Abstract:
The invention relates to a device (1) for connecting to a power network (10), said device having a circuit board (2), a first input-side connection point (21), to which a first phase (11) of the power network (10) can be connected, a second input-side connection point (22), to which a second phase (12) of the power network (10) can be connected, and a first and second electrical conductor (3, 4), wherein the first conductor (3) is connected to the first input-side connection point (21) and the second conductor (4) is connected to the second input-side connection point (22) inside the device. In order to provide a device (1) which is as compact as possible and permits as high a short-circuit current as possible, the first conductor (3) is routed as a conductor trace (32) in an interior layer of the circuit board (2) and has a constriction (30) there, the constriction (30) of the first conductor (3) being formed and the second conductor (4) being routed past said constriction (30) in such a manner that electrical insulation existing between the constriction (30) of the first conductor (3) and the second conductor (4) is destroyed in the case of a short-circuit current via the first conductor (3), and therefore an electrically conductive connection between the first and second conductor (3, 4) exists.

Abstract:
A scalable, high-bandwidth connectivity architecture for portable storage devices and memory modules may utilize EHF communication link chip packages mounted in various two-dimensional and three-dimensional configurations on planar surfaces such as printed circuit boards. Multiple electromagnetic communication links between devices distributed on major faces of card-like devices may be provided with respectively aligned pairs of communication units on each device. Adjacent communication units on a printed circuit board may transmit or receive electromagnetic radiation having different polarization, such as linear or elliptical polarization. Power and communication between communication devices may both be provided wirelessly.
Abstract:
A plurality of linear conductors (11) arranged in parallel with each other are covered from the upper and lower sides thereof by first and second insulator layers (12, 13). On the upper side of the first insulator layer (12), a first adjustment material layer (14) is formed with forming a predetermined gap relative to an end of the flat cable (1).
