1. A servoed accelerometer comprising:

  • a housing configured in a generally cylindrical shape;

    a one-piece support frame secured within said housing;

    a pendulum;

    support means secured to said support frame, including an axle, for supporting said pendulum generally parallel to the cylindrical axis of said housing wherein said axle is secured transversely to said pendulum;

    position detecting means for generating a signal representing the rotational position of said pendulum in said housing with respect to the cylindrical axis of said housing;

    restoring means, including a magnetic assembly secured to said support frame and a torque coil secured to said pendulum, for rotating said pendulum to a predetermined position generally parallel to the cylindrical axis of said housing;

    a generally rectangular shaped circuit support member secured at each end within said support frame above and generally parallel to said pendulum; and

    an electronic circuit secured to one side of said circuit support member and electrically connected to said position detecting means, said pendulum and said torque coil effective to generate a restoring current in said torque coil for moving said pendulum to said predetermined position when said pendulum has moved with respect to the cylindrical axis of said housing in response to an acceleration force.
