ABSTRACT:
A motion of a first pendulous mass responsive to combinatorial gravitation and acceleration force vectors in a first plane is kinetmatically coupled to cause displacement of an indicator needle in a second plane that is orthogonal to the first plane. Also in an accelerometer/inclinometer, a second pendulous mass moves responsively to combinatorial force vectors in the second plane, and causes displacement of another indicator needle in this same second plane. The first plane is nominally aligned longitudinally in a vehicle while the second plane is aligned laterally. By this alignment each of the longitudinal, or fore-aft, and the lateral, or side-to-side, combinatorial tilts and accelerations of the vehicle are displayed.
