Abstract: A positioning method, as well as the system of base stations (T1,T2,T3) and detector (I) is based on measuring the propagation time difference of externally controlled electromagnetic pulses (F1,F2,F3) and the arrival signals of the controlled base station during a measurement cycle (t1+t2). In one embodiment, a reference clock is not required for measuring propagation time differences, but instead, accurate fixed distances between base stations can be used as a reference. System calibration is rarely performed. It checks the mutual locations of base stations. This may be partially automated. The positioning system does not require any sensors.

Abstract: A connection base is presented connecting current supply cables (1) of an electric motor to phase leads (2) of electric motor windings. The connection base comprises, a body (3) made of an insulating material and terminals (4) coupled thereto, the terminals being arranged to comprise at least one angle (?) and at least a first projection (41) and a second projection (42) on the opposite sides of the angle. The body is provided with first reception means (21) for receiving at least the first projection of the terminal and for keeping it in connection with the body. Furthermore the body is provided with second reception means (14, 15) for receiving a fastening means (12, 13) to be arranged at the first projection and for locking to the body. The fastening means being arranged to lock the terminal to the body and to fasten the phase lead to the terminal.
