Abstract: A system includes a plurality of actuators configured to provide forces to an actuatable member to actuate the member between a first position and a second position during an actuation mode. The actuators are also configured to return the member from the second position to the first position during a retrace mode. The system also includes a controller configured to control the actuators. The controller is configured to identify a back electromotive force (BEMF) of each of the actuators during the retrace mode. The controller is also configured to responsively provide control signals to drive the actuators such that the forces provided by the actuators to the member during the actuation mode are substantially equal.

Abstract: A system and method for interpolating between pixels of an image for providing zoom and pan features. A piecewise cubic spline is used to find the values of each of four provisional interpolation points in each of four rows of an image and, similarly, a piecewise cubic spline is used to interpolate between the provisional interpolation points to find the value of a point in the output image. Boundary conditions used to constrain the coefficients of the piecewise cubic spline provide enhanced quality in the output image.
