Patent ID: 7311013

Claim:
A biomass height and density system comprising: a means for sensing biomass height and density, and a control system; said means for sensing biomass height and density has a means for communicating to said control system; said control system having a means for calculating said biomass height and said density; whereby said means for sensing biomass height and density comprises one or more frames and a plurality of pendulums; each pendulum comprising a hinge, a rod, and an angular deflection sensor whereby: said hinge is attached to a frame from said one or more frames; said rod has a length; said rod is attached to said hinge whereby said rod is freely rotatable along a free axis creating an angle between said attached frame and said rod; said free axis is perpendicular to said length of said rod; said angular deflection sensor has a means for measuring said angle between said attached frame and said rod; and said angular deflection sensor has a means for communicating to said control system; and each said rod has a size and shape whereby each said rod is deflected from said biomass at a height unique from any other rod.
