ABSTRACT:
Angular momentum and banking indicator and acceleration-deceleration and grade indicator for use on trucks, cranes, airplanes, and boats as a multipurpose sensor. A cylinder with a damping fluid includes four symmetrically spaced coils centered radially about a centrally located powered coil in a base of the cylinder and a pendulum suspended from a top of the cylinder which swings over the coils. Coils connected to a signal processing system which provides an angular momentum and banking signal and an acceleration and deceleration or grade indicator signal.
