Abstract: A coupling system includes two base bodies, each having an aperture for a fluid, an interior predefined circumferential depression and a locking surface. An adapter piece including an aperture for the fluid has two ends and at least two predefined circumferential depressions, which run at least partially along a circumference of the respective ends, wherein the first base body is associated with the first end of the adapter piece and the second base body is associated with the second end of the adapter piece, wherein in a state in which they are pushed inside each other the circumferential depression associated with the respective end of the adapter piece and the interior circumferential depression of the respective base body are located opposite of each other and form a receiving space. In addition, latching elements are provided to prevent the respective latching element from accidentally sliding out of the associated receiving space.

Abstract: The invention relates to a coupling system comprising two base bodies, each of which has an aperture for a fluid, an interior predefined circumferential depression and a locking surface (26). An adapter piece (1) comprising an aperture (9) for the fluid has two ends (2, 3) and at least two predefined circumferential depressions (4), which run at least partially along a circumference of the respective ends, wherein the first base body (21) is associated with the first end (2) of the adapter piece (1) and the second base body (21) is associated with the second end (3) of the adapter piece (1), wherein in a state in which they are pushed inside each other the circumferential depression (4, 5) associated with the respective end (2, 3) of the adapter piece (1) and the interior circumferential depression of the respective base body (21) are located opposite of each other and form a receiving space (22).

Abstract: A tracer system for analyzing errors of programs in running real-time systems. An activation device effects execution of predetermined functions at predetermined program points that are trace points. An executive device control operational sequence of a tracing process and instigates an immediate continuation of a attested program after execution of the functions at a trace point. An input for inputting trace points into the real-time system and for inputting associated functions during execution of the real-time system. A generating device for generating during program execution trace routines for execution of the predetermined functions and also for assigning memory areas for receiving data determined by the trace routines.
