Abstract
An apparatus for damping involuntary hand motions occurring in at least first and second directions is provided, the first direction being opposite the second direction. The apparatus is securable to a hand and a forearm and comprises at least a first body having a terminal movable in an internal space in the body. The body contains a Non-Newtonian fluid. A link connects the terminal to a first portion of the apparatus.
Claims15
An apparatus for damping involuntary hand motions comprising:
- a first portion securable to a hand;
- a second portion securable to a forearm and movable relative to the first portion;
- at least one body comprising:
- a casing defining an exterior surface and a spherical interior space having a port extending from the exterior surface into the interior space, the casing directly connected to either the first portion or the second portion;
- a connector comprising:
- a spherical terminal filling the interior space save for a gap between the terminal and the wall of the interior space;
- and,
- a link passing through the port and connecting the terminal to the portion of the first and second portions to which the casing is not directly secured;
- and,
- a shear thickening fluid filling the gap between the terminal and the wall of the interior space, the shear thickening fluid having a viscosity that increases when the shear rate of the terminal increases.
An apparatus for damping involuntary hand motions occurring in at least first and second directions, the first direction being opposite the second direction, the apparatus comprising:
- a first portion securable to a hand;
- a second portion securable to a forearm and movable relative to the first portion;
- and
- at least one body secured to the second portion and comprising
- an exterior surface, an interior space containing a Non-Newtonian fluid, a port extending from the exterior surface into the interior space,
- a terminal in the interior space movable between first and second positions and biased toward the first position, the first position being located farther away from the first portion than the second position, and
- a link passing through said port and connecting the terminal to the first portion;
- wherein
- when the first portion is secured to the hand and the second portion is secured to the forearm, the link is in tension, and
- the involuntary hand motions in the first direction move the terminal from the first position toward the second position.
