    • Microelectromechanical (MEM) safe-arm devices comprise a substrate upon which a sense mass, that can contain an energetic material, is constrained to move along a pathway defined by a track disposed on the surface of the substrate. The pathway has a first end comprising a “safe” position and a second end comprising an “armed” position, whereat the second end the sense mass can be aligned proximal to energetic materials comprising the explosive train, within an explosive component. The sense mass can be confined in the safe position by a first latch, operable to release the sense mass by an acceleration acting in a direction substantially normal to the surface of the substrate. A second acceleration, acting in a direction substantially parallel to the surface of the substrate, can cause the sense mass to traverse the pathway from the safe position to the armed position.
    • 微机电(MEM)安全臂装置包括基底,在其上可以包含能量材料的感测质量被限制为沿着设置在基底表面上的轨道限定的路径移动。 该通道具有包括“安全”位置的第一端和包括“武装”位置的第二端,其中第二端可将感测质量块靠近包含爆炸火车的能量材料对准在爆炸性部件内。 感测质量可以通过第一闩锁限制在安全位置,可操作以通过沿基本上垂直于衬底的表面的方向作用的加速度来释放感测质量。 沿基本上平行于基板表面的方向作用的第二加速度可以使感测质量穿过从安全位置到布防位置的路径。
