Abstract: An intraocular lens implantation injector has a base body and an elongated actuation element projecting into a base body rear section and movably guided along an actuation axis. Actuation element movement is generated selectively by axial push actuation or by a screw actuation about the axis. The actuation element features an external thread at least on one section. At least one spring arm arranged at the base body has an inner surface thread engagement structure facing the external thread. A switch element, interacting with the spring arm, is rotatably or displaceably arranged on the base body. The switch element interacts with the spring arm via an operative contact. At least one switch element inner surface and/or spring arm outer surface involved in the operative contact is angularly inclined to the axis. Switch element rotation/displacement generates spring arm elastic deformation towards/away from the axis, thereby engaging/disengaging the thread engagement structure.

Actuation element movement is generated selectively by axial push actuation or screw actuation about the axis. The actuation element features an external thread at least on one section. A switch element arranged to the base body is rotatable about or displaceable along the axis. The switch element features a spring arm, having an inner surface thread engagement structure facing the external thread. The base body inner surface forms an operative contact with a spring arm outer surface. The inner and/or outer surface is angularly inclined to the axis, or the inner surface features an inner radius varying circumferentially at least in sections about the axis. Switch element rotation/displacement generates spring arm elastic deformation towards/away from the axis, for selective thread engagement structure engagement.

Abstract: A novel type of dye systems comprises a selection of 10H-indolo[1,2-a]indole compounds (henceforth abbreviated as IO compounds) and (5H,7H)-indolo[1,2-a]quinoline compounds (henceforth abbreviated as IQ compounds) showing a solvatochromic effect and exhibiting strong fluorescence in a variety of materials such as polypropylene, polyethylene, oils, various solvents, emulsions. Also disclosed are various methods how the IO/IQ compounds can be administered, especially how they can be produced and administered in situ from a precursor, responding to external stimuli such as enzyme activity, temperature and so forth. The response of a precursor to external stimuli can also be used to determine the presence or absence of such stimuli.

Abstract: A coupler comprises a first line and a second line in each case with two connectors. The lines run in spatial proximity and are coupled. A first connector of the first line and a first connector of the second line are disposed in spatial proximity. A second connector of the first line and a second connector of the second line are disposed in spatial proximity. A signal does not couple or couples only with a high attenuation from the first connector of the first line to the first connector of the second line. The signal is split, in particular, at the design frequency, into largely identical parts to the second connector of the first line and the second connector of the second line. The first line and the second line in this context are strip conductors.
