Abstract: One example embodiment of the present invention is a control system for an actuator that is controlled by a pulse width modulation (PWM) signal. The control system includes at least two controllers that are connected to the actuator. Each of the controller sends an independent sequence of PWM signal to the actuator. The actuator is controlled by a combination of the PWM signals from all the controllers together. The controllers are synchronized by a clock signal that provides a sequence of periodic clock interval and the PWM signal from each controller occupies a separate and non-overlapping clock interval from the PWM signal of other controllers.

Abstract: A method of determining the location of a point of interest is disclosed. The method comprises the steps of providing an optical detector; capturing an image by the optical detector; obtaining the position and orientation of the optical detector; identifying at least one coordinates of the point of interest within the captured image; mapping the position of the optical detector and the coordinates of the point of interest in a digital elevation model; and determining the location of the point of interest by projecting at least one path from the position of the optical detector through the coordinates of the point of interest in the digital elevation model. A system for determining the location of a point of interest by utilizing the aforesaid method is also disclosed herein.
