component transmission input shafts andor to the output shaft, or can be connected positively and operatively to one of the component transmission input shafts andor to the main shaft.
