    • A propeller related vehicle in accordance with one embodiment of the present invention is described as a helicopter having an airframe housing a pneumatic motor mechanism for powering a main propeller attached to a main drive shaft. The helicopter further includes a horizontal stabilizing means attached between the main propeller and the main drive shaft, which permits the main propeller to freely pivot about the main drive shaft independently from the airframe. As such when the main propeller is rotating and the main propeller begins to pitch, the rotating main propeller has a centrifugal force created by the rotation thereof and will tend to pivot about the horizontal stabilizing means in a manner that offsets the pitch such that the helicopter remains in a substantially horizontal position.
    • 根据本发明的一个实施例的螺旋桨相关车辆被描述为具有机身的直升机,该机身容纳用于为附接到主驱动轴的主螺旋桨供电的气动马达机构。 直升机还包括安装在主螺旋桨和主驱动轴之间的水平稳定装置,其允许主螺旋桨独立于机身围绕主驱动轴自由枢转。 因此,当主螺旋桨旋转并且主螺旋桨开始俯仰时,旋转主螺旋桨具有由其旋转产生的离心力,并且将倾向于以水平稳定装置的方式枢转,以使得俯仰偏移使得直升机 保持在基本上水平的位置。

    • A propeller related vehicle in accordance with one embodiment of the present invention is described as a helicopter having an airframe housing a motor mechanism for powering a main propeller attached to a main drive shaft that extends vertically through the airframe and for powering a tail rotor. The helicopter further includes a horizontal stabilizing mechanism attached between the main propeller and the main drive shaft, which permits the main propeller to freely pivot about the main drive shaft independently from the airframe. As such when the main propeller is rotating and the main propeller begins to pitch, the rotating main propeller has a centrifugal force created by the rotation thereof and will tend to pivot about the horizontal stabilizing mechanism in a manner that offsets the pitch such that the helicopter remains in a substantially horizontal position. In addition various main propeller configurations may be employed that provide additional self-stabilization.

    • A line cord filter assembly for providing EMI shielding includes at a first end thereof a first plug for connecting to a power source external of a chassis and having at a second end thereof a second plug for connecting to electronic components disposed internally of the chassis. An elongated electrically conductive block has a serpentine shaped channel disposed in an inner surface thereof and extending between the first end and the second end. A electrical cable is disposed in the channel, having an inner electrical conductor and an outer electrical insulator, the electrical conductor electrically connected to the first end and the other end of the electrical conductor electrically connected to the second end. An electrically conductive, deformable sheet is disposed on the electrically conductive block over the outer electrical insulator with portions of the sheet projecting into portions of the channels around portions of the outer electrical insulator disposed within the channel.
