Abstract: The present disclosure relates to medicament injection devices. An injection device includes: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity, a sensor arrangement including a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency, a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency, and a processor arrangement configured to, based on the detected movement, determine a medicament dosage administered by the injection device.

Abstract: A threading tool (1) and method are provided for threading an eye of an eyed article (30). The tool (1) comprises a pair of cooperating elongate hinged members (2, 3) and three locators (8) for the eyed article (30) wherein the elongate hinged members (2, 3) are movable into and out of contact with one another and provide three cooperating passageways (20) for different sized threads when in contact with one another. The passageways (20) extend transversely of a longitudinal axis of the elongate hinged members (2, 3), each passageway (20) has an inlet (21) for a thread, an outlet (22) for the thread, the outlet (22) being smaller than the inlet (21). The locators (8) can position an eye of an eyed article (30) in alignment with the respective outlets so that the thread may be run there through to include through the eyelet. The locators (8) being sized for different sizes of eyelets.
