ABSTRACT:
Coulomb islands are charged to create Coulomb forces which are applied between a first and second substrate. The Coulomb islands are used to levitate the first substrate over the second substrate into an equilibrium position. A processing unit monitors the values of capacitors formed between the substrates to provide feedback information to maintain the first substrate in this equilibrium position. The first substrate can be an accelerometer that can be used to calculate the direction and magnitude of a deceleration. The processing unit sends the digital information to a bus coupled to a plurality of air bags. The digital information identifies the appropriate air bags that need to be enabled to minimize the impact of a crash. Vertical changes in acceleration can also be detected making this invention applicable for flight vehicles.
