| Abstract: Microelectromechanical (MEM) apparatus and methods for operating, for
preventing unintentional detonation of energetic components comprising
pyrotechnic and explosive materials, such as air bag deployment systems,
munitions and pyrotechnics. The MEM apparatus comprises an interrupting
member that can be moved to block (interrupt) or complete (uninterrupt)
an explosive train that is part of an energetic component. One or more
latching members are provided that engage and prevent the movement of the
interrupting member, until the one or more latching members are
disengaged from the interrupting member. The MEM apparatus can be
utilized as a safe and arm device (SAD) and electronic safe and arm
device (ESAD) in preventing unintentional detonations. Methods for
operating the MEM apparatus include independently applying drive signals
to the actuators coupled to the latching members, and an actuator coupled
to the interrupting member. |
