Abstract

A device, comprising: a position sensor including an optical sensing element and an image processor, the image processor being configured to use the optical sensing element to take images of a visual mark that is formed on a target, detect a position of the target based on the images, and generate a first signal that is indicative of the position of the target; a current sensor including one or more magnetic field sensing elements, the current sensor being configured to measure a level of electrical current through a conductor, and generate a second signal that is indicative of the level of the electrical current through the conductor; and a motor controller that is configured to receive the first and second signals and generate a third signal for powering an electric motor, the third signal being generated based on the first and second signals; and a semiconductor package.
