Abstract: A wireless electronic detonator includes a primary source of energy and at least one functional module. A power switch is disposed between the primary source of energy and the functional module to connect or disconnect the functional module and the primary source of energy. A controller controls the power switch and includes an optical receiver to detect and demodulate a light signal emitted by a control console, The controller generates a control signal according to the demodulated light signal to at least control the power switch. A wireless detonation system includes the wireless electronic detonator and the control console configured to emit a light signal, and method for activating the wireless electronic detonator.

Abstract: The present invention is directed toward an addressable ignition stage which produces an output sufficient to detonate a secondary explosive, generally. The present invention comprises addressability and ignition functions that may be used together or separately to incorporate a high-power resistor with a thermally conductive substrate allowing for operation at high temperatures for ignition. The ignition stage is amendable to high volume production, exhibits a high degree of reliability, robustness and operational dependability for use alone or configurable into existing technology.

Abstract: An electronic ignition circuit may include a logic circuit and an ignition circuit electrically coupled to the logic circuit. The logic circuit may include a microcontroller and a switching circuit configured to switch from a first detonator or igniter to a second detonator or igniter in response to a signal from the microcontroller. The ignition circuit may include a capacitor discharging circuit configured to discharge a firing capacitor through a fuse head. The capacitor discharging circuit may include an ignition switch configured to remain actively closed after the firing capacitor is discharged through the fuse head.

Abstract: A device and a method thereof for operating a stemming rod used for the blasting and configured to include an information collection function are proposed. The device includes a stemming material information collection unit configured to collect stemming material information including information related to energy applied and compaction counts when filling a stemming material into a blast hole, from a sensor built into the stemming rod used for the blasting, a communication-performing unit configured to perform wireless communication with a detonator to be charged through a communication module built into the stemming rod used for the blasting, and a blasting time controller configured to control a blasting time on the basis of detonator information and location information of the stemming rod used for the blasting, the information being collected from the communication-performing unit.

Abstract: An initiator circuit for a perforating gun includes a microprocessor structured to perform a circuit-startup algorithm comprising determining whether the circuit supply voltage is stable enough for operation and, if it is, or if a predetermined period of time has passed since powering up the circuit, sending a message indicating the circuit (and thus gun) is ready for operation. The sent message may be a communication uplink indicating an address of the circuit and its ready state or a short burst of pulses indicating the circuit's ready state.

Abstract: A ground-fixable electronic detonation device for a blasting system and a blasting system using same are proposed. The ground-fixable electronic detonation device includes: an electronic detonator; a wireless communication module; a wire part configured to connect the electronic detonator and the wireless communication module; and a module fixing pin part positioned in the wireless communication module and configured to move upward and downward to be driven into the ground. In the ground-fixable electronic detonation device, the module fixing pin part is driven into the ground to stably fix a position of the wireless communication module, so that stability in wireless communication is secured. Accordingly, blasting accuracy may be improved.
