Patent ID: 6993849

Claim:
A leveling system comprising: a bubble chamber enclosing a fluid and defining a bubble therein; an upper capacitor plate contacting at least a portion of said fluid; a first capacitor plate contacting said fluid and disposed in a substantially parallel relationship with said upper capacitor plate; a second capacitor plate contacting said fluid and disposed in a substantially parallel relationship with said upper capacitor plate coaxial with said first capacitor plate; a third capacitor plate contacting said fluid and disposed in a substantially parallel relationship with said upper capacitor plate; a fourth capacitor plate contacting said fluid and disposed in a substantially parallel relationship with said upper capacitor plate coaxial with said third capacitor plate; wherein movement of said bubble results in capacitance signals generated from at least two of said first capacitor plate, said second capacitor plate, said third capacitor plate, and said fourth capacitor plate; and a processor receiving said capacitance signals and leveling said bubble chamber in response thereto.
