Abstract: The present invention relates to a wireless data communication module (100) for a drug injection device. The wireless data communication module (100) comprises a folded flexible carrier member (107) comprising a plurality of stacked component support regions (203, 205, 207, 209, 211) and a display (103), such as a LCD or OLED display, electrically connected to a first component support region (203) of the folded flexible carrier member (107) via a first set of electrical connection terminals. The display (103) comprises an outwardly facing readable display and an opposing, downwardly facing, optical reflector (319). The wireless data communication module (100) additionally comprises a NFC antenna (105) attached to a second component support region (205) of the folded flexible carrier member (107) situated below the first component mounting region (203). The optical reflector (319) of the display comprises an optically reflective and non-magnetically permeable material.

Abstract: A cleaning process and apparatus for cleaning small diameter clogged holes or passages fashioned as deep through-holes or small diameter through-holes of varying sizes. The holes may be provided in dies for enabling a pressing of materials for manufacturing of pellets such as feed stuff pellets. The cleaning is effected by directing at least one water jet having a diameter less than one-half of a smallest diameter of the hole or passage to be cleaned. The cleaning medium is supplied possibly at supersonic speed. It is also possible to clean radially oriented holes or passages in the die by ejecting the cleaning medium from nozzles of the apparatus.
