Abstract: A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, polycrystalline diamond or cubic boron nitride based materials onto which a hard and wear resistant coating is deposited by physical vapour deposition (PVD). The coating includes at least one layer of a NaCl-structured (TicAlaCrbMed)(CzOyNx) where Me is one or more of the elements Zr, Hf, V, Nb, Ta, Mo, W and/or Si, 0.10<a<0.60, b+d>0.20, c>0.05, 0?d<0.25, 0.75<x<1.05, 0?y<0.25 and 0?z?0.25 with a thickness between 0.5 and 10 ?m. The layer has a columnar mictrostructure with an average columnar width of <1 ?m, a compressive stress level of ?6 GPa<?<?0.5 GPa and a nanohardness >25 GPa.

Abstract: The present invention relates to a solution for determining the location of a mobile communication device in a wireless communication network and for determining a network structure of the wireless communication network using a system of plurality of receivers acquiring radio signals from units in the communication network within a geographical area and triangulating the location of the units. The device may be arranged to trigger a re-establishment of connections between units in order to force communication control signal traffic which can be monitored.

Abstract: A method of producing a digital beamformer signal by a number of antenna modules that are alike and by providing a system that implements the method. This is accomplished by introducing signal processing on each antenna module and by creating an asynchronous serial adding chain through the antenna modules to at least in part calculate the digital beamformer signal. Advantageous embodiments according to the invention perform time and space signal processing multiplexing to calculate additional digital beamformer signals.

Abstract: This invention concerns a method of two-way communication between different nodes arranged at different positions in a vehicle, where information in the form of binary symbols is sent on at least two serial communication busses connecting said nodes. The nodes are separated into at least two groups where communication between nodes belonging to one group is more or less critical for driving the vehicle with respect to communication between the nodes in another group; and said different groups of nodes are connected to different communication busses where one end of each bus is connected to a gateway node. The invention also concerns a local area network and a motor vehicle including such an LAN.
