Abstract:
1. A damping apparatus comprising: a payload member; a housing surrounding the payload member; an extension member coupled to the payload member, such that a movement of a first distance by the payload member results in a movement of a second distance by the extension member, the second distance greater than the first distance, the extension member having an elongated portion extending outwardly from the payload member through the housing, the elongated portion having an end fixed to the payload member; a damping member for applying a first damping force to the extension member in response to the movement of the extension member, a plurality of magnets arranged circumferentially around the housing; and at least one conductive vane coupled to the extension member, wherein the at least one conductive vane extends radially between a pair of the plurality of magnets; wherein application of the first damping force to the extension member provides a second damping force on the payload member, the second damping force greater than the first damping force.
