Abstract
A pressure delay mechanism is disclosed. In various embodiments, the mechanism includes a triggering mechanism operably coupled to an input signal port and to an output signal port and configured to transmit a signal from the input signal port to the output signal port and a differential pressure mechanism operably coupled to an exterior pressure input and to an interior pressure input and configured to lock the triggering mechanism during a first state of pressure difference and to unlock the triggering mechanism during a second state of pressure difference.
