Abstract: The present invention is directed to a bar code symbol having stored thereon a data structure. The data structure includes a plurality of module elements. Each module element is configured as a bar symbol or a space symbol. The data structure includes a start character containing predetermined number of module elements. The predetermined number of module elements is configured in a predetermined pattern of bars and spaces. A data portion is configured to encode a single numerical value. The data portion has one termination data character and 0 to N Continuation characters, wherein N is an integer value. The data structure also includes a stop character.

Abstract: A shock isolator having a spring members such as a belleville washer for supporting a static weight with the belleville washer toggleable between a support condition and a nonsupport condition with the belleville washer having a collapse force that is sufficiently high so that the belleville washer can support a static load without collapsing in order to normally maintain an elastomer damping material in a condition free or substantially free of static forces. When a dynamic force exceeds the collapse force of the belleville washer the belleville washer toggles to a collapsed condition leaving the elastomer to tensionally respond to both the static and the dynamic forces by expansion and contraction of the elastomer.
