摘要： A safety and arming device for a munition is operable to arm and initiate a munition dependent on determining separation from a munition platform, determining detection of free fall of the device for a first time period following separation, initiating a roll manoeuvre of the munition and determining detection of the execution of the roll manoeuvre within a second time period, and generating a munition firing signal, dependent on detection of all of separation, free fall, and the roll manoeuvre.

摘要： A digitally controlled hand-tossable explosive delivery receptacle comprises a ruggedized reusable compartment enclosing a digital circuit and a disposable cartridge holding one or more explosive chemical agents and a primer. The disposable cartridge is configured to be mounted to the ruggedized reusable cartridge, and a high-strength bulkhead incorporated into the reusable or disposable compartment that separates the digital circuit from the chemical agents. The reusable compartment is sufficiently ruggedized to withstand the ignition of the primer and the detonation of the chemical agents to be reused with one or more additional disposable cartridges. In one implementation, the delivery receptacle uses a commercial airbag initiator as the primer, which is arranged in relation to the one or more chemical agents so that when the initiator is activated, it generates a pressure wave that expels the one or more chemical agents from the grenade.

摘要： A fuze for an airburst munition determines a corrected muzzle velocity via an on board acceleration sensor and processor and corrects an airburst time, accordingly. Velocity calculations are made in real time which allows for timely update of airburst time thereby preventing error stack up due to muzzle velocity variations.

摘要： A proximity fuse includes an electric-field (E-field) sensor to detect electrical disturbances from an object that is external and distinct from a device carrying the proximity fuse. The E-field sensor detects or senses E-fields versus time in order to provide omnidirectional coverage of the device carrying the proximity fuse. When the device carrying the fuse is a missile having warhead, the proximity fuse is connected with detonation logic that detonates the warhead at a desired time to destroy or neutralize the object, which is typically a threat, such as another missile.

摘要： Disclosed examples include firing control electronic circuits, such as electronic ignition modules (EIMs), electronic detonators and firing circuits for blasting applications, in which a Zener diode or one or more general purpose diodes is connected between a firing capacitor and charging voltage source in a circuit with a detonator ignition element to block voltage below a certain desired level so that the firing capacitor is not charged to enhance safety in the logger mode.

摘要： A detonator for use in a detonating system, which detonator includes discriminating and validating arrangements which sense and validate at least one characteristic of at least one parameter produced by at least one of a light, acoustic, vibratory, magnetic or electrical signal event, and an electronic timer which executes a timing interval in response thereto.

摘要： Method and systems of controlling detonation of a plurality of explosive charges. A controller has a magneto-inductive transmitter to transmit a magneto-inductive signal to a plurality of detonators, each having a receiver to receive the magneto-inductive signal and a respective firing delay time. The method includes, at each of the plurality of detonators, receiving, via the magneto-inductive signal from the magneto-inductive transmitter, a time sync signal; synchronizing a local clock in the detonator based on the time sync signal; receiving, via the magneto-inductive signal from the magneto-inductive transmitter, a firing code; waiting the respective firing delay time from receipt of the firing code, wherein the waiting is clocked by the local clock; and after expiry of the respective firing delay time, triggering a respective explosive associated with the detonator.

摘要： An initiator system includes a firing pin and a piezoelectric-based energy harvester that generates and stores electric energy when impacted by the firing pin. The electric energy is independently available at a first output and second output of the energy harvester. An electronic time delay is coupled to the second output for generation of an electric trigger signal using the electric energy available at the second output. The electric trigger signal is generated at a selected period of time after the electric energy is available at the second output. An initiation-energy generator is coupled to the first output for the storage of electric energy available thereof. The initiation-energy generator is also coupled to the electronic time delay to receive the electric trigger signal, and uses stored electric energy to generate an initiation explosion when the electric trigger signal is received.
