  • Sensor devices and methods for calculating an orientation while accounting for magnetic interference
    Patent number: 10310129
    Abstract: Sensor devices and methods for calculating an orientation of a sensor device including a magnetometer are disclosed. In one embodiment, a method of computing an orientation of a sensor device includes receiving a current magnetic field reading including at least a magnetic field magnitude, calculating a difference between the current magnetic field magnitude and a reference magnetic field magnitude, and comparing the difference between the current magnetic field magnitude and the reference magnetic field magnitude with a threshold. The method further includes adjusting a trust value of the magnetometer such that the trust value is decreased if the difference between the current magnetic field magnitude is greater than or equal to the threshold, and computing an orientation of the sensor device based at least on the trust value and the current magnetic field reading, wherein the trust value affects a reliance on the magnetic field reading in computing the orientation.
