20210404769 | CODED APERTURE SEEKER FOR NAVIGATION - A guided munition system includes a munition body including at least one fluid dynamic control for changing course of the munition body in flight. A seeker onboard the munition body is operatively connected to control the at least one fluid dynamic control. The seeker includes a coded aperture imaging device facing outward from the munition body for image based control for guiding the munition body in flight. | 2021-12-30 |
20210404770 | EYEWEAR LENS COUPLING SYSTEM - An eyewear lens coupling system and methods can be used during assembly of an eyewear. The system and methods may advantageously decrease optical distortion of the lens during assembly and use and/or may also advantageously increase retention of the lens to the eyewear frame to improve the overall quality of the eyewear. | 2021-12-30 |
20210404771 | BALLISTIC RESISTANT MATERIAL - A composite material system having an aggregate bound by an elastomer encapsulant. The composite material (CM) is designed to defeat impinging projectiles by converting the kinetic energy (KE) in the projectile to damage in the aggregate and the elastomer and increasing the thermal energy in the CM and the projectile via frictional heating. In one embodiment, the CM comprises certain kinds of rocks encapsulated (or bound) in a hyper-elastic polymer, such as polyurethane (“PU”). The CM may be shaped into convenient shapes from modular assembly to create a ballistic resistant surface. | 2021-12-30 |
