Patent ID: 7075623

Claim:
A reaction mass apparatus, comprising: a baseframe with a first end having a first connection area and a second end having a second connection area; at least one reaction mass with a first end having a first connection area and a second end having a second connection area; at least one first bearing mechanism that each connects one of said at least one reaction mass first connection area to said baseframe first connection area; and at least one second bearing mechanism that each connects one of said at least one reaction mass second connection area to said baseframe second connection area, wherein said baseframe, said at least one reaction mass, said at least one first bearing mechanism, and said at least one second bearing mechanism are arranged such that when a force is applied to said at least one reaction mass causing said at least one reaction mass to move in a direction from said first end toward said second end, a center of mass of said at least one reaction mass moves substantially linearly.
