1. Apparatus for indicating angular displacement comprising:

  • a frame,housing means,means pivotally supporting said housing means relative to said frame for rotation about a pivot axis in first and second angularly displaced orientations of said pivot axis when said frame is oriented in first and second positions, respectively,movable mass means attached to said housing means for providing a balanced distribution of weight around said pivot axis in the said first angularly displaced orientation when said frame is oriented in said first position and for providing and offset weight distribution relative to said pivot axis in said second angularly displaced orientation when said frame is oriented in said second position,means tracking the relative rotational movement between said housing means and said frame for producing digital signals corresponding to discrete increments of said relative movement,a digital signal utilizing circuit, andmeans for coupling said digital signals to said utilizing circuit except when said relative movement is substantially at the boundary between successive said discrete increments.
