Abstract: A component carrier includes: i) a first layer stack (comprising at least one first electrically conductive layer structure and/or at least one first electrically insulating layer structure, ii) a component embedded in the first layer stack, where a main surface of the component is essentially flush with an outer main surface of the first layer stack iii) a second layer stack comprising at least one second electrically conductive layer structure and/or at least one second electrically insulating layer structure, and iv) a thermally conductive block embedded in the second layer stack. The layer stacks are connected with each other so that a thermal path from the embedded component via the thermally conductive block up to an exterior surface of the component carrier has a minimum thermal conductivity of at least 7 W/mK, in particular at least 40 W/mK. Further, a method of manufacturing the component carrier is described.

Abstract: A device for determining the condition of railway switches or railway crossings by monitoring the end position of tongue rails (2), said device having a sensor (18) within the area of the theoretical frog point (17) of a frog (8), said sensor giving on occasion of a mechanical collision with the wheel flange or with the running surface of the wheel a signal indicating premature wear within the area of the frog.
