Marine Trim Tab Control Without Angular Position Sensors

The patent combines multiple individual trim tab controls into a single integrated control system. The single control input simultaneously adjusts port and starboard trim tabs based on their respective extension amounts, eliminating the need for separate manual control of each trim tab while maintaining precise control through the controller's ability to independently manage each tab's movement.

The single control input serves multiple functions by controlling both port and starboard trim tabs. The controller interprets the single input signal and automatically distributes appropriate adjustment commands to each trim tab based on pre-stored extension amounts, making the control system universal rather than requiring dedicated controls for each component.

The patent extracts and eliminates the angular position sensors from the control system. Instead of using sensors to detect vessel orientation, the system uses a single control input device that directly provides roll or pitch change information to the controller, which then adjusts trim tabs accordingly without requiring intermediate angular position measurements.

The controller acts as an intermediary between the single control input and the trim tabs. Rather than relying on sensors to measure angular position, the controller receives the control input signal and translates it into appropriate trim tab adjustments based on stored extension data, serving as a mediator that eliminates the need for complex sensing infrastructure.
