Abstract: A drug delivery device (1) includes a delivery unit, an electronic control system and a plunger sensing system (70). The delivery unit (3) includes a drug container (6) comprising a barrel portion (6a) and a plunger (12) slidably mounted within the barrel portion and sealing against an inner surface of the barrel portion (6a) for containing a liquid drug (78) within the drug container. The plunger sensing system (70) includes an optical sensor (71) with a transmitter (71a) and a receiver (71b), the transmitter configured for transmitting an optical signal to a back end (73) of the plunger (12) and the receiver configured to receive the optical signal reflected off the plunger back end (73). The plunger sensing system is connected to the electronic control system (47) configured to measure a time of flight of the optical signal from the transmitter to the receiver and to determine therefrom a position of the plunger within the cylinder portion of the drug container.

Abstract: A drug delivery device (1) comprising a housing (2), a delivery unit (3) including a drug container (6), and a control unit (4) mounted within the housing (2), the control unit comprising an on-body sensing system (5) including an electrode (56) connected to an electronic control system (47) of the control unit for measuring a capacitance value configured to detect whether the drug delivery device is positioned against a patient's skin, a skin contact wall (81) of the housing (2) having an inner side facing an inside of the housing in which the delivery unit and control unit are mounted, and an outer mounting side facing the outside of the housing and intended to be placed against the skin of a patient. The electrode (56) comprises a layer of metal mounted directly against the inner side of the skin contact wall.

Abstract: The present invention relates to a method for testing the accuracy of the automatic positioning means of a signal tracking antenna during a satellite signal searching and/or tracking operation; wherein the platform, such as a ship, on which the signal tracking antenna is mounted is kept stationary during the testing operation. The method includes the use of an unmanned aerial vehicle and a control station.
