Abstract: The present disclosure relates to a lamella arrangement, for a cover assembly for a head-up display, and to a method for manufacturing such a lamella arrangement. The disclosure also relates to a cover assembly having such a lamella arrangement and to a head-up display, in particular a head-up display for a transport which has such a cover assembly. The lamella arrangement has a first rack having a plurality of teeth and a first cover rack strip arranged on the first rack and having a plurality of teeth. The lamella arrangement also has a second rack having a plurality of teeth and a second cover rack strip arranged on the second rack and having a plurality of teeth. A plurality of lamellae are fastened between the teeth of the first and second racks and the first and second cover rack strips.

Abstract: Needle insertion mechanisms for an injection device include a housing, a needle holder holding a needle, a slider moveable from a first position retaining the needle holder in a retracted position towards a second position allowing movement of the needle holder to an inserted position. An intermediate member positioned between the needle holder and the slider is moveable from a blocked position to a release position releasing the needle holder for movement to the inserted position. A biased gearing between the intermediate member and the needle holder biases the intermediate member towards the release position. A lock between the intermediate member and the slider is configured to lock the intermediate member in the blocked position against the bias of the gearing. Movement of the slider towards the second position unlocks the lock and the biased gearing moves the intermediate member into the release position thereby releasing the needle holder.

Abstract: An apparatus for generating a virtual image including a display element for generating an image, an optical waveguide for expanding an exit pupil, and an antiglare element, which is arranged after the optical waveguide in the beam path and is configured as a shutter comprising slats, wherein the slats are braced in pre-tensioning equipment outside of a visible region of the apparatus, and rest against a contacting element under pretension.

Abstract: An apparatus for generating a virtual image having a display element for generating an image, an optical waveguide for expanding an exit pupil, and an anti-glare element arranged downstream of the optical waveguide in the beam path, wherein the anti-glare element is a shutter that has a plurality of slats which, in their end regions, have flat reinforcing elements which protrude beyond the slats is disclosed.

Abstract: Needle insertion mechanisms include a housing and a needle holder, the needle holder being linearly guided by the housing to be moved along the needle-axis. A slider linearly guided by the housing and transversally moveable with respect to the needle-axis from a first to a second slider position. The needle holder is operatively coupled to the slider when the slider is in the first position, thereby retaining the needle holder in a retracted position against the bias of a spring acting on the needle holder. In the second position the slider is decoupled from the needle holder and the holder is moved into an inserted position by the spring. A blocking member arranged between the slider and the housing blocking movement of the slider into the second position, is moved by an active drive thereby unblocking the movement of the slider and subsequently moving the slider to the second position.

Abstract: A combination instrument has a disk that is transparent for light in the visible range and that has a dial region and an indicator region. It further has a dial imprint, which is applied to the back of the transparent disk in the dial region. In addition, a polarizing filter disk is provided, which is disposed on the back of the transparent disk aligned with the indicator region and comprises a circular polarizing filter. An optical indicator unit is provided, which is disposed in alignment with the indicator region on the back of the transparent disk and the polarizing filter disk.

Abstract: In an indicating instrument (1) with a translucent dial (8), an illuminated pointer (4) is arranged, out of the viewing direction of a viewer, behind the dial (8) on its rear, inner side (7). The surface of the outer side and/or of the inner side of the dial is reflection-reducing so as to enable the dial to serve the function of a covering glass.

Abstract: In an indicating instrument (1) with a translucent dial (8), an illuminated pointer (4) is arranged, out of the viewing direction of a viewer, behind the dial (8) on its rear, inner side (7). An additional covering glass for protecting the pointer (4) can thus be dispensed with.
