A smart insulation displacement connector for use in a blasting system with a blast machine and conventional electronic delay detonators. A control circuit in the IDC allows conventional detonators to be logged remotely by the blast machine. Elimination of manual logging by individuals increases safety in the blast zone and facilitates the blasting operation. Additionally, the detonators are powered on sequentially in a domino effect, which reduces the likelihood of a high surge current from the blasting machine that may occur when a large number of detonators are energized simultaneously. The logging operation is simplified, likelihood of human error is reduced, and the cost of a separate logger device is eliminated.

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.

An ignition safety device (ISD) used in an ignition system of a missile is configured to selectively control the ignition of two or more pulses or stages of a rocket motor propulsion system, based on a flight profile mode selection of a flight velocity mode, in which the missile is configured to travel at an optimized flight velocity, or a flight distance mode, in which the missile is configured to travel an optimized flight distance. The ISD is configured to selectively ignite the pulses or stages substantially simultaneously upon selection of the flight velocity mode, or in a delayed sequential manner upon selection of the flight distance mode. The ISD is also configured to selectively inhibit the delayed sequential ignition of the pulses or stages in the event of incidental ground or water impact of the missile after ignition of the primary pulse or stage.

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.
