Abstract:
An electronic control device includes a substrate, a plurality of component-mounted wires, a plurality of electronic components, a common wire, an interrupt wire and a protective layer. The component-mounted wires and the common wire are disposed on the substrate. The electronic components are mounted on the respective component-mounted wires and are coupled with the common wire. The interrupt wire is coupled between one component-mounted wire and the common wire, and is configured to melt in accordance with heat generated by an overcurrent to interrupt a coupling between the component-mounted wire and the common wire. The protective layer covers a surface of the substrate including the interrupt wire and defines an opening portion so that at least a portion of the interrupt wire is exposed.

Abstract:
An electronic device is protected from unauthorized access by use of a security wrap having a security screen connected to an alarm circuit of the electronic device. The security screen has a pair of screen terminals interconnected by a conductor. The conductor is formed on a substrate. The substrate is arranged such that attempts to remove the security wrap will result in the substrate being torn and the conductor being damaged or broken whereby the resistance of the conductive path formed by the conductor changes to indicate an alarm condition.

The invention relates to a method for generating an electronic system for application to freeform surfaces, a method for producing freeform surfaces having an electronic system, and an electronic system and a combination of a freeform surface having at least one such system. According to the invention, an elastic interconnect device having an elastic substrate and an elastic, fanned-out contact structure with contact surfaces comprised of conductor lines is generated first. Then, electronic components are mounted on the interconnect device. Finally, the interconnect device is encapsulated. If a freeform surface with an electronic system is to be generated, the electronic system produced in this way is then mounted on the previously provided freeform surface.

Abstract:
A printed circuit includes a hole, a stack, one or more first coils, a magnetic core, and a pad. The hole passes through the vertically through the board to receive a conducting wire. The stack comprises metallization layers vertically stacked and separated mechanically from one another by electrically insulating layers. The first coils fulfill functions of a measurement coil and of an excitation coil. Each first coil has turns wound solely around the magnetic core. The magnetic core forms a first magnetic ring surrounding the hole and extending horizontally between metallization layers. Each turn of each first coil is formed by two conducting tracks produced, respectively, in metallization layers situated above and below the first magnetic ring. The pad passes through an insulating layer and passes through an interior of the magnetic ring, electrically linking the two conducting tracks.

A dielectric element assembly includes a plurality of stacked dielectric sheets. A signal line is provided in or on the dielectric element assembly. A ground conductor is provided in or on the dielectric element assembly on the negative direction side of a z-axis direction relative to the signal line and is arranged so as to oppose the signal line via the dielectric sheets. The ground conductor includes a main body portion and protruding portions. The main body portion extends along the signal line on one side of a direction perpendicular or substantially perpendicular to the signal line relative to the signal line when viewed in plan from the z-axis direction. The protruding portions protrude from the main body portion toward the signal line and overlap the signal line when viewed in plan from the z-axis direction.
