A method for detecting hardened bunkers within a target, the method including: producing a first output from a sensor fired to travel through the hardened bunkers, the first output being different from a second output when the sensor travels in a void between the hardened bunkers or encounters other objects outside of the hardened bunkers; and determining one or more of the number of hardened bunkers, a thickness of the hardened bunkers and a strength of the hardened bunkers based on the first and second outputs of the sensor over time. The sensor can include one of a piezoelectric generator for producing a voltage output and a circuit input by the voltage output or an accelerometer having a locking member for locking a proof mass during periods of impact with the one or more hardened bunkers.

The disclosure describes, in various example embodiments, a small arms or firearm projectile including a shell and a hemostatic material retained within the shell. The hemostatic material has a mechanical modulus above 25,000 Pa. In some embodiments, the shell includes a plurality of perforations. In some embodiments, the plurality of perforations are configured to provide, upon an impact of the projectile, fluid communication between the hemostatic material and the exterior of the shell via the plurality of perforations. In some embodiments, the hemostatic material includes a polymer core configured to provide a scaffold for inducing hemostasis in a local wound volume. In some embodiments, the projectile includes a contrasting agent. In some embodiments, the projectile includes a lubricating agent retained in the interior of the shell. In some embodiments, the projectile further includes 0.5 to 3 grains of Kaolin retained in the interior of the shell.

An impact-detection device includes at least one waveguide provided at each of the two ends thereof with a connector. The device further includes a ring with a curved outer contour. The ring forms a separate part with planar radial surfaces. The waveguide is built into the body of the ring about the ring, and the two ends of the waveguide are arranged on the outside of the ring.

An ordnance for air-borne delivery to a target under remotely controlled in-flight navigation. In one embodiment, self-powered aerial ordnance includes upper and lower cases. A plurality of co-axial, deployable blades is powered by a motor positioned in the upper case. When deployed, the blades are rotatable about the upper case to impart thrust and bring the vehicle to a first altitude above a target position. An explosive material and a camera are positioned in a lower case which is attached to the upper case. The camera generates a view along the ground plane and above the target when the ordinance is in flight. When the vehicle is deployed it is remotely controllable to deliver the vehicle to the target to detonate the explosive at the target. The ordnance may drop directly on a target as a bomb does.

A passive impact sensor for a projectile configured to explode, destroy with kinetic energy, embed or pass through an object with a closing velocity greater than 1,000 m/s. The passive impact sensor includes an energy generating system comprised of a crystalline structure that stores latent polarized electrical energy. The crystalline structure is responsive to an impact generated shock wave that propagates at least partially through the crystalline structure to consume and depolarize the crystalline structure and release at least a portion of the stored energy to generate a voltage pulse across output terminals. An onboard antenna is configured to transmit an RF pulse responsive to the voltage pulse (direct or integrated) external to the impact sensor (and projectile) before the sensor is destroyed by the shock wave. Multiple energy generating systems can be positioned either together or fore and aft and their voltage pulses summed to transmit the RF pulse. The benefits of this device include the ability to determine impact force, impact velocity, impact angle, target mass, target density, and direct or glancing impact.
