Accelerometer with vibrating sensors for measuring acceleration
A recently granted patent (Publication Number: US11965907B2) discloses an innovative apparatus comprising two identical vibrating sensors with fundamental and higher-order vibrational modes. These sensors are driven at selected resonant mode frequencies by excitation-and-detection circuits, resulting in a difference frequency that varies linearly with acceleration along the sensing axis. The difference frequency remains non-zero at zero acceleration and does not change sign over the operational range of acceleration. Additionally, a processing module is included to generate measurements based on the difference frequency or functions of the resonant mode frequencies, compensating for factors like temperature variations, pressure, humidity, and aging of the apparatus.
The apparatus further includes features such as phase-locked-loop arrangements for the sensors, low-pass filtering of output signals, and compensation algorithms based on statistical or machine learning methods. The vibrating sensors can be made from materials like crystalline quartz or silicon, arranged collinearly and parallel to the sensing axis. A linking member connected to a proof mass forms a pendulum constrained to move in a specific plane, enhancing the accuracy of acceleration measurements. The integration of multiple layers of materials or a single continuous volume in the construction of the apparatus ensures structural integrity and precision in detecting acceleration along the sensing axis. These unique features and functionalities make this patented apparatus a significant advancement in the field of sensor technology, offering improved accuracy and reliability in measuring acceleration for various applications.
