Patent ID: 8267014

Claim:
A method of manufacturing an ejection device including the steps of: obtaining a housing, the housing having an ignition source receiving bore including a bore wall, the bore wall having a plurality of independently actionable shear disks, each independently actionable shear disk being associated with an independent payload bore located within the housing such that the shear disk, when seated, prevents pressure from passing from the ignition source receiving bore to one of the payload bores, and the shear disk, when unseated, allowing the transmission of pressure from the ignition source receiving bore to one of the payload bores; placing an ejectable device within each payload bore of the housing; placing a piston located between the shear disk and the ejectable device; placing a cap on the end of each payload bore to contain the ejectable device within the payload bore; wherein said bore wall extends through said housing and is adapted to permit said piston, ejectable device, and end cap to exit said housing, said bore wall further comprising a retaining structure adapted to receive and retain said shear disk in a seated mode and release said shear disk upon an ignition mode, said ignition mode comprising said transmission of pressure from the ignition source.
