Abstract:
A system and method are provided related to replacing components of a fully assembled torque sensor system having been previously calibrated, whereby the new system with its new components, which may be installed in a larger system, can be recalibrated at the location where the component replacement or servicing occurs. Individual components are provided with individual characteristics information, either on or associated with the shipped component, so the end user may retrieve the information and enter it in the software, such as that associated with a control unit, which is used with the fully assembled torque sensor. A database storing information about each manufactured component and their respective characteristics information, and fully assembled systems and their collective characteristics information, may be maintained and accessible by end users.
Abstract:
A method for estimating one or more of the following quantities from an electromechanical machine and/or component, the method comprising the creation of a photorealistic numerical model of the electromechanical machine or parts of it, a measurements step for combining outputs of physical sensors of which at least one is an imaging device for visualising the external surface of the physical electromechanical machine in at least one 2 dimensional image, an estimation step combining the photorealistic numerical model and measurement step to provide an estimate of desired electromechanical quantities, wherein the estimation step is based at least on the usage of a similarity metric between the (at least one) two dimensional image of the electromechanical machine or parts of it and the images generated by the photorealistic numerical model.

Abstract:
A method for calibrating a force platform includes, providing a force platform and applying an nXm grid on a top surface of the force platform via a computing device. Next, applying p known loads on each of the nXm grid points of the top surface along a Z-axis being perpendicular to the X and Y axes and along the X and Y axes. Next, taking multipoint measurements at each grid point and for each applied known load along the X,Y and Z axes and generating six measured output signals, exact position coordinates and applied known load magnitude for each grid point. Next, assembling an array of nXmXp of six equations with six unknown for each grid point and applied known load and then solving the assembled equations and deriving a position and load specific calibration matrix for each grid point.
