Abstract
Methods and apparatus for sensing acceleration according to various aspects of the present invention comprises a non-rigid membrane and a switching latch electrically coupled to the membrane. The membrane is responsive to acceleration forces and is configured to produce a signal as a result of deflections in the membrane caused by acceleration. The signal is transmitted to the switching latch causing a change in state of the switching latch. This change in state allows a second signal to be sent to an activating device such as a squib.
