US12578171 - Expandable broadhead for arrow

A broadhead for an archery bow. The broadhead includes a member, a first blade, a second blade, and a magnet. The first blade and the second blade are coupled to the member. The first blade and the second blade form a plane. The magnet is at least partially disposed within the member. In some examples, the magnet has a longitudinal axis extending perpendicular to the plane. In some examples, each of the first and second blades have respective cutout regions interfacing the magnet while the broadhead is in a first configuration and/or a second configuration.

US12578172 - System and method for obtaining training munition firing signature

A training munition assembly for use with a weapon includes a case, a first firing element, and a release assembly. The case defines an interior cavity. The first firing element is disposed within the interior cavity. The release assembly is coupled to the case and engages the first firing element. The release assembly is configured to cause movement of the first firing element from a first position within the interior cavity to a second position within the interior cavity responsive to actuation of the release assembly from outside of the case. Movement of the first firing element is configured to generate a firing signature that is indicative of actuation of the release assembly.

US12578173 - Additively manufactured metal casings

An embodiment of the bomb casing ( 1 ) defines a generally conical nose portion ( 2 ) and a cylindrical body portion ( 3 ). At least one, and more preferably both, of the generally conical nose portion ( 2 ) and/or the cylindrical body portion ( 3 ) are formed from an additive manufacturing process, which is preferably cold-gas dynamic spraying of metal particles onto a support member. In one embodiment, the generally conical nose portion and cylindrical body portion are integrally formed.

US12578175 - Flight deck unit and safety supervisor for enhanced navigation, fuzing, and guidance of unmanned vehicles or projectiles

The present invention relates to navigation, fuzing, and guidance of vehicles, and more particularly to such capabilities for unmanned vehicles, drones, or other related systems. More particularly, the present invention is directed to a flight deck unit comprising sensors and electronics adapted to perform the navigation, fuzing, and/or guidance for such systems. Preferably, the flight deck unit is adapted for performing navigation, fuzing, and guidance in GPS denied or degraded environments and is immune to spoofing, jamming, and hacking, thereby providing safe and accurate navigation, fuzing, and guidance regardless of the arena or environment. Further, the invention is directed to a system for providing safety supervision of weapons systems on vehicles or projectiles. More particularly, the safety supervision is adapted for ensuring that weapon-level safety measures are unable to be disengaged while the vehicle or projectile is within a safety zone.

US12578193 - Multi-IMU guidance measurement and control system with handshake capability to refine guidance control in response to changing conditions

Presented herein are systems and methods using inertial measurement units (IMUs) for providing location and guidance, and more particularly for providing location and guidance in environments where global position systems (GPS) are unavailable or unreliable (GPS denied and/or degraded environments), and for such location and guidance being provided to projectiles, munitions, or rounds that are released, fired, or deployed from vehicles or weapons systems. More particularly, this disclosure relates to the use of a series of low-accuracy or low-resolution IMUs, in combination, to provide high-accuracy or high-resolution location and guidance results. This further relates to an electronics-control system for handing off control of the measurement and guidance of a body in flight between groups or subgroups of IMUs to alternate between high dynamic range/lower resolution and lower dynamic range/higher resolution measurement and guidance as the environment dictates.
