  • Publication number: 20140079234
    Abstract: A noise-suppression assembly of a mechanical drive system having a rotational frequency includes an audio filter unit configured to receive a first audio signal and a timing signal of the mechanical drive system. The audio filter unit generates a noise-cancellation signal based on a frequency of the timing signal to suppress a noise generated by the mechanical drive system and to apply the noise-cancellation signal to the first audio signal to produce a filtered first audio signal. The frequency of the timing signal is based on the rotational frequency of the mechanical drive system.

  • Patent number: 8454315
    Abstract: A method and device for reducing vibratory noise in a system with an integral rotating member includes independently operable drive systems for controlling the angular velocity of at least two independently rotatable masses. Control signals manipulate the drive system to rotate each mass at optimal speed, direction and phase to reduce noise induced in the system by the rotating member.

  • Patent number: 8038394
    Abstract: A rotor system includes a multiple of rotor blade yokes mounted to a rotor hub. A lead/lag damper is mounted to each of the rotor blade yokes and to a damper hub. An actuator system is operable to shift a damper hub axis of rotation relative the rotor axis of rotation to minimize 1P damper motions. A method of minimizing 1P damper motions within a rotor system includes shifting the damper hub axis of rotation relative the rotor axis of rotation to oscillate an inner connector of each lead/lag damper in phase with a 1P blade motion to minimize the 1P motion of the damper.

  • Publication number: 20110113671
    Abstract: A night sight includes a notched bottom portion, permitting the use of a large objective lens for maximized light gathering capability while also permitting the night sight to be mounted with its center line relatively close to the center line of the barrel of the weapon with which it is used. This configuration permits the night sight to be mounted so that its center line is the same as the center line of a daytime telescopic sight used in conjunction with the night sight. The night sight includes a focusing assembly having decreased sensitivity to tilt or decenter, and a collimator mounted within a spherical bearing so that the collimator may be precisely aligned during assembly of the night sight. The night sight thereby ensures that an image viewed through the night sight appears to originate from the same angle as that with which the image entered the objective lens, and further resists a need to compensate for parallax during aiming.

  • Patent number: 7648338
    Abstract: A dual, counter-rotating, coaxial rotor system provides individual control of an upper rotor system and a lower rotor system. The lower rotor control system and the upper rotor control system provide six controls or “knobs” to minimize or theoretically eliminate airframe vibration. In a dual, counter-rotating, coaxial rotor system, application of a HHC system to the two rotor systems individually but located on the common axis, will yield essentially complete vibration reduction because the 6 controls will suppress the 6 loads.
