A configurable windshield wiper system for a variable sweep angle and/or variable sweep speed. The system includes a bidirectional motor, a gearbox, the gearbox having and input shaft operably coupled to the motor and an output shaft; the gear box configured to ratiometrically step down the number of turns at its output shaft relative to its input shaft; a wiper arm for sweeping a surface of a windshield, the wiper arm operably coupled to an output of the gearbox; and a controller in operable communication with the motor, the controller configured to execute an algorithm to control the position and speed of the motor to achieve a configured sweep angle and configured sweep speed for the wiper arm.

Configurable variable sweep variable speed wiper system

A windshield wiper system (WWS) is provided. The WWS includes a brushless direct current (BLDC) motor, a wiper arm and blade, a gearbox/converter operably interposed between the BLDC motor and the wiper arm and blade and a smart motor drive configured to determine a WWS failure condition and to operate the BLDC motor according to the determination.

Fault diagnostics in aircraft windshield wiper systems

A windshield wiper system (WWS) blade assembly is provided. The WWS blade assembly includes a composite frame and a blade that has a length which is normally shorter than a corresponding length of the composite frame. The blade includes first and second ends attachable to corresponding first and second ends of the composite frame, respectively.
