Latest Patents

One of his latest patents is titled "Method and apparatus for trimming a dual electric motor marine propulsion system." This invention provides a technique for adjusting the trim of a dual electric motor marine propulsion system. It involves determining offset or calibration signal levels through a calibration sequence. The propulsion units are driven in a nominal direction, such as through a "straight-ahead" command. An operator adjusts levels of drive signals to the propulsion units to compensate for deviations from the desired navigational direction. This adjustment accounts for mechanical and electrical tolerances, variations, and inherent torques associated with the propulsion units. Once the system is calibrated to navigate the craft in the desired direction, the offset values are stored for future control.

Another significant patent by Saunders is the "Dual electric motor stern drive with forward thruster control." This technique provides a method for steering and navigating a watercraft using dual electric motor propulsion units located aft of the transverse centerline. A forward thruster system is positioned forward of the transverse centerline. The rear drive units contribute thrust for navigating the craft in straight-ahead and turning settings. The forward thruster system adds thrust components for sliding movements and additional turning thrust. This system is particularly beneficial for slow-speed navigation, making it ideal for recreational fishing and close-quarters docking.
