Abstract: A sensor for real time monitoring the quality of welding joints in the plastic film at the production of plastic bags on roll by measuring material changes in the welding joint is provided. The sensor comprises at least two electrode pairs arranged to measure changes in the dielectric properties of the material when the welding joint is passing through the measuring gap of the electrodes and provide a measuring signal proportional to the material change in the welding joint. The measuring signal is evaluated to detect defective welding joints in the plastic film. The electrodes are arranged so that one pair of the electrodes constitutes the signal measuring gap arranged for measuring the welding profile. The form of the measuring electrode conforms to the direction and form of the welding joint. The other pair of electrodes constitutes the reference measuring gap arranged to provide an averaged signal across the surface of the plastic film.

Abstract: The present invention relates to a model based positioning system that includes a positioning device having at least one transmitter configured to be in a tracking environment, e.g. inserted into a body, a receiver having a plurality of receiver elements arranged outside the tracking environment, a control unit configured to measure amplitude and/or phase information of a signal transmitted from the at least one transmitter and received at each receiving element, and a memory unit for storing a model for each receiving element. The control unit is also configured to estimate the position P of the positioning device by comparing the model for each receiving element with the measured received signal for each receiving element.

Abstract: A method for producing at least one three-dimensional body. Conditions for sensing at least one model are preset. The conditions includes at least an angle of at least one sensor with respect to a longitudinal axis of the model and a relationship between a rotation speed of the model and a speed of movement of the sensor and the model relative to each other in a direction parallel to the longitudinal axis of the model. The model is rotated while simultaneously moving at least one of the model and the sensor relative to each other in a direction parallel to the longitudinal axis of the model while simultaneously sensing a plurality of distances generated by interaction between the sensor and a surface of the model to obtain a first set of data. The preset conditions and the first set of data are transmitted to at least one control for controlling at least one working tool for producing the three-dimensional body.
