Patent number: 9562755Abstract: A SAFE and ARM mechanism includes an elongated casing having a first end and a second end. A high-G force firing pin is arranged relatively near to the first end and a low-G force firing pin is arranged relatively near to the second end. A detonator is arranged between the high-G force firing pin and the first end. When a G-force within a first range of magnitudes is applied to the casing along its longitudinal axis, the low-G force firing pin is displaced to strike a portion of the high-G force firing pin, and if a G-force within a second range of magnitudes is applied to the casing along its longitudinal axis, the high-G force firing pin is displaced to strike the detonator. The device may become ARMED in response to a centrifugal force generated by spinning the casing on its longitudinal axis.Type: GrantFiled: April 6, 2012Date of Patent: February 7, 2017Assignee: Pacific Scientific Energetic Materials CompanyInventor: Robert S.
