Latest Patents

Haldin's latest patents include a method for thickness measurement using a pulsed eddy current system. This method allows for non-contact measurement of an object's thickness by utilizing a transmitter coil and a receiver coil. The process involves measuring the voltage induced by a decaying magnetic field at multiple time points and calculating the total magnetic flux generated by eddy currents in the object. This innovative approach ensures that the measurements are independent of the distance between the object and the coils.

Another significant patent is a method for determining the present thickness of a work item in a rolling mill. This method involves acquiring a data signal that reflects the time dependence of eddy current decay in the work item. By determining a thickness parameter value based on the acquired signal, Haldin's method computes an instantaneous resistivity value and provides an output signal indicative of the present thickness of the work item.
