A coupler for coupling shock tube to a disrupter cannon so that the shock tube automatically decouples from the coupler and thereby from the disrupter cannon after the disrupter cannon has been fired to launch a projectile. The coupler retains the shock tube with a force that is greater than the force provided by the shock tube when it is ignited, but is less than the force of a reflected wave of pressure out of the disrupter cannon after the disrupter cannon has been fired.

A firearm synchronized discharge device for facilitating a synchronized discharge of two or more firearms are described together with associated systems, firearms and methods. The device includes an actuator for engaging with a movable trigger of a first firearm, a sensor configured to generate a signal indicative of a force applied to the trigger and a first controller operatively coupled to the sensor and to the actuator. The actuator is configurable between a first configuration that prevents movement of the trigger toward a firearm-discharge position of the trigger, and a second configuration that permits movement of the trigger toward the firearm-discharge position of the trigger. When the force meets a criterion and the one or more other firearms are ready for discharge, the actuator is caused to transition from the first configuration to the second configuration to permit actuation of the trigger and discharge of the firearm.

One example insect release device includes a vessel defining a volume, the vessel has first and second surfaces substantially opposite each other, the first surface defining an opening into the volume; a population of insect larvae or pupae or adult insects within the volume; and a seal positioned to obstruct the opening and adhered to the first surface. Another example insect release device includes a vessel defining a volume; a population of insect larvae or pupae or adult insects disposed within the volume; wherein the vessel is permanently sealed, and wherein release of the insect larvae or pupae or adult insects occurs upon rupture of the vessel. A further example insect release device includes a vessel defining a volume; a population of insects disposed within the volume; and a gimbal mechanism coupled to the vessel, the gimbal configured to maintain a substantially constant orientation of the vessel.

A multi-detector chronograph system incorporated with a firing device for launching projectiles along a passage for direction of projectiles. The firing device has at least one control device for regulation of at least one configuration of the firing device. A measuring device with multiple detectors is configured to sense moving projectiles moving along the passage or leaving the passage. The measuring device is configured to produce data in relation to the sensed moving projectiles. A control unit is provided for handling the data and producing an indication for adjustment of the control device.
