  • Patent number: 10821859
    Abstract: A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. The combined motion of the vehicle relative to the earth and the seat relative to the vehicle results in motion of the seat moving about a virtual pivot point. A user control is provided for adjustment of the location of the virtual pivot point.

  • Patent number: 10814963
    Abstract: A vibration control system for a rotor hub provides vibration attenuation in an aircraft by reducing the magnitude of rotor induced vibratory. The system can include a force generating device attached to a rotor hub which rotates along with the rotor at the rotational speed of the rotor. Vibratory shear force is generated by rotating unbalanced weights each about an axis non-concentric with the rotor hub axis at high speed to create large centrifugal forces. The rotational speed of the weights can be a multiple of the rotor rotational speed to create shear forces for canceling rotor induced vibrations. The amplitude of the generated shear force is controlled by indexing the positions of the unbalanced weights relative to each other, while the phase of the shear force is adjusted by equally phasing each weight relative to the rotor.

It is determined whether the particular system is unhealthy based on the vibration data from the particular system and the first model and the second model and speaker recognition techniques. Some embodiments include obtaining training data that represents vibrations of multiple healthy systems. A damage-sensitive parameter is based on the training data. A threshold value that separates damaged systems from healthy systems is based on the training data and the parameter.

  • Patent number: 9217533
    Abstract: A vibration isolating table is adapted to be disposed between a vibrating body, which vibrates with the playing of a musical instrument, and a floor for suppressing vibration or shock generated by the vibrating body from transmitting to the floor, wherein the vibration isolating table includes: a rigid plate including a plate-shaped member having predetermined rigidity; and a main body portion supporting the rigid plate in a floating condition above the floor. The main body portion is formed of an elastic body having higher elasticity than the rigid plate and includes a bulge means which bulges in a shape tapered from one side to the other side, wherein a lower surface side of the rigid plate is supported by the one side or the other side of the bulge means.

  • Patent number: 9061767
    Abstract: The present invention refers to a device to reduce the vibrations that are produced in the chairs of helicopter pilots due to the movement of the blades of such aircraft. Such device is based on a low weight and cost pneumatic system, that counteracts the vibrations suffered by the pilot, as it neutralizes the movement of the chair's structure making the vibration to be absorbed by a pneumatic ball and is not transmitted to the pilots body. Additionally, the device counts with a support structure coupled to a security mechanism and anchorage, which rests over the pneumatic bellows and vertically displaces over the security mechanism guides damping and isolating the vibrations produced by the aircraft's rotors.
