  • Patent number: 11041683
    Abstract: The present invention, BullCharge, is a device that converts the charging handle of an AR, M4, or SR25 flat top rifle to a side charger. The BullCharger device is conveniently installed on either side of the Picatinny riser rail of the rifle using bolts and cap nuts through the slots on the flange of the BullCharger block. This installation does not require the removal of any existing components. By pulling the BullCharger handle backward, the rod within the block engages and pulls the rifle charging handle till the end. Subsequently, the BullCharger handle is released, causing the rifle charging handle to return. And a round is loaded to the chamber to set the rifle ready for use.

  • Patent number: 10782097
    Abstract: A device that causes a weapon to fire upon a target when the weapon is enabled by an operator, and when the weapon point of impact passes through a target or in a proximity thereto and when the target satisfies certain criteria as determined by one or more sensors/designations. The invention triggers the release of a round, multi-round burst, rocket, missile, or other projectile(s) when enabled by the operator, and when the target passes through the point of impact (or desired/computed proximity thereto), relieving the operator of the split second judgment in timing the release and/or cessation of such fire. The results include reduction in off-target rounds fired, increased hit rate, conservation of ammunition, more effective targeting for non-motion-stabilized weapons, and the introduction of a backup mode for nominally motion-stabilized weapons which may allow effective operations when primary stabilization systems fail or are overwhelmed by dynamics.

  • Patent number: 10696401
    Abstract: A dispenser for storing and launching countermeasures from an aircraft, comprising an elongate body provided with at least one launch opening adapted for storing the countermeasures in cartridges, where the dispenser comprises a manoeuvrable spoiler arranged in front of the launch opening, where the spoiler is adapted to be fully retracted before a countermeasure has been launched, and that the spoiler is adapted to extend outwards in a predefined manner when a countermeasure has been launched. The advantage of the invention is that a spoiler will reduce induced noise from the open cartridges by extending a spoiler outwards depending on the number of launched countermeasures. This allows for a simple, reliable and cost-effective solution.
