The patent application (Publication Number: US20240004274A1) describes an attitude adjusting apparatus and method that involve a driving device with a motor generating a driving force and a controller adjusting the attitude of a target object based on the rotation angle of the motor. The driving device includes a sensing module that generates a magnetic field and a sensing target with a blade that alters the magnetic field. The controller determines the motor's rotation angle by analyzing changes in the magnetic field sensed after a preset waiting time from the motor's rotation termination. The apparatus can include multiple coils, magnetic field sensors, and a feedback control system to ensure precise adjustment within a target threshold range.
Furthermore, the method involves receiving a control command for adjusting the target object's attitude, driving the motor based on the command, determining the rotation angle, and adjusting the attitude by referencing the motor's rotation angle. The sensing module generates a magnetic field, and the sensing target with a blade modifies this field. The rotation angle determination considers changes in the magnetic field sensed after a waiting period. The method can include multiple coils, magnetic field sensors, and feedback control mechanisms for accurate and efficient attitude adjustment. Additionally, the apparatus can be applied to adjust the pan or tilt of a camera, with an additional driving device for adjusting the other axis, all utilizing the same magnetic field sensing technology for precise control and positioning.
