Title (EN) BUILT IN TEST FOR MEMS VIBRATORY TYPE INERTIAL SENSORS
(FR) TEST INTEGRE DESTINE A DES CAPTEURS INERTIELS DE TYPE VIBRATOIRES MEMS
Abstract: front page image
(EN)The present invention provides a MEMS vibratory type inertial sensor that has some level of built in test to help improve the reliability by helping to identify erroneous or misleading data provided by the inertial sensor. A test signal is injected into one or more of the inputs of the MEMS vibratory type inertial sensor, where the test signal produces a test signal component at one or more of the MEMS vibratory type inertial sensor outputs. The test signal component is then monitored at one or more of the outputs. If the test signal component matches at least predetermined characteristics of the original test signal, it is more likely that the MEMS vibratory type inertial sensor is operating properly and not producing erroneous or misleading data. In some embodiments, the test signal is provided and monitored during the normal functional operate The present invention provides a MEMS vibratory type inertial sensor that has some level of built in test to help improve the reliability by helping to identify erroneous or misleading data provided by the inertial sensor. In one illustrative embodiment, a test signal is injected into one or more of the inputs of the MEMS vibratory type inertial sensor, where the test signal produces a test signal component at one or more of the MEMS vibratory type inertial sensor outputs. The test signal component is then monitored at one or more of the outputs. If the test signal component matches at least predetermined characteristics of the original test signal, it is more likely that the MEMS vibratory type inertial sensor is operating properly and not producing erroneous or misleading data. In some embodiments, the test signal is provided and monitored during the normal functional operation of the MEMS vibratory type inertial sensor, thereby providing on going built in test.
(FR)L'invention concerne un capteur intertiel de type vibratoire MEMS possédant un certain degré de test intégré, afin de contribuer à l'amélioration de la fiabilité grâce à l'identification de données erronées ou trompeuses fournies par le capteur inertiel. Un signal test est injecté dans une ou plusieurs des entrées du capteur intertiel de type vibratoire MEMS, le signal test produisant un composant de signal test au niveau d'une ou plusieurs des sorties du capteur intertiel de type vibratoire MEMS. Le composant du signal test est ensuite surveillé au niveau d'une ou de plusieurs des sorties. Si le composant du signal test correspond au moins à des caractéristiques prédéterminées du signal test original, il y a plus de chance que le capteur inertiel de type vibratoire MEMS fonctionne correctement et ne produise pas de données erronées ou trompeuses. Dans quelques modes de réalisation, le signal test est fourni et surveillé pendant le fonctionnement normal du capteur inertiel de type vibratoire MEMS, mettant en place ainsi un test intégré continu.
