Patent ID: 6875241

Claim:
A variable resistance cell device configured to provide a variable resistance response to a load factor, the device comprising: a) an enclosure with first and second chambers; b) an orifice, operatively disposed between the first and second chambers, and sized to provide resistance against fluid flow therethrough; c) a variable viscosity fluid, disposed in the enclosure and displacable between the first and second chambers though the orifice in response to the load factor; and d) the variable viscosity fluid having a viscosity that is variable corresponding to the load factor to vary an ability of the variable viscosity fluid to flow through the orifice; and e) the enclosure being compressible between: 1) a first position in response to a relatively larger load factor having a first larger dimension and in which a lesser amount of the variable viscosity fluid passes through the orifice into the second chamber; and 2) a second position in response to a relatively smaller load factor having a second smaller dimension and in which a greater amount of the variable viscosity fluid passes through the orifice into the second chamber; f) a block, disposed in the enclosure, dividing the enclosure into the first and second chambers and forming the orifice between the block and the enclosure; and g) a cup, formed around the first chamber, to receive the block therein in the second position.
