Patent ID: 7316186

Claim:
A MEMS safety and arming mechanism, comprising: a setback slider operable to move in a first direction from a safe position to a latched position in response to a setback acceleration, the setback slider being spring biased against movement in the first direction; an arming slider operable to move in a second direction opposite the first direction, from a safe position to an armed position in response to a deceleration, the arming slider being spring biased against movement in the second direction; a first lock that prevents movement of the arming slider, the first lock comprising a setback sequence pivot that is rotatable from a first position that prevents movement of the arming slider to a second position that allows movement of the arming slider, the second position of the setback sequence pivot being attained when the setback slider reaches the latched position and the arming slider begins movement in the second direction; and a second lock that prevents movement of the arming slider, the second lock comprising a command rotor that is rotatable from a first position that prevents movement of the arming slider to a second position that allows movement of the arming slider, the second position of the command rotor being attained in response to a command arm electrical signal that is generated externally of the MEMS safety and arming mechanism.
