FORCE COMPENSATION SYSTEMS AND METHODS
First Claim
1. A positioning control system associated with a camera, the system comprising:
- an external force sensor configured to measure a magnitude of at least one external force acting upon a movable object disposed within the camera and to generate a force signal that is indicative of the magnitude of the at least one external force;
a positioning motor configured to control a physical location of the movable object in response to a positioning signal; and
a position controller configured to generate the positioning signal at a magnitude that is adjusted in response to the force signal to substantially compensate for the at least one external force in controlling the physical location of the movable object.

Abstract
A positioning system and method are disclosed. The system includes an external force sensor configured to measure a magnitude of at least one external force acting upon a movable object disposed within a camera and to generate a force signal that is indicative of the magnitude of the at least one external force. The system also includes a positioning motor configured to control a physical location of the movable object in response to a positioning signal. The system further includes a position controller configured to generate the positioning signal at a magnitude that is adjusted in response to the force signal to substantially compensate for the at least one external force in controlling the physical location of the movable object.

8. A method for positioning a camera lens in a camera, the method comprising:
-
generating a positioning signal having a magnitude corresponding to one of moving the camera lens to and maintaining the camera lens at a desired location; measuring a magnitude of at least one external force acting upon the camera relative to a fixed plane in three-dimensional space; calculating a magnitude of a force acting upon the camera lens that is associated with the at least one external force; and adjusting the magnitude of the positioning signal to substantially compensate for the calculated force in the one of moving the camera lens to and maintaining the camera lens at the desired location. - View Dependent Claims (9, 10, 11)

12. An electronic device comprising a camera lens, the electronic device comprising:
-
a sensor configured to measure at least one of a yaw, pitch, and roll angle orientation associated with the camera lens relative to a fixed plane and to generate a force signal that is indicative of a magnitude of at least one external force based on the measured at least one of the yaw, pitch, and roll angle orientation associated with the camera lens; a positioning motor configured to control a physical location of the camera lens relative to a fixed plane in three-dimensional space in response to a positioning signal; and a position controller configured to generate the positioning signal at a magnitude that is adjusted in response to the force signal to substantially compensate for the at least one external force. - View Dependent Claims (13, 14, 15)
