ABSTRACT:
The detector has two disc shaped magnets that are magnetized through their respective thicknesses. One magnet is fixedly coupled to a container, and the other magnet is left free to slide transversely with respect to the fixed magnet. The magnets are oriented so that the opposite poles of the magnets are adjacent to each other. In the absence of a shock acting on the container, the free magnet remains in a centered position with respect to the fixed magnet. Indicating apparatus is provided to indicate when the free magnet is moved to an off-center position due to an accelerational force, and the direction of the accelerational force. In one embodiment, the indicating apparatus includes a marking device coupled to the free magnet and a recording surface coupled to the container. In another embodiment, the indicating apparatus includes a transparent cover and tabs for retaining the off-center free magnet.
