摘要： A method for calibrating the sensitivity of a micromachined differential-capacitor accelerometer without applying mechanical stimulation, such as shaking. The accelerometer is fabricated with dimensional control structures so that a dimensional relationship is set-up among operational features of the device. The method includes measuring the resonant frequency of a movable mass and measuring the change in the output signal of the accelerometer as the mass is displaced by electrostatic means. The sensitivity of the accelerometer is then calculated.

摘要： A system, computer program product and method of obtaining a performance parameter associated with a sensor, such as an accelerometer, is provided. The method includes applying an acceleration to the accelerometer and a first frequency to obtain a sensitivity of the accelerometer at the first frequency. A first self-test is performed on the accelerometer. The first self-test includes stimulating the accelerometer with a first self-test stimulation signal encoded with the first frequency, such that the accelerometer outputs a first signal. A self-test equivalent acceleration is then determined based, at least in part, on the first signal and the accelerometer sensitivity at the first frequency. A second self-test is performed on the accelerometer. The second self-test includes stimulating the accelerometer with a second self-test stimulation signal encoded with the second frequency, such that the accelerometer outputs a second signal. A parameter of the accelerometer is determined at the second frequency based, at least in part, on the second signal and the self-test equivalent acceleration. The parameter may be sensitivity of the accelerometer at the second frequency.

摘要： In an inertial sensor, a mass is supported by a number of mass support structures positioned within an inner periphery of the mass. The mass support structures are affixed to a substrate by at least one anchor positioned proximate to the mass' center of mass. A number of sensing fingers are affixed to the mass support structures.

摘要： A method and system for determining camera positioning information from an accelerometer mounted on a camera. The accelerometer measures the orientation of the camera with respect to gravity. Orientation measurement allows user interface information to be displayed in a “right side up” orientation on a viewfinder for any camera orientation. Alternatively, an artificial horizon indicator may be displayed in the viewfinder. The accelerometer may also measure camera movement. Camera movement information together with camera orientation can be used to determine camera usage. Additionally, camera movement information can be used to determine a minimum shutter speed for a sharp picture.
