Magnetic field sensing device with calibration for safety checks
A recently granted patent (Publication Number: US11774234B2) describes a method for calibrating and performing safety checks on a magnetic field sensing device. The method involves sensing a magnetic field using the device and collecting signal values corresponding to different components of the magnetic field. The device then determines calibration points and angular positions based on these signal values. It calculates calibration parameters using the calibration points and angular positions and utilizes these parameters to perform safety checks. The results of the safety checks are then outputted by the device.
The patent also discloses a method for obtaining signal values from a magnetic field using a sensing device. The sensing device collects sensor data associated with a magnetic field within a measurement range of less than 360 degrees. It determines calibration points and angular positions based on the collected signal values and calculates calibration parameters using these points and positions. The device then performs safety checks using the calibration parameters and outputs the results of these checks.
The method for calculating the calibration parameters involves performing ellipse regression by solving a set of overdetermined equations. The resulting matrix of values includes specific elements that are used to calculate the calibration parameters. The patent describes different scenarios and formulas for calculating the calibration parameters based on the values in the matrix.
The patent also mentions an angle sensor and a system that incorporate the methods described. These devices include processors that perform the calibration and safety check processes using the ellipse regression method.
