to a pre determined differential pressure is maintained for at least a pre determined amount of time and a second means for determining whether power supplied to the follow through warhead arming and validation logic 28 is within a predetermined range of frequency and amplitude the second means for determining whether the weapon has experienced a transition from no differential pressure to a pre determined differential pressure and that the transition to a pre determined differential pressure is maintained for at least a pre determined amount of time is selected from the group of means consisting of an fpga electrically associated with the at least one pressure sensor the fpga being configured and programmed to determine whether the weapon has experienced a transition from no differential pressure to a pre determined differential pressure discrete circuitry adapted to determine whether the weapon has experienced a transition from no differential pressure to a pre determined differential pressure and an integrated circuit configured and programmed to determine whether the weapon has experienced a transition from no differential pressure to a pre determined differential pressure the second means for determining whether power supplied to the follow through warhead arming and validation logic 28 is within a predetermined range of frequency and amplitude is a different technology than the technology of the second means for determining whether the weapon has experienced a transition from no differential pressure to a pre determined differential pressure and is selected from the group of technologies adapted to determine whether power supplied to the follow through warhead arming and validation logic 28 is within.
