International Classification:
F16M 100
US Classification:
26714014
Abstract:
A vibration control system is provided for an appendage such as an antenna 10 coupled to a platform such as a spacecraft 12. The antenna 10 is coupled at a base 14 so as to extend from the spacecraft 12. A plurality of guidelines 20 extend between remote portions 22 of the antenna 10 and the antenna base 14. A plurality of motion control elements 36 are provided within the antenna structure for reducing oscillation settling time of the antenna 10 relative to the spacecraft 12. The motion control elements 36 include a material disposed therein having its damping response changed according to the magnitude of an electric or magnetic field applied thereto.

ara could take on ExxonMobil, officials have sought to downplay the prospect of the two survey ships running into trouble. Addressing reporters, the US ambassador to Nicosia, Kathleen Doherty, said activity would be limited to environmental and archaeological research in an area south-west of Cyprus.
