Abstract: Methods and systems for performing automatic speed-based audio control. One method includes receiving, with an electronic control unit included in a vehicle, a speed of the vehicle and receiving, with the electronic control unit, an audio signal. The method also includes accessing, with the electronic control unit, a plurality of equalization curves based on the speed of the vehicle, each of the plurality of equalization curves associated with the speed of the vehicle and each of the plurality of equalization curves defining a gain adjustment for one of a plurality of frequencies, and, for each curve of the plurality of equalization curves, applying the gain adjustment defined by the curve to one of the plurality of frequencies of the audio signal.

Abstract: The present invention relates to centrifugal pumps, and more specifically to a centrifugal pump device with a governor actuated cartridge seal and a method of attaching a centrifugal pump device with a governor actuated cartridge seal. The centrifugal pump comprises a sealing system that prevents undesirable fluid leaking or air ingestion when in operation while allowing ease of installation and maintenance. The governor actuated cartridge seal automatically increases sealing capabilities by urging a movable seal as a function of impeller or engine drive shaft rotational speed. The governors actuate radially so as to present a minimal profile and therefore not introduce a safety hazard. Scalable weights attached to the governors allow predictable calibration and initialization of the pump under varying hydraulic pressures and rotational speeds.
