Title: Michel Torregrosa: Innovator in Accelerometer Technology
Introduction
Michel Torregrosa is a notable inventor based in Beaumont Les Valence, France. He has made significant contributions to the field of accelerometer technology, holding a total of 3 patents. His work focuses on enhancing the accuracy and stability of accelerometers, which are crucial in various applications.
Latest Patents
One of his latest patents is a capacitive accelerometer with a circuit for correcting stray capacitance. This innovative accelerometer includes a silicon capacitive detector and an electronic device that measures the capacitive unbalance of the detector. It provides an output voltage that represents the acceleration. To mitigate the perturbations caused by stray capacitances, a compensation system is integrated to inject a predetermined correcting electric signal into the measurement system. This ensures that the output voltage is substantially proportional to the ratio between the difference and the sum of the capacitances of the detector's capacitors.
Another significant patent is the servo-controlled pendular micro-sensor. This electrostatically servo-controlled micro-sensor features a pendular element that responds to a force representative of a physical quantity to be measured. To counteract the drifts affecting the stability of the micro-sensor, which are generated by unstable parasitic voltages, the electrostatic forces used to draw back the pendular element through servo-control voltages are designed to have a zero mean value. The control voltages are periodic voltages or series of electric signals of equal durations, each ideally having a zero mean value.
