The present patent application is directed to a communication system 0 comprising a first station 1 with a first narrow beam antenna 31 and a second station 2 comprising a second narrow beam antenna 41, wherein the first and second stations 1, 2 are adapted to establish a first communication path 7a for wireless communication via said first and second narrow beam antennas 31, 41, respectively. It is a disadvantage with such a communication system that communication via said first communication path might be disturbed by randomly appearing obstacles. In consequence, the data transmission rate is reduced. According to the present invention said first and second stations 1, 2 are adapted to automatically establish at least one alternative communication path 7b, 7c for wireless communication via said first and second narrow beam antennas 31, 41, said alternative communication path 7b, 7c being spatially different from said first communication path 7a.

The invention relates to a multiband, multipart circuit arrangement for compensating the attenuation of HF radio signals in the signal paths between a transceiver (g) and an external antenna (a). Saidcircuit arrangement consists of a universal front end module (1) with HF switching means (29, 30) on the antenna side (a) for switching the signal paths on the antenna side, a broadband receive amplifier (31) and at least one splitter that distributes the output signal of the receive amplifier to a plurality of outputs of the front end module, and a universal back end module (2) comprising HF switching means (29', 30') on the device side (g) for switching the signal paths on the device side, which module is coupled to the transceiver via the detector circuit, at least one receive amplifier (32) and at least one combiner which combines the input signals of a plurality of inputs of the back end module. The front end module and the back end module can be combined with different power amplifiers (40) and different frequency and/or bandpass filters (37) and can be differently connected.

A bearing arrangement comprising a first part (1) having a bearing surface (1a), a second part (2) having a surface being made of an electrically conductive material and being arranged in sliding contact with the bearing surface (1a),and means for detecting wear of the bearing surface. The wear detecting means comprise a sensor (3), which is arranged in the first part (1), made at least partly of an electrically conductive material and comprises a first area (3d) and a second area (3e). The first area (3d) is electrically connected to the surface of the second part (2) so that an open electrical circuit is formed when the bearing surface (1a) is intact, and when the bearing surface (1a) wears down to a certain predefined thickness, the second area (3e) comes into electrical con- tact with the surface of the second part (2) closing the electrical circuit. The wear detecting means further comprise means for detecting closing of the electrical circuit. The invention also concerns a method for detecting wear of a bearing surface and use of a bearing arrangement in a turbocharger for an internal combustion engine.
