  • Publication number: 20210356012
    Abstract: A vehicle active vibration control (AVC) system includes a vehicle having at least an engine, a transmission, a controller area network (CAN) bus, a frame, and a cabin. The vibration control devices (120) are distributed about the frame, with each device including a circular force generator (CFG) (122). At least one sensor is positioned on the frame to detect and measure a noise and/or vibration within the cabin. Each sensor creates an electronic data signal and electrically communicates with a corresponding vibration control device. Each vibration control device receives an electronic data signal from a corresponding sensor and vehicle data from the CAN bus. Each vibration control device processes the electronic data signal and the vehicle data. The CFG of each vibration control device generates a vibration canceling force having a magnitude and phase that attenuates noise and/or vibration within the cabin.

  • Patent number: 11130587
    Abstract: The invention relates to an improved throttle control system for an aircraft. The throttle system includes providing friction to the throttle to maintain the position of the throttle until the pilot overcomes the friction by using force to move the throttle. The throttle is attached to and positioned about a shaft to provide rotatable movement. The invention uses a first and second friction resistance to maintain the position of the throttle along with an automatic regulating device capable of automatically controlling rotation of the shaft having a geared motor assembly.
