    Abstract: A method for sensor diagnostics in a seat suspension system includes: generating, by a rotational position sensor, based on a rotational position of an output shaft coupled to a suspension mechanism to move a vehicle seat relative to a vehicle body, an output signal including a sine output and a cosine output; determining, based on the sine output and the cosine output, a diagnostic indicator value; and determining, based on the diagnostic indicator value, an accuracy of the output signal to represent the rotational position of the output shaft. A second method determines accuracy of an output signal to represent a rotational position of the output shaft in a seat suspension system using the output signal and a motor position signal representing a rotational position of a motor shaft coupled to the output shaft such that rotation of the motor shaft causes rotation of the output shaft.

    Abstract: A steering system for a marine craft includes a steering input shaft. The steering system also includes an electric power steering (EPS) system operatively coupled to the steering input shaft, the EPS system having an electric motor that drives rotation of a system output shaft. The steering system further includes a hydraulic pump operatively coupled to the system output shaft with a gear set, the hydraulic pump having a longitudinal direction that is perpendicular to a steering input shaft axis. The steering system yet further includes a fluid reservoir located remotely relative to the hydraulic pump.

    Abstract: A seed depth device for an agricultural planter includes an electric motor, an actuator, a stop, a controller, and a seed depth auto-learn system. The actuator is driven by the electric motor, and is constructed and arranged to move between a home position and a full extension position. The stop is proximate to the actuator when in the home position. The controller includes a computing processor and a computer readable storage medium configured to control the electric motor. The seed depth auto-learn system is, at least in-part, stored and executed by the controller. The seed depth auto-learn system is configured to learn the home position based, at least in-part, on the actuator stalling upon the stop.
