The present disclosure relates to an apparatus and method for controlling detonator blasting based on a danger radius, the apparatus including a danger radius setting unit that sets a danger radius for a detonator or a communication module, a blasting area setting unit that sets a blasting area in which a preset danger radius is reflected in a location value input during registration of the detonator or the communication module, an equipment location determination unit that determines a location of equipment possessed by an operator, and a blasting start control unit that controls so that blasting of the detonator is allowed only when the equipment is not located within the set blasting area as a result of the determination.

The present invention provides an improved sorbent and corresponding device(s) and uses thereof for the capture and stabilization of volatile organic compounds (VOC) or semi-volatile organic compounds (SVOC) from a gaseous atmosphere. The sorbent is capable of rapid and high uptake of one or more compounds and provides quantitative release (recovery) of the compound(s) when exposed to elevated temperature and/or organic solvent. Uses of particular improved grades of mesoporous silica are disclosed.

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 non-detonable shaped charge capable of becoming detonable upon activation. The shaped charge may be utilized for use with a perforating gun in oilfield applications. In this regard, during transport and other handling in advance of reaching the application site, the charge may be non-detonable. However, upon an intentionally directed activation, such as through heating, the shaped charge may be detonable.

An apparatus and method for protecting exposed threads of a material. The apparatus having a base, a body with at least one open end, and at least one protrusion. The protrusions may be spaced evenly along an inner or outer surface of the apparatus body at a fixed distance from the base. Additionally, the protrusions can be matched to a thread pattern to allow for quick attachment, or connection. The apparatus may be constructed of a metallic material or alloy, or a combination of metallic materials and alloys. The thread protector thread pattern can then be matched to the thread pattern on the material or item to be protected. Affixing the thread protector to the material or item to be protected could include turning the thread protector in a manner that secures, connects, or locks the protrusions with the thread patter of the material or item to be protected.

Detonation control modules and detonation control circuits are provided herein. A trigger input signal can cause a detonation control module to trigger a detonator. A detonation control module can include a timing circuit, a light-producing diode such as a laser diode, an optically triggered diode, and a high-voltage capacitor. The trigger input signal can activate the timing circuit. The timing circuit can control activation of the light-producing diode. Activation of the light-producing diode illuminates and activates the optically triggered diode. The optically triggered diode can be coupled between the high-voltage capacitor and the detonator. Activation of the optically triggered diode causes a power pulse to be released from the high-voltage capacitor that triggers the detonator.
