  • Damping Grease - An Economical Approach to Motion & Noise Control (.pdf)
    is to control motion and noise in mechanical and electromechanical devices. Think of a zoom lens on a 35mm camera. The "velvet feel," virtually silent operation, and the fact that the lens doesn't coast are all the work of a damping grease on the focusing threads. ./cd1913d4-8610-4816-9efa-008c609c2f81
  • Alenia Spazio Optimizes Noise & Vibration Performance of Space Systems
    Alenia Spazio defined and developed an integrated test/simulation process, which allows meeting the tightest micro-gravity and vibro-acoustic requirements inside manned space vehicles. Once in space, on-board conditioning and electric power systems induce noise and vibration levels that potentially
  • 2001 Aurora delivers luxury in a lean package
    Oldsmobile calls "in-your-face luxury." Luxury begins with a standard two-tone leather interior and continues with real burl walnut trim accents on the center console, door panels, and vents. The Aurora is sophisticated, but I didn't feel like I had to wipe my shoes before getting in. From behind

  • Fractional-N Synthesizers (.pdf)
    In 1984 John Wells of Marconi Instruments invented a new solution to the problem of Fractional-N Synthesizers that required the use of no analog components to correct the noise and spurious normally introduced by fractional divider schemes. Marconi Instruments made extensive use
