1. A multi-directional shock sensor, comprising:

  • a central post;

    a toroidal mass surrounding said central post;

    a spring arrangement connecting said toroidal mass with said central post allowing for omnidirectional movement of said toroidal mass;

    a plurality of anchor members surrounding said toroidal mass; and

    a plurality of latching arm assemblies where each latching arm assembly includes a first arm being opposed to a second arm,wherein each said first arm is connected to a respective anchor member of said plurality of anchor members,wherein each said second arm is connected to said toroidal mass, andwherein movement of said toroidal mass due to a shock event causes at least one of said second arm to engage and latch with an opposed one of said first arm, whereby the shock event and direction of said shock event is determined.
