  • Patent number: 11305675
    Abstract: A disturbance cancellation and generation seat system includes a seat mounted to a structure of a vehicle. The seat is accelerated due to a disturbance acceleration received in the structure and transferred to the seat. A seat control unit generates a force cancellation command signal. An actuation device is connected to the structure and is in communication with the seat control unit. The actuation device in response to receipt of the force cancellation command signal induces a cancellation acceleration motion into the seat which is equal but opposite to and therefore cancels an acceleration motion of the seat induced by the disturbance acceleration.

  • Publication number: 20210220968
    Abstract: An improved clamping device which includes at least one tether insert allowing additional objects or items to be coupled to the clamping device without having to change the physical location of the clamping device itself. The tether insert is selectively coupled to the clamping device and may be quickly detached by pulling the tether insert away from the clamping device. The clamping device also includes a magnet to assist the tether insert in obtaining a proper seat when brought into close proximity to a handle of the clamping device. The tether insert also comprises a bridge which interacts with a tether, either by wrapping or tying the tether to the bridge, or by coupling a clip or other coupling means disposed on the tether to the bridge. The removal of the tether insert does not require the actuation of the clamping device or the object it is being applied to.

  • Patent number: 10393032
    Abstract: An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head mounted to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing an air and fuel mixture at a geometric compression ratio of at least 10:1. A crankshaft is arranged in the cylinder block and rotated by the piston. An intake valve is operatively connected to the cylinder head and controls delivery of air to the cylinder for combustion therein. A mechanism provides a constant peak lift of the intake valve over an angle of rotation of the crankshaft that is at least 5 degrees, i.e., an extended dwell at peak lift. A multi-stage boosting system having first and second gas compressors is selectively controlled to pressurize air that is received from the ambient for delivery to the cylinder. A vehicle having such an engine is also disclosed.
