A system and method for redundantly monitoring faultless functioning of first and second rotational speed sensors on an electric motor, where the rotational speed is to precisely determine and monitor a rotor position, where a first product is formed from a first current count of the first output signal of the first sensor and a maximum count of the second output signal, a second product is formed from a second current count of the second output signal of the second sensor and a maximum count of the first output signal, the two products are cyclically checked for equality and, in when the check is negative, an error message is generated, where the method provides the position of both sensors in a common values system and the positions can be directly compared with one another such that precise determination and monitoring of the rotor position becomes possible.

A ball joint is disclosed containing a body of a joint, where there is inserted a pin having a longitudinal axis and including a first threaded end and a second spherical end which is rotatably arranged within a seat of the body and able to co-operate with a first spherical-cap-shaped element or shell inserted within a seat having a corresponding shape of a second spherical-cap-shaped element or shell cooperating with a covering element so as to close the spherical end of the pin within the body. The second spherical end of the pin and the first and second shells including pairs of recesses and ridges in the contact areas are suitable for reciprocally compenetrating, with the pairs of recesses and ridges being arranged at 90° to each other to allow the rotation of the pin along all axes in the space (X, Y, Z). An angular movement sensor integral with the body of the joint is provided, for co-operating with the second element or shell to detect the rotation of the pin around the axis containing the longitudinal axis of the pin.

Inductive position sensors for sensing relative position (e.g., relative rotary position) between members are provided. In one example implementation, the inductive position sensor includes a transmit aerial having at least one transmit winding. The inductive position sensor can include a receive aerial having one or more receive windings. The inductive position sensor can include a coupling element operable to be disposed on the second member. The inductive position sensor can include processing circuitry configured to provide one or more signals indicative of the position of the first member relative to the second member based on current induced in the one or more receive windings resulting from an oscillating signal provided to the transmit winding. The inductive position sensor includes at least one electrostatic shield. The electrostatic shield can include a plurality of conductive traces arranged so that no current loops are formed in the electrostatic shield.

The accuracy of an impedance tuner may be improved and the size may be reduced by using linear actuators instead of rotary motors. The linear actuator may be integrated with position sensors to allow very small size, and implemented with a servo system for best accuracy and speed. Spring loaded arms holding the mismatch probes allow the tuner to operate in any orientation to further fit into small spaces. The small size reduces losses by allowing direct connection to wafer probes for on-wafer measurement systems.
