Abstract: A method and mechanism for testing communication links. A transmitter contact, or transmission point, is assigned a unique identifier. During a given test, the transmitter conveys a test pattern to a receiver via a link. Following this test pattern, the transmitter transmits a bit of its unique identifier to the receiver. The receiver receives both the test pattern and the identifier bit, and determines whether the received test pattern matches an expected value. If the test pattern was correctly received by the receiver, the receiver transmits the received identifier bit back to the transmitter. However, if the received test pattern is not correct, the receiver complements the received identifier bit and transmits the complemented bit back to the transmitter. The transmitter receives the identifier bit from the receiver and determines whether it matches the identifier bit which was originally transmitted by the transmitter.

Abstract: At least one power semiconductor component is cooled by a flat, copper, plate-type hollow body conducting a coolant fluid. Components are fixed on one flat-sided surface of the hollow body and the other flat-sided surface includes two coolant fluid openings for introducing the coolant fluid into the hollow body and for evacuating the fluid therefrom. The other flat-sided surface is concave and elastically deformable between the coolant fluid openings. The concave other surface is attached to the even surface of a support in such a way that the concave surface and the even surface are pressed against each other by the elastically planar deformation of the concave surface and that the coolant fluid openings are sealed in a fluidproof manner by O-rings. A solid strut, which interconnects the two flat-sided surfaces is additionally configured in the hollow body. The cooling device may be used in a module or an assembly including a support and the cooling device or module.
