Abstract
This process involves detecting piezo-electric potentials which are characteristic of a mechanical strain exerted on a long rigid member made of organic material. For this purpose, the potentials at two points spaced apart on this member are measured by means of two operational amplifiers CI.sub.1 and CI.sub.2 in order to obtain a signal which is characteristic of the stress rather than of its derivative and these signals are processed by means of analog operators OA.sub.1, OA.sub.2, OA.sub.3 in order to identify the bending .DELTA. F and torsional T stresses which are then compared with reference values RT, RF in order, for example, to trigger a signal. This process can be used for opening a safety ski binding.
