Multidirectional inertial sensor

Abstract

Abstract A CYLINDRICAL SUPPORT HAS A HOLLOW TUBULAR AXIAL GUIDE MOUNTED ON AN END WALL THEREOF. AN OPERATOR IS SLIDABLY MOUNTED WITHIN THE GUIDE AND SPRING BIASED TOWARD ACTUATED POSITION. BALLS MOUNTED WITHIN RADIAL OPENINGS OF THE GUIDE ENGAGE A RADIALLY TAPERED SHOULDER OF THE OPERATOR TO HOLD THE OPERATOR IN NORMAL POSITION AGAINST MOVEMENT. THE BALLS ARE HELD IN ENGAGEMENT WITH THE OPERATOR SHOULDER BY A RETAINER SLIDABLY MOUNTED ON THE GUIDE AND SPRING BIASED AXIALLY OPPOSITE TO THE OPERATOR. AN ANNULAR SEISMIC MASS SURROUNDS THE GUIDE AND FITS BETWEEN THE RETAINER AND AN END WALL OF THE SUPPORT. THREE EQUALLY CIRCUMFERENTIALLY SPACED CONICAL DEPRESSIONS IN EACH END OF THE MASS MATE WITH LIKE DEPRESSIONS IN THE RETAINER AND IN THE SUPPORT. EACH PAIR OF MATING DEPRESSIONS RECEIVES A BALL. WHEN THE MASS RECEIVES AN ACCELERATION PULSE OF PREDETERMINED AMPLITUDE AND TIME, IT SHIFTS RADIALLY OF THE GUIDE, AND THE CAMMING ACTION OF THE BALLS MOVING WITHIN THE CONICAL DEPRESSIONS SHIFTS THE RETAINER AXIALLY AGAINST ITS SPRING BIAS TO RELEASE THE BALLS FROM THE OPERATOR SHOULDER AND IN TURN RELEASE THE OPERATOR.
