Abstract: A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and are connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and are electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, are in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.

Abstract: Medical appliance (9, 9a, 9b, 9c) for a joint (1) of a person (10), which has at least two parts (11) which are to be placed on the joint (1) and can be moved with respect to one another by the joint (1) and at least one detection device (13) for detecting a relative movement of the parts (11), wherein the medical appliance (9, 9a, 9b, 9c) comprises an evaluation device (16), having: a determination unit (17) for determining, from detection data of the detection device (13), a range of movement (5) of the joint (1), which range of movement is actually used when the medical appliance (9, 9a, 9b, 9c) is worn, a comparison unit (18) for comparing the range of movement (5) used with a desired range of movement (6), and a support unit (19) for determining support information guiding the person (10) to the most extensive use possible of the desired range of movement (6), said support information being dependent on the result of the comparison.
