System for Determining Gas Cartridge Actuation State
Abstract
A gas cartridge actuation state determination system includes a puncture pin adapted to abut an end of the gas cartridge. A load sensor coupled to and in line with the puncture pin. A spring bears against the load sensor. The spring's force is such that it is insufficient to cause the puncture pin to be driven through the end of the gas cartridge when the end has not been punctured, but is sufficient to cause the puncture pin to be driven through the end of the gas cartridge when the end has already been punctured. In addition, the spring's force is such that it will be approximately zero after the puncture pin has been driven through the end that has already been punctured. A device coupled to the load sensor determines when the spring force is approximately zero.
