| 摘要 |
A device for affording an indication when a predetermined mechanical shock has been received, characterized by a base, or means for attaching to a container to be monitored; structure for measuring when a predetermined acceleration has been received by the container and the device; and an indicator for indicating to an observer that the shock has been received. Disclosed are devices having (1) a mechanical structure with a breaking point; (2) a mechanical structure with a biasing means; and (3) a structure employing an interfacial tension phenomenon. The devices may be of the "go-no go" type or may afford an indication and history of the shock, or acceleration forces, received. Also disclosed are the specific details of the respective embodiments.
