    Abstract: An assembly can include solid-state overvoltage firing switch operable to control an explosive device. The solid-state overvoltage firing switch can include a substrate layer. The solid-state overvoltage firing switch can also include a conductive anode and a conductive cathode positioned on the substrate layer. A gap can physically separate the conductive anode from the conductive cathode. The conductive anode can be operable to receive a voltage from a power source. The solid-state overvoltage firing switch can further include an insulator layer adjacent to the conductive anode and the conductive cathode. At least part of the insulator layer can fill the gap. The insulator layer can cover a first portion of the conductive anode and a second portion of the conductive cathode.

    Abstract: A blasting system with automated detonator logging eliminates on-the-field manual logging of each detonator. Detonators are connected in sequence in an auto-logging circuit, and the blast machine initiates a logging operation in which each detonator receives and confirms an assigned sequence number along with assigned delay data. Elimination of manual logging by individuals increases safety in the blast zone and facilitates the blasting operation. The operation is simplified, likelihood of human error is reduced, and the cost of a separate logger device is eliminated. An auto-logging protocol may be incorporated into the control module of the electronic detonator. Alternately, an auto-logging module may be connected externally to each detonator similar to the conventional surface plus down-the-hole delay systems. The inventive system may include an IDC connector that facilitates the serial connection of the detonators for the logging circuit while allowing parallel connections of the blast control circuit.

    Abstract: A detonator system is provided for use with explosives that utilizes two subsystems. A first subsystem functions as a non-explosives based detonator, which does not contain any explosives. The second subsystem is an initiating subsystem, which includes an initiating pellet. To set off an explosive event, the non-energetics based detonator is coupled to the initiating subsystem and the non-energetics based detonator is commanded to provide a suitable signal to the initiating subsystem that is sufficient to function the initiating pellet. Further, the initiating subsystem can be integrated directly into an associated explosive such as a booster that has been configured to receive the initiator subsystem without changing the hazard class of the booster.

    Abstract: A remote initiator breaching system for initiating breaching charges over a short range requiring no physical link between the breacher and the demolition charge. The remote initiator breaching system has at least one transmitter, at least one receiver, at least one shock tube connectable to a breaching charge and a power source for each of the transmitter and receiver. The transmitter is able to generate and transmit a coded signal. The transmitter has an input for inputting operational commands into the transmitter for generating the coded signal, The transmitter has a plurality of channels representing different frequency bands, and multiple addresses for each channel such that transmission of the coded signal from the transmitter to the receiver is possible per individual addresses or all addresses simultaneously.

    Abstract: An explosives detonator system for detonating an explosive charge with which it is, in use, arranged in a detonating relationship is provided. On acceptance of a detonation initiating signal having a detonation initiating property, the system initiates and thus detonates the explosive charge. The system includes an initiating device which accepts the detonation initiating signal and initiates and thus detonates the explosive charge. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. The system also includes a radio frequency identification (RFID) based switching device that detects a switching property of a radio switching signal that is transmitted to the detonator system and switches the initiating device, on detection of the detonation initiating property, to a standby condition in which the initiating device is capable of operatively accepting the detonation initiating signal when it is transmitted thereto.

    Abstract: A circuit includes a line input for receiving a line power. The circuit further includes a line output for transmitting the line power. The circuit further includes a next-gun-detect output and a next-gun-detect input. The circuit further includes a first detonator connection and a second detonator connection, the second detonator connection being connected to a ground. The line input is coupled to the first detonator connection through a one-polarity-pass component that only allows power of a first polarity to pass. The line input is coupled to the first detonator connection through a detonate-enable switch circuit that is coupled to the next-gun-detect output and the line input. The detonate-enable switch passes power only if (a) the next-gun-detect output is not coupled to the next-gun-detect input and (b) power of a second polarity has previously been applied to the line input while the next-gun-detect output is not coupled to the next-gun-detect input.
