Abstract: Systems and methods are disclosed for detecting when a magnetic anomaly may impact the quality of data being output by a magnetometer. A plurality of detection algorithms may be performed in parallel on the sensor data. Further, indication of a anomaly from one or a combination of the detection algorithms may cause the magnetometer data to have a reduced contribution in any sensor fusion operation or may be omitted from a sensor fusion operation as desired.
Abstract translation: 公开了用于检测磁异常何时可能影响由磁力计输出的数据的质量的系统和方法。 可以在传感器数据上并行地执行多个检测算法。 此外，从检测算法的一个或组合指示异常可导致磁力计数据在任何传感器融合操作中具有减小的贡献，或者可以根据需要从传感器融合操作中省略。

Abstract: This disclosure provides techniques for guiding a user through a calibration operation of a mobile device having a motion sensor. The user may receive one or more visual cues to aid the user in positioning the device in one or more desired orientations or patterns of motion. The visual cues may be with respect to a virtual three dimensional environment that is responsive to a determined orientation of the device.

Abstract: Systems and methods are disclosed for calibrating a sensor. A recursive least squares estimation may be performed to update a mean and a covariance matrix for samples of data from a motion sensor and a bias estimate for the motion sensor may be derived from the mean and covariance matrix. The motion sensor may be an gyroscope, an accelerometer or a magnetometer.
