The invention relates to devices for detecting media. These are distinguished, in particular, by the fact that simply the medium can be detected and/or properties of the or a medium can be determined or monitored. For this purpose, a heating sensor comprising a heating device and at least one p-n junction operated in the forward direction and a reference sensor comprising at least one p-n junction operated in the forward direction are spaced apart from one another. The heating device and the p-n junctions are connected to a control device, which is a control device ascertaining the presence and/or at least one property of the medium from the thermal properties of the medium.

The invention relates to devices for detecting the fill level of media in containers. The devices are distinguished, in particular, by a simple and reliable detection of the fill level. For this purpose, multiple measuring points, each consisting of a series circuit of a resistor and a p-n junction, are spaced apart from one another. Each measuring point is connected, on the one hand, to an input of a multiplexer. On the other hand, the measuring points are connected to a reference potential. The output of the multiplexer is connected to a control device, wherein the control device is

In one example, the disclosure relates to plug connections of conductor tracks of at least two interspaced circuit boards with the aid of at least one plug connector. The plug connections are distinguished, for example, by the fact that the conductor tracks are easily electrically conductively interconnected. For this purpose, the plug connector can be a column having a polygonal or star-shaped or conic-section-shaped cross-section. The column can include at least two C-shaped contact springs positioned opposite each other. Moreover, the interspaced circuit boards each include, at the same point, an opening for partially accommodating the column, including plated through-holes, and so the interspaced plated through-holes of the circuit boards can be electrically conductively interconnected via the contact springs of the column.

To simplify and speed up folding of plate-like elements () along a fold line (), more particularly in a continuous operation, a method and a an apparatus for folding plate-like elements () are proposed which eliminate the use of counter-impression elements in the region of the fold line (). The apparatus includes a second impression device () that folds a second section () of the plate-like element () about the fold line () by a first force component oriented perpendicular to the plane of the second section (). At the same time the second impression device () produces a second force component oriented in the plane of the second section () and acting in the direction of the fold line () to urge a first section () of the plate-like element () against a first impression device ().
