An electromechanical motor assembly includes a stator, a body to be moved and a stator support. The stator has a plurality of electromechanical actuators for moving the body by repetition of steps ensuring that at least one of the electromechanical actuators is in non-sliding contact with the body at every time. The assembly further includes a force applying arrangement for supplying a normal force (N) between the stator and the stator support by at least one spring arrangement. The spring arrangement has a spring constant in the direction (Z) normal to the surface of the body that is lower than 5% of the ratio between the normal force and the average height uncertainty of the surface of the body. The force applying arrangement includes a lateral fixing plate attached between the stator and the support parallel to the main motion direction (X) and juxtaposed to the surface of the body.

Provision of a normal force to electromechanical motor

The sensor and guide wire assembly having a sensor element is inserted into the patient's body. Acoustic or electromagnetic waves are them emitted from an external source toward the sensor element. The sensor element receives the incident waves and enters into a resonating state. The characteristics of the resonance correspond to the variable or variables to be measured. A transducer is located externally from the patient's body and receives the scattered wave and transmits a resultant signal to an electronic drive and detection unit for signal analysis.

Method and sensor for wireless measurement of physiological variables

A method and a device for assembling an air-craft wing incorporating at least two of the operations drilling, riveting and fitting of anchor nuts ( ), where a robot ( ) is mobile relative to the wing in a plane parallel to the wing and where the robot ( ) is equipped with an arm ( ) designed to accommodate a tool holder ( ), where the tool holder ( ) is primarily equipped with tools for performing a single work operation, whereby the robot is moved so that the robot arm ( ) is positioned at the first work position on the aircraft wing unit, where the robot ( ) carries out the first work operation at the said first work position, where the robot arm ( ) is manoeuvred in the correct order to new work positions on the wing unit within a work area ( ) reachable by the robot arm ( ), and carries out the first work operation at these new work positions.

A sensor and guide wire assembly includes a core wire having a distal end, a proximal end, and a plurality of sections of different cross sections and thereby different flexibilities. At least one of the core wire sections has an enlarged portion with a sensor receptacle therein. The assembly also includes a tube that encloses the core wire over at least a fraction of its length such that the core wire extends out from a distal end of the tube. The tube is configured to enable the sensor and guide wire assembly to be inserted into an artery and to be passed to a measurement site inside a patient's body. The assembly further includes a sensor mounted in the sensor receptacle of the enlarged portion of the core wire. A first coil is arranged to enclose a first portion of the core wire extending out from the distal end of the tube, and the first coil is located nearer to the proximal end of the core wire than the sensor. A second coil is arranged to enclose a second portion of the core wire extending out from the distal end of the tube. The second coil is located nearer to the distal end of the core wire than the sensor.

Sensor and guide wire assembly

The sensor guide wire assembly having a sensor element is inserted into the patient's body. Acoustic or electromagnetic waves are then emitted from an external source toward the senor element. The sensor element receives the incident waves and enters into a resonating state. The characteristics of the resonance correspond to the variable or variables to be measured. A transducer is located externally from the patient's body and receives the scattered wave and transmits a resultant signal to an electronic drive and detection unit for signal analysis.
