Abstract:
1. A microelectromechanical (MEM) apparatus comprising: a substrate; an interrupting member slideably connected to the substrate, the interrupting member having an interrupted state and an uninterrupted state, wherein said interrupting member defining an aperture, wherein said interrupting member comprises an explosive train that includes an energetic material, a detonator, and an initiator; at least one latching member slideably connected to the substrate, the at least one latching member having an engaged state and a disengaged state and, operatively arranged to engage the interrupting member in the engaged state, and disengage the interrupting member in the disengaged state; and, a first set of actuators for actuating the interrupting member and a second set of actuators for actuating the at least one latching member, said first set of actuators operatively connected to the substrate, whereby said second set of actuators causes the at least one latching member to be in the state selected from the group consisting of the engaged state and the disengaged state, and said first set of actuators causes the interrupting member to be in the state selected from the group consisting of the interrupted state, and the uninterrupted state, whereby the interrupting member is prevented from changing state, when the at least one latching member is in the engaged state.
