Abstract:
The ignition device according to the present disclosure implements in a reliable manner a one-time transient switching process for high voltages (>1.5 kV) and high currents (>3 kA) in combination with a minimal space requirement, maximum environmental durability and at the same time low cost expenditure by integrating the essential components on a flexible printed circuit system.
Abstract:
An explosives detonator system includes a detonator housing within which is provided a detonation circuit that includes a conductive pathway having a fuse head integrated therewith such that the conductive pathway passes along both electrodes and a resistive bridge of the fuse head. An uncharged chargeable voltage source is also integrated with the detonation circuit and is electrically sensitive to a charging property which is included in a charging signal. Exposure to the charging property charges the voltage source, thereby rendering it capable of generating a potential difference between the electrodes at least to equal the breakdown voltage of the resistive bridge. The charging property is any one or more of a charging light pulse, a charging temperature, a charging pressure and a charging radio frequency.
Abstract:
A duplex firing initiator for an airbag inflator includes both a primary initiator and a secondary initiator for electrical connection to a Restraint Control Module. In the duplex firing initiator, current is conducted in a forward polarity through the primary initiator to actuate the primary initiator and current is conducted in a reverse polarity through the secondary initiator to actuate at least the secondary initiator.
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:
An initiator for initiating detonation in a detonation cord of a perforating system, where the initiator comprises a modular electronic igniter that quick connects into a portion of high explosive. The high explosive is disposed in a housing having an end of detonation cord crimped therein. The electronic igniter may be shipped to the field and/or stored separate from the high explosive then the two may be assembled just prior to deploying the perforating gun assembly in a wellbore. Various methods of quick connecting the electronic igniter to the high explosive may be used.
Abstract:
An ignition element mounting capacitor having an ignition element mounted on a capacitor, includes therein a first capacitor section and a second capacitor section, and first external terminal electrodes electrically connected to the first capacitor section and second external terminal electrodes electrically connected to the second capacitor section. The first capacitor section has a capacity for igniting ignition powder, and the second capacitor section has a function for removing noise which affects external circuits. Further, provided on the surface of the capacitor are third external terminal electrodes electrically connected to the ignition element. In this manner, the invention provides a squib enabling its size to be miniaturized and its quality to be improved, while keeping a high productivity, and hence provides a header assembly and a ignition element mounting capacitor as components of the squib and further provides a gas generator having such a squib installed therein for an air bag and a gas generator having the squib for a seat belt pretensioner.
Abstract:
An initiator with a housing formed of plastic and a chip assembly for initiating at least one of a combustion event, a deflagration event and a detonation event. The chip assembly includes an electrically-actuated chip and a pair of electric leads that extend through the housing and are configured to couple the electrically-actuated chip to a fireset circuit. The electrically-actuated chip is partially encapsulated in the housing. A method for forming an initiator is also provided.
