Title: (EN) Contact free absolute position determination of a moving element in a medication delivery device
(ZH) 药物输送设备内的移动元件的自由接触的绝对位置确定
Abstract: front page image
(EN) The present invention relates to a medication delivery device for expelling set doses of medicament, the medication delivery device comprising a position determining assembly for detecting absolute positions of a rotatably mounted member arranged within the device, the position determining assembly comprising a plurality of transmitter electrodes arranged on a first exterior surface part of the rotatably mounted member, a plurality of receiver electrodes arranged on a second exterior surface part of the rotatably mounted member. A number of transmitter electrodes form pairs of interconnected electrodes with a number of receiver electrodes. A reading assembly fixedly arranged relative to for example the housing of the medication delivery device is also provided. The reading assembly comprises a plurality of transmitters arranged to electrically couple to one or more receiver electrodes, the reading assembly further comprising a plurality of receivers arranged to electrically couple to one or more transmitter electrodes.
