Latest Patents

One of Pfaff's latest patents is for a powertrain with an electrically variable transmission that provides improved gradeability. This innovative powertrain includes an engine with an output member and a transmission featuring two motor/generators. The design allows for enhanced performance by selectively resisting or preventing the rotation of the transmission's input member under specific conditions. This improvement is particularly beneficial when the motor/generators are the sole source of torque for propelling the vehicle.

Another significant patent by Pfaff is an active noise control system. This system utilizes a digital signal processor programmed as an adaptive digital filter with output saturation control. The filter monitors its output signal to detect saturation and adjusts its adaptation to prevent further occurrences. This technology aims to enhance audio quality by managing the output signal effectively.
