An apparatus for fitting an earphone device in an ear canal using an anatomically shaped, compressible cushion member with a through channel and a spacer member extending from its side wall, but not connecting to its other side wall, thus providing sufficient acoustic signal transmission to the ear canal in all circumstances by ensuring a 5 minimum clearance C between the opposing side walls of the channel in both a non-compressed state and a compressed state of the cushion member, while also allowing for a flexible and comfortable design.

A converter system comprising a capacitance (C), an inverter () comprising at least two controllable semiconductor switches (S, S, S, S, S, S), and at least two DC conductors () connected between the capacitance (C) and the at least two controllable semiconductor switches (S, S, S, S, S, S), wherein at least one of the at least two DC conductors () comprises carbon fiber.

Converter system having carbon fiber conductor

A method of producing a power electronic assembly and a power electronic assembly including a power electronic module incorporating multiple of semiconductor power electronic switch components, the power electronic module including a base plate with a bottom surface, the power electronic assembly includes further a cooling arrangement for cooling the power electronic module, the cooling arrangement including a cooling surface adapted to be attached against the bottom surface of the base plate of the power electronic module, wherein the power electronic assembly includes further a thermal interface material arranged between the bottom surface of the base plate of the power electronic module and the cooling surface of the cooling arrangement to transfer heat from the power electronic module to the cooling arrangement, the thermal interface material includes a metal foil and a solid lubricant coating.

Power electronic assembly

An explosion vent mounted to seal an opening formed on a wall of a closed space comprises a cover being dimensioned to fit on said opening and having a perimeter with an edge adapted to seal the cover against the opening with a sealing element. A spring element is arranged to hold the cover in the opening and the spring element has a direction of spring action. The cover is held by opposite retaining surfaces in the opening and the cover and he retaining surfaces are acting against the spring action of element. The sealing element is positioned against the opening so that the sealing force is directed at least partially crosswise to the direction of the spring action of the spring element.
